Page 1 of 1 Schwartz, Guy L (DOA) From: Schwartz, Guy L (DOA) Sent: Monday, June 25, 2012 10:29 AM To: 'Michael Cook' Subject: RE: Walakpa#11,#12,#13 -Surface Hole Section Excess Cement Thanks Mike for the follow-up on the surface cement on these wells. It appears due to the near gauge hole and rough estimations on the surface returns were the cause for the appearance of possible over displacement. I agree that the casing were properly cemented to surface. Guy Schwartz Senior Petroleum Engineer AOGCC 793-1226 (office) 444-3433 (cell) From: Michael Cook[mailto:mcook@petroak.com] Sent: Monday, June 25, 2012 10:01 AM To: Schwartz, Guy L(DOA) Subject: Re: Walakpa #11,#12,#13 - Surface Hole Section Excess Cement Guy, Per discussion regarding excess cement returns to surface while performing primary cementing displacements onn we • . 1. Wale •a#11 Zf f—OG 2. Walakpa#12 3. Walakpa#13 In each well,the surface 12-1/4" hole section was drilled with "gauge" hole to surface hole section TD. A lead slurry HES Type "L",85 sxs,4.31 cu.ft/sxs.,followed by a tail Type"C" slurry at 0.95 cu.ft/sxs. A 40 bbl. dual spacer was pumped ahead of the lead slurry. An open top containment tank positioned at the end of the 16" divert line was used to collect excess slurry. In each surface hole displacement an approximate volume of 50-55 bbls was noted as returns to surface.Cement returns to the open top tank in each well surface cementing displacement was confirmed.

Walakpa #12 Shut In Pressure at Surface: 916 psi Initial Rate: 1.19 MMSCF/D with tubing pressure of 914 psi. Walakpa #13 Shut In Pressure at Surface: 925 psi Initial Rate: 1.14 MMSCF/D with flowing pressure of 923 psi. As the demand for gas in Barrow is very low at this time of the year, we would like to postpone 4 point tests until next winter to prevent having to flare and thus wasting of the gas. Additionally, at that time the new SCADA system will be fully functional and allow for easier control of the wells for these tests. Until the SCADA system is fully operational, the wells have to be tested manually, which involves tundra travel by Rolligon during the summer season. Peter J.Stokes, PE&MBA Please confirm that we can postpone these tests.

Technical Report Title Date Client: North Slope Borough Field: Walakpa Gas Field Rig: Kuukpik 5 Date: March 4, 2012 LMWD and Directional Drilling End of Well Report Walakpa 11 WELL INFORMATION Customer :North Slope Borough Well Name :Walakpa 11 AK-XX-0008370345Job Number : Rig Name :Kuukpik 5 Field Name :Walakpa Gas Field Country :USA End of Well Report DIRECTIONAL DRILLERS Driller 1 :Mark Brouillet Driller 3 : Driller 2 :Art Morgan Driller 4 : JOB OBJECTIVES Objectives Per Wellplan: Walakpa #11 is planned as a high-angle, infill gas production well east of Walakpa #3, south of Walakpa #5, north of Walakpa #6, and west of recently drilled gas producer Walakpa #12. This location is in the mid-section of the Walakpa Gas Field. The production hole is planned for 1,500 feet. The well will be drilled west from the pad, south of parallel 2D seismic line 89-22 and will cross two perpendicular seismic lines running N-S, 89-59 and 89-79. Also, three development wells in the area provide structural controls throughout the well trajectory, Walakpa #3(6600’ offset), Walakpa #5 (3000’ offset), and Walakpa #6(5100’ offset). Walakpa #11has a planned offset of 4800’ from TD to TD points. Directional Objectives: 1. No Safety or Enviromental violations, No Accidents or Injuries. 2. Drill the Walakpa 11 well under days and under budget. 3. Keep wellbore tortuosity low. 4. Apply lessons learned from previous Barrow gas field wells to Walakpa 11. 5. Apply new directional plan and make improvements as needed to lower dogleg rates. JOB SUMMARY Walakpa 11 Directional summary: This well was drilled with many improvements to the directional plan. Lessons learned had been moved forward from the past 3 Barrow gas field’s wells drilled and applied to the Walakpa 11 well. Surface section was drilled with low doglegs and in a fashion that aided in reducing dogleg rates and slide percentage in the intermediate section. Both surface and intermediate went very well and the rig was well ahead of the days vs. depth curve at this point. The surface casing was run and cemented with good cement returns to surface and the plug bumped. Intermediate section was drilled below the 5° dogleg rate proposed in the directional plan. Slide percentage for the intermediate was at 27% which is the lowest slide percentage of any of the Barrow wells drilled this season. At the end of the intermediate section there was no doubt that wellbore tortuosity had been kept very low and good weight transfer would be available to run a motor in the horizontal section upcoming in the production hole. Problems were seen almost immediately after drilling out of the 7" casing with the motor BHA. Up to this point the Barrow gas wells production sections had all been drilled with the geo-pilot rotary steerable system. The motor assembly started out with far lower then expected rates of penetration this was surprising and expected to improve once the BHA reached the Walakpa sands. The BHA did get into the sands but an accumulation of hours would soon be the demise of the BHA as the bit had to be pulled due to hrs. This was an unplanned trip and turn around time for the BHA was lengthy with neutron density tools in the MWD package and downloading all logging data at surface etc. With a new BHA in the sands rates of penetration were far better but still not optimal. The new BHA was well on its way to drilling the section to TD when it exited out of the bottom of the pay zone. Several options were discussed with the decision made to attempt an open hole sidetrack. This may not have been the best option as the rig had a scheduled BOP test to begin within 24 hrs. The assembly was pulled back to 4,325' and troughed to 4,360'. Time drilling was initiated at this depth with no success time drilling continued and at 4,370' the assembly was time drilling with a 150° right toolface setting in an area which previously had a 10' slide at 15° left. This was a good area to sidetrack but the attempt was not successful. Due to time constraints concerning the BOP test the attempt was ended and the assembly used to clean out to the 4,708' MD Page 1 of 7 JOB SUMMARY where the well was officially called TD. Many BHA suggestions are to be presented to the customer in an attempt to further improve drilling on the last 2 remaining wells. A lot of very good things were done on the Walakpa 11 well and further improvements will be made by the directional team on location and in town. BHA SUMMARY BHA # 1 (Run 100) This BHA was a simple motor dumb iron assembly tasked to drill sufficient rathole to enable picking up the steerable motor assembly with MWD all the way to the jars. It Tagged cement at 48' and drilled to a depth of 221' it was then pulled from the hole for BHA # 2. The bit and motor were run on BHA # 2 BHA # 2 (Run 200) This BHA met all objectives set forth. Drilling hrs were kept low as the BHA performed very well. Wellbore placement was beneficial in reducing dogleg rates in the 8-1/2" intermediate section. No NPT time was encountered. Motor output was good from the beginning with motor yielding a strong 6.5° dogleg capability kicking the well off of vertical. The motor capability averaged 10.6° once above 7° inclination. No steering issues with the bit and motor combination. All tools inspected on surface with no visual damage. BHA # 3 (Run 300) The BHA used a re-run PDC Bit and also re-ran the 6-3/4" Sperrydrill motor used on the Walakpa 12 intermediate section. Both bit and motor performed as expected. The bit was easily steered and motor output was consistent throughout the interval. Bit and motor coupled with good MWD detection at all times while sliding made it very easy to build the required angle. BHA performance was as predicted and it was very easy to drill the section to TD. As with the surface BHA no damage was found to any of the BHA components when examined on surface. Specific information pertaining to bit or motor can be found in this report under each components heading. The intermediate section total footage was only 2,218' and inclination had to be built from 30° to a projected 81° at TD in this short distance. This was done with dogleg rates averaging 3° per 100' far lower then the 5° per 100' in the directional plan. This section also had a tangent section of roughly 800' which required only 1 slide for azimuth correction. Considering all this the assembly performance would have to be considered excellent by any standard. BHA # 4 (Run 400) BHA had slow ROP with 34% of the footage drilled not in the Walakpa sands. This percentage of footage was due to the assembly having to drop 39' in TVD before intersecting the Walakpa sand. Once in zone ROP did improve. With a large amount of time accumulated on the bit the BHA had to be pulled as the bit was run for 47.04 hours which according to the HDBS rep was over the upper threshold limit for the bit. The assembly drilled a total of 849'. ROP average for this BHA was a dismal 18 fph. BHA # 5 (Run 500) This is the same basic BHA as BHA # 4 with the exception of a new bit and dropping out the non mag spacing collar and the ILS stabilizer. The assembly did use a new 4-3/4" motor as motor was changed as a precaution due to the hours accumulated on the ABI Battery. BHA drilled from 4,275' to 4,708 (TD) The assembly showed noted ROP improvement at 41' per hour. The assembly was being control drilled as far as ROP for logging quality. This BHA did reach ROP over 100 fph in the sand. The BHA went out of zone due to a formation dip change and the well was brought to TD with the BHA only drilling 433' Bit # BHA CHART Run #Motor #Hole Size MD In MD Out TVD In TVD Out Inc In Inc Out Azi In Azi Out Time Drilling Time Circ (in) (ft) (ft) (ft) (ft) (deg) (deg) (deg) (deg) (hr) (hr) 0100 1RR 1 12.25 103.00 221.00 103.00 220.97 0.63 2.13 285.82 256.64 3.67 0.50 0200 1RR 2 12.25 221.00 1208.00 220.97 1160.32 2.13 30.95 256.64 259.82 18.37 11.34 0300 2 3 8.5 1208.00 3426.00 1160.32 2259.96 30.95 77.35 259.82 261.20 19.57 26.78 0400 3 4 6.13 3426.00 4275.00 2259.96 2327.44 77.35 84.29 261.20 256.06 47.04 9.15 0500 4 5 6.13 4275.00 4708.00 2327.44 2358.88 84.29 85.32 256.06 250.16 10.70 10.40 Page 2 of 7 MOTOR RUN SUMMARY 8" SperryDrill Lobe 4/5 - 5.3 stg W/ adjustable bend set at 1.5° was used in BHA # 1-2. Motor performance was good. Flow rate average of 535 gpm with BHA # 2 was not taxing the motor in any way. This motor delivered good dogleg rates averaging 10.6° even with a low flow rate and minimal 10k bit weight. Max bit weight during this run was 23k. The motor was not worked hard and delivered good over all performance. With no visible damage when inspected at surface. 6 3/4" SperryDrill Lobe 6/7 - 5.0 stg W/adj bend set at 1.5° used in BHA 3 (Run 300) Motor output averaged close to 8.5° per 100' which with the PDC bit should be considered good output. The motor was achieving 12.5° per 100' output towards the end of the run with higher angle in the hole. This motor was re-reun from the Walakpa 12 well. Motor easily drilled the section with no motor stalls and good performance throughout the interval. Motor was flushed with water and drained at surface. No visible damage was observed the motor lower sleeve stabilizer was packed heavily with clay. 4 3/4" SperryDrill Lobe 7/8 - 2.9 stgW/ABI 1.5° bend setting .30 rev/gal. Slow speed motor selected to be paired with the HDBS QH1R milltooth bit. Strong directional control was expected with this motor. At bit inclination was critical for keeping the assembly on path per geology's instructions. Motor performance was good even though ROP rates were very low. The low ROP rates are more associated with drilling 34% of this motors total footage in the shale formation above the pay zone. This motor was run on BHA # 4 and the assembly was tripped due to high bit hours. As a precautionary move only a new 4-3/4 slow speed motor was picked up with BHA # 5 the ROP improved due to drilling in the paysands. Both motor run performed well. The at bit inclination had excellent detection levels throughout both runs.

Surface was drilled with no hole problems. Flow rate adjusted so shakers could handle the clays coming across them. Rig did stop once to circulate when the BHA exited the base of the perma frost and a heavy load of cuttings brought to surface. Directionally the section went very well. Dogleg rates were kept low assembly landed at casing point high of plan to benefit intermediate section. Strong motor performance with the adjustable bend setting of 1.5° delivering 10.6 ° average dogleg capability. With the hole circulated clean the BHA was tripped to the flex drill collars. Some tight spots were worked through during this trip. Assembly was then run back to bottom and the wellbore given a final circulation prior to pulling out of the hole and laying down BHA. Casing was run to bottom with no hole problems seen. Cement job went well with cement to surface and the plug bumped. INTERMEDIATE HOLE SECTION 1 12-1/4" Surface hole Drilled from bottom of conductor at 103' with RKB included to 1,208'. Surface was drilled with no hole problems.

Heavy clays on this section were expected as the clay has been prevalent in all the barrow gas field wells. The clay made it necessary to keep flow rates averaging around 450 gpm while drilling the section. The lower flow rates and soap additives to the mud system made it possible for the shakers to keep up with the cuttings. The assembly was able to drill longer portions of footage before stopping to circulate the hole clean. Drilling hrs and slide percentage were lower on this section then had been seen in the previous wells. Dogleg rates were kept well below the 5° per 100' planned rate due to directional changes and adjustments made in the field. Once the section was brought to TD a short trip was done. The original plan was to pull to the surface shoe on elevators. This was not done due to swabbing. The assembly was backreamed to the surface casing shoe. On the way back in the hole it was also necessary to ream some sections. Once back on bottom while circulating the hole clean heavy clay's packed the flow line. Circulation continued until 510 - 520 gpm was reached and could be maintained. With the shakers showing very few cuttings across the screens the assembly was hoisted with no swabbing. On surface BHA tools were packed with clay and the bit was severely balled up. The 7" casing run went well with no problems getting casing to bottom. The cement job was also uneventful with the plug being bumped. This section was drilled in a timely manner with good wellbore positioning for the upcoming production section. INTERMEDIATE HOLE SECTION 2 PRODUCTION HOLE SECTION 6-1/8" Production was not drilled to the planned depth. The 7" casing was set at the depth given by geology. BHA was picked up used to drill out of the casing shoe building angle to be landed in the payzone at 88°. The Walakpa sands came in lower then prognosis. The 7" casing shoe set at 3,415' MD and the Walakpa sands were not intersected until 3,718' MD. Once in the payzone the directive from geology was to hold inclination at 87° to 88°. At the depth of 4,485' MD instructions were to lower inclination to 85.5° - 87.0°. These instructions changed at 4,518' MD with new inclination to be held at 84° this was to allow the wellpath to drop lower in section and once in the middle of the payzone the plan was to hold dip angle until TD. Unfortunately there was an apparent dip change with dip going from 87° to a flat horizontal position with no dip. This caused the wellpath to be steered out of zone and into the lower Kingak formation. TD for the section was called at 4,708' over 500' of pay sand had been acquired.

The assembly will be used to drill enough open hole to pick up the steerable motor assembly with MWD, Flex collars and jars. The conductor when cemented U-tubed with the cement coming up the conductor to within 48' of surface. The BHA will consist of bit, motor, float sub and 2 crossovers for a length of38.71'. With RKB being 23' on Kuupik 5 this will put the BHA 15' down into the conductor. Plan will be to drill down 3 stands of 4" HWDP to a total depth of 221' with 3' stick up. The cement will be drilled out with water and once the depth of 103' has been reached and the assembly is drilling formation it will be displaced to the spud mud. With the assembly reaching 221' it will allow for picking up the remaining BHA components to the jars with 16' of rathole in case of any hole sloughing. Once reaching the desired depth a quick circulation to make sure the hole is clean will be done. This BHA will then be hoisted to surface and BHA # 2 will be picked up. RESULTS BHA 1 (Run 100) Results for BHA were as expected. BHA drilled to 221' with no difficulty. ROP was far lower then expected. Bit weight was held to an average of 5k with rotary speed set at 40 rpm through out the run. This was done as the assembly was used to drill out cement in the conductor and there was no reason to rotate faster so close to the surface conductor. The assembly was picked up and tagged cement at 48'. Cement was drilled out and once new formation was showing at the shakers the water used to drill out cement was displaced with the spud mud. Bit weight set at 5k due to no drill collars and minimal BHA weight. Stacking more weight on the bit would be detrimental in holding this short drilling footage vertical. Once the 221' depth had been reached a short circulation was done and the assembly tripped to surface. The 3 stands of HWDP were racked back in the derrick and the crossovers broke off the top of the motor. The bit was pulled above the table cleaned and inspected. The bit was not broke off the motor as it would be re-run in BHA # 2 RECOMMENDATIONS No recommendations are needed for the assembly. Basic BHA used to drill a very small amount of footage.

Final inclination per directional plan will be 27.1°. Gyro will be run until magnetic interference is not seen on the MWD tools. The assembly will re-run the HDBS milltooth run on Walakpa 12 surface interval. This assembly is tasked with drilling the surface hole in one run. The objective will easily be achieved with this BHA. Motor bend setting will be 1.5° giving more then enough motor dogleg capability to acquire the directional profile requested. The Walakpa 12 well previously drilled made it necessary to change the directional plan for this well. Lessons learned on the previous well are to be implemented on the Walakpa 11 well. The directional plan was made with short notice and approved with full knowledge that changes to the plan would be carried out in the field. An attempt to set the wellbore high at casing point and lower the dogleg rates for the intermediate will be carried out. MWD logging package will include Gamma/Res with no onsite geologist will be present for the surface section. RESULTS BHA 2 (Run 200) results: Results for the BHA were very favorable. The assembly was made up and run in to 205' at this depth a gyro was run in the hole to orient the motor to highside at a 255° direction. The assembly was slid from 221' to 265' to kick the wellbore off vertical. The rotary was then engaged and the assembly rotated to 297'. At this depth a connection was made and a survey taken that showed the MWD directional tool was clear of any magnetic interference. The gyro was put on standby at this point. Motor output at the MWD survey depth of 257 showed a 6.57° dogleg capability. Fractional slide sets were made with motor output increasing as more angle was achieved. At 878' survey depth motor output was calculated at 10.59°. Motor dogleg capability average 10.63° from 878' to TD at 1,208' the assembly was comfortably ahead of plan and 3.5° ahead of planned inclination. The BHA had successfully drilled the surface interval with 34% slide percentage and 18.37 drilling Page 4 RESULTS hours. The objective of setting high and lowering the dogleg rate for the intermediate section was easily met. Dogleg rates for the intermediate section were lowered to a 3° rate down from the original Walakpa directional plan that had set this rate at 6°. The new directional plan had called for 5° rates in intermediate. This BHA is responsible for minimizing slide percentage in the upcoming 8-1/2" hole section. All objectives were met and no NPT time encountered with the BHA.

Actual TD will be determined by on site geology. This assembly will use the same PDC bit used on the Savik 2 and Walakpa 12 wells. The 6-3/4" Sperrydrill mudmotor with MWD package to include Gamma/Res/PWD /Directional. The directional probe will be 75' back from the bit allowing the use of long collar surveys for better survey accuracy with more non magnetic spacing below the directional. Having the Gamma /Res above the motor will be beneficial to rig site geology for picking casing point as these tools are in a configuration that moves these tools closer to the bit. The assembly will need to achieve a 3.2° dogleg rate to stay with the directional plan. Directionally the assembly will be required to build inclination from 30.6° to 87°. Azimuth will have a minimal change of less then 2° in direction from the 257° planned direction to a 255.6° direction. The BHA has the objective of reaching TD for the section in a single run. The usual steps such as the casing test, Mud displacement, Drill out of the casing float equipment and excess cement will be performed. The assembly will drill 20' of new hole and then be used for the LOT. With these tasks complete this assembly will begin drilling the directional plan with a planned flow rate of 500 gpm. Rotary speed will be set at 70 rpm with max rotary at 80 rpm. Planned bit weight will be 5k-20k. ECD's will be monitored closely and the hole will dictate if a short trip becomes necessary. Once reaching TD the assembly will of course circulate the hole clean. Prior to pulling the BHA the assembly will be short tripped to the surface casing shoe and back to bottom for a final circulation. The objectives for this BHA are easily achievable and the 75' bit to sensor distance does not pose any problems as far as staying close to the directional proposal. RESULTS BHA # 3 (Run 300) Results: Results for the assembly were excellent. The assembly did in fact drill the section in one run as per plan. Dogleg rates were Page 7 RESULTS held low and were far below the original 5° per 100' originally planned. This low dogleg rate was due to the wellbore placement in the surface interval. All dogleg rates were below plan for the entire section. This intermediate was drilled with 27% slide percentage which is the lowest in the Intermediate section for the 4 Barrow gas wells drilled so far. Lowest wellbore tortuosity was also achieved when compared to the previous wells. A new directional plan had been made for this Walakpa 11 well with involvement from the directional driller on location. This plan was also manipulated in the field by the directional personnel. With the full intent of each section benefiting the next section with focus to eventually optimize drilling the production section with a motor. The lessons learned applied from previous BHA's coupled with the new directional plan supplied the customer with better days vs. depth cost savings to go along with the smoother wellbore. The re-run HDBS FX2526 was again very easy to steer on the 6-3/4" Sperrydrill 6/7-5.0 performance motor. Detection was excellent through out the interval. Keeping in mind this intermediate section was only 2,218' in drilled footage it was no surprise to see the bit look the same as when it went in the hole. Motor dogleg capability averaged 8.43°. Max motor dogleg capability not surprisingly showed with the higher angle in the hole. This max motor output was 12.46° with hole inclination over 75°. Certainly also not surprising was the lower motor output yields came at the lower angle when drilling began for this section. The lower motor output rates were in the high 6° to low 7° per 100' range when hole angle was at 30°. This BHA performed very well in the tangent section of the hole with only one 20' slide made for azimuth. The tangent section length was only 867' regardless of the length of the tangent it needs to be noted that the assembly held angle very well. The 20' slide made was to counter the .35° left hand walk tendency. To say the section went well directionally is not to say that problems did not arise while drilling the section due to the large clay content in this section. Drilling was discontinued at one point to circulate the hole clean. Over 5 bottoms up were pumped until the shakers could handle a 510 gpm flow rate. Once the flow rate had reached this level a weighted hi-vis sweep was pumped. ECD's were lowered and drilling continued. Upon TD of the section a short trip was to be made pulling on elevators however due to swabbing conditions the assembly was backreamed to the surface casing shoe. When tripping back to bottom the need to pump and rotate took place. Once on bottom the assembly was circulating the hole clean when clay reached surface packing off the flow line. Additional time spent cleaning the hole was deemed a requirement. With the hole clean the assembly was pulled on elevators with no swabbing occurring. As the BHA was hoisted to surface most of the tool joints on the 4" HWDP had accumulated clay. The stabilizer above the bit was severely packed with clay and the bit was found to extremely balled up. No signs of actual damage were visible on the BHA components after cleaning off the clay. The 7" casing run that followed was very uneventful with casing going straight to bottom with no indication of hole trouble. The cement job was done with the plug bumped.

A tighter TFA should be implemented for next well. The bit drills a very large section of clay prior to reaching TD for the section. Higher flow rates have to be disregarded as the shakers are easily over run due to the high clay volumes. This may be an area that was over looked on this BHA and in hindsight could and should be captured as a lesson learned and discussion over different jetting options needs to be held.

Due to losses on the last well a well commander circulating sub will be run above the mwd package. The BHA will be tasked with several objectives starting out with the normal sequence of events. These tasks include testing casing, drilling float equipment, drill 20' of new hole, displacement over to the new mud and finally the FIT. With these objectives met the assembly will be put to drilling ahead. This assembly will be geo-steered throughout the production interval. The BHA will be expected to drill this production section to TD at the proposed depth of 5,324' MD. BHA will then circulate hole clean, short trip and a final circulation prior to being tripped to surface. RESULTS BHA # 4 (Run 400) Results: Page 10 RESULTS Results for this assembly were not favorable. The BHA had extremely slow ROP rates with very slow ROP while sliding to follow geological objectives. The production zone was far lower in TVD then expected as this assembly had to drill what should be considered an excessive amount of footage in shale. This needs to be taken into consideration when evaluating the slow ROP encountered. The assembly started performing directional work from 77° inclination with the intent of building to 88° inclination upon entering the pay sands. This assembly began drilling at 3,426' MD and did not enter the payzone until 3,718' MD 2,295' TVD. The 7" Casing shoe was set at 3,415' MD with TVD being 2,256' this BHA had to drill 292' while dropping 39' of TVD before leaving the shale and entering the paysand. This footage was 34% of the total footage for the BHA. The BHA drilled to 4,275' MD when it was decided to trip the assembly to surface due to hours on the bit. The assembly was inspected on surface with no damage to the BHA components and the milltooth bit was found to be in surprisingly good shape.

Objectives will remain the same for this BHA. Changes to BHA configuration did take place. These changes are minimal but are described as follows. The magnetic spacing collar run above the motor was dropped along with the ILS stabilizer. This moved MWD to short collar for surveys which showed it as a viable alternative to the long collar survey method previously used on BHA # 4. The objective for removing these components were to bring the logging tools down closer to the bit due to some formation uncertainties that were a concern to geology. Other then these 2 components and the new milltooth bit the BHA mirrors BHA # 4. Objectives will carry forward from the depth of 4,275' MD. RESULTS BHA # 5 (Run 500) Results: This BHA did not perform to what was expected. The assembly did show improved ROP's and was well on the way to drilling the section to TD. The difficulty began when the BHA exited the formation. Steering per geology was being undertaken with directive to drop angle from 88° down to 84° as it was thought this would place the assembly into the Page 13 RESULTS middle section of the pay sand. Apparently the dip had flattened out which in turn put the assembly out of zone at the bottom. The assembly was now in the Kingak shale formation. Projections were done and discussion held with management personnel in town to discuss options. The list of options were short call the well TD at 4,708' MD. Option two would be attempt an open hole sidetrack and the last option being drill ahead building angle and reacquire pay. The last option mentioned projected that the assembly would need to drill almost 400' before re-entering the pay zone. This option was no longer feasable. The final decision was to be attempting the open hole sidetrack. With a BOP test coming on in 24 hrs time was minimal. The assembly would have to complete the open hole sidetrack and drill ahead with hopes of obtaining more payzone then was to be given up when pulling back for the sidetrack. The open hole sidetrack attempt failed and this BHA was used to clean out to bottom to 4,708' MD. This was TD for the well. The BHA was used to circulate the hole clean and then tripped to surface. At this time Sperry personnel began organizing a waybill for shipping tools back to the R&M facility in deadhorse. Tools would be torn down and inspected then sent back to location for the next Barrow gas fields well. This BHA basically drilled 433' then was used to clean the hole in preparation for running completion.

Drilling After Action Review Employee Name: Mark Brouillet Date: 3-3-2012 Well: Walakpa 11 Hole Section: 12-1/4” Surface What went as, or better than, planned: The section went very well with low dogleg rates and good wellbore placement. Slide percentage was kept low This section greatly reduced the slide percentage and dogleg rate for the intermediate section. Due to improvements to the directional plan by the sperry well planner and directional driller on location. Difficulties experienced: No difficulties experienced on this surface hole Recommendations: No recommendations needed the section was drilled very efficiently Innovations and/or cost savings: Surface bit used was a re-run from the last well saving the cost of a new 12-1/4” milltooth. BHA components laid down with minimal breaks saved 1 hr rig time. LMWD AAR Page 1 REV 2 L/MWD After Action Review Well: Walakpa 11 Hole Section: 12.25" Surface Employee Name: Lucas Smith Date: 2/16/2012 What went as, or better than, planned: Excellent surface detection. Difficulties experienced: Logistical issues resulted in the entire surface hole being drilled without a back up Gamma / Res tool on location. Sperry's standard practice is to have a primary and back up on location for the current hole section. If an issue had arose where our only tool on location had malfunctioned the operation would have come to a halt. Recommendations: Have back up Logistical options with pricing already established so that if your primary logistical means is not able to be utilized, a back up plan can quickly be set into motion with minimal delay. Maintain the practice of keeping tools on location so that in the event of weather related logistical issues we have the tools we need to move the operation forward. Innovations and/or cost savings: Pulser was stuffed and pulled in the pipe shed saving 1 hr of rig time. 48+ hrs of time was saved by keeping unused tools on location. Had they been sent in we would have had no tools on location to drill surface hole and the entire operation would have been on hold due to our inability to transport tools via cargo aircraft. A rollagon would have been chartered to transport the tools from Deadhorse to Barrow which is a 48+ hour trip one way. Directional Drilling After Action Review Employee Name: Mark Brouillet Date: 3-3-2012 Well: Walakpa 11 Hole Section: 8-1/2” Intermediate What went as, or better than, planned: Section went extremely well. Dogleg rates were lower then planned with good wellbore placement. Slide percentage was 27% lowest percentage of any of the intermediate sections drilled in the 2012 Barrow gas fields project. Section drilled under planned time Difficulties experienced: No difficulty experienced improvements were made on this section Recommendations: Continue adjusting the directional plan attempting to lower the dogleg rates even farther for the next well Innovations and/or cost savings: Drilled the section efficiently under depth vs. days time saving many hrs of rig time LMWD AAR Page 1 REV 2 L/MWD After Action Review Well: Walakpa 11 Hole Section: 8.5" Intermediate Employee Name: Joe Granados Date: 2/22/2012 What went as, or better than, planned: Drilled the section in only one run, Good Detection during the run. Difficulties experienced: The Same logistical issues that prevented the surface section from being drilled without back up Gamma / Res Tool, also affected our ability to have a back up Gamma / Res sting for our Intermediate section. Once again, if an issue had arose where our only tool on location had malfunctioned the operation would have come to a halt. Recommendations: If weather or mechanical issues prevent the use of the primary means of shipping tools to the location, have alternate means of transport in place that would enable tools to get to location in time to be prepped for the drilling run. Innovations and/or cost savings: Pulser was stuffed and pulled in the pipe shed saving 1 hr of rig time. Keeping tools on location prevented the entire operation from coming to a dead stop due to lack of tools. Directional Drilling After Action Review Employee Name: Mark Brouillet Date: 3-3-2012 Well: Walakpa 11 Hole Section: 6-1/8” Production What went as, or better than, planned: The production section was drilled with a motor which had not been done on previous wells. Good weight transfer was available. Motor with ABI worked well with good ABI detection on both BHA’s run. ECD’s were kept low. Difficulties experienced: Slow ROP while drilling out of the 7” casing until reaching the pay zone. Bit trip do to 47.04 drilling hrs. Assembly unable to achieve sidetrack. Recommendations: PDC bit would improve ROP and save a bit trip due to hrs and K-revs Innovations and/or cost savings: No cost savings realized on this section. Mainly due to unplanned trip for bit. LMWD AAR Page 1 REV 2 L/MWD After Action Review Well: Walakpa 11 Hole Section: 6.125" Production Employee Name: Lucas Smith Date: 2-28-2012 What went as, or better than, planned: Surface detection was clear and with strong pulse amplitude. Difficulties experienced: ROP was not recorded during R100 due to connectivity issues between the database and PASON. Realtime data was not recorded at the beginning of Run 400 due to a dual computer hardware failure. SAG not utilized during R500 due to greater than expected inclination corrections. Recommendations: Innovations and/or cost savings: Pulser was stuffed and pulled in the pipe shed saving 2 hrs of rig time.
