There is no longer any reason not to release the well data to public files as per your normal release date,or as soon as feasible if that date has already lapsed as we considered their earlier request.

We note that they drilled both the initial well (PTD 213-071,API#50-083-20003-00-00) and a sidetrack(PTD 213-108,API#50-083-20003-01-00), and we assume their request pertains to both. DNR has not yet determined a response.

The Nunivak#2 well will be drilled by Doyon Ltd. and is scheduled to spud near mid-July, 2013. Although formation water is estimated to be less than 3000 ppm salinity above about 3720' at the well site, permission for annular injection is requested because shallow formation water at the drilling location exceeds Federal Maximum IContamination standards and all existing water wells are farther than 10 miles distant. Summarized here and addressed below, the data indicate these points: I1. Subsurface water salinity exceeding 3000 ppm is not reached until a depth of approximately 3720' (-3330' '' Tvdss) in the Nunivak#1 well based on analysis of the resistivity log and water saturations. Nunivak#1 is the I only deep well in the deeper part of the Nenana basin and is located about 7 miles east of the Nunivak#2. 2. Although depth of permafrost is estimated at about 1800' at Nunivak#2 based on seismic data,water I occurs as shallow as 94' in the nearby Nenana Agricultural Project test well. A 340' water supply well at the Nunivak#2 location also found shallow water in adequate supply for the well site. All other existing water wells are 10 miles or more distant from Nunivak#2. I 3. Water analysis from the water supply well at Nunivak#2 indicates total salinity of about 200, but with elevated levels of As (11.8 ppb) and Fe (3.61 ppm) that exceed Federal Maximum Contaminant levels of 10 ppb and 0.3 ppm, respectively. 1 4. Annular injection of 9000 barrels in a 100'vertical zone beneath surface casing will invade the formation about 23' in a symmetrical radius around the well bore. Injection over a 200' vertical distance reduces the I symmetrical radius of the injected volume to about 16'. 5. Review of the Nunivak#1 drilling results and inspection of seismic velocity and amplitude data show no indication of shallow gas hazards near Nunivak#2. I 1 ORIGINAL 1 Discussion • • I 1. The formation comprising the near surface section in the Nenana basin is known as the Nenana Gravel. The Nenana I Gravel consists of clastic rocks, mostly sands and gravels, which are water saturated in the subsurface in Nunivak#1. Figure 1 shows the location of Nunivak#1 and the drill location for Nunivak#2, scheduled to spud in mid-July. Ray I Eastwood (report in Appendix 1) examined the resistivity and other logs and concluded subsurface water salinity v does not rise above 3000 ppm until a depth of approximately 3720' (-3330'Tvdss) with an accuracy of+/-20 vertical feet. Salinity rises quickly from 1700 ppm at 3675' to 4100 ppm at 3775'. The threshold of 3000 ppm salinity is I crossed at about 3720' within this salinity gradient. Figure 2 shows the subsurface log response in the zone of interest. The leftmost curve (pink) in Track 1 is calculated I salinity and it reflects the strong change in resistivity shown in Track 3. I 2. A test well for the Nenana Agricultural Project was drilled in 1981 to a depth of 193'. Water was found in this well, but no chemical analysis of a water sample has been found. Figure 3 shows the drilling log for this well with the I description of the water-bearing sands. Water is noted on the drilling log for the Nenana Agricultural Project test well in a "water-bearing, slightly silty to silty, I fine SAND" that begins at a depth of 94'. The interval described as water-bearing extends from 94' to 175'. This test well has been suspended or abandoned. I A water supply well was drilled at the Nunivak#2 location to a depth of 340' and found sufficient water for well site purposes. I All other water wells are 10 miles distant or more from Nunivak#2 and are located in the general vicinity of the town of Nenana. A report by Alicia Orange detailing existing water wells can be found in Appendix 2. Salient points are all I existing water wells are more than 10 miles distant from Nunivak#2 and no existing water well extends beyond 380' depth below surface. I 3. A water supply well was drilled at the Nunivak#2 location in early 2013 to supply water for upcoming rig I operations. TD is 340' and the drilling log is shown in Appendix 3. The drill log shows that frozen sediment was encountered from surface to 255'. Water zones were drilled from 255-270' and 315-340'. The two water zones are separated by frozen sand from 270-315'. Ten inch casing was set to a depth of 315' and a production screen was I installed from 315-330'. Water flow was gauged up to 1000 gpm. The tested water flowed from the deeper water- bearing interval (315-340'). I Analysis shows this water is elevated in As and Fe above Federal Maximum Contamination standards (Appendix 4) with metal contents as follows. I As Fe TDS 1 Water sample 11.8 ppb 3.61 ppm 200 ppm Federal Maximum 10.0 ppb 0.3 ppm ll .IA1010190 21 I 0 • I No additional analyses are available for water from the Nenana Agricultural Project test well or from shallow water wells • west of Nenana River. I 4. Approximately 9000 barrels of fluid waste is expected during the drilling of Nunivak#2. Clay-corrected density and ' I neutron porosity logs (Figure 4) indicate about 30-35% porosity at about 2700' in Nunivak#1. Generally similar porosities are expected in Nunivak#2. Given 30% porosity, an injected volume of 9000 barrels over a 100' vertical section will invade the formation to a radius of 23' if invasion proceeds symmetrically in all directions around the / Iwell bore. Expanding the injection zone to 200' reduces the radius of the injected volume to about 16' if invasion proceeds symmetrically. I 5. Inspection of the near surface seismic data shows no indication of shallow gas hazards at Nunivak#2. An extensive I memo on this subject from Mike Helton to Steve Davies is dated May 28, 2013. The first page only of this memo is included in Appendix 5. I I I I I I I I I I I 3 i 1 Figure 1. Location of Nunivak#1, Nu Oak#2, and the town of Nenana.

The logging runs are composed of wireline logs (Schlumberger) to a depth of about 7650 feet; neutron and density logs were recorded to a depth of 7550 feet while the resistivity logs were recorded to a depth of 7620 feet. Below casing, deep resistivity reading vary from over 200 S2m at a measured depth of about 2550 feet (-2180 feet TVD55) to approximately 10 12m at about 3750 feet (-3370 feet TVD55). Below this depth, resistivity values are relatively - ' uniform, with limited streaks that exhibit higher resistivity, to a depth of about 5850 feet (-5430 feet TVD55). Above a depth of 3750, resistivity values increase from about 10 12m to over 40 S2m in a vertical distance of about 200 feet. As we believe the interval to be fully water-saturated, . this variation of resistivity suggests freshing of connate water vertically. To assess possible variation in salinity, an RWA analysis was done that uses an Archie 5w model and porosity computed based on the density log. Based on Donna Messer's provisional geologic tops (PRA Wel!site Geologist Final Well Report_8_18 _09.doc), the interval of interest is contained within the Nenana Gravels; the Grubstake fm. begins at about 4017 feet. Within the Nenana Gravels, response of the GR, RHOS, NPHI and DT logs are reasonably uniform. GR values vary from about 35 to 60 api with limited intervals, perhaps 5 to 10 feet thick, that exhibit GR values of about 85 to 100 api; these higher GR intervals correlate with lower resistivity values and thus likely reflect clay-rich layers in the Nenana Gravels. RHOS log values vary from about 2.05 to 2.3 g/cc while NPHI varies between about 0.35 to 0.45 v/v. ' Our analysis of these logs applies borehole corrections to the density and GR logs. The RHOS log was converted to sandstone porosity, the matrix used in recording the NPHI log, which also reflects the lithology of the Nenana Gravels. There is a good correlation between VCLAY_&R, clay volume from linear GR index, and ON - OD (neutron minus density porosity) which supports the notion of relatively simple variation of clastic lithology. Clay volume using ON - OD was computed (VCLAv_ND). An estimate of VCLAY is the average of VCLAv_&R and VCLAV_No; which varies between about 0.05 and 0.2 v/v through the interval of interest. Although perhaps unnecessary, 'D was corrected - for clay volume (i.e. hoc = 'o - OD CLAY VCLAY, where OD CLAY = 0.05 v/v) and this porosity is used to compute RwA. On average, clay-correction decreases OD by about 0.005 v/v (0.5 Pu). Typically, OD varies through the Nenana Gravel between about 0.25 and 0.30 v/v (25 and 30 Pu). From the perspective of causing systematic error in RWA estimate based on this porosity, these high values argue for limited error. Formation temperature was computed using F_Temp (°F) = 60.0 + 0.0115 (-TVD55) and is based on 5 of 7 temperatures measured during logging (2 high temperatures were omitted from for regression estimate, see chart below). RwA values were converted to salinity using an algorithm , based on the Schlumberger Chartbook chart Gen-9; this includes using the APS equation to A logplot to be referenced for this discussion is found as GGX(server08): Doyon/Nenana_08/User Files/reastwood/Nunivak_1_wsalinity.jpg. 8 ' .

Salinity values (in Correlation track, shaded where below 3,000 ppm) computed in the lower Nenana Gravels below about 3875 feet (-3500 feet TVDSS) are above about 5,000 ppm (RwA F_Temp < ✓ 0.8 f2m; RwA curve is located in Resistivity track, the lower black curve). Above this depth, apparent salinity values decrease to about 4,100 ppm at 3775 feet (RwA © F_Temp = 1.02 f2m) and ' to below 1,700 ppm at 3675 feet (RWA © F_Temp = 2.35 f2m). This identifies a salinity gradient of approximately 1,000 ppm decrease in 100 vertical feet. As viewed in a logplot, a salinity of 3,000 ppm (RwA © F_Temp = 1.44 f2m) occurs at a depth of about 3720 feet (-3330 feet TVDSS). At depth shallower than 3625, apparent salinity values are less than 1,000 ppm (RwA F_Temp > 4.15 f2m). Given that this salinity gradient of about 1,000 ppm/100 feet is substantial, there is little doubt of its existence. And depth estimates of exactly where salinity drops below 3,000 ppm are likely within 20 vertical feet or less. RayEastwood: May2013 I 9 r • I Appendix 2 Summary of Water Wells and Aquifer Information in the Nenana Area I Research has been undertaken to characterize the fresh water aquifers in the Nenana Basin in response to a request I from AOGCC Sr. Petroleum Geologist, Steve Davies. Although detailed characterization of aquifers in Nenana is not possible due to lack of data, all available information was gathered and incorporated in this study. A search was conducted on public domain DEC and DNR databases in order to find any information on the aquifer in the Nenana area. Water well locations and depths from these databases and a review of Nunivak#1 logs and water well data near the I proposed Nunivak-2 location support the following conclusions: • Water salinity<3000 mg/I is estimated to extend down to -3330'TVDSS in the Nunivak#1 well I • Closest drinking water wells are > 10 miles from Nunivak#2 location, in the village of Nenana • No water well in the basin extends beyond 380' below surface level • A water supply well drilled to support the Nunivak#2 drilling operation tested above regulatory maximum for iron and arsenic . • A suspended or abandoned test water well was drilled for potential agricultural use approximately 1.3 miles I from the Nunivak#2 location. Formation water salinity 1 Analysis of the well log data from the Nunivak#1 well, conducted by Ray Eastwood, estimates a depth to the 3000 mg/I • salinity level at-3330'TVDSS, +/-20'. This analysis is discussed in a separate technical memo. I Water wells in the basin Two sources of public domain data were used in the search for information on the Nenana area aquifer. A copy of the Il • table from DNR-Mining, Land &Water's Well Log Tracking System (WELTS) for the Nenana area is shown (next page). Note that seven of the eight wells listed on the table are located in T3S-R7W or T4S-R8W, in the town of Nenana or I vicinity; the Nenana Agricultural Project well is the only well listed that is west of the Nenana River(refer to the map on • page 3).The depths of the water wells on this table range from 40 to 380 feet. Due to the distance from the Nunivak-2, a search for water quality reports for the wells in the vicinity of the town of Nenana was not undertaken.

I Nunivak#2 water supply well I A water supply well drilled in March, 2013 adjacent to the location of the proposed Nunivak-2 exploration well (see diagram, below). The water well is 340 feet deep. The water analysis report(see appendix) shows levels of arsenic and I ' iron that exceed the maximum contaminant level (arsenic= 11.8 ug/L; max. contaminant level 10 ug/L; iron = 3.61 mg/L; max. contaminant level 0.3 mg/L).

Agricultural well A water well listed in the DNR-Mining, Land &Water's Well Log Tracking System (WELTS) database, the "Nenana I Agricultural Project" water well owned by the State of Alaska DNR-DGGS,turned up in the Nenana data search. It is located approximately 1.3 miles to the northwest of the proposed Nunivak-2 location (see map on page 3). It was a test I well drilled to 193 feet in 1981 as part of several studies that were conducted for the Nenana Agricultural Project.The log/as-built document from DNR-MLW-WELTS is included in the appendix. Since the project never got underway, the water well was not used (personal communications, Roy Ireland, DNR-Div. of ML&W, and Dan Proulx, DNR-Div. of IAgriculture, 6/10/2013). A water analysis report for this well was not available in the DNR-MLW WELTS site. I 13 III ! 1 Appendix 3 I ARCTIC DRILLING, INC.

PRA personnel reviewed the previous Nunivak#1 drilling hazards report,2D seismic data,seismic velocity information, and offset well logs in completing the shallow hazard and pore pressure risk analysis of this well.. Evaluation of this data shows no indications of drilling hazards or risks. The Nunivak-#2 drilling engineer reports the drilling program for the Nunivak-,--7,2 will be similar to the plan successfully executed for the Nunivak#1. The Nunivak-#2 drilling plan acknowledges the possibility of encountering shallow drilling hazards and incorporates processes to mitigate those risks while drilling. The logs and drilling data used for this analysis were taken from the Nunivak-#1 well(Fig.1). PRA examined migrated time 2D seismic data and stacking velocities from the Doyon Nenana area 2D seismic data(Fig. 2). Permafrost.Gas Hydrates.Shallow Gas From an analysis of seismic stacking velocities.the base of permafrost was predicted to be at a depth of 1300'MD(--!- 150')in the Nunivak#1_ The drilling engineer reported that the base of permafrost was encountered in the Nunivak--,1 at approximately 2200'MD. Examination of the seicnnic stacking velocities near the proposed Nunival5t2 location suggest a shallower depth to ' the base of permafrost encountered in the Nunivak-41 well(Fig. 3).

Dink proceeded to tell me that they have a stage collar — at approximately 315'. I asked Dink if their well plan that was submitted to AOGCC and approved for their PTD had the opening of their stage tool and cement to surface as the plan forward if cement to surface was not achieved on the first stage. Dink answered that it was.They pumped approximately 75 bbls 15.7 ppg tail cement on first stage that is presently setting up (hopefully).The only thing I could think of I could add was that it seemed appropriate to open stage collar and establish circulation for second stage cement to surface. Our conversation turned into 48 hour notification for BOP test. I made both WSL's aware of the process for notification to the AOGCC and that guidance for notification and notification document were both on AOGCC website. Dink stated that they have drill pipe management to perform if needed prior to test BOP's. They are aware that this is a very important test for us to witness and they were reminded that travel was difficult and they would be asked to perform pre tests and possibly pipe management to allow us to witness this test. Hopefully this is appropriate. ri OF Tit, • 111 1//7,- ",s.� THE STATE Alaska I and Gas f)fA LAsKA Ci riservationissi®n 1/4 , GOVERNOR SEAN PARNELL 333 West Seventh Avenue Anchorage, Alaska 99501-3572 ALAS Main: 907.279.1433 Michael Cook Fax: 907.276.7542 Operations Manager Doyon, Limited 1 Doyon Place, Suite 300 Fairbanks, AK 99701-2941 Re: Exploratory Field,Exploratory Pool,Nunivak#2 Doyon,Limited Permit No: 213-071 Surface Location: 1281' FNL, 1200' FWL, SEC. 7, T4S, R9W, FM, AK Bottomhole Location: 1281' FNL, 1200' FWL, SEC. 7,T4S, R9W, FM, AK Dear Mr. Cook: Enclosed is the approved application for permit to drill the above referenced exploration well.

Annular Disposal(AD)requires separate sundry approval(10-403AD). Regulation 20 AAC 25.071(a)authorizes the AOGCC to specify types of well logs to be run. In addition to the well logging program proposed by Doyon, Limited in the attached application, the following well logs are also required for this well: Mud log and samples from base of conductor to T.D. This permit to drill does not exempt you from obtaining additional permits or approvals required by law from other governmental agencies, and does not authorize conducting drilling operations until all other required permits and approvals have been issued. In addition,the AOGCC reserves the right to withdraw the permit in the event it was erroneously issued. A weekly status report is required from the time the well is spudded until it is suspended or plugged and abandoned. The report should be a generalized synopsis of the week's activities and is exclusively for the AOGCC's internal use. Operations must be conducted in accordance with AS 31.05 and Title 20, Chapter 25 of the Alaska Administrative Code unless the AOGCC specifically authorizes a variance.

Drilling Hazards & Contingencies: o Stuck Pipe o A "stuck pipe" event occurred in the Nunivak#1 well at TD (11,135' and/11,074 ft. tvd/rkb). The stuck pipe root cause was determined to be coal ledges/interference as the drill string was attempted to be POOH at TD. o Usibelli Coal Interval(s) o Grubstake/Lignite Creek : Coal beds are present in the Grubstake Formation and increase in frequency downward into the Lignite Creek interval. o Sanctuary : Thin coal sections are noted, section is predominately claystone (shale). o Healy Creek : The Healy Creek Formation in Nunivak#1 had the most and thickest coals of the Usibelli Group. More than 30 coal beds from 2' to 18' in thickness were drilled. o Late Paleocene Interval o Coals are present and common in the upper 2000 ft of the late Paleocene interval. o Coal sections diminish significantly at 2400 ft. tvd below the top of the late Paleocene interval. o Nunivak#2 surface 10-3/4 45.5 L80 BTC casing will be set a 2700 ft. and/tvd. A pronounced shale interval is observed in the Nunivak#1 well at 2700 ft. and/tvd. Noting that Nunivak#1 did not record cement to surface during the surface 9-5/8" 40# L80 BTC primary cementing displacement (Casing Point : 2513 tvd/md). A staged/ported collar was utilized to displace lead cement to surface. o Sanctuary Formation/Bit Balling : The Sanctuary formation composed of mostly claystones (shale) caused significant bit balling while being drilled in the Nunivak#1, 9-7/8"production hole section. 7 • • • o The Nunivak#2 9-7/8"production hole section, TD is planned for 12,000 ft tvd/md (rkb).. Noting that the Nunivak#1 (August/2009)was TD'd @ 11,135 md./11,074 tvd(rkb). The Nunivak#2 well bore will be drilled an additional 900 ft. vertically to the planned well total depth(TD). o A contingency 4-1/2" 12.6#L-80 BTC-M (2000 ft.) liner will be staged at the Tubular Solutions Alaska(TSA) yard in Fairbanks. o Loss Circulation material(s) inventories should be on location and sufficient to mitigate an initial as well as secondary loss circulation event. The Baroid Drilling Fluid engineer is expected to manage this inventory and its immediate accessability. Expected Pressures , • A 9.6 lb/gal equivalent pore pressure is expected to exist at total depth, equating to a bottom-hole pressure of 5990 psi at 12,000 ft.md/tvd-rkb. • Attention to drilling mechanics (torque, p.u. weights ,s.o. weights, rop, on bottom rotating wts.) surface rig system(s) (active system pit volumes, hole fill on trips) and real time L/MWD data is critical to successfully manage the formation transitions and pore pressure regimes while drilling the 9-7/8"production hole section. Hydrocarbons: • As noted in the preceding table,"Formation Markers : Nunivak#2". The Suntrana, Sanctuary and Late Paleocene formations are considered prospective hydrocarbon(gas and/or oil)bearing formations. Faults • No fault intersections are expected. Hydrogen Sulphide • The Nenana Exploration License area is not designated as H2S area. H2S is not expected. Distance to Nearest Well: • The Nunivak#1 exploration test well drilled and P&A in August 2009 is 6.8 miles distance from the Nunivak#2 well site. The Nunivak#2 is planned as a vertical test well. 8 • I Nunivak#2 Drilling, Evaluation & Complete: 1. MIRU the Nabors 105E drilling rig on the pre-installed Nunivak #2 , 16" conductor/cellar .

The Expected Thickness of the formations was calculated from these seismic picks and further adjusted by the stratigraphy encountered in Nunivak#1. This particularly applies to the expected thickness of the Lignite Creek and Healy Creek Formations. Coal beds are present in Nunivak#1 in these formations: Grubstake, Lignite Creek, Sanctuary, Healy Creek, and Late Paleocene. Coal is thickest and best developed in the Sanctuary, Healy Creek and Late Paleocene Formations. No coal was detected in Nunivak#1 in the Nenana Gravel and coals in the Grubstake and Lignite Creek Formations are thin. The near-surface sediments are probably clay, sands and gravels related to recent glaciation and reworking by the Tanana River. Their thickness is unknown at the drilling location, but might be on the order of 50'. No significant discontinuity is expected between the surface sediments and the Nenana Gravel. The following is a discussion of the stratigraphic characteristics of each formation expected at Nunivak #2. A description of the outcrop characteristics of each formation is followed by a discussion of the formation characteristics in the Nunivak#1 well. Source of much of the material in the outcrop discussion is from Wahrhaftig et al (1969) and Ridgway et al (1999). i Nenana Gravel The Nenana Gravel is a coarse clastic unit composed of sandstone and conglomerate. Ridgway et al (1969) measured 2300' of Nenana Gravel in outcrop and show the lithology as dominanted by conglomerate with subordinate sandstone. Two mudstone units about 20'thick are described in the lower part of the Nenana Gravel. The sandstone is lithic-rich with lithic fragments slightly more abundant than quartz. The Nenana Gravel was deposited by alluvial fans spreading northward from the rising Alaska Range. No coal was described in outcrop. In Nunivak#1 the Nenana Gravel was logged as primarily sand with 10%or less conglomerate. Above 400' depth, conglomerate is logged at 20-30%with sand being the remainder. No coal was logged in Nunivak#1 in the Nenana Gravel, although occasional wood or lignite grains were noted. Grubstake Formation Outcrop: The Grubstake Formation includes dark claystone, dark sandstone and fine conglomerate (Wahrhaftig et al, 1969). It underlies the coarse conglomerate of the Nenana Gravel which usually is conformable over the Grubstake. In outcrop,the Grubstake is 600-1,000'thick at the type locality along Tatlanika Creek, but the widespread Grubstake is up to 1,500'thick elsewhere. The Grubstake contains little coal with coal beds a maximum of 1'thick. The Grubstake accumulated in a lacustrine environment, claystone is typically thin bedded or varved, and sedimentary structures suggest a southerly source. Beds of sandstone from 3-40'thick and conglomerate is interbedded with claystone. The Grubstake is probably a transitional unit between older south-flowing drainage to younger north- flowing drainage with uplift of the Alaska Range. In outcrop,the lower Grubstake occasionally contains ash beds that are sometimes thin, but up to 40'thick. The thin ash beds weather to clay-rich, chalky layers. Nunivak#1: The top of the Grubstake is marked at the first significant coal and claystone. Lignite composes up to 50%of the cuttings for a few 10's of feet at the top of the Grubstake in Nunivak#1. Overall,the Grubstake cuttings in Nunivak#1 are described as about 45%sand, 45%clay, and about 5- 10% coal. The GR log indicates the Grubstake has significant clay content which indicates it could be a subsurface seal for migrating fluids. Thin sands in the Grubstake could contain hydrocarbons if charged and sealed. Lignite Creek Formation Outcrop: The Lignite Creek Formation is about 540'thick in the type section at Suntrana Creek and consists of interbedded buff sandstone, greenish-gray claystone and thin coal beds. The coal beds pinch out to the north and west of the coalfields and the Lignite Creek Formation in these localities lacks coal. • • In the coalfields,the Lignite Creek is a repeated fining-upwards sequence of sandstone, claystone, and coal. The top of each sequence has several thin coal layers interbedded with claystone. These represent shallowing upward of the depositional environment. Sandstone units in the coalfields are up to 160' thick, some are laterally persistent and others grade laterally into claystone or lens out. Sandstone color is buff and is composed of an abundance of multi-colored grains,which differs from the salt and pepper sandstone of the underlying Suntrana Formation. Pebble layers and conglomerate make up 20-50%of the lower parts of some sandstone units and conglomerate lenses can be up to 20'thick. Coals in the Lignite Creek Formation are thin and discontinuous and difficult to correlate. The non-coal facies of the Lignite Creek is about 250'thick and increases to 1,000-1,300'to the north of the coalfields. Current directions are typically to the south indicating a clastic source to the north from the Yukon-Tanana terrane. Nunivak#1: The Lignite Creek Formation in Nunivak#1 is logged as about 85%sand, 10%clay, and 5% coal. The contact between the Grubstake and Lignite Creek corresponds to an increase in sand percentage and a decrease in clay. Coals are thin and uncommon. The GR log shows sands individually 50-150' thick separated by clay-rich zones. Although the section is dominated by sand, these clay interbeds might provide some sealing capacity. Suntrana Formation Outcrop: The Suntrana Formation contains most of the coal at Healy and includes nearly all the thick and persistent coal beds. The Suntrana Formation thickens to the south and reaches a maximum thickness of 1290' along Healy Creek. The Suntrana is a many times repeated sequence fining-upwards of pebbly sandstone grading to medium and fine-grained sandstone (beds typically 20-100' thick)to clay and silt (beds 2-15') and coal at the top of the sequence. A single thick coal is typically present at the top of the sequence, but sometimes 2 or 3 thin coals are present. Overall, the formation averages 70%sandstone (including conglomerate), 15%claystone, and 15%coal. The sandstone is salt and pepper colored with dark-gray chert grains. It differs from the overlying multi- colored sands of the Lignite Creek Fm. Coal beds range from 10-60'thick and are laterally extensive. Nunivak#1: The Suntrana Formation in Nunivak#1 varies significantly from outcrops. The units is logged as about 80%sand, about 20%clay, and only a trace of coal. The GR curve shows a blocky sand about 900' thick lacking coal and clay beds. The 20%clay in the cutting samples may be in part cavings from uphole. The sandstone is predominately quartz and feldspar with 10-30% lithic grains. Conglomerate makes up about 5-20%of the lower part of the Suntrana. The Suntrana Formation as a • i thick blocky sandstone may be an excellent reservoir facies, but lacks internal seals. The overlying Grubstake and,to a lesser extent, the Lignite Creek may be a seal but this is not considered likely. Sanctuary Formation Outcrop: The Sanctuary Formation is a lacustrine unit which accumulated in a large shallow lake. The dominate lithology is gray shale which weathers to a chocolate brown or yellowish brown color in outcrop and is finely laminated (or varved) in beds up to an inch thick. The Sanctuary ranges from 5 to 350' in thickness depending on location. In outcrop it forms masses of brown to gray sticky mud, erodes to rounded subdued landscapes, and is prone to landslide. At the type section at the Suntrana Mine, the upper half of the Sanctuary is silty and contains numerous beds of fine sand from a few inches to a few feet in thickness. It is overlain by the sand-dominated Suntrana and underlain by a thick coal marking the top of the Healy Creek. Nunivak#1: The Sanctuary Formation in Nunivak#1 is predominately clay with a few sand beds. The lithology(mud) log indicates about 80%clay and claystone, about 15%sand, and about 5%coal. The sand is concentrated in 3 or 4 beds of about 10-20 ft in thickness which are more or less evenly distributed throughout the Sanctuary. The sand is described as fine-med grained and predominately quartz with less than 10% lithics. This sand could retain good reservoir quality in the subsurface and may be sealed by surrounding claystone. Micrite (limestone) is noted at 4 horizons in the Sanctuary Formation, attesting to a freshwater lake source. The most abundant micrite in cuttings was found near the top of the Sanctuary and might represent about 10-15 ft of limestone. The drill rate did not appreciably change in the micrite. Occasional coals scattered throughout the Sanctuary indicate very shallow or marshy conditions. The coals are generally associated with the sand beds. In Nunivak#1, C1-C4 gases were detected in the Sanctuary, yellow oil fluorescence occurred in clay, and coals were visibly degassing. Sandstones in the clay-rich Sanctuary are a primary target if they are charged with hydrocarbons. The GR curve confirms the clay-rich lithology with only occasional sands. The Sanctuary should be a good seal facies. Healy Creek Formation Outcrop: The Healy Creek Formation underlies the fine-grained Sanctuary and the top is marked in outcrop by a thick coal. At Healy,the Healy Creek Formation is widespread but patchy. It reaches a maximum thickness of 1,150' near Healy, but is about 2000'thick about 125 miles east at Jarvis Creek. Isolated and scattered coals throughout the Alaska Range and foothills probably correlate to the Healy Creek. The Healy Creek Formation consists of interbedded sandstone, conglomerate, claystone and coal. These lithologies are often mixed together and are not cleanly separated where seen in outcrop. Beds thicken and thin, sometimes abruptly, and grade laterally into other clastic lithologies. • The Healy Creek Formation appears to have gradually buried pre-existing topography,filling valleys first and covering hills later. Basement lithic fragments are common in the Healy Creek sandstones and conglomerates. Ridgway (1969) shows the Healy Creek Formation has more quartz than overlying units, probably reflecting the Yukon-Tanana source terrane to the north. Sands contain 80-90%quartz, 10- 20%feldspar,and few lithics. Nunivak#1: The Healy Creek Formation in Nunivak#1 contains about 50%clay, 10%siltstone, 30 sand, and 10%coal. Coal and sand is generally more abundant than in the overlying Sanctuary but the increase in coal and sand appears gradual on the lithogy(mud) log. Except for one trace indication (cavings?), micrite is absent from the Healy Creek in Nunivak#1. Sand is described as predominately quartz and feldspar with only a trace of lithics—a description similar to sand in the overlying Sanctuary. Sand beds appear to be 5-15'thick from the GR curve. Sands in the Healy Creek may be good reservoirs if sealed by surrounding claystone and charged with hydrocarbons. Late Paleocene Outcrop: It is uncertain if the expected Late Paleocene section is exposed in outcrop. The Late Paleocene is separated from the overlying Healy Creek by an unconformity spanning 31 m.y. (23.8-54.8 m.y.) based on palynology. In outcrop,the Late Paleocene portion of the Cantwell Formation is primarily volcanic and volcaniclastic rocks(Ridgway et al, 1999), but the Late Paleocene in Nunivak#1 is composed entirely of clastic sediments. Ridgway et al (1999) show a Lower Cantwell Formation of Late Cretaceous age that is conglomerate, sandstone, and shale, but these rocks are older than the expected Late Paleocene sediments in the well. The Paleocene section shown by Ridgway et al (1999) is entirely volcanic except for a basal conglomerate. Nunivak#1: The GR curve suggests the Late Paleocene in Nunivak#1 is dominated by clay and siltstone with sand beds comprising about 15%of the total section. The lithology(mud) log indicates about 50% sand throughout the Late Paleocene section and describes the sand as very fine to medium grained. Given the lack of downhole logs in Nunivak#1 due to hole problems, it is not certain why the discrepancy in sand content between the GR and the lithology log. Perhaps the sand has a high clay content and produces a higher GR signature than expected. Alternately, perhaps some of the clay washed through the shaker screens and is under-represented in the cuttings. Coal is common in the Late Paleocene and the lithology log shows coal comprises about 10-15%of the section. Some coal beds appear to be 10-15'thick. Carbonaceous claystone first appears about 500' below the top of the Late Paleocene and becomes common about 1000' below the top. Carbonaceous claystone was absent in the overlying Usibelli Group, except for two minor to trace occurrences in the Grubstake and Sanctuary, and in Nunivak#1 appears to be an indicator for the Late Paleocene. Like the overlying Sanctuary and Healy Creek, micrite (limestone) occurs at four horizons in the first 2000' of section. • • The lithology of the Late Paleocene does not vary significantly from the overlying Healy Creek. Abundant coal occurs in cuttings at the top Late Paleocene, but overlying Healy Creek rocks also contain coal, although in lesser amounts. Carbonaceous claystone, which first appears about 500' below the top Late Paleocene, seems to be mostly absent in the overlying formations. The GR highlights an attractive reservoir sand about 80'thick in the Late Paleocene about 1200' below the top. Sands like this may be good reservoirs if they retain porosity and permeability and are probably sealed by the surrounding clay-rich rocks. Based on the GR, sands are common in the first 2000' of Late Paleocene section and are nearly absent in the lower 1000'. Common metamorphic (schist) fragments, which occur in the bottom 1000' of Late Paleocene sediments in Nunivak#1 is probably an indication of nearby basement rocks.

After cementing casing and nippling up BOP Equipment, RIH to top of cement and pressure test the casing to the test pressure specified in the well plan (65% burst pressure = 34-00-psi/ 10-3/4" 45.5# L80 BTC)for 30 minutes and record on a chart(AOGCC required casing C 57 674) integrity test). The slowest possible pump rate is preferred to allow detection of leaks. Pump rates of 1/4 to 1 BPM are typical; however, adjust the pump rate to match the test pump capability to maintain a constant pump rate. Record pressures approximately every 1/4 bbl on the on the attached form. Plot the casing pressure test (volume versus pressure), and indicate how long the pressure is held on the casing. Verify that the test data forms a straight line and there is no air entrained in the mud, or leaks in the system. Repeat the casing pressure test if needed, especially if a straight line cannot be established at the higher test pressures. Note: It is acceptable to test the casing after bumping the plug following the primary cement job if the displacement went according to plan, the plug bumps at the appropriate strokes and the remaining cement pump time is adequate to allow completion of the pressure test. If the plug bump is not solid, i.e. a stable and continuous rise in pressure, then consider delaying the test to just prior to drilling out the shoe 2. Drill 20' to 50' of new hole below the casing shoe. 3. Circulate the hole to establish a uniform mud density throughout the system (required for a good downhole pressure test). Pick up into the shoe. 4. Close the blowout preventer(ram or annular). 5. Pump down the drill string at a rate approximating that used to test the casing in Step No. 1. Lower pump rates are preferred in order to minimize friction pressures losses (especially with long strings of small drillpipe)which are ignored in the calculations; however, adjust the pump rate to match the test pump capability and maintain a constant pump rate. Pump rates between 1/4 and 1-1/2 BPM are typical, with higher rates applicable to tests conducted with large intervals of open hole. 6. On the attached form, plot the fluid pumped (volume or strokes) vs. drill pipe pressure. Record pressures approximately every 1/4 bbl pumped. The data points should initially form a straight line with a similar slope to the casing integrity test as the system compressibility's are similar. Eventually, the formation begins to take fluid; at this point the pressure will continue to rise, but at a slower rate and the data points will deviate from the straight line. The first, sustained occurrence of this departure is the leak-of point(see Figure 1). Pump an additional 3 bbls after the suspected leak-off point is reached to assure continued decreasing slope on the pressure versus volume plot. If a straight line cannot be established during initial pumping (suggesting a surface leak or air in the system) or a clear leak-off point is not indicated, consider re-running the test. Be sure to bleed all pressure off the system prior to re-running the test. A slightly higher pump rate may be considered if a clear departure is not indicated on the pressure versus volume plot. Small filtration fluid losses can cause a slope change, especially at slow pump rates, and confuse the identification of a more definitive leak off point. • • Note: If a 12.7 ppg EMW or the maximum EMW specified in the wellplan is reached without indication of leak-off, shut down and hold the pressure there. This becomes the data for a formation integrity test (FIT) instead of a leak off test (LOT) 7. Shut down when the leak-off point is observed and 3 bbls of mud have been pumped into the formation. Record the instantaneous shut-in pressure (ISIP). With the pump shut down, monitor and record a 15 second and 30 second shut-in pressure and the shut-in pressures for a minimum of 10 minutes (at 30 second intervals) or until the shut -in pressure stabilizes. Plot the information and record the LOT point or FIT point on the PIT Form. Bleed the pressure off and record the fluid volume recovered if possibleNOTE: Pumping to the leak-off point plus 3 bbls is less critical for casing shoes other than surface casing, but it is important to pump enough to ensure a good LOT and not a spurious departure. 8. Corrective measures will be performed if the open hole pressure integrity fails to meet predetermined standards. The Drilling Engineer is to be notified immediately of any LOT or FIT that results in less than adequate formation integrity as defined in the Well Plan. Do not drill ahead until the inadequate formation integrity is addressed. i ;. -71 • i Nunivak#2 SGHA and Aquifer Review 6/12/2013 3601 C Street Suite 1424 Anchorage,AK 99503 907-272-1232(voice) 907-272-1344 Ilia) info@petroak.com ivww.petroak.conn To: Steve Davies, Sr. Petroleum Geologist AOGCC, Anchorage, Alaska From: Petrotechnical Resources Alaska (PRA) Date: June 12, 2013 Subject: Nunivak #2 Shallow Hazard Analysis and Aquifer Review Steve: I am responding to your request to PRA to present a shallow gas hazard analysis and for more information on the shallow aquifer beneath the Nunivak #2 well in the Nenana basin. This information impacts the request by PRA and Doyon Ltd. to conduct annular injection and disposal of drilling waste below surface casing at 2700' in the upcoming well. This email is a preliminary response and I will send a formal report next week. Since Nunivak #2 is scheduled to spud in mid-July, we hope to receive an expedited decision. In order to help the process, we would request a meeting later next week (Thursday pm or Friday, June 20 or 21) to present this information in support of the injection request. The data PRA has gathered indicates: 1. Subsurface water salinity is below 3000 ppm dissolved solids to a depth ✓ of approximately 3720' (-3330' Tvdss) in the Nunivak #1 well, which is the only deep well data in the Nenana basin. Salinities rise above 3000 Nunivak#2 SGHA and Aquifer Review Page 1 • Nunivak#2 SGHA and Aquifer Review 6/12/2013 ✓ ppm below 3720'. This is indicated by a salinity log analysis using the well logs from Nunivak #1. 2. Water bearing zones at the Nunivak location are described on water well logs as shallow as 94' in the Nenana Agricultural Project well (TD 193',no water analysis available) located about 1 mile NNW of the Nunivak #2 drilling location. Permafrost is estimated to occur to about 1800' at Nunivak #2 based on seismic data. 3. Water analysis from the water supply well (TD 340') at the Nunivak #2 location indicates total salinity of 200 but with elevated As (11.8 ppb) and Fe (3.61 ppm) above Maximum Contaminant Levels of 100 ppb and 0.3 ppm, respectively. 4. Except for the Nenana Agricultural Project well and the water supply well at Nunivak #2, all other water wells are associated near the town of Nenana and are located distant (-10 miles or more) from the Nunivak #2 drilling location. 5. Annular injection is requested for a volume of approximately 9000 barrels of waste. If injected into a vertical zone of 100' containing 30% porosity, the injected volume would displace formation fluids within a radius of 23' from the well bore. If injection occurred over 200' vertical, the injected radius would be 16'. 6. Review of Nunivak # 1 drilling results, and interpretation of seismic velocity and amplitude data shows no indication of shallow gas hazards. Attached are several files that support these conclusions. As noted above, an integrated report will follow next week.

PRA personnel reviewed the previous Nunivak#1 drilling hazards report, 2D seismic data, seismic velocity information, and offset well logs in completing the shallow hazard and pore pressure risk analysis of this well. Evaluation of this data shows no indications of drilling hazards or risks. The Nunivak#2 drilling engineer reports the drilling program for the Nunivak#2 will be similar to the plan successfully executed for the Nunivak#1. The Nunivak#2 drilling plan acknowledges the possibility of encountering shallow drilling hazards and incorporates processes to mitigate those risks while drilling. The logs and drilling data used for this analysis were taken from the Nunivak#1 well (Fig.1). PRA examined migrated time 2D seismic data and stacking velocities from the Doyon Nenana area 2D seismic data(Fig. 2). Permafrost, Gas Hydrates, Shallow Gas From an analysis of seismic stacking velocities,the base of permafrost was predicted to be at a depth of 1800' MD (+1- 150') in the Nunivak#1. The drilling engineer reported that the base of permafrost was encountered in the Nunivak#1 at approximately 2200' MD. Examination of the seismic stacking velocities near the proposed Nunivak#2 location suggest a shallower depth to the base of permafrost encountered in the Nunivak#1 well(Fig. 3). Nunivak#2 SGHA Page 1 • 1110 Nunivak#2 SGHA 5/31/2013 No reference to shallow gas or gas hydrates was cited by the well site geologist in their summary report for the Nunivak#1 well. On seismic line Wei-5004 (Fig. 4), the Nunivak#1 well penetrated several strong, continuous seismic amplitude events near the base of where the surface casing was set with no reported anomalous indications of gas or geopressure. The Nunivak#1 cuttings description listed interbedded sands and conglomerates characterizing the shallow section with evidence of thin coals below seismic detection limits. It is possible that at the Nunivak#1 location the shallow seismic data was of sufficient quality to image lithologic amplitude responses caused by interbedded shales, coals, or more continuous conglomerate layers. An examination of seismic line Wei-5005 (Fig. 5)tying the proposed Nunivak#2 location shows no consistent, anomalous amplitude events similar to what is observed at the Nunivak#1 location. The crossing strike line to the south of the Nunivak#2 location(Fig. 6) also shows no anomalous amplitude events in the shallow section to be tested by a well at the Nunivak#2 location. A multipanel 2D seismic traverse between the Nunivak#1 and Nunivak#2 locations (not shown) shows the shallow seismic data quality to be intermittent and poor. We do not / observe any continuous, strong amplitude events in the shallow seismic data at the proposed Nunivak#2 location. Faults The 2D seismic line Wei-5004(Fig.4)is oriented NW-SE through the Nunivak#1 location and the 2D seismic line Wei-5005 (Fig. 5) is oriented NW-SE through the Nunivak#2 location.No faults are observed in the shallow section of seismic line Wei-5004 and no drilling losses attributed to faulting were encountered according to the Nunivak#1 drilling report. No faults are / interpreted in the shallow section of seismic line Wei-5005. A comparison of these two seismic lines offers further confidence that no shallow faults visible on seismic should be encountered in the proposed Nunivak#2 wellbore. Pressure The nearest well data, the Nunivak#1, and the seismic stacking velocities at the Nunivak#2 location indicate that the Nunivak#2 well will penetrate a normally pressurized section in the first 3000 feet. Two (2) seismic velocity functions were extracted at the Nunivak#2 well location. The Nunivak#1 sonic log data displays a tenuous correlation with these extracted Nunivak#2 seismic velocities converted to Interval Travel Time(ITT) (Fig. 7). ITTs calculated from the two Nunivak#2 area seismic interval velocity functions result in more detail than the seismic average velocities and render reasonable agreement to the Nunivak#1 sonic data from below surface casing/base permafrost to just above the Sanctuary interval (Fig. 8).

By comparison the Nunivak#1 seismic interval velocity ITT did not yield a good match to the Nunivak#1 shallow or deep sonic ITT trend but matched well from base of permafrost to the Suntrana formation(Fig. 9). Mud log and sonic log data from Nunivak#1 indicate that the well was normally pressured beginning with a mud weight of 9.1 ppg and ending with a mud weight of 9.7 ppg at TD (Fig. 10). The Nunivak#1 V,., seismic velocity data(Fig.9)also supports a normal pressure gradient in this well although there is a mismatch with the sonic data in the permafrost section. No anomalous velocity inversions are observed on the Nunivak#2 V,,,,s(Fig. 8) seismic velocity functions that might indicate possible geopressure. The drilling engineer stated his intention to incorporate a similar mud weight discipline in the Nunivak#2 drilling plan. The overall assessment is that the proposed Nunivak#2 well should V encounter normal geopressure similar to the Nunivak#1. Nunivak#2 SGHA Page 3 • r .

Will also need a detailed procedure for your proposed LOT for the shoe and the follow-up LOT for the AD qualification. I did not see where you were doing the follow-up LOT after drilling was completed. (sundry required for AD disposal I may have a few more questions later... I know we are also waiting on the shallow hazard assessment.

Could PRA/Doyon please provide a legible copy(electronic or printed) of the poster presentation titled "Formation Characteristics, Nenana Basin, Alaska"? The copy supplied with the application is too small. Regarding Regulation 20 AAC 25.061,Well site surveys: The information supplied by PRA to date is not sufficient to satisfy the requirements of this regulation. The well that is nearest to the proposed Nunivak 2 location is 7 miles distant. How extensive is the seismic coverage in this area? What is the quality of the seismic data? Has the exploration geoscientist seen any evidence of shallow gas or geopressure on the seismic data in the vicinity of the proposed well? Could PRA/Doyon please provide AOGCC (or come over an show me)copies of the seismic shotpoint basemap and the shallow portions of seismic lines for this prospect?

Mud in pits and ready to spud well. 07/12/2013 Spud well at 1900 hours. Conditioned mud and drilled out cement in conductor casing. Gas system was calibrated by mudloggers (07/12/2013). Gas: Max gas was 2 units and the Average gas is 1 unit Geology: Cuttings has been predominantly sand. Samples are medium to coarse grained and unconsolidated. 07/13/2013 Drill from 210' MD to 1660' MD without issues. Routine inspection of gas system was conducted and observed okay. Gas: Max gas was 6 units at 257’ MD and the average gas was 2 units Geology: Cuttings has been predominantly sand with abundance of gravel noticed at 1280' MD to 1520' MD. Traces of chert were observed from 1230' MD to 1610' MD also were traces of coal and lignite. 07/14/2013 Drilled to TD (surface hole section) 2710' MD at 12:06 PM without issues. Did a hole-cleaning sweep with 280 viscous AQUAGEL, pumped a dry job and pulled out of hole to the top of the BHA (wiper trip). Return to bottom with no problem. Swept hole the second time with 105 viscosity, pumped a dry job, pulled out of hole to lay down BHA and pick up 10.75" casing. Conducted a bagged gas test of gas equipment and got a good result. 30' dry and 60' wet samples collected to 2710' MD, logged and packaged. Gas: Max gas was 5 units at 1390’ MD and the average gas was 2 units Geology: Cuttings has been a mixture of sand and gravel with the sand finer towards TD. Occasional woody plant remains and coal trace were also observed. 07/15/2013 Pulled drill string out of hole and lay down BHA. Rigged up and ran 10.75" casing into hole to 2677' MD. Lost 30 bbls of mud while running casing due to the gel strength of mud which was forced into sand and gravel beds. Gas: Max gas is 0 units and average gas is 0 units Geology: No geologic samples collected 07/16/2013 Ran 10.75" casing without issues and pumped cement, obtain full returns while circulating but saw no spacer or cement. Rigged up and opened 2nd stage tool 302' MD below ground. Circulate cement and mud out of upper annulus. Pumped 2nd cement job which yielded full returns. Reserved approximately 300 bbls of mud in pits for drill out. Gas: Max gas is 0 units and average gas is 0 units Geology: No geologic sample collected 07/17/2013 Made up 350 bbls of new 6% KCl/Polymer mud while keeping spud mud for drill out. Rigged down diverter system, and riser and flow line. Begin installing new BOP system. Gas: Max gas is 0 units and average gas is 0 units Geology: No geologic samples collected 07/18/2013 Completed making 350 bbls of KCl/Polymer mud (LSND, 8 bbls/baro-trol), nipple up of BOP system and calibration of Gas chromatograph (model 8900). Picking up of drill pipe and hanging stands in the derrick for drilling next section. BOP test will not be witnessed by AOGCC. Gas: Max gas is 0 units and average gas is 0 units Geology: No geologic samples collected 07/19/2013 Treat Spud mud for drilling out cement. Add ALDACIDE G to old and new muds in pits to keep bacteria in check. Have issues with testing of BOP system. Began making up 5" drill pipe stands and placing them in the derrick. Drilled cuttings are being hauled for disposal at the local landfill. Gas: Max gas is 0 units and average gas is 0 units Geology: No geologic samples collected 07/20/2013 55 bbls of Spud mud moved to Tank farm to allow for drill pipe displacement when going into hole. Tested BOP system (received BOP part from Deadhorse which was delayed by weather). Pick up BHA Assembly to drill out ES cementer. Gas: Max gas is 0 units and average gas is 0 units Geology: No geologic samples collected 07/21/2013 Drill out the stage Tool at 302' with a PDC bit (gas released as a result of burning rubber on second stage cementer). 5' drill pipe stands built and placed in the derrick. Tripped into hole and tested casing to 3000 psi and picking up 11500' of 5" drill pipe, then drill out cement. Gas analyzer was calibrated. Gas: Max gas is 511 units and average gas is 0 units Geology: No geologic samples collected 07/22/2013 Making up stands of 5" drill pipe and racking them in the derrick completed. Drill out the float equipment and cement (top of cement at 2617' MD) in the casing plus 20' (2710' MD to 2730' MD) of open hole. Pumped a 25 bbls Hi-Vi BARAZAN D PLUS spacer between the spud and KCl/Polymer muds. Displace old mud in the hole with new mud. 11 units of recycled gas was noted which is from the burnt rubber plug. Gas: Max gas is 11 units and average gas is 8 units Geology: Sample collected is predominantly cement with ground up rubber from the plug from 302' MD. Lithic fragments and mica also observed in the sample. 07/23/2013 Performed Leak-Off Test to 12.7 ppg EMW at 2730' MD with 9.0 ppg KCl/Polymer mud. Dumped old mud and cleaned pits made 600 bbls of new mud. Laid down "Dumb Iron" drill-out assembly pick up drill-ahead BHA and inspected gas equipment okay. 07/24/2013 New smart iron BHA #300 tripped into hole and drilled.

An 8” SperryDrill motor set at 0.78° was utilized for corrective steering to maintain a vertical hole. The assembly began to build inclination at ~0.3° per 100’ after drilling through the base of the permafrost at 1700’. The assembly built to 1.55°by 2116’ MD before a corrective slide was made which dropped the inclination to 0.69°. The assembly continued to build to 1.73° at 2499° where another corrective slide was made. The final inclination surveyed in the surface hole was 0.67° at 2639’ after drilling to the section TD of 2710’. The assembly was tripped out and 10-3/4” casing was ran to 2700’ MD. 9-7/8" production hole: The vertical production hole was drilled from 2710’ to 8623’ MD. A rotary assembly with a PDC bit was utilized to drill out the 10-3/4” casing shoe and 20’ of new hole. A 7” SperryDrill motor set at 1.22° AKO for correct oriented drilling was utilized to continue drilling the vertical hole. A 2° max inclination and 100’ radius target area was given for wellbore restraints. Three bits were utilized to drill the section to 8623’ where TD was called early for geological reasons. The assembly was tripped out to set a cement plug and sidetrack the well. 9 7/8" production hole: Nunivak #2 was sidetracked at 2730' and drilled to 10912'. The sidetrack was accomplished with a GP7600 EDL. After drilling 1488' the Geo-Pilot assembly was pulled out for slow ROP. A 7" SperryDrill motor set at 1.5° was utilized to finish the build section. The remaining tangent section was drilled in three runs. The first run was with GP7600 EDL full service to 10912'. The second run was with GP7600 EDL quad combo string to 10912'. The third run was with a 7" SperryDrill motor set at 1.22°. The string got stuck in the hole during trip in. Drill string was severed at 8586'MD and the BHA was lost in the hole. A 10-5/8" casing was run to 8374'. 6 3/4" production hole: Nunivak #2-ST was sidetracked at 8390' and drilled to 11816'. The sidetrack was accomplished with a 5' SperrDrill 6/7 lobe 6 stage motor. After pulling out of the hole to test BOPs, the same assembly was used to drill to 12396' where it got stuck. Retrieval attempts were unsuccessful. BHA SUMMARY BHA #1: An 8” SperryDrill motor set at 0.78° AKO was ran with a 13-1/2” Halliburton mill tooth bit to drill the surface hole section from 100’ to 2710’ MD. The logging tools consisted of Sperry directional, gamma and resistivity. The assembly was rotated down to the base of the permafrost at 1700’ where the assembly began to build at a rate of 0.3° per 100’. After building to 1.55° at 2116’, a 46’ corrective slide was made which dropped the inclination 0.69°. The assembly continued to build in rotary mode to 1.73° at 2499’ and a 66’ slide was made to drop the inclination to 0.67°. The TD of the surface hole was called at 2710’ MD. The hole was circulated clean and the assembly tripped out without difficulty. The BHA was laid down without incident and the rig began to run 10-3/4” casing. BHA #2: A rotary assembly with a 9-7/8” Halliburton SF56PDC bit was utilized to drillout the 10-3/4” casing. The assembly was tripped in to the 2nd stage cement collar. The stage collar was drilled in 9 hours and the aluminum and rubber were circulated out before continue tripping in the hole. The top of cement was tagged at 2617’ and the casing was pressure tested to 3000 psi. The rig picked up 72 stands of drillpipe and racked it back in the derrick before drilling out the cement track. The shoe track was drilled in 5 hours and 20’ of new hole was drilled in 8 minutes. The hole was circulated clean and then displaced with 9.0 ppg LSND mud before performing a leak-off test to 12.7 ppg EMW. The assembly was tripped out to pick up a motor and logging assembly. Job No: AK-XX-0900525671 Well Name: Nunivak 2-ST End of Well Report Page 1 of 10 BHA SUMMARY BHA #3: A 7” SperryDrill motor set at 1.22° AKO was utilized with a 9-7/8” Halliburton SF56 PDC bit re-ran from BHA #2. Sperry MWD logging tools consisted of real-time directional, gamma ray, resistivity, azimuthal density, neutron porosity, pressure while drilling and recorded sonic. Drilling began with 80 RPM and 500 GPM and the assembly was holding an average of 0.50° inclination at an average azimuth of 55°. Despite the low inclination, the wellbore was still walking away for the origin about 1’ per 100’. The ROP averaged 151’ per hour down to 3741’ with an average WOB of 4K. From 3741’ the ROP began to slow down to 104’ per hour. At 3767’ the wellbore was 33.5’ away in a 55° direction from the origin and a corrective slide was made to steer back. The direction was turned to a 200° azimuth and the wellbore began walking back. At 5267’, a swab went out on the mud pump and drilling continued with 333’ gpm with reduced WOB. During repairs of the mud pump, it was found that the fluid end was cracked and no replacement was on location. The decision was made to stop drilling at 5554’ and trip out to test BOP equipment. The bit was found to have severe cutter damage and rung out from suspected ½” diameter pebbles of chert while drilling conglomerates. BHA #4: The same mud motor from BHA #3 was run again with a new replacement SF56 PDC bit. The assembly was tripped in and the last stand washed down. The new bit was broken in with light weight on bit and averaged 132’ per hour from 5554’ to 6795’. At 6244’ the inclination began to build and was 1.39° at 6725’. A 25’ slide was made which dropped to 1.13° inclination. The assembly continued to build in rotary mode and built to 1.77° at 7105’. A short trip was performed with multiple tight spots which were wiped then pulled clean. No problems on the trip in. A 25’ slide was made which dropped the inclination to 1.26°, but built up to 1.34° while rotating. Continued to slide to drop the assembly, but the formation was hanging up the assembly and ROP was slow. The remainder of the stand was rotated down at 17’ per hour ROP and the inclination built up to 3.37°. 5’ was slide on the next stand at 7’ an hour ROP before the decision was made to trip and inspect the bit. The hole was circulated clean and the assembly was tripped out with only two overpulls at 4630’ and 4530’. The bit was found to be worn and 1/16” undergauge, but not severe enough damage to cause such a slow ROP. BHA #5: A new 7” SperryDrill mud motor was picked up as a precautionary measure anticipating a long drilling run and the AKO was increased from 1.22° to 1.5° setting. A new 9-7/8” Halliburton FX65 PDC bit was ran. The 6-blade 5/8” cutter design should perform better in the harder drilling. A new MWD pulser and XBAT tool were also picked up to allow for a week of service interval on these tools. MWD logging sensors consisted of real-time directional, gamma ray, resistivity, azimuthal density, neutron porosity, pressure while drilling and recorded sonic. The assembly was tripped to 2720’, placing the bit outside the casing shoe and the mud was conditioned while cutting and slipping drilling line. The trip was resumed and a tight hole was encountered from 4500’ to 4800’ which was reamed through. The remainder of the trip was made without difficulty. Drilling resumed with a 30’ slide before it hung up and the remainder of the stand rotated down. The survey showed a 4.52° inclination. A 50’ slide was made which dropped the inclination to 3.78°. This placed the wellbore 44’ away from the origin, so another 50’ slide was made to 8465’ which continued to drop the inclination to 3.03°. Another slide was attempted but hung up after 17’ and could not be continued. The next survey showed the inclination built 3.13° so further slide was necessary. 5’ of slide was made at a 2’ per hour with very little differential pressure observed. Parameters where varied, but nothing improved drilling. The slide was abandoned and began rotating with 5K WOB to keep the assembly from building with an ROP average of 6’ per hour. At 8611’ the company man called and instructed us to rotated attempting to get the best possible ROP regardless of directional needs. The WOB was increased to 12K and the ROP increased to 9’ per hour. At 8625’ the decision was made to TD the well early. A sweep was pumped and the hole circulated clean before tipping out of the hole. The TD of Nunivak #2 was reached at 8625’ MD / 8623’ TVD. BHA #6: Made up BHA #6 and during the confidence test, a low g-total of the DM was observed. The DM was laid down and replaced with the backup tool. The tools were confidence tested again, initialized and pulsed tested before tripping in the hole. The assembly was tripped in to 2251' and washed down with 100 gpm. No cement was observed by the casing shoe at 2700', so a bottoms up was circulated at 200 gpm. No cement was observed. The rig waited on cement another 8 hours. The MWD tools and GeoPilot were function tested with 450 gpm. Good detection and downlinks were achieved, but the GeoPilot experienced high g-totals while rotating and would not deflect. With only 0.66° observed at the GeoPilot, it was suspected that the housing was rolling in the casing and possible high friction from cement contamination causing the high g-total. After waiting another 8 hours on cement, tripped in the hole and tagged cement at 2700'. Weight was set to 5k then increased to 15K. Ratty cement was drilled to 2722' where it firmed up. Cement was dressed to 2730'. After making connection the sidetrack was initiated with the following parameters, 450 gpm, 5 WOB, 60 rpm, 100% deflection, 0° TF. ABI started trending up at 2745'. Deflection was reduced to 80% after 50'. At kelly down 2826', ABI was 5.20°. The survey inclination was 4.08° and azimuth 203.81°. After the successful sidetrack, the well bore was gradually turned to planned azimuth with next stand drilled with 60% @ 60L TF. At kelly down 2922', Inc was 7.02°, Azimuth 180°. The assembly was then pulled into the shoe for mud . Drilling resumed with -70L TF to turn azimuth around and build inclination slowly at the same time. After turning azimuth to 112°, the deflection was maintained at 55%, 10L TF to continue with the build. Flow was increased from 550 gpm to 580 gpm. A hard stringer was encountered @ 3826'. There was housing roll @ 3910' which lasted around 25’. The ABI dropped 0.60°. The rotary was dropped down from 120 rpm to 60 rpm and flow from 580 gpm to 550 gpm to help reduce the washing around the cutters to eliminate the housing roll. Drilling started getting ratty around 3967’. The rig floor was rattling at 120 rpm and very light weight. RPM was reduced to 60 rpm. While trying to build with 70% deflection at 4030' there were indications of hanging up. A “Home” command was downlinked. ROP gradually increased to 110 fph. After drilling 7', the deflection was increased to 60% and HS to continue with build. At 4060', a very hard formation was encountered. RPM was reduced and weight on bit gradually increased to improve ROP. ROP avg for the stand drilled down was 16 fph. There was no build while drilling through these hard spots. There was housing roll at 4135'. Flow was reduced to 550 gpm to counter the problem. The ratty drilling continued while drilling through hard stringers with 80 rpm. At 4173’, Dril N Slide and EZ Glide lubes (3/10%) were introduced into the mud system to prevent contaminating cuttings. Formation between 4217’ – 4218’ was drilled with over 1.5 hours with 22k – 25k WOB. Samples showed cemented sands and siltstones. A hi-vis sweep was pumped. After monitoring the well and pumping dry job, the assembly was pulled out for penetration rate. There was 10 – 20K over pull between 3800’ – 3600’. The bit was graded 3-4-BT-A-X-I-CT-PR. Drilled 1488’ with 19.95 bit hours for an average of 75 fph. BHA #7: BHA # 7 was made up and tripped in the hole. The last stand was washed down to bottom. A 30’ slide was done to continue with the Job No: AK-XX-0900525671 Well Name: Nunivak 2-ST End of Well Report Page 2 of 10 BHA SUMMARY build. The formation was very soft during the first slide interval which resulted in a 5.5° motor output. The parameters used were 12k wob, 550 gpm, and 100 psi differential pressure. The assembly also showed a drop and right hand turn tendency during the first two stands of rotary. The slide intervals were increased to 55’ to counter the soft formation and also the rotary drop tendency. At 4473', the formation started hardening while sliding with 15k wob, 550 gpm, 150 differential pressure, 65 fph rate of penetration. Motor output on the next slide gave 6.8°. The slide intervals were cut down to 35' while continuing with the build to 56°. After finishing the build, the sail angle for the tangent was held at 59° to catch up with plan after discussion with Onsite geologist and Company representative. Once 59° inclination was achieved maintenance slides were performed every two stands. At 5623’ the rate of penetration dropped down to 20 fph with erratic torque. The mud log samples showed clay. A 30 ppb nut plug sweep was pumped which helped in unballing the bit. ROP increased back to 80 fph after the sweep was pumped. Maintenance slides of 20 – 25’ were performed as needed to keep borehole above well plan. The top of the Suntrana formation was called by the geologist at 6848’ MD. The hole took 20 bbls. At 7064' a pressure spike was observed. The concern was it was a cone dragging. After drilling to 7125’ MD, decision was made to pull out of the hole due to pressure spike and pick up the GP7600 EDL rotary steerable system and condition mud on the trip. Pumped sweep around and five stand were pulled on elevators. Assembly pulled smooth and a dry job was pumped. At 6699’ attempted to pull on elevators however 40K overpull was observed. Washed up to 6587' then attempted to pull without pumps to 6524' but observed 40K overpull. Backreamed out from 6524' - 5782'. Attempted to POOH with pumps only to 5507'. Assembly was trying to pack off while pulling 35k over. Continued backreaming out of hole from 5507' - 4075'. A bottoms up was circulated and lot of clay was observed over the shakers. s. Attempted to pull on elevators from 4075' - 4024'. Assembly pulled 30-40K over. Continued backreaming out of hole from 4024' - 2922'. Two bottoms up were circulated. The assembly was pulled out on elevators from the shoe. HWDP/Jars were racked back, the MWD tools were read and the BHA laid down. The bit graded 6-7-CI-N-F-4-BT-BHA. Drill 2907’ with 40.76 bit hours for an average of 71 fph 557’ was oriented with 7.45 bit hours for an average of 77 fph 2350’ was rotated with 33.31 bit hours for an average of 71 fph BHA #8: BHA #8 was made up and tripped in the hole to the shoe where the drill line was cut and slipped. The mud was circulated and conditioned at the same time. Drilling was started with 575 gpm and 150 rpm. The GeoPilot initially showed a drop and right hand walk in neutral. Lubes were introduced at 7500’and the percentage was increased to 2% as drilling continued. The borehole was being maintained 3-5’ above well plan. The on bottom drilling torque and ECDs kept trending up as drilling continued. A short trip was performed at 8645’. The assembly was pulled out on elevators to 8223’ where 25k over pull was encountered. Assembly was backreamed to 7020’ where a weighted sweep was pumped around. The assembly was tripped in to 8445’ where 20k drag was noticed. The assembly was reamed down to bottom and drilling was resumed. The on bottom torque kept increasing and was around 15 – 17k-fp at 9402’. The Coman decided to circulate a bottoms up at this point to help lower the ECDs. The circulation did not help in reducing the ECDs. Drilling continued to 10071’ where on Kelly down 25k increase in up weight and 12k additional slack off was observed. Decision was made to short trip one stand early. A bottoms up was circulated. Due to the high ECDs and torque, the assembly was backreamed out of the hole. The short trip decision was then changed to pull out of hole for BOP tests. Backreaming continued to the shoe after which the assembly was pulled out on elevators. The BHA was racked back. The bit was graded 1-1- ER-N-X-I-NO-BHA. The hard spots encountered during this run where drilled by reducing the rotary to 70 rpm and gradually increasing weight to 22k. The GeoPilot held inclination with a 25% deflection throughout the tangent section. Drilled 2946’ in 26.61 bit hours for an average rate of penetration of 111 fph. BHA# 9 : ade up BHA #9 and tripped in the hole to the shoe at 2700’ where the first mud displacement was made. Continued tripping in the hole on elevators to 8760' where string took 50K weight. After slow progress down to 8900' decision was made to displace again to new mud. To continue with displacing mud the BHA was reamed down to bottom. The hole packed off at 9542' in a coal bed interval. Coal drilling procedure was followed and the BHA was reamed down to bottom to commence drilling. Once on bottom drilling commenced with 120 rpm, 550 gpm, 8k WOB. Toolface was set at 10L with 20% deflection during the stand. This maintained the inclination but the azimuth turned right at 1.64° /100’ indicating a strong right hand walk and drop tendency. After 42’ at 70L @ 24% deflection to get the azimuth over from 118.32° to 116.87° a tool face an average tool face of 20L with 33% deflection to maintain the 116 azimuth and bring the inclination up from 56.27° to 57.79°.The on drilling torque was around 20k-fp with high stick slip. The rotary was increased from 120 rpm to 150 rpm which reduced the stick slip but drilling torque remained high. Nut plug sweeps were pumped at 10169' and 10215' to help clean the hole and reduce torque. At 10337' the string torqued up and almost stalled the top drive. The string was picked string up 30' to let cuttings move up and also reduce the torque. Another nut plug sweep was pumped at 10337'. Since the top drive had started stalling more often due to high torque, the drilling torque limit was increased to 21.5k-fp at 10441’ and rotary down to 120 rpm to help maintain a consistent 75 fph penetration rate. At 10829’, the rotary was further reduced to 100 rpm to help reduce stalling the top drive. The drilling parameters were 100 rpm, 8-10k WOB, 21k-fp torque, 600 gpm. Coal seams were drilled at 10237’-10267’MD, 10276’-10281’MD,10346’-10356’MD,10385’-10395’MD,10435’-10442’MD,10506’10519’MD, 10569’-10580’MD,10608’-10620’MD. When drilling through the coals the top drive would struggle and almost stall, this happened a lot throughout the run. At 10912’ it was decided to pull out of the hole for high torque. After circulating out sweep, back reaming was commenced to chase cuttings and clean the hole. While back reaming out of the hole the assembly experienced a high amount of stick slip along with multiple packs offs that correlated with coal seams on the log. A sweep was pumped at the casing shoe. After the sweep was seen at surface the assembly was pulled on elevators without incident. No visible damage was seen on the tools at surface. The bit graded 1-1-PN-N-X-I-NO-TQ. Drilled 841’ in 14.18 bit hours for an average rate of penetration of 59.30 fph. BHA # 10 was made up and tripped in the hole. Shallow pulse test could not be performed due to rig pump problems. The BHA was tripped in with the rest of the HWDP and 30 joints of drill pipe from pipe shed. Shallow pulse test was attempted which was good. After tripping to the shoe, the drilling line was cut and slipped. The BHA was tripped in on elevators with pipe filled every 1500’. The drag was around 15-20k during the trip in. A tight spot at 6870’ was worked by orienting the string ¾” turn. Further tight spots were encountered at 8867', 9360' and 9570'. The trip in Job No: AK-XX-0900525671 Well Name: Nunivak 2-ST End of Well Report Page 3 of 10 BHA SUMMARY was continued to 9715' where the string started to take 35k over and hold. The top drive was made up and oriented to work string through tight spot with no success. The Company representative was informed about reaming through tight spot. With rotary at 20 rpm and 200 gpm reaming was commenced when the rotary stalled. The rotary was increased to 50 rpm. Stand pressure was holding 1500 psi indicating pack off with returns at 10%. Decision was made to back ream above coal seams. String was back reamed from 9715’ to 9439’ with 50 gpm, 1500 psi and 5%-10% returns. At 9439', the rotary stalled and the string could not be worked up or down. Attempt to fire jars failed and work was continued to get pipe free with no success while waiting on fishing tools. Old mud from tank farm was transferred to the active pits and circulated due to downhole losses. Returns were established and pumps were staged up slowly to 510 gpm at 1550 psi. The rig was able to fire the jars in both directions but with no success in freeing the string. Drill string was severed at 8586’MD. BHA was lost in hole. BHA #15: SDS Run 1100 was made up and run in the hole. The company rep decided to add 14 extra joints of HWDP to the 16 planned for our BHA for a total of 30 joints. Cement was tagged up on in casing at 8019’. Hard cement was drilled 8019' to 8390'. A conference call was made with the Drilling Engineer and it was decided to start time drilling from 10' below the shoe. As soon as the assembly got out of the shoe at 8380', there was no cement, It started firming up again from 8387’; It was decided to start time drilling as planned from 8390'. Time drilled from 8390' to 8392' @ 5min/inch, from 8392' to 8394' @ 4min/inch, from 8394' to 8407' @ 3mins/inch –holding a 70L TF 275GPM 2300PSI, not seeing any changes in WOB or seeing any differential pressure, at this point there was no formation in the cuttings it has been 100% cement. At 8407' stopped time drilling and pulled back into the shoe so Halliburton Cementer's could rig up and perform a LOT. An equivalent mud weight of 11.65 was achieved from the leak off test. The assembly was tripped back in the hole to 8407', where it was decided that it might be easier to side track using a 130L tool face. Time drilling was continued at a 130L tool face at 3min/inch. SDL reported to Sperry DD that the cuttings sample at 8410' showed that the cement was getting softer. The next cuttings sample at 8413' showed that the cement was firmer but still not hard. Cuttings samples had been 100% cement up to this point. The first clean survey at 8402' showed a 2° change in azimuth. At 8429’ the decision was made to quit time drilling and begin control drilling at 10'hr. A cuttings sample at 8470' show a 30% concentration of formation, samples were taken every 5'MD, with the concentration building up each sample to 90% @ 8510"MD. Control drilling was continued at 10'/hr. to 8537'. Circulate bottoms up where the geologist confirmed formation percentage was at 90 % and that the assembly successfully side tracked from the old well bore. The next two stands were rotated down. Magnetic interference was experienced on the first two surveys due to the fish. On the next three stands, three slides of 32' were performed to bring the inclination back up and turn the well left. The inclination was brought up to 59.4° so the next three stands were rotated. In rotary the assembly was dropping 0.30° and walking right 0.50°. Slight Stick slip and vibration was experienced during the back reams. 50RPM seemed to work the best during the back reaming. On the next stand the BHA dropped 0.36° and turned 0.56° to the left. So a slide was put in at 30R to counter the drop and turn. On the next stand the BHA built 0.05° and turned 0.68° to the right. After rotating another stand down the BHA built up 59.21 and turned to the left again 0.31°. So a slide at 120R performed to counter the build and left hand turn. The next stand down survey at 9752' showed assembly is dropping 0.11° and turning left 0.23° in rotary. A slide @ 70R was performed. With the BHA wanting to walk left, the plan of rotating ahead and letting it walk right was not going to work, start putting 30' slides every stand to turn the well right due to falling behind on the turn. AT 10100' the drilling slowed down and sliding became difficult. A slide of 9' was performed and then rotated 5' to get out of the hard formation. Slide another 4' with the same results, rotate 6 more feet and attempt to slide again with no success, due to the motor stalling. Rotated to 10177' circulated a bottoms up and performed a wiper trip to shoe. The first three stands of the wiper trip pulled with no issue, pumping was required on the next two stands, after that reaming was required all the way back to the shoe. Once in casing a sweep was pumped and a bottoms up was circulated. The trip back to bottom went good no tight spots on the way in. Wash last stand down. While lining up to slide the massive amounts of coal started to come over the shakers. The pipe was worked while circulating; it took 45 min for the shakers to clean up. Sliding had become very difficult due to the formation the mud motor would stall easily when put on bottom. Rotated ahead to get into better formation. Managed to put in 2 and a half good slides, turning the well to 120.56° and started having problems again. Had a discussion with the Drilling engineer Mike Cook at 10560' who said to rotate the next 1000' keeping the inclination between 50° to 55°+ and the Azimuth between 120° to 125°+. Correction Slides will be made if the assembly goes outside this window. After drilling down to 10949', while making up the new stand the stump connection got galled while screwing into it. The pipe sat without movement for 30 minutes while trying to rack back the stand that was just picked up. After racking back the stand the driller latched up the elevators to move the drill string, pulled 40k over without breaking over and the jars didn’t fire. A head pin was screwed into the stump and pumped through the cement line to get flow. Worked stuck pipe, pulled 80k over got the jars to fire and the string came free. The top joint of stand 102 was laid down and stand 103 was racked back due to a galled pin connection. Picked up stand 104 it became stand 103 drilled it down. A single from the pipe shed was picked up to replace the galled one laid down from stand 102. From 10949 drilling parameters were varied to control the left hand turn tendency of the BHA. AT 70 RPM 6K WOB the assembly dropped 0.41° and turned 0.07° right. At 80RPM 6K WOB the assembly dropped 0.40° and turned 0.04° right. For the time being the RPM’s were kept at 80 due to the better hole cleaning and ROP. At 11528' a sweep was and the hole was circulated clean, after that sweeps were pumped every stand, started getting back loads of coal at the shakers. Reducing to 70 RPM’s with 6/7 WOB helped to decrease the rate of drop in inclination and get a slight right hand walk, enabling us to rotate ahead longer and still stay in the window given by Mike Cook. A survey at 11584' showed that the assembly had built 0.50° and walked left 0.45°. The hole was drilled down to 11816', it was circulated clean and the decision was made to POOH for BOP test. POOH on elevators from 11720' to 11624', after that 25K over pull was observed so back reaming out of the hole was commenced. The assembly started torqueing up and packing off @ 9620' went back down and lowered the flow to get returns back, slowly brought the flow back up and worked up slowly through two large coal seams to 9582'MD and again at 9060'MD the assembly attempted to pack off again, so reduced pump rate and worked pipe to establish full returns, experienced full stall stick slip but was able to work thorough the coal seam. The rest of the trip back to the shoe went good. A sweep and a dry job were pumped at the shoe. None to slight vibration was observed during drilling, short events of high stick slip and full stall were observed during some of the back reaming. No visible damage was seen on the tools at surface. The bit graded 0-1-CT-G-X-I-HC-BOP. Not including the time or footage to side track the assembly drilled 3280’ in 39.97 bit hours for an average rate of penetration of 82 fph. Slide footage was 412’ and accounted for 13% of the footage drilled and 29% of the drilling time at 11.44 hours for an average rate of penetration of 36 fph. Rotary footage was 2868’ accounting for 87% of the footage drilled and 81% of the drilling time at 28.53 hours for an average rate of penetration of 100 fph.

Circulate and pull out to pick up remainder of BHA. Resumed drilling to 665' with no problems and picked up a stand of DP to drill to 757'. Racked back stand of DP and picked up accelerator and 2 joints of HWDP. On the first joint of HWDP above the accelerators the rabbit got stuck and the HWDP joint had to be swapped out. Finished picking up that last bit of BHA and resumed drilling. At 809' the joystick was not fully engaged for drilling, thus a false drop in ROP values occurred. The next stand from 854' to 950' was control drilled to have time to condition the mud (low vis). Resume drilling at a controlled rate of 65 fph to keep mud properties consistent. Drill down to 1,225' and start gradually increase ROP while monitoring mud properties closely. At 1,425' bring flow rate from 450 gpm to 500 gpm and rotary from 60 rpm to 80 rpm with a bit weight increase from 5k to 6k-8k. At 1,620' increase flow rate to 550 gpm. One additional flow increase from 550 gpm to 575 gpm was performed at 1903’. As the drilling assembly got below the PermaFrost (`1700') the inclination started a slight build trend of +0.3°/100. While orienting for the slide at 2572' the top drive brake didn't hold the adjustment, resulting in a re-orientation before sliding. Finish drilling to surface casing point at 2700' with no problems. Circulate hole clean and short trip to the drilling jars and back to bottom. Short trip went well with no instance of tight spots. When back to bottom drilled an additional 10’ for casing tally. Drill 2610’ with 27.24 drilling hours for an average of 96 fph. 112' or 4% was oriented with 1.23 drilling hours for an average of 91 fph. 2498' or 96% was rotated with 26.01 drilling hours for an average of 96 fph.

After all the 5" DP is picked it it will be used to drill the shoe track and 20' off new hole, where the hole will be displaced to new mud and a LOT done. RESULTS The BHA was made up and run in to tag the stage equipment at 301’. Start drilling out the stage collar at 301’ with limited success. Alter the flow rates and rpm's with no additional progress noted. Shut down pump and tried scoring the plug with no success. Started adding weight up to 20K WOB with some minor progress, but wouldn't drill off any weight. Ended up going to 25K WOB and it would start drilling off down to 20K, but would drill off no further. This worked to slowly pushed through the plug down to the bomb section. Aluminum bomb section drilled off with 1K WOB and torqued up some as anything over 1K WOB was applied. Circulated the rubber and aluminum out of the hole and then came up to check the bit before running in the hole with singles. Tag up on top of cement at 2617'. Lay down joint 74 and circulate hole clean. Pressure tested casing to 3000 psi. POOH and stand back 24 stands 5" DP until 11,500’ of pipe is in the derrick and hole. Picked up and racked back4 stands of DP to make room to pick up 4 stands of HWDP in derrick for drilling out the shoe track and 20' of new formation for mud swap and FIT. Tagged TOC @ 2617' and bit drilled slowly from 2618' to 2626' with dart rubber coming across the shakers at 2622'. Drilled cement well and slowed again from 2653' to 2664' with more plug rubber and some metal across the shaker over that interval. Drilled cement at 150 fph to 2706' where it stopped briefly, torqued up, and resumed drilling ahead. Circulate hole clean. Suck out Pits 1, 2 & 3 with Vac trucks to make room for new mud. Displace mud to 9.0 ppg LSND mud @ 5 BPM. Bit looked good on surface with 2 chipped teeth along the taper section but no other wear noted. Drill 20’ with 0.13 drilling hours for an average of 154 fph. Bit graded 1-1-CT-T-X-I-WT-BHA.

The mud motor will be utilized to maintain less than 2° inclination and remain in a 100' radius. The directional drillers will monitor drilling parameters to indentify when coals are drilled. Coal drilling guidelines and procedures will be followed to minimize risks while drilling coal. A 180' per hour ROP limit will be maintained to ensure good realtime MWD data density for quality logs. Short trips will be performed every 1000' to 1500' to maintain a good wellbore to run wireline logging BHA Report INSITE V7.4.20 Page 2Job No: AK-XX-0900525671 Well Name: Nunivak 2 OBJECTIVES tools. RESULTS A 7” SperryDrill 7/8 lobe – 6.0 stage motor with an adjustable kickoff housing set at 1.22° was made up with the 9-7/8” Halliburton SF56 PDC bit. Sperry MWD tools consisting of real-time directional, gamma ray, resistivity, density, and porosity and recorded azimuthal sonic were made up tested and initialized. There was not enough mud to perform a shallow pulse test and approximately 10 hours were spent building mud. Attempted to pulse test the tools with 410 GPM, but the shakers were running over. The shaker screens were changed from 100 to 50 API mesh and the MWD tools were then successfully pulse tested with 475 GPM. The logging sources were installed and the remainder of the BHA was made up and tripped in the hole. The assembly was tripping in to 2691’ where the pipe was filled and then the assembly was washed to bottom. Drilling began with 1 to 2K weight on bit with 140 to 160 ROP. Hard stringers were encountered from 2881’ to 3072’ which required up to 10K WOB with 130 to 175 ROP. Despite the higher WOB, the assembly dropped inclination from 0.67° to 0.48°. Continued to rotate ahead with 80 RPM and 500 GPM and the assembly was holding an average of 0.50° inclination at an average azimuth of 55°. Despite the low inclination, the wellbore was still walking away for the origin about 1’ per 100’. The ROP averaged 151’ per hour down to 3741’ with an average WOB of 4K. From 3741’ the ROP began to slow down to 104’ per hour. At the survey depth of 3767’, the wellbore was 33.5’ at a 55° direction for the well origin and still moving away at 1’ per 100’. A corrective slide was attempted at 3837’, but the top drive brake would not hold. The slide was abandoned after 7’ and the stand was rotated down so that top drive brake could be repaired. 30 minutes was spent attempting to repair the brake, but the cover would need to be removed to further investigate the problem. At 3932’, two bottoms up were circulated and the assembly was tripped to the shoe. 25K overpull was initially observed, but this fell off to 10K. No problems were observed pulling the assembly into the casing shoe. The top drive brake was investigated and a valve was found to have vibrated open open which was not allowing the brake to hold. The valve was shut and the brake successfully tested. The assembly was tripped back to bottom with no difficulties. A 25’ slide was made at a 240° magnetic toolface which turned the wellbore to 200° azimuth with a 0.79° inclination. The wellbore would now be moving 1.38’ per 100’ back towards the origin. The assembly was rotated ahead with 10K WOB and 550 GPM averaging 137’ per hour. Drilling slowed to 70’ per hour average at 4226’ and the WOB was increased 15K. Drilling became erratic with ROP rates from 30’ to 100’ per hour on stands. Any drilling breaks over 100’ per hour were treated as possible coal stringers and the assembly was worked up about 10’ after drilling small 2’ to 5’ intervals. 12 to 16K WOB was maintained while drilling with an average ROP of 78’ per hour from 4226’ to 5267’. While backreaming the stand to make a connection at 5267’, a swab appeared to go out on the mud pump. A short trip was planned at 5456’ anyway, so the decision was made to perform the trip early while performing repairs on the mud pump. No problems were encountered on the trip and the last stand was washed down in preparation for drilling. The just replaced swab was found to be leaking, so the liner would be changed. The decision was made to drill ahead with only one mud pump while repairs were made to the pump. Only 333 GPM could be obtained with one mud pump. This rate is below the 500 GPM minimum for the mud motor, but it was discussed to limit WOB to 5K and drill ahead cautiously. ROP averaged 56’ per hour with the reduced parameters, but MWD could not obtain detection while on bottom. The stands were drilled down to 5554’ without detection, so the stand was reamed at 180’ per hour to obtain log data. While performing the pump repairs, the fluid end was found to be worn and needed to be replaced. Unfortunately there was not a replacement on location, so the decision was made to trip out of the hole early to test BOP equipment. This would also allow the MWD tools to be read and have new batteries, since the XBAT memory would fill in about 4 days. The final MAD (Measurement After Drilling) pass was made while circulating bottoms up and building a sweep. A sweep was pumped and a flow check was performed before pumping a dry job and beginning the trip out. The assembly was tripped out without difficulty and the BHA laid down without incident. The BHA components were in good condition and the only wear found was about 1/2" of the leading edge of the stabilizer worn down, but the blades were still in gauge. The damage will not affect the performance or reliability of the tool and will be run again. The bit was very worn and graded a 6-7-RO-A-X-I-WT-RIG. The rung out damage was suspected to be from 1/2" diameter pebbles of chert while drilling conglomerates. The rig completed pump repairs and tested BOP equipment prior to picking up the new BHA assembly.

The mud motor will be utilized to maintain less than 2° inclination and remain in a 100' radius. The directional drillers will monitor drilling parameters to indentify when coals are drilled. Coal drilling guidelines and procedures will be followed to minimize risks while drilling coal. A 180' per hour ROP limit will be maintained to ensure good realtime MWD data density for quality logs. Short trips will be performed every 1000' to 1500' to maintain a good wellbore to run wireline logging tools. RESULTS BHA Report INSITE V7.4.20 Page 2Job No: AK-XX-0900525671 Well Name: Nunivak 2 RESULTS The 7” SperryDrill 7/8 lobe – 6.0 stage motor with an adjustable kickoff housing set at 1.22° from BHA #3 was re-ran with the replacement 9-7/8” Halliburton SF56 PDC bit. A new MWD gamma, resistivity and pressure while drilling collar was picked up because the previous PWD tool was slightly out of calibration. A new TM collar with a fresh pulser was made up to allow for a week of drilling. The directional module was swapped for a different tool so that the centralizer blades could be inspected after high sand concentration in BHA #3. The tools were initialized and pulse tested before loading the logging sources. The assembly was tripped into the shoe without difficulty and the drillpipe filled before continuing tripping in the hole. At 3500’ the trip rate was slowed due to pushing mud away. A stand was reamed down from 5456’ to bottom at 5554’ as a precautionary measure. The bit was broke in with light weight on bit as drilling resumed. 550 GPM, 80 RPM with 2 to 5K WOB were the surface drilling parameters. The wellbore position at the beginning of the run was 17.35’ in a 75.74° direction from the wellbore origin, but moving back with a 0.65° inclination and a 242° azimuth. The assembly was rotated down to 6795’ with no problems and an average ROP of 132’ per hour. The inclination held well to 6244’, but then began building to 1.39° by 6725’. At this survey depth, the wellbore was only 8.11’ away from the origin but would be moving further away at a rate of 2.43’ per 100’ and possibly building higher than 2° inclination. A 25’ slide was made with a 165°M toolface, but the slide only dropped the inclination to a 1.13°. The assembly was rotated ahead and the next two surveys dropped inclination to 1.04°. The survey at 7105’ showed that the inclination had climbed to 1.77°. There was a planned short trip to be performed at this depth, so the rig circulated a high viscosity sweep to condition the hole before starting the trip. On short trip, tight spots multiple tight spots were encountered which were worked with pipe reciprocation only until it pulled clean. Three spots between 6920' and 6600' pulled 15K over, five spots between 6472' and 6150' pulled 30K over, three spots between 6070' and 5950' pulled 35K over and six spots between 5870' and 5583' pulled 40K over, which was the maximum pull authorized by the company man. Trip back to bottom went well with no problems encountered. A 25’ slide was made at a 165°M toolface which dropped the inclination to 1.26°. Another stand was rotated and the inclination built to 1.34°. A 30’ slide was made at a 155°M toolface which dropped the inclination to 0.94° and another stand rotated which built to 1.16°. The wellbore was now 20’ from the origin at 7488’. A 40’ slide was attempted at a 135°M toolface, but the assembly hung up after 32’. The stand was rotated down and 22’ of slide seen dropped the inclination to 0.63°. The remaining 6’ of slide dropped the inclination further to 0.56° on the next survey. The next two surveys climbed to 1.03° and 1.59° inclination respectively. The wellbore was 25’ away from plan in a 320.68° direction at the survey depth of 7963’. Another 25’ slide was made from 8036’ to 8061’ with a 140°M toolface with a ROP of 21’ per hour with 3K WOB. The survey at 8058’ showed the inclination built to 2.21° despite sliding the opposite direction which should have dropped the inclination. The build tendency while rotating must be higher than previously and overcoming the slide correction. A 50’ slide at a 150°M toolface was began, but the assembly hung up after 31’. The assembly was reciprocated and still would not slide. 15’ was backreamed, but would still not slide. The assembly was rotated ahead 7’ with a 21’ per hour ROP and the slide was attempted again. 2’ was slide at a 7’ per hour ROP before deciding to rotate the stand down to see if the problem was formation related. The remaining 55’ of the stand was rotated down with an average ROP of 17’ per hour. The survey after making the connection showed the inclination continued to build up to 3.37°. At this point, it appeared that the bit may be undergauge and the assembly was hanging up on the string stabilizer which is 31’ behind the bit. A conference call was made while another slide was attempted. 5’ was slid at a 150°M toolface with 7K WOB with a 7’ ROP, before the decision was made to trip out and inspect the bit. A sweep was pumped and the hole conditioned before beginning the trip out. The trip out was good with tight spots encountered from 4630’ to 4530’ with 30 to 40K overpull. The tight spots were worked through and clean up and the trip out resumed. The HWDP and drill collars were racked back. The MWD tools were read and XBAT and TM hang-off collar were laid down. The remainder of the MWD tool string was racked back in the derrick to save time. The bit was inspected and found to be worn, but not as severely as suspected. The taper had worn teeth and the gauge was 1/16” under. No damage was found on the mud motor or string stabilizers and the stabilizers were in gauge. The mud motor was changed out as a pre-cautionary measure to trip in with a fresh tool to finish drilling the remainder of the well. The new motor adjustable housing bend was also increased from 1.22° to 1.5° to provide better directional response and reduce necessary slide interval length. A new MWD pulser and XBAT tool to provide a new battery and flow gear to provide another week of service interval.

The mud motor with a 1.50° bend will be utilized to to bring the inclination back towards 0°, bring the wellbore towards its origin, maintain less than 2° inclination and remain in a 100' radius. The directional drillers will monitor drilling parameters to indentify when coals are drilled. Coal drilling guidelines and procedures will be followed to minimize risks while drilling coal. A 180' per hour ROP limit will be maintained to ensure good realtime MWD data density for quality logs. Short trips will be performed every 1000' to 1500' to maintain a good wellbore to run wireline logging tools. RESULTS A 7” SperryDrill 7/8 lobe – 6.0 stage motor with an adjustable kickoff housing set at 1.50° was made up with the 9-7/8” Halliburton FX65 PDC bit. Sperry MWD tools consisting of real-time directional, gamma ray, resistivity, density, and porosity and recorded azimuthal sonic were made up tested and initialized. After a good shallow pulse test and loading the sources, the assembly was tripped to 2720’ outside the shoe. The drilling BHA Report INSITE V7.4.20 Page 2Job No: AK-XX-0900525671 Well Name: Nunivak 2 RESULTS line was cut and slipped while circulating the annulus volume at a reduced rate and centrifuging the mud. While tripping in at 4500’ the assembly started taking weight with 25k down and also pulled 45k over. After trying to work through the tight spot without success, the top drive made up and attempts to wash down with 300 gpm where not successful. The flow rate was increased to 450 gpm with rotary at 20 rpm and then later to 40 rpm and the tight spots were reamed. The reamed interval was from 4500’ – 4800’. The shakers were loaded up with cuttings during this reaming period. The trip in after this interval was without any further issues. 200’ off bottom the assembly started to take weight with 25k down weight. The pipe was filled up and the remaining two stands were reamed to bottom. Slide drilling was started at 8231’ and the assembly started hanging up 30’ into the slide. After reaming the last 10’ of the slide interval, the remaining stand was rotary drilled to the connection. The survey at 8248' showed an inclination of 4.52° despite 17' of slide seen. The build was attributed to the rotation at the end of the last run. The wellbore was 38' away from the origin. A 50' slide was made to drop the inclination. The assembly hung up at 8356' and 8362' which corresponded to lithology changes on the log. The remainder of the stand was rotated down with a 38' ROP. The next survey showed a 3.78° inclination which indicated the motor was giving us a 3.88° yield. The wellbore was 44' away from the plan at the 8344'. Another 50' slide was made to turn the wellbore back to the origin. The slide went well but hung up at 8433' and 8451'. The assembly was worked up for the first one and reamed for the second one before sliding was resumed. The remainder of the stand was rotated down and the survey at 8436' showed a 3.03° inclination with motor output of 1.89°. Slide drilling was started at 8509', but the string hung up at 8520'. The string was worked and sliding resumed when it hung up again at 8526'. The slide interval was reamed and another slide attempt was made with little success. After rotary drilling to 8535', another slide attempt was made without success as the assembly continued to hang up. Rotary drilling was resumed from 8535’ to 8555'. During the slide from 8555' the string hung up at 8562' and 8567'. The slide interval was reamed and attempts to slide again were unsuccessful. After rotating 24' to 8592' another slide of 8’ was put before the assembly started hanging up again, so the stand was rotated down to the connection at 8605'. The survey at 8534' showed the assembly had built to 3.13° inclination despite 46' of slide to bring the wellbore back to vertical. Sliding was resumed at a 135°M toolface, but the assembly hung up after 2' of drilling. While attempting to pick up and work the string, 40K of overpull was encountered. The string was slacked off to neutral weight and rotation was attempted but the rotary stalled out of 15K torque. The assembly was worked about 5 times before pulling free. About 10' at the connection depth was reamed before racking the stand back and reaming a full stand. No problems were encountered while reaming the section. Sliding resumed with varied parameters to improve on drilling, but very little differential pressure was observed even with up to 25K WOB. The flow rate was slowed to 450 GPM and increased to 575 GPM to see if lower or higher bit RPMs would drill with no success. After sliding to 8610' at a 2' per hour ROP rate, the slide was abandoned and rotation was resumed. ROP with 500 GPM and 40 RPM with 5K WOB was only 6' per hour. At 8611' the company man called and instructed us to make as much footage without regard to building inclination. The weight on bit was increased gradually to 12K and ROP picked up to a maximum of 9' per hour. At 8625' Company man called to inform about the decision to TD early and drilling was stopped. A sweep was pumped and the hole was circulated clean. The assembly was tripped out with only 20K overpull observed from 6950’ to 6945’. The HWDP, jars and drill collars were racked back and the BHA was laid down without incident. No visible damage or abnormal wear was noted on the MWD tools or mud motor. Upon inspection, the bit was observed to have been rung out and lost all cutters on the shoulder/taper area. The rig prepared to test BOP equipment for the required weekly testing interval.

The GeoPilot 7600 EDL rotary steerable will be utilized to build inclination to 30° and azimuth to 116° at 3800'. The inclination will then be built to 56°at 4700'. The plans calls for 3.00° doglegs till the end of build section. A 7600' tangent section will be drilled from 4700'. The inclination will then be dropped down to 50.65° before Well TD at 13,306'. Since the GP 7600 EDL will be utilized for this vertical sidetrack, the azimuth will have to be turned around to plan azimuth depending on the azimuth after sidetrack. Coal drilling guidelines and procedures will be followed to minimize risks while drilling coal. A 180' per hour ROP limit will be maintained to ensure good realtime MWD data density for quality logs. Short trips will be performed every 1000' to 1500' to maintain a good wellbore to run wireline logging tools. RESULTS Made up BHA #6 and during the confidence test, a low g-total of the DM was observed. The DM was laid down and replaced with the backup tool. The tools were confidence tested again, initialized and pulsed tested before tripping in the hole. The assembly was tripped in to 2251' and washed down with 100 gpm. No cement was observed by the casing shoe at 2700', so a bottoms up was circulated at 200 gpm. No cement was observed. The rig waited on cement another 8 hours. The MWD tools and GeoPilot were function tested with 450 gpm. Good detection and downlinks were achieved, but the GeoPilot experienced high g-totals while rotating and would not deflect. With only 0.66° observed at the GeoPilot, it was suspected that the housing was rolling in the casing and possible high friction from cement contamination causing the high g- total. After waiting another 8 hours on cement, tripped in the hole and tagged cement at 2700'. Weight was set to 5k then increased to 15K. Ratty cement was drilled to 2722' where it firmed up and continued dressing cement to 2730'. After making connection the sidetrack was initiated with the following parameters. 450 gpm, 5 WOB, 60 rpm, 100% deflection, 0° TF. ABI started trending up at 2745'. Deflection was reduced to 80% after 50'. At kelly down 2826', ABI was 5.20°. The survey inclination was 4.08° and azimuth 203.81°. After the successful sidetrack, the well bore was gradually turned to planned azimuth with next stand drilled with 60% @ 60L TF. At kelly down 2922', Inc was 7.02°, Azimuth 180°. The BHA Report INSITE V7.4.20 Page 2Job No: AK-XX-0900525671 Well Name: Nunivak 2-ST RESULTS assembly was then pulled into the shoe for mud swap. After changing the mud system to new mud from the tank farm, drilling resumed with -70L TF to turn azimuth around and build inclination slowly at the same time. After turning azimuth to 112°, the deflection was maintained at 55%, 10L TF to continue with the build. Flow was increased from 550 gpm to 580 gpm. A hard stringer was encountered @ 3826'. There was housing roll @ 3910' which lasted around 25’. The ABI dropped 0.60°. The rotary was dropped down from 120 rpm to 60 rpm and flow from 580 gpm to 550 gpm to help reduce the washing around the cutters to eliminate the housing roll. Drilling started getting ratty around 3967. The rig floor was rattling at 120 rpm and very light weight. RPM was reduced to 60 rpm. While trying to build with 70% deflection at 4030', there were indications of hanging up. A “Home” command was downlinked. ROP gradually increased to 110 fph. After drilling 7', the deflection was increased to 60% and HS to continue with build. At 4060', a very hard formation was encountered. RPM was reduced and weight on bit gradually increased to improve ROP. ROP avg for the stand drilled down was 16 fph. There was no build while drilling through these hard spots. There was housing roll at 4135'. Flow was reduced to 550 gpm to counter the problem. The ratty drilling continued while drilling through hard stringers with 80 rpm. At 4173’, Dril N Slide and EZ Glide lubes (3 % and 10 %) were introduced into the mud system to prevent contaminating cuttings. Formation between 4217’ – 4218’ was drilled with over 1.5 hours with 22k – 25k WOB. Samples showed cemented sands and siltstones. A hi-vis sweep was pumped. After monitoring the well and pumping dry job, the assembly was pulled out for penetration rate. There was 10 – 20K over pull between 3800’ – 3600’. The bit was graded 3-4-BT-A-X-I-CT-PR.

The mud motor with a 1.50° bend will be utilized to finish the build section to inclination 56.75°, azimuth 116° with 3.5° doglegs. The directional drillers will monitor drilling parameters to identify when coals are drilled. Coal drilling guidelines and procedures will be followed to minimize risks while drilling coal. A 180' per hour ROP limit will be maintained to ensure good realtime MWD data density for quality logs. Short trips will be performed every 1000' to 1500' to maintain a good wellbore to run wireline logging tools. RESULTS BHA # 7 was made up and tripped in the hole. The last stand was washed down to bottom. A 30’ slide was done to continue with the build. The formation was very soft during the first slide interval which resulted in a 5.5° motor output. The parameters used were 12k wob, 550 gpm, and 100 psi differential pressure. The assembly also showed a drop and right hand turn tendency during the first two stands of rotary. The slide intervals were increased to 55’ to counter the soft formation and also the rotary drop tendency. At 4473', the formation started hardening while sliding with 15k wob, 550 gpm, 150 differential pressure, 65 fph rate of penetration. Motor output on the next slide gave 6.8°. The slide intervals were cut down to 35' while continuing with the build to 56°. After finishing the build, the sail angle for the tangent was held at 59° to catch up with plan after discussion with Onsite geologist and Company representative. Once 59° inclination was achieved maintenance slides were performed every two stands. At 5623’ the rate of penetration dropped down to 20 fph with erratic torque. The mud log samples showed clay. A 30 ppb nut plug sweep was pumped which helped in unballing the bit. ROP increased back to 80 fph after the sweep was pumped. Maintenance slides of 20 – 25’ were performed as needed to keep borehole above well plan. The top of the Suntrana formation was called by the geologist at 6848’ MD. The hole took 20 bbls. At 7064' a pressure spike was observed. The concern was it was a cone dragging. After drilling to 7125’ MD, decision was made to pull BHA Report INSITE V7.4.20 Page 2Job No: AK-XX-0900525671 Well Name: Nunivak 2-ST RESULTS out of the hole due to pressure spike and pick up the GP7600 EDL rotary steerable system and condition mud on the trip. Pumped sweep around and five stand were pulled on elevators. Assembly pulled smooth and a dry job was pumped. At 6699’ attempted to pull on elevators however 40K overpull was observed. Washed up to 6587' then attempted to pull without pumps to 6524' but observed 40K overpull. Backreamed out from 6524' - 5782'. Attempted to POOH with pumps only to 5507'. Assembly was trying to pack off while pulling 35k over. Continued backreaming out of hole from 5507' - 4075'. A bottoms up was circulated and lot of clay was observed over the shakers. s. Attempted to pull on elevators from 4075' - 4024'. Assembly pulled 30-40K over. Continued backreaming out of hole from 4024' - 2922'. Two bottoms up were circulated. The assembly was pulled out on elevators from the shoe. HWDP/Jars were racked back, the MWD tools were read and the BHA laid down. The bit graded 6-7-CI-N-F-4-BT-BHA.

The GeoPilot 7600 EDL rotary steerable will be utilized to drill the 56.65° tangent section to 12362'. The inclination will then be dropped down to 50.65° before Well TD at 13,306'. Coal drilling guidelines and procedures will be followed to minimize risks while drilling coal. A 180' per hour ROP limit will be maintained to ensure good realtime MWD data density for quality logs. RESULTS Run 800: BHA #8 was made up and tripped in the hole to the shoe, where the mud was circulated and conditioned. Drilling was started with 575 gpm and 150 rpm. The GeoPilot initially showed a drop and right hand walk in neutral. Lubes were introduced at 7500’and the percentage was increased to 2% as drilling continued. The borehole was being maintained 3-5’ above well plan. The on bottom drilling torque and ECDs kept trending up as drilling continued. A short trip was performed at 8645’. The assembly was pulled out on elevators to 8223’ where 25k over pull was encountered. Assembly was backreamed to 7020’ where a weighted sweep was pumped around. The assembly was tripped in to 8445’ where 20k drag was noticed. The assembly was reamed down to bottom and drilling was resumed. The on bottom torque kept increasing and was around 15 – 17k-fp at 9402’. The Coman decided to circulate a bottoms up at this point to help lower the ECDs. The circulation did not help in reducing the ECDs. Drilling continued to 10071’ where on Kelly down 25k increase in up weight and 12k additional slack off was observed. Decision was made to short trip one stand early. A bottoms up was circulated. Due to the high ECDs and torque, the assembly was backreamed out of the hole. The short trip decision was then changed to pull out of hole for BOP tests. Backreaming continued to the shoe after which the assembly was pulled out on elevators. The BHA was racked back. The bit was graded 1-1-ER-N-X-I-NO-BHA. The hard spots encountered during this run where drilled by reducing the rotary to 70 rpm and gradually increasing weight to 22k. The GeoPilot held inclination with a 25% deflection throughout the tangent section.

The GeoPilot 7600 EDL rotary steerable will be utilized to drill the 56.65° tangent section to 12362'. The inclination will then be dropped down to 50.65° before Well TD at 13,306'. Coal drilling guidelines and procedures will be followed to minimize risks while drilling coal. A 180' per hour ROP limit will be maintained to ensure good realtime MWD data density for quality logs. RESULTS Made up BHA #9 and tripped in the hole to the shoe at 2700’ where the first mud displacement was made. Continued tripping in the hole on elevators to 8760' where string took 50K weight. After slow progress down to 8900' decision was made to displace again to new mud. To continue BHA Report INSITE V7.4.20 Page 2Job No: AK-XX-0900525671 Well Name: Nunivak 2-ST RESULTS with displacing mud the BHA was reamed down to bottom. The hole packed off at 9542' in a coal bed interval. Coal drilling procedure was followed and the BHA was reamed down to bottom to commence drilling. Once on bottom drilling commenced with 120 rpm, 550 gpm, 8k WOB. Toolface was set at 10L with 20% deflection during the stand. This maintained the inclination but the azimuth turned right at 1.64° /100’ indicating a strong right hand walk and drop tendency. After 42’ at 70L @ 24% deflection to get the azimuth over from 118.32° to 116.87° a tool face an average tool face of 20L with 33% deflection to maintain the 116 azimuth and bring the inclination up from 56.27° to 57.79°.The on drilling torque was around 20k-fp with high stick slip. The rotary was increased from 120 rpm to 150 rpm which reduced the stick slip but drilling torque remained high. Nut plug sweeps were pumped at 10169' and 10215' to help clean the hole and reduce torque. At 10337' the string torqued up and almost stalled the top drive. The string was picked string up 30' to let cuttings move up and also reduce the torque. Another nut plug sweep was pumped at 10337'. Since the top drive had started stalling more often due to high torque, the drilling torque limit was increased to 21.5k-fp at 10441’ and rotary down to 120 rpm to help maintain a consistent 75 fph penetration rate. At 10829’, the rotary was further reduced to 100 rpm to help reduce stalling the top drive. The drilling parameters were 100 rpm, 8-10k WOB, 21k-fp torque, 600 gpm. Coal seams were drilled at 10237’-10267’MD, 10276’-10281’MD,10346’-10356’MD,10385’-10395’MD,10435’-10442’MD,10506’10519’MD, 10569’-10580’MD,10608’-10620’MD. When drilling through the coals the top drive would struggle and almost stall, this happened a lot throughout the run. At 10912’ it was decided to pull out of the hole for high torque. After circulating out sweep, back reaming was commenced to chase cuttings and clean the hole. While back reaming out of the hole the assembly experienced a high amount of stick slip along with multiple packs offs that correlated with coal seams on the log. A sweep was pumped at the casing shoe. After the sweep was seen at surface the assembly was pulled on elevators without incident. No visible damage was seen on the tools at surface. The bit graded 1-1-PN-N-X-I-NO-TQ. Drilled 841’ in 14.18 bit hours for an average rate of penetration of 59.30 fph.

A 7” Sperry Drill will be utilized to drill the 56.65° tangent section to 12,362'. The inclination will then be dropped down to 50.65° before Well TD at 13,306'. The motor will be set at 1.22° for any slide corrections needed. Good coal drilling guidelines and procedures will be followed to minimize risks associated with drilling coals. RESULTS BHA # 10 was made up and tripped in the hole. Shallow pulse test could not be performed due to rig pump problems. The BHA was tripped in with the rest of the HWDP and 30 joints of drill pipe from pipe shed. Shallow pulse test was attempted which was good. After tripping to the shoe, the drilling line was cut and slipped. The BHA was tripped in on elevators with pipe filled every 1500’. The drag was around 15-20k during the trip in. A tight spot at 6870’ was worked by orienting the string ¾” turn. Further tight spots were encountered at 8867', 9360' and 9570'. The trip in was continued to 9715' where the string started to take 35k over and hold. The top drive was made up and oriented to work string through tight spot with no success. The Company representative was informed about reaming through tight spot. With rotary at 20 rpm and 200 gpm reaming was commenced when the rotary stalled. The rotary was increased to 50 rpm. Stand pressure was holding 1500 psi indicating pack off with returns at 10%. Decision was made to back ream above coal seams. String was back reamed from 9715’ to 9439’ with 50 gpm, 1500 psi and 5%-10% returns. At 9439', the rotary stalled and the string could not be worked up or down. Attempt to fire jars failed and work was continued to get pipe free with no success while waiting on fishing tools. Old mud from tank farm was transferred to the active pits and circulated due to downhole losses. Returns were established and pumps were staged up slowly to 510 gpm at 1550 psi. The rig was able to fire the jars in both directions but with no success in freeing the string. Drill string was severed at 8586’MD. BHA was lost in hole.

Out = 62.51 OBJECTIVES This BHA will be utilized to sidetrack Nunivak 2ST at a KOP of 8487’ and drill the 6 3/4" hole section to the planned well TD of 13,450'. A 5” Sperry Drill 6/7 6.0 set at 1.22° will be utilized to build inclination to 58.08° and turn the azimuth to 115° at 8587'. The inclination will then be built to 58.66° and the azimuth turned to 90.3° at 9287’. Then using the natural right hand turn and drop tendency of the formation the Inclination will be dropped to 56.7° and the Azimuth will be turned to 125°. The plan calls for 3.00° doglegs till the end of turn section. Coal drilling guidelines and procedures will be followed to minimize risks while drilling coal. RESULTS Run 1100 was made up and run in the hole. The company rep decided to add 14 extra joints of HWDP to the 16 planned for our BHA for a total of 30 joints. Cement was tagged up on in casing at 8019’.Hard cement was drilled 8019' to 8390', A conference call was made with the Drilling Engineer and it was decided to start time drilling from 10' below the shoe. As soon as the assembly got out of the shoe at 8380', there was no cement, It started firming up again from 8387’; It was decided to start time drilling as planned from 8390'. Time drilled from 8390' to 8392' @ 5min/ inch, from 8392' to 8394' @ 4min/inch, from 8394' to 8407' @ 3mins/inch –holding a 70L TF 275GPM 2300PSI, not seeing any changes in WOB or seeing any differential pressure, at this point there was no formation in the cuttings it has been 100% cement. At 8407' stopped time drilling and pulled back into the shoe so Halliburton Cementer's could rig up and perform a LOT. An equivalent mud weight of 11.65 was achieved from the leak off test. The assembly was tripped back in the hole to 8407', where it was decided that it might be easier to side track using a 130L tool face. Time drilling was continued at a 130L tool face at 3min/inch. SDL reported to Sperry DD that the cuttings sample at 8410' showed that the cement was getting softer. The next cuttings sample at 8413' showed that the cement was firmer but still not hard. Cuttings samples had been 100% cement up to this point. The first clean survey at 8402' showed a 2° change in azimuth. At 8429’ the decision was made to quit time drilling and begin control drilling at 10'hr. A cuttings sample at 8470' show a 30% concentration of formation, samples were taken every 5'MD, with the concentration building up each sample to 90% @ 8510"MD. Control drilling was continued at 10'/hr. to 8537'. Circulate bottoms up where the BHA Report INSITE V7.4.20 Page 2Job No: AK-XX-0900525671 Well Name: Nunivak 2-ST RESULTS geologist confirmed formation percentage was at 90 % and that the assembly successfully side tracked from the old well bore. The next two stands were rotated down. Magnetic interference was experienced on the first two surveys due to the fish. On the next three stands, three slides of 32' were performed to bring the inclination back up and turn the well left. The inclination was brought up to 59.4° so the next three stands were rotated. In rotary the assembly was dropping 0.30° and walking right 0.50°. Slight Stick slip and vibration was experienced during the back reams. 50RPM seemed to work the best during the back reaming. On the next stand the BHA dropped 0.36° and turned 0.56° to the left. So a slide was put in at 30R to counter the drop and turn. On the next stand the BHA built 0.05° and turned 0.68° to the right. After rotating another stand down the BHA built up 59.21 and turned to the left again 0.31°. So a slide at 120R performed to counter the build and left hand turn. The next stand down survey at 9752' showed assembly is dropping 0.11° and turning left 0.23° in rotary. A slide @ 70R was performed. With the BHA wanting to walk left, the plan of rotating ahead and letting it walk right was not going to work, start putting 30' slides every stand to turn the well right due to falling behind on the turn. AT 10100' the drilling slowed down and sliding became difficult. A slide of 9' was performed and then rotated 5' to get out of the hard formation. Slide another 4' with the same results, rotate 6 more feet and attempt to slide again with no success, due to the motor stalling. Rotated to 10177' circulated a bottoms up and performed a wiper trip to shoe. The first three stands of the wiper trip pulled with no issue, pumping was required on the next two stands, after that reaming was required all the way back to the shoe. Once in casing a sweep was pumped and a bottoms up was circulated. The trip back to bottom went good no tight spots on the way in. Wash last stand down. While lining up to slide the massive amounts of coal started to come over the shakers. The pipe was worked while circulating; it took 45 min for the shakers to clean up. Sliding had become very difficult due to the formation the mud motor would stall easily when put on bottom. Rotated ahead to get into better formation. Managed to put in 2 and a half good slides, turning the well to 120.56° and started having problems again. Had a discussion with the Drilling engineer Mike Cook at 10560' who said to rotate the next 1000' keeping the inclination between 50° to 55°+ and the Azimuth between 120° to 125°+. Correction Slides will be made if the assembly goes outside this window. After drilling down to 10949', while making up the new stand the stump connection got galled while screwing into it. The pipe sat without movement for 30 minutes while trying to rack back the stand that was just picked up. After racking back the stand the driller latched up the elevators to move the drill string, pulled 40k over without breaking over and the jars didn’t fire. A head pin was screwed into the stump and pumped through the cement line to get flow. Worked stuck pipe, pulled 80k over got the jars to fire and the string came free. The top joint of stand 102 was laid down and stand 103 was racked back due to a galled pin connection. Picked up stand 104 it became stand 103 drilled it down. A single from the pipe shed was picked up to replace the galled one laid down from stand 102. From 10949 drilling parameters were varied to control the left hand turn tendency of the BHA. AT 70 RPM 6K WOB the assembly dropped 0.41° and turned 0.07° right. At 80RPM 6K WOB the assembly dropped 0.40° and turned 0.04° right. For the time being the RPM’s were kept at 80 due to the better hole cleaning and ROP. At 11528' a sweep was and the hole was circulated clean, after that sweeps were pumped every stand, started getting back loads of coal at the shakers. Reducing to 70 RPM’s with 6/7 WOB helped to decrease the rate of drop in inclination and get a slight right hand walk, enabling us to rotate ahead longer and still stay in the window given by Mike Cook. A survey at 11584' showed that the assembly had built 0.50° and walked left 0.45°. The hole was drilled down to 11816', it was circulated clean and the decision was made to POOH for BOP test. POOH on elevators from 11720' to 11624', after that 25K over pull was observed so back reaming out of the hole was commenced. The assembly started torqueing up and packing off @ 9620' went back down and lowered the flow to get returns back, slowly brought the flow back up and worked up slowly through two large coal seams to 9582'MD and again at 9060'MD the assembly attempted to pack off again, so reduced pump rate and worked pipe to establish full returns, experienced full stall stick slip but was able to work thorough the coal seam. The rest of the trip back to the shoe went good. A sweep and a dry job were pumped at the shoe. None to slight vibration was observed during drilling, short events of high stick slip and full stall were observed during some of the back reaming. No visible damage was seen on the tools at surface. The bit graded 0-1-CT-G-X-I-HC-BOP. Not including the time or footage to side track the assembly drilled 3280’ in 39.97 bit hours for an average rate of penetration of 82 fph. Slide footage was 412’ and accounted for 13% of the footage drilled and 29% of the drilling time at 11.44 hours for an average rate of penetration of 36 fph. Rotary footage was 2868’ accounting for 87% of the footage drilled and 81% of the drilling time at 28.53 hours for an average rate of penetration of 100 fph.
