We had that letter in our file. As I noted in my original message 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. Incases 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 • • Page2of3 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.

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.

The extent of the abandonment of this well in preparation for sidetracking it with Tofkat #1B will be by setting a cement plug ~ ~~-$ across the 9-5/8" casing shoe at 3,898' MD. The abandonment/kickoffplug will be set across the interval 3,800' - 4,400' MD. Cement plugging of the hydrocarbon-bearing zones will be achieved by setting isolation cement plugs as follow. Also, a densified cement plug will be placed across the 9-5/8" casing shoe for kicking off the Tofkat #lA sidetrack. The open hole cement volume will include 30% excess. Casing Shoe Plug 1. RIH with open-hole bridge plug on drill pipe to 4,400'. Set and weight-test bridge plug and unlatch from it. 2. With the bridge plug running tool located just above the bridge plug, place a balanced cement plug across the casing shoe (100' inside 9-5/8" surface casing shoe to 500' below shoe in 8-1/2" open hole) as follows: Pump 15 bbls Alpha Spacer with 1 gaUbbl surfactant 434B at same weight as mud.

Tofkat #lA (PTD # 207-173) Dear Mr. Seamount, Brooks Range Petroleum Corporation proposes to plug and abandon the open-hole portion of its Tofkat #lA 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 #1B will be submitted under separate cover. One cement plug is planned, across the surface casing shoe, is planned 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 interval and our plan to abandon them. The abandonment of Tofkat #lA will be accomplished as indicated on the attached wellbore diagram and P&A procedure.

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.

Interesting that three of the plugs did not set. Don't remember seeing that before, but it may point to incompatibilities with the OBM.

Form 10-403 must be submitted for the necessary plugging operation for Toikat No. 1 (207-173). It is understood, that this redrill is dependent on the outcome of Tofkat No. 1. 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. Cuttings samples are not required if samples were obtained in the Tofkat # 1. A mudlog is required for the redrill section. 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 surface casing to total depth of the Brooks Range Petroleum Corp. Tofkat #lA Permit: 208-028 redrill. If formation testing is planned, a Sundry Notice (Form 403) must be submitted in advance of the operations. 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. Failure to comply with an applicable provision of AS 31.05, Title 20, Chapter 25 of the Alaska Administrative Code, or a Commission order, or the terms and conditions of this permit may result in the revocation or suspension of the permit. When providing notice for a representative of the Commission to witness any required test, contact the Commission's petroleum field inspector at (907) 659-3607 (pager). Sincerely, Daniel T.

Cosal~si4n ~n~h~raga Dear Mr. Norman, C~c~i ~r Brooks Range Petroleum hereby applies for a Permit to Drill a si c oil exploration well from an ice pad located approximately six miles east of the village of Nuiqsut on the North Slope. Brooks Range plans to use Nabors Rig #27-E to sidetrack its Tofkat #1 well to delineate its discovery i_f that well proves successful. If Tofkat #1 proves to be unsuccessful in finding encouraging amounts of hydrocarbons, the rig will be moved to Gwydyr Bay area to drill Brooks Range's North Shore #3 well. The application for Permit to Drill the North Shore #3 is being submitted under separate cover. Our anticipated date for commencing drilling the Tofl~at #lA is March 15. The Tofkat #lA well will consist of a sidetrack of the Tofkat #1 wellbore with the kickoff point located at the shoe of the surface casing in the original wellbore. A simple build and hold 8-1/2" hole will be drilled to a bottomhole location near the edge of the presumed hydrocarbon accumulation and the sidetrack wellbore cased with 7" production casing. The well will be production tested after the rig has moved off the pad and then will be operationally shut down until pe~~ `ent,~roduction facilities are installed. ~ ~ S~ ~~ wc~,~, ~ s co Mss ~z~~~~ c~~ ~ ~~~ ~~s ~ ~ ~ ~ ~ ~~aP~c~- Please find attached information as required by 20 AAC 25.005 (a) and (c) for your review.

Offsetting well information indicates that pore pressure at TVD will be a maximum of 10.2ppg (or 0.5304 psi/ft). Calculations: 8-1/2" hole section MASP (pore pressure) _ (8200 ft) (0.5304-0.11) = 3447 psi i With MASP in the 8-1/2" open hole section is expected to be 3447 psi and the 5,000 psi BOPE system to be used will be adequate. Well Proximity Risks: The closest wellbore to this one is Oberon #llocated approximately 4.1 miles away so there is no anticipated interference expected between wellbores. Drilling Area Risks: 1. There is a remote possibility of encountering gas hydrates. If hydrates do occur, they will be treated handled by slowing down ROP, increasing mud weight and making slower bit trips. 2. There is little risk of H2S in the area, as none of the offsetting wells encountered any. However, as a precaution, the rig and mud logging units will have functioning H2S detectors. • ~ Disposal of Muds and Cuttings: All drill cuttings and waste drilling fluids will be disposed off in BP's grind and inject facility at Prudhoe Bay or in approved Class II disposal wells in Kuparuk Field. • Brooks Range Petroleum Corporation Tofkat No. lA CSG Design Safety Factors Burst Requirements for 9-5/8", 40 #, L-80, BTC surface casing: Max.

The Tofkat ice road spur will depart from the annual Alpine ice road and proceed south to the Tofkat ice pad location. An 8-1/2" "sidetrack" is planned to kickoff r at 4,000' MD / 3,010' TVD. The Production sidetrack interval will be drilled with a planned system mud weight of 10.0 ppg to 10.5 ppg to interval TD at 12,999' MD / 8,149' TVD using a combination of new and recycled VERSAPRO NT MOBM. A 7" liner is planned to be set at TD. 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 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: October 8, 2007 s ~- Brooks Range Petroleum Company Tofkat #1 A Sidetrack Project Summary Casing Hole TVD Mud Size Size MD ss Density Range (inl (in) Profile (ft) (ft) (ppg) 3,879 2,949 10.0 ~ 9.625" NA KOP KOP Recycled 4,000 3,010 VERSAPRO NT 10.0 (initial) (Leer) 8.5" 12,999 8,149 10(OtTD0.5 Recycled VERSAPRO NT Location North Slope Alaska Confidential 3 Date: October 8, 2007 Brooks Range Petroleum Company Tofkat #1 A Sidetrack Milling Casing and Production Interval Drilling Fluid System VERSAPRO NT Key Products LVT-200, IMG 400, Lime, VERSACOAT HF, VERSAWET, VERSAMOD, VERSAHRP, S-200, Brine 10.8 CaCl2 , MI WATE Barite Solids Control Shakers, Mud cleaner, Centrifuge Potential Problems Lithologic instability near the wellbore.

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.

The "sidetrack" production interval of the well will then by drilled using an 8-1/2" bit. This interval will be drilled with a planned system mudweight of 10.0 ppg to 10.5 ppg to interval TD at 12,999' MD / 8,149' TVD using a combination of new and recycled VERSAPRO NT MOBM. A 7" liner is planned to be set at TD. - 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. - 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 6 Date: October 8, 2007 ~~ Brooks Range Petroleum Company Tofkat #1 A Sidetrack Milling Casing Production Interval Operations - This interval will be drilled using an 8.5" bit to an expected interval TD of 12,999' MD / 8,149' 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 7 Date: October 8, 2007 Brooks Range Petroleum Company Tofkat #1A Sidetrack 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.

For purposes of this program, it is assumed the 7" production casing is set and perforated and the well is to be PTA'd.. Plug #1 (Hydrocarbon bearing interval inside 7" production casing ) Downsqueeze method: To reduce WOC time -set 7" 26# EZSV 50' above top perforation. Sting in and downsqueeze with a cement volume equivalent to fill cement from EZSV to 100' below the lowermost perforation. Unsting from EZSV and lay in 50' of cement slurry on top of EZSV. POOH several joints and pressure test EZSV (1,500 psig or 0.25 psi/ft multiplied by TVD, whichever is greater). POOH to surface casing shoe. Plug #2 (9-5/8" Casing Shoe Depth inside 7" 26#/ft casing) Displacement or Balanced Plug method: 100' of cement below the 9-5/8" casing setting depth to 100' above 9-5/8" casing setting depth inside 7" 26#/ft casing.: Plug #3 (Surface 9-5/8" 40#/ft casing and 7" 26#/ft casing) Displacement or Balanced Plug method:: With 7" casing cut and retrieved at 105' Seta 200' balanced plug from 100' inside the 7" casing stub and 100' above the 7" stub inside 9-5/8" casing with top of cement no less than 5' below surface. Plug #1: Downsqueeze method (Hydrocarbon bearing interval) 7" 26# EZSV set 50' above top perforation. Downsqueeze with a cement volume equivalent to fill cement from EZSV to 100' below the lowermost perforation + 50' of cement slurry on top of EZSV. For planning purposes -length of plug inside 7" 26#/ft casing is assumed to be 500'. Actual cement volume will depend on conditions at the time of plugging. Plug Slurry: 19.1 bbls - 94 sks.
