Tom Maunder, PE AOGCC From: Maunder, Thomas E (DOA) Sent: Friday, August 28, 2009 10:52 AM To: 'Amber Babcock' Cc: 'Bill Penrose'; Regg, James B (DOA) ~-~ " Subject: RE: 2008 Site Inspections Thanks Amber. We had that letter in our file. As I noted in my origiressage to Bill (text attached at end), the last item in our file was your email of August 22, 2008 regarding rescheduling the site visit due to weather and other issues. It appears that no information was submitted regarding the site inspection that was ultimately accomplished until your message of August 27, 2009. There appears to be a "gap" here and I will work to get a message out to those operators/contractors conducting site inspections. In this case, the 407 was submitted May 16, 2008 according to the document copy you emailed this morning. Although we did have an Inspector out there, I feel the operator/contractor should still submit a report of the inspection much like the protocol for BOP and safety valve tests. In cases such as this, the protocol I see as appropriate would be to submit the information attached to a 404. I will plan to get a message out outlining that protocol. 9/3/2009 Page 2 of 3 Regarding the other site inspections conducted at the same time, I suspect that information regarding the inspections of Tofkat or North Shore may also not have been submitted. You may wish to check your records. I will examine ours and get back to you. Call or message with any questions.

Brooks Range Petroleum Corporation North Shore and Tofkat Summer Clean-Up Work Field Activity Summary Submitted by: Amber Babcock, Fairweather E&P Services, Inc. August 26, 2008 The North Shore site was accessed by helicopter with two personnel. A vehicle was staged at S-pad with two additional personnel (due to weight restriction on the helicopter) that were later transported to the site. The clean-up crew picked up debris on and around the pad area. The helicopter transported 10 sling-loads of material to the vehicle staged at S-pad to include large timbers, one 3.5"diameter piece of tubing and several bags of miscellaneous debris. August 27, 2008 Equipment was obtained to cut the timbers and tubing to manageable sizes, to allow transport by vehicle to Deadhorse for disposal. A crew of three and equipment mobilized to S-pad and loaded the cut debris onto the vehicle. Two additional personnel performed stick picking of the ice road route. Approximately 50 helicopter landings were made along the route. The weather deteriorated midday and delayed operations from Noon until 5:00 PM at which time stick picking activities resumed. August 28, 2008 A crew of four personnel continued performing stick picking along the ice road route. Approximately 301andings were made along the route and at the pad area. Flight hours = 3.2. August 29, 2008 A site inspection via helicopter was performed by Gerald Nayakik with the North Slope Bureau, John Easton with the State of Alaska Department of Natural Resources and Chuck Scheve with the Alaska Oil and Gas Conservation Commission.

It doesn't appear to be a contamination issue with the OBM, rather the hole geometry. The hole angle is 60 degrees and we're seeing indications that the viscous pills and then cement plugs are slipping down the low side of the hole, swapping places. In particular, the viscous pills, being the same weight as the rest of the mud system is swapping with the cement, the cement going down the low side and the pill slipping up the high side, before the cement has time to set. In the plug we're trying right now (surface casing shoe), we've added calcium chloride to the cement as an accelerator and made our underlying viscous pill the same weight as the cement. In my mind, the mud downhole will be working at swapping with the viscous pill while the cement sets. I have high hopes for this method -we'll know when we try to tag the plug later today.

The interval to be abandoned is 6,120' - 6,306'. We laid a cement plug from 5,860' to 6,360' and waited 24 hours. When we went back in to tag, we found hard cement at 6,153'. The hard bottom was witnessed and approved by Chuck Scheve. We obviously need additional cement to cover the exposed hydrocarbon-bearing interval (6,120' - 6,153') and we intend to lay in sufficient cement to cover the interval 5,860' - 6,153' to complete the continuous plug. My question: Since we now have a hard bottom to set this supplemental plug on, can we set it then leave it without WOC and tagging up on it, instead moving up hole to work on Plug #3?

Tofkat #1 (PTD # 207-173) Dear Mr. Seamount, Brooks Range Petroleum Corporation proposes to plug and abandon the open-hole portion of its Tofkat #1 well. It is intended to plug the well back to the shoe of the surface casing then sidetrack the well to a new bottomhole location. The Application for Permit to Drill Tofkat #lA has been submitted under separate cover. Two open-hole cement plugs are proposed, one across the Kuparuk - Brookian Turbidite interval and one across the shallower Qannik interval as indicated on the enclosed wellbore schematic. The wireline and mud logs from this well have been reviewed with AOGCC staff for their concurrence on the cemented intervals and our plan to abandon them. The abandonment of Tofkat #1 will be accomplished as indicated on the attached wellbore diagram and P&A procedure. If you have any questions or require additional information, please contact me at 339- 9965 or Bill Penrose at 258-3446. Sincerely, BROOKS RANGE PETROLEUM CORPORATION ./ ~ G~ James R.

Tom From: Bill Penrose [mailto:bill@fairweather.com] Sent: Friday, February 22, 2008 9:48 AM To: Maunder, Thomas E (DOA) Subject: RE: Tom, 1. About 80 bbls of good cement were received back at surface during the cement job. 2. The csg test and LOT information are attached. Note that the casing test was conducted with water base mud in the hole and the subsequent LOT was conducted after the change-over to oil base mud. The resultant difference in the slopes of the curves offers an interesting demonstration of the different compressibilities of the two systems.

Please note that this permit authorizes drilling activities in the planned hole section only. A separate permit applications must be submitted to plug back or abandon and redrill new hole sections. This permit to drill does not exempt you from obtaining additional permits or an approval 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 Commission 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 Commission's internal use. A mudlog and samples are required for this remote exploratory well. All dry ditch sample sets submitted to the Commission must be in no greater than 30' sample intervals below conductor pipe and 10' sample intervals through target zones. At a minimum, openhole gamma ray, resistivity, and sonic or density porosity logs must be recorded from the base of conductor pipe to total depth of the Brooks Range Petroleum Corp. Tofkat # 1 Permit: 207-173 well. If formation testing is planned, submitted in advance of the operations. a Sundry Notice (Form 403) must be Operations must be conducted in accordance with AS 31.05 and Title 20, Chapter 25 of the Alaska Administrative Code unless the Commission specifically authorizes a variance.

Brooks Range plans to use Nabors Rig #27-E to drill this well. The Tofkat #1 will be directionally drilled to the west into a suspected hydrocarbon accumulation beneath and to the west of the Colville River. ~~v~~~~ If the well proves sufficiently promising once TD is reached, it will be plugged back and `~ ~w~©r .~. a sidetrack delineation well drilled. If the well proves a disappointment, it will be ~(i,~ ~~~ permanently plugged and abandoned without a delineation sidetrack. Neither of these ~~,,,,wwnn scenarios involves running production casing and testing this initial well. `'~v1 ~ (~1 The wellsite will be accessed via a +1/2 mile spur ice road off ConocoPhillips' planned Alpine ice road, the use of which Brooks Range has entered into an agreement with ConocoPhillips.

Offsetting well information indicates that the pore pressure at TVD will be a maximum of 10.2 ppg (or 0.5304 psi/ft). / Calculation: HASP (pore pressure) _ (8,200 ft) (0.5304-0.11) = 3,447 psi ~ With HASP for this well to be 3,447 psi, the 5,000 psi BOPE system is appropriately rated. Well Proximity Risks: The closest wellbore to Tofkat #1 is the Oberon #llocated approximately 4.1 miles away. There is thus no anticipated interference expected between wellbores. Drilling Area Risks: Hydrates: There is a remote possibility of encountering with gas hydrates. If this does , j occur, it will be addressed via control drilling, increased mud weight and additions of lecithin. Hydrogen Sulfide: The Tofkat #1 well will be drilled in the midst of a relatively densely-explored and developed province that has proved to be free of significant pre- development H2S down through the planned TD of this well. The Alpine field is immediately to the north, the Kuparuk River field is nearby to the east and quite a few exploratory wells have been drilled all around the location of the proposed well. See the attached map. i ~- The Tofkat #1 will test the Kuparuk River Formation and the Jurassic Alpine C Formation which are produced in the Kuparuk River field and the Alpine field, respectively, without original H2S. Further, most of the nearby exploratory wells drilled in the past penetrated these intervals with no noted H2S present. ~ As a standard precaution, the drilling rig and mud logging units will have functioning H2S detectors and the rig and camp will have emergency breathing apparatus for ~' evacuation, rescue and well shut-in contingencies. Disposal of Muds and Cuttings: All drill cuttings and waste drilling fluid will be disposed of at BP's grind and inject - facility at Prudhoe Bay or in ConocoPhillips' Class II disposal wells in the Kuparuk Field.

The Tofkat ice road spur will depart from the annual Alpine ice road and proceed south to the Tofkat ice pad location. A 16" conductor is planned to be set at 100' MD/TVD. The surface interval is planned to be a 12-1/4" hole drilled to a depth of 3,835' MD / 3,000' TVD at which point 9 5/8" surface casing will be run and cemented. The production interval is planned to be an 8-1/2" hole drilled to a final TD of 13,654' MD / 8,200' TVD and 7" production casing will be set at TD. The highest prognosed mud weight will be found in the production interval, with an expected mud weight of 9.5 and 10.7 ppg. As with all exploration wells some geologic uncertainty exists. Communicate with the rig team to determine what the actual needs of the well are. Remember the main purpose of the well is to gather information in a safe and environmentally sound manner. All decisions made concerning the integrity of the well should keep this in mind. Lost circulation may also occur in the final leg of this well. ECD's should be monitored closely. Contingency should be made to have extra volumes of drill-in fluids on hand prior to drilling ahead. Lost circulation material should also be readily available. Fluid and Drilling Concerns - Wellbore stability throughout the drilling phase of the operations. - Hole cleaning - Control of ECD's - Lost circulation -well control - Minimized torque and drag. - Good cement jobs. - Hole condition to allow logging operations. - Minimization and management of waste costs for the "drill cuttings" and associated fluids. Monitoring and efficient utilization of the trucks and gravel washer as required for this operation. Daily and interval summaries will be tallied and summarized for the end of well report. - HSE Location North Slope Alaska Confidential 2 Date: December 12, 2007 Brooks Range Petroleum Company Tofkat #1 Project Summary Casing Size in Hole Size in Profile MD ft TVD ss ft Mud Density Range 9.625" 12.25" r~ . 3 835 000 3 9.5 - 9.8 , , Spud Mud 10.0 (initial) 7" 8.5" 13,654 8,200 10.0 - 10.7 (at TD) VERSAPRO NT Location North Slope Alaska Confidential Date: December 12, 2007 i Brooks Range Petroleum Company Tofkat #1 Surface Interval Drilling Fluid System Spud Mud Key Products MI Gel, GELEX, Caustic, MI WATE (Barite), DRISPAC PLUS SL, DRILLZONE, SCREENKLEEN, Solids Control Shakers, Mud Cleaner, Centrifuge Potential Problems Large gravel sizes can cause hole-cleaning problems.

Higher concentrations would be added if required, but results need to be carefully monitored and reported. Location North Slope Alaska Confidential 4 Date: December 12, 2007 ` Brooks Range Petroleum'Company Tofkat #1 Surface Interval Treatment Procedures - Gravel can cause hole-cleaning problems. If larger than normal gravel is encountered, be prepared to increase funnel viscosity from 250 - 350 sec/qt. Have GELEX available for an immediate response to this issue. - Mix the surface interval "Spud Mud" using the coldest water possible. Due to expected flow rates (and the associated temperature increase resulting from the flow rate), the temperature of all water added to the system should also be maintained at as low a temperature as possible. - Avoid washing out the shoe of the conductor pipe by drilling to 150' using a reduced flow rate 500 - 600 gpm) and then maintain flow rates as per the "Virtual Hydraulics Hole Cleaning Model" and stay below an effective 100 ft/hr ROP to ensure hole cleaning. Reduce pump rates immediately if packing off occurs. - Drill ahead. Adjust rheology, ROP, pipe rotation speed (60 - 80 rpm minimum), pipe running speeds and pump rates as needed to balance hole cleaning and ECD. - Drill ahead watching for wellbore instability problems. Any fluid weight adjustments should be performed in 0.1 0.2 Ib/gal increments if absolutely necessary. - Sticky clays in the permafrost and also in the zone below the permafrost can slow ROP from bit and BHA balling. Add DRILZONE (in 0.25% increments) and Nut Plug (as allowed by MWD tools) to minimize clay to metal sticking only if needed. - Add LoToRO if needed up to a concentration of 3% v/v. Ensure that hole cleaning is adequate prior to any lubricant additions are made to the system. Additions of lubricant over this recommendation concentration should be carefully considered. Do not use lubricants to mask the affects of hole cleaning or other problems that may be manifesting themselves as torque and drag issues. - Once the permafrost has been drilled, additions of small amounts of Mix II to lower fluid loss may be required. - Once the permafrost has been drilled begin to increase the proportion of polymer additions, while reducing the quantities of MI Gel that are used to maintain the rheology of the fluid. - Hydrates may be encountered. Determine severity of any influx and weight up as needed to maintain proper well control. See "Hydrate Issues enclosure". - To help ensure good cement to surface after running the casing, and if practical for existing hole conditions, condition mud to a funnel viscosity of +/_ 55 - 100 sec/qt (YP at 15 - 17) prior to cementing the casing. Have water on hand to ensure the desired rheologies can be achieved. Location North Slope Alaska Confidential Date: December 12, 2007 • Brooks Range Petroleum Company ~ Tofkat #1 Surface Interval S.C.E. Operation Standards Shakers- • LO/TO Shakers • Replace all decking rubber on the Derrick shaker beds. This will allow for optimum screen performance during drilling operations. It is important to develop a good preventive maintenance schedule which includes replacing the decking rubber before it becomes a performance related issue. • Install XR Magnum screens (84 - 110 mesh). Ensure screens are properly tensioned, per M-I Swaco's best practice suggestions. Spray down new screens with fresh water before operating the shakers. • As fluid shears, screen up as necessary to higher mesh screen sizes. • Ensure jacking system on the Derrick 48 HI G or equivalent shakers enables the fluid to flow to the center of the screens, adjust and lock as necessary. Centrifuge- Surface interval requires a greater through put during most operations, which require the centrifuge to run at a lower speed (2,500 - 1,800 rpm), high differential as well. This setting allows the centrifuge to process more fluid and discharge more cuttings. With the lower rpm's the cut point is reduce from 3 - 6 micron cut to approximately 6 - 10 micron which gives up cut point but processes more fluid. Swaco recommends and stands behind the suggestion to run the centrifuge at the lower speeds during the upper sections of hole. General- • Proper apex size on the de-sitter during this section will greatly improve the performance of the centrifuge and overall solids control performance of pit system. Drilling conditions may dictate several apex adjustments, close supervision of mud cleaner will be highly rewarded. Location North Slope Alaska Confidential 6 Date: December 12, 2007 Brooks Range Petroleum Company Tofkat #1 Surface Interval Drilling Concerns - Lithology through this zone is a composite of pebble conglomerate and sand in the upper intervals with intermittent clay matrix. Carbonaceous material and coal may be noted. Based upon work done on previous exploration wells, a gel based spud mud is recommended for the surface interval. Initial viscosities of 150 - 175 sec/qt should be maintained through the permafrost. 9-5/8"" surface casing will be set and the cement will be pumped in a single stage to surface. - Gravel sizes can cause hole-cleaning problems. If larger than normal gravel is encountered be prepared to increase funnel viscosity to +175 - 200 sec/qt. - Sticky clays in the permafrost at and also in the zone below the permafrost can slow ROP from bit and BHA balling. If needed add DRILZONE (at 0.5 - 1.5%) and Nur PLUG M (as allowed by MWD tools) to help clean and clear the balled bit. - Use as much cold water as possible for the initial make-up and for additions made to the mud system during the surface drilling operations to help prevent permafrost thawing. Try to keep flow-line temperatures of 60°F or less while drilling this interval. - Maintain low flow rates for the initial 200' of drilling to reduce the chance of washing out the conductor shoe. - Swabbing in the clays may also be a problem. Maintain or slightly increase mud weight (0.1 ppg) and continue additions of surfactant at 15 to 30 gallons per hour and wiper runs through the surface interval may be necessary to clear the wellbore of the problem clays. DRILZONE or ScREENKLEEN maintained at 0.5 - 1.5% is also recommended to help with clay related issues. - To help insure good cement to surface after running the casing, condition mud to a YP of at least 25 - 30 prior to cementing the casing. Do not lower the YP beyond 25 to avoid trouble with sands that may be found on this well. Use water sparingly and ensure proper solids control equipment utilization is being observed to reduce the over all haul-off costs for this well. - Although a low potential risk, hydrates may be encountered (particularly at depths below the permafrost). Observe good drilling practices to determine severity of any influx and weight up as needed to maintain proper well control. See "Surface Hydrate Issues"enclosure for further information. Location North Slope Alaska Confidential 7 Date: December 12, 2007 • Brooks Range Petroleum Company Tofkat #1 Surface Interval Operations Recommendations Spud mud will be mixed on the rig or at M-I Swaco's Prudhoe Bay mud plant once the rig is spotted over the well. Use as much cold water as possible for the initial make-up and for additions made to the mud system during the surface drilling operations. - Drill ahead maintaining volume as needed. - Maximum fluid weight is planned to be 9.5 - 9.8 ppg for this interval. - Run all solids control equipment. Run 84 - 110 mesh shaker screens to maintain a moist discharge for enhanced solids removal. Add drill water below shaker to avoid washing unwanted solids back into the active system. Watch for "excessively wet" cuttings and change screens to a larger mesh should this occur. Minimization of "excessively wet" cuttings sent to Grind and Inject for disposal is a major cost reduction factor. - Lower API fluid loss with DRISPAC PLUS SL (or Poly Pac Supreme UL) as needed to maintain hole stability. - To control rheology additions of CF DESCO II may be needed. - Add DRILZONE or ScREENKLEEN (at 0.5 - 1.5%) and Nut Plug (at 15 ppb) to reduce bit balling in the clay sections if needed. DRILZONE at 0.5 - 1.5% may also be used to help with any clay issues. - If hole conditions allow, let the YP drop to 25 - 30 (no lower than 25) prior to cementing of the casing. Allow surface mud volumes to fall during the later stage of this interval to minimize waste fluid disposal costs. - Run and set the casing as per program. Treat the chase fluid and drill out mud for the upcoming cement drill out. - Upon drill-out of the surface casing shoe, treat any cement returns with SAPP, Sodium Bicarbonate, and PH-6 as needed.

Operation Standards: Shakers- • Inspect decking rubbers, c/o as necessary. • Install XR Magnum screens (175-210 mesh). Ensure screens are properly tensioned, per M-I Swaco's best practice suggestions. Spray down new screens with fresh water before operating the shakers. • Set counterweights to 90% (7.8 G's) for optimum performance. • As fluid shears, screen up as necessary to higher mesh screen sizes. 210 mesh is optimum to reduce sand sized particles. • Ensure jacking system on ALSII shakers enables the fluid to flow to the center of the screens, adjust and lock as necessary. De-Silter- • Ensure cuttings trough bypasses shakers, and goes into cuttings ditch. Failure to do so will allow small particles to enter right back into system through the flow line shakers (84-110 mesh screens). • Install 3/8" Apexes. • Ensure that "feet of head" gauge is available at the De-Silter, not the pump. • Ensure that De-Silter feed pump can achieve 95' of head. CRITICAL! • Monitor discard, change apexes as necessary to improve solids content in mud (it may be determined that 3/8" apexes can be installed if cuttings in the system happen to be finer than presumed) • Discard should be 2-3 ppg over feed weight. Centrifuge- Production intervals generally call fora "high-speed" centrifuge, which is rotating at approximately 3200 rpm's. This allows the centrifuge to make the 3-6 micron cut, and eliminate a percentage of the "ultra fine" cuttings from the fluid. Through put must be decreased while running the centrifuge at 3200 rpm's, since there is a greater risk of "packing off' the centrifuge back drive and auger. Swaco would also suggest installation of amp meter on the back drive motor which will allow the operators to monitor the feed rates by knowing how much torque the back drive motor is receiving while trying to discharge the cuttings. Refer to mud man for solids information to determine speed and feed rate of centrifuge. Continual processing at low feed rates will yield better results than shutting centrifuge down and starting it up. Slow feed rate down to maintain an acceptable weight if needed. Location North Slope Alaska Confidential 10 Date: December 12, 2007 Brooks Range Petroleum Company Tofkat,#1 Production Interval Considerations - Ensure that the fluid properties are maintained to provide the best possible hole cleaning. Maintain mud weights as per drilling program guide lines and ensure that rheology is optimized to reduce ECD's to a manageable level while drilling. Monitor for any fluid losses and flow back closely. - Control the ROP and flow rates as needed to avoid inducing a breakdown of any formations. Reduce pump rates immediately if packing off occurs. Pump high viscosity weighted sweeps and ream carefully to clean the hole before proceeding with further drilling - Adjust rheology, pipe rotation speed, pipe running speeds and pump rates as needed to balance hole cleaning and ECD. Use good drilling and tripping practices. Break circulation slowly -Reduce pump speed 15 to 20% while reaming down. - As an exploration well, pore pressure uncertainty also exists. Use all means possible to evaluate well conditions to determine if fluid properties are in line with the needs of the well. - SOLTEX may be required for shale stabilization prior to and throughout the HRZ. - Monitor and record drilling parameters on each connection and before and after any lubricant additions. - Upon reaching TD watch the bottoms-up cuttings closely. If the well does not readily cleanup or if there are any excess of torque, drag, pick-up or slack-off weights pump a second high viscosity/weighted sweep and observe bottoms up again. - Establish good hole conditions for any logging and testing that may be performed. - Fluid deliveries, fluid transfers, and cuttings disposal issues will be tracked on a daily basis. Location North Slope Alaska Confidential 11 Date: December 12, 2007 i • Brooks Range Petroleum Company Tofkat #1 Production Interval Operations - This interval will be drilled using an 8.5" bit to an expected interval TD of 13,654 MD / 8,200 TVD. Care should be taken to monitor all drilling criteria to ensure that best drilling practices are being observed. - Maintain low gravity drilled solids to below 6% with solids control equipment and dilution. Use the MI Solids Van to supplement rig equipment, if needed. - Use Virtual Hydraulics ECD predictions vs. PWD actual values to appraise hole cleaning and hole conditions. If possible do not allow actual ECD's to exceed 0.5 ppg over predicted "clean hole" ECD. - Drill to interval TD and circulate the wellbore clean (3 - 4 bottoms up may be needed) in preparation for logging and testing. - While drilling monitor the interval carefully for losses or gains. - Log and/or test the well as per program. - Plug back or complete as per program. Location North Slope Alaska Confidential 12 Date: December 12, 2007 Brooks Range`Petroleum Company Tofkat #1 Surface Interval Hydrate Issues Use the following guidelines to help minimize the effect that any hydrates which may have to the drilling operation. • Add 2 ppb Lecithin to the mud prior to drilling into the zone below the permafrost. CF DESCO II may be - used to adjust rheology after the Lecithin additions are made. • Weigh the mud at both the possum belly and at the suction pit using pressurized and regular mud balances to determine the amount of gas that has become entrained in the mud. • Maintain the fluid at below 60°F if possible. • Minimize circulation time to reduce hydrate thawing. • Watch both drill rates and flow rates and make adjustments as needed to help diminish any problems that the surface equipment may have in handling the fluid and cuttings while circulating out any hydrates. • Weight up prior to drilling out of the permafrost. Watch the rate of depletion of the hydrates and increase the weight as needed to control the gas breakout from the hydrates. Barite Sag Concerns Barite Sag (a reduction in the MW out due to the dynamic and static settling of barite) is a potential drilling hazard while using weighted fluids. Although this well is designed for a mud weights below -11.5 ppg unexpected conditions may make additional weight ups or lubricant additions necessary. Both of these changes may contribute to a more likely chance of barite sag issues. Barite Sag is also aggravated by circulating at low rates for extended periods of time or while tripping with drill pipe or casing. As a consequence, if it becomes necessary to circulate at reduced rates, it is recommended that the pit watcher weigh and record MW out using a pressurized and un-pressurized balance every 15 minutes. Trips and casing running should also be closely monitored for indications of barite sag.

Date: January 10, 2008 Tofkat-Ol well hydrates/ shallow gas assessment from Seismic: Back round: Investigation of seismic data for indications of potential anomalous high pressure zones is a requirement of the AOGCC Regulations. In practice, the only well to have experienced uncontrolled flow of shallow gas is the Cirque #1 well, which blew out in 1991 when it encountered shallow hydrates at 1200' feet md. Cirque #1 is located approximately 11.5 miles southeast of the proposed Tofkat-1 location (see Figure 1). There were no recordable drilling incidents with any of the nearby wells in the area (Oberon #l, Nanuks #l, #2 and #3, Clover A, Atlas #1, Cronus #1, Colville River #1, and Berschrund #2). ). John Buggenhagen conducted Shallow Hazards Analyses on both Oberon #1 and Titania #1, using their Nanuk 3D seismic data: he found "...no apparent shallow hazards or large pressure anomalies at the proposed Oberon #1 and Titania locations." Our surface location is several thousand feet east of CPAI's planned locations, so we have reviewed 2D seismic data in our possession for indications of Hazards. Due to their composition, gas hydrates are not detectable on conventional seismic amplitude displays. Seismic compressional velocities in hydrates are very. similar to the ice velocities in the permafrost (>10,000 ft/sec). Any amplitude or attenuation anomalies associated with hydrates are from free gases which are just below the base of the hydrates ~ (Bob Hunter, verbal communication). Based on logs from the Oberon #1 well, the base of the permafrost is at approximately 1160 ft which equates to approximately 280ms on the seismic data. The base of the permafrost is poorly imaged on seismic due to its transitional character. ConocoPhillips investigated 3D seismic data at the Cirque location for shallow anomalies that could correlate with and indicate the risk of the gas which that was subsequently encountered in Cirque #1 -they were unsuccessful (Memo from John Buggenhagen to ~ Laurie St. Aubin and Mark Chambers, AOGCC Oberon #1 Well file). This conclusion makes reliance on seismic detection of shallow hazards uncertain at best. Our review of available seismic data is described below. We believe that following prudent drilling practices (careful mud volume monitoring; avoiding quick trips out of the shallow hole) based years of North Slope drilling experience, are our best way to minimize this risk.

Figure 2 is a zoomed in map showing the Tofkat-1 location along with the nearby 2D seismic data that Brooks Range Petroleum has licensed. Highlighted in red are the two nearest seismic lines to the Tofkat-1 surface location, lines WKE92-07 and SK81-12. Figure 3 shows a very zoomed in view of the Tofkat-1 surface location along with the same two seismic lines and labeled section numbers. Several near by lakes can be seen out lined in blue along with the main channel of the Colville River. Figure 4 shows a migrated full stack display of seismic line WKE92-07 which was recently reprocessed. The vertical static busts in the line relate to the disruption of the ray paths due to shallow lakes in the area. Also shown on the line in Figure 4 is the well tie for the Colville River-1 PB well, as well as the approximate base permafrost seismic pick. A possible shallow bright can be seen at CDP 2560 just below the base of the permafrost. Figure 5 is the relative amplitude display of line WKE92-07. Absent are any apparent '~ shallow bright spots associated with free gas in or below the base of the permafrost in the vicinity of the surface location of Tofkat-1. Figure 6 is the same line with the final migration velocities displayed. The Tofkat-1 surface location is projected onto this display which shows a lowering of the migration velocity in the vicinity of the Colville River crossing. Figure 7 shows the shallow tomographic velocity profile for line WKE92-07 derived by analyzing the first break arrivals on the shot records. The tomographic velocity profile for the first thousand feet of section does show a similar velocity reduction under the Colville River crossing. Figure 8 shows the corresponding tomographic ray path model used to derive the tomographic velocity model shown in Figure 7. Figure 9 shows the migrated full stack display for line SK81-12. No apparent bright spots are detectable in or near the base of the permafrost section. When all the data is reviewed together, there appears to be no apparent shallow / drilling hazard in the vicinity of the Tofkat-1 surface location. Shallow Fault Analysis: No apparent shallow faults are imaged on either of the two seismic lines. ~ 5/!)L.St c~ri, Srtitef!)/,,q~Glt~r«4;z..tki;ka 4V5!1! !`ej 9(I'.239.94fi? ri;x: ~_~?..~S~.>9(1 Tofkat-1 Surface Location Figure 1 Tofkat-1 Area Base Map with Seismic Line Locations Base A~1a4? - ' ...., ~. r _ ~ ~ _ _ .~ . ~ ~: -- -y - _ - J ~ j ~ - ~ -~~ t: ,u .~ I ',S,.; ~t. i ., i < ' ~ ,.:.. t F ~. _.. ,A S-- <.-_ ..ems _ _, .. _ , i ~ .. ~ ~ ~~ ~ _ i ~, ~: ~ ~' '' _.... , ~ ~ ~ - - , ~ ~ + 111 r. ~ '~ i `I -. - '.. r ` ,. , A: ~'4 j f. ~ ~; - ..i-...a - J - ~ ~~ ~ ~ ~ °' e ~~iL, V~ ; ' BRPC Group ~~ 1 ~ '~~ ~' ~ ~ ~ i r-~--1--~----'-' ~.,~ ,~:~, leases shown in i, ~-°~L - ~ _ ~ ~ ~_~~~~=~' . _ i .. yellow.

The logging program will consist of GR/Res/Neut/Dens in the 8-1/2" hole and a dipole sonic run from TD to '' surface.

I just got back in the office myself. I'd like to get the PTD done and out, but I need the following: 1- Information on shallow gas hazards over the location. Seismic, etc.; 2- Your BHP is on the PTD as 7200 lbs. Is this correct? Looks high even at those depths. 3- You did not include your logging program. We will require shallow porosity logs for calculating shallow zone salinities. If you can get this information to me in the next day or so, I'll get the PTD out for you.

These locations are less than 500' from the lease line, but since we own both leases, we won't object. If successful, we plan to sidetrack to Tofkat #lA, which will bottom cleanly in DL390676. Both locations are on 2D seismic lines which we own, which explains why at least one is so close to a lease line.

Introduction: Brooks Range Petroleum has requested that the Sonic Scanner data acquired on 4-Mar-2008 be re-evaluated for deviation affects due to the high angle of the drilled well. Compressional and shear sonic values are needed to be corrected back to the equivalent for a vertical well for AVO processing. 2. Interpretation: 2.1 Inputs: Sonic Scanner data was acquired on drill-pipe and down-logged on 4-Mar-2008. The method of acquisition caused some limitations to the data quality due to improper centralization in the borehole. Additionally due to the drill pipe conveyance, GPIT (orientation) data was not acquired with the tool. Since the tool was logged down, calipers were not run, so no borehole ID information is available. Sonic Scanner data was acquired in three sections with about 100 ft of over-lap. Final processed data was depth matched to the ARC gamma ray and spliced into a continuous file, as requested by customer. LWD data was acquired while drilling including ARC (resistivity) and ADN (density and porosity). Final provided LAS combines processed sonic and LWD. There is a general degradation of data quality above 6500MD. This may be due to higher decentralization or degradation of the borehole, rugosity and wash-out. Neither factor can be quantified with the acquired data- set. 2.2 Technique: Sonic Scanner is part of the Schlumberger wireline Scanner family of e-line measurement tools. Sonic scanner has a longer azimuthal array than other acoustic tools, 13 stations and 8 azimuthal receivers at each station. Sonic scanner is fully characterized and acquires a wide frequency spectrum with higher signal-to- noise data than previous sonic tools. Deviation correction would normally be computed from solving for the elastic moduli components, output from the 3D Anisotropy modules, and combined with bulk density, to be able to back out the horizontal and vertical velocities. C44 = ρV2SV C66 = ρV2SH C33 = ρV2PV C11 = ρV2PH CXX: elastic moduli ρ: density V: Velocity S-Shear P-Compressional V-Vertical H-Horizontal Limitations: This data set specifically is of limited data quality, since the Sonic Scanner was logged on drill-pipe tripping in the hole, and was not properly centralized. Due to the drill pipe conveyance, GPIT (orientation) was not run; tool orientation was recomputed from the relative bearing and LWD survey. Eccentraliztion causes contamination of the waveforms; specifically eccentraliztion will cause monopole waves that corrupt the dipole signal. Shear waveforms were filtered to remove late time signal to cut reduce the contamination affect. Even with filtering the processed 3D moduli were too noisy for use. Assumptions: General assumptions were applied to still allow a correction to the equivalent vertical measurement. The shear wave is dispersive, allowing direct measurement of the fast and slow shear waveforms. Fast and slow shear measurements were of fairly high quality from the anisotropy processing. The fast shear measurement can be assumed to be Shear Vertical (SH), related to C66. The slow shear measurement is assumed to be Shear Horizontal (SH), related to C44=C55. Since the deviation is consistent throughout the logged interval within 2 degrees, there is no change in deviation angle to account for, only a variation in formation Sonic Anisotropy Error!

Since the deviation in the well path was constant, this anisotropy flag was used to correct the compressional velocity to the equivalent to vertical with a fixed ratio of 9%. Final processed results were compared to off-set wells and appeared to be consistent. 3. Conclusion DTCO (delta-T compressional), DTSM_SLOW (delta-T shear), and DTSM_FAST (delta-T shear) were processed with GeoFrame4.4 BestDT from the acquired waveforms. DTSM_SLOW is assumed to be Shear Horizontal (related to C44 = C55), measured anisotropy was converted to a unit less blocked curve and applied as a correction to the compressional measurement DTCO. DT is the anisotropy shifted DTCO. The final processed data was depth matched to the ARC gamma ray and combined with all available LWD data in one final LAS file with the following curves: DTCO Delta-T compressional (uncorrected for deviation) DT DTCO corrected for deviation (compressional horizontal) DTSM_FAST Delta-T of fast shear waves DTSM_SLOW Delta-T of slow shear waves (assumed as shear horizontal) DTST Delta-T of Stoneley waves PR Poisson’s ratio (from DT and DTSM_SLOW) VPVS Compressional to shear velocity ratio (from DT and DTSM_SLOW) FLAG Anisotropy flag SLOANI Slowness based anisotropy TIMANI Time based anisotropy XENEDIF Minimum and maximum cross energy differences GR_EDTC Gamma Ray - Sonic Scanner TENS Tension from Sonic Scanner run RB Relative Bearing of Sonic Scanner GR_ARC Gamma Ray - ARC A28H Attenuation Resistivity 28 inch spacing at 2MHz A34H Attenuation Resistivity 34 inch spacing at 2MHz A40H Attenuation Resistivity 40 inch spacing at 2MHz P16H Phase shift resistivity 16 inch spacing at 2 MHz P22H Phase shift resistivity 22 inch spacing at 2 MHz P28H Phase shift resistivity 28 inch spacing at 2 MHz P34H Phase shift resistivity 34 inch spacing at 2 MHz P40H Phase shift resistivity 40 inch spacing at 2 MHz DRHB Bulk density correction, bottom DRHL Bulk density correction, left DRHR Bulk density correction, right DRHU Bulk density correction, up PEB Photoelectric factor, bottom PEL Photoelectric factor, left PER Photoelectric factor, right PEU Photoelectric factor, up ROBB Bulk density, bottom ROBL Bulk density, left ROBR Bulk density, right ROBU Bulk density, up ROP5 Rate of penetration averaged over 5 feet RPM_ADN ADN rotational speed TAB_ARC Time after bit, ARC resistivity TNPH Thermal neutron porosity Sonic Anisotropy Error!
