Nothing additional is in either well history. Would we send an inspector out again, or consider these sites cleared?

Supervisor FROM: Lou Grimaldi SUBJECT: Location Clearance inspection Petroleum Inspector Gubik #4 Anadarko Petroleum Co. PTD #208 -206 Exploratory Thursday, July 23, 2009: I made an inspection of surface condition for location clearance on Anadarko Petroleum's exploratory well "Gubik #4 ". I met Federico Lier (Anadarko Geologist) at Air Logistics' heliport in Deadhorse and flew to three locations today including this one. The surface texture of the tundra was extremely uneven with deep "tuck's" and I opted to make a visual inspection from the air rather than walking the ground. The pilot made several low passes during which I saw a superior job of cleanup had been performed without any trash evident. There is a significant depression (2' -3' approx) in the cellar area with what appears to be mud mounded up around it. The depression is most likely from subsidence in the cellar fill. Possibly knocking the edges into the depression would give this a natural appearing contour. Mr. Lier explained that the substance on the ground was natural and not drilling mud. I recommended that he garner a sample for determination. If the depression and the mud circumstances are approved I feel no further action is required to remediate this site.

Wolf Creek -4 and Gubik -4 penetrate topset Brookian reservoirs, and Chandler -1 drilled through topset and bottomset Brookian reservoirs. Anadarko plugged the wells and is analyzing results to determine the area's commerciality. No pipeline exists to transport gas. Anadarko is operator with 33.34% working interest in 1.9 million acres east of Umiat and just east of the National Petroleum Reserve- Alaska. Petro - Canada and BG (Alaska) E &P Inc. hold the other interests. Anadarko has previously estimated a resource of 2 -10 tcf of gas on the lands. The state has proposed to build a 90 -mile road from the Dalton Highway to Umiat on the Colville River. Exploration near Umiat dates to the 1940s.

What appeared to be a chunk of cable in the photos sent earlier, was actually some soft line. That and some scraps of wood were removed before backfilling began. One shot is of the jaws working on the original spoil pile to refill the hole. One last shot I tossed in shows only a corner of the mound and camp, but if you look just left of the edge of the camp, you can see the old Navy standard derrick in the background. Hope that this meets with your approval. I'm heading out early in the morning and hope to see you again soon. Thanks, Don E.

In picture "Gubik 4 P &A Marker(1) 4- 11- 09.jpg" there is what looks like a piece of wire looped out of the side of the hole, ✓ please try to remove that (or as much as possible). The only items that may be buried are small pieces of unstained wood and not very much of that. Other than that item I feel it would be OK to go ahead and fill in the hole. Avoid burying large chunks of ice as they will cause a depression in years to come and may require a return visit. Please take some pictures at various levels of hole fill to document you are not burying anything (like one of us). I do regret not getting to visit with you this season. Thank you for your attention to this matter and send the fill pictures at your first convenience.

For reference, the cellar CMP beside the hoe is 10' tall. In the photos, you can see the imprint of the corregations in the dirt /ice at the bottom of the hole. The top of the pipe, where the abandonment marker is welded on is about 18 inches above the bottom of the old cellar. The ice pad is 2 feet to 2.5 feet thick. Therefore the top of the P&A marker is about 6' below tundra line. 4/13/2009 • Page 2 of 2 I'll give you a call in a few minutes to see if we can proceed with filling the hole with the spoil from setting the cellar.

If the pictures show definitively that the cutoff is far enough below tundra can we waive witness of this? This will take an inspector out of Deadhorse for the good part of a day (at least). 1 also advised Don if we were not there to take pictures while they were filling in hole to preclude suspicion of burying junk.

Commissk; Anchorage Mr. Maunder, Attached for AOGCC approval is our Application for Sundry Approval to plug and abandon the captioned well. Plugging operations are to commence immediately following the current open hole logging operation, and therefore, we respectfully request expedited approval. The plugging procedure and wellbore diagram are attached. Please note that when cementing our 7" casing we did not circulate cement to surface — although the spacer was circulated to surface. We believe that the top of cement in the 7" x 9 -5/8" annulus is near surface and we plan to confirm that depth with E -Line logs. Then the 7" casing will be cut and recovered accordingly. If you have any questions or comments, please direct them to Skip Coyner at 907 -273- 6305 (ofc), 907 - 440 -6647 (cell).

I am sure that your company operates under the belief that a safe operation is more profitable in the long run and we must all do what we can to ensure that everyone gets on the plane the same way they got off of it (hopefully smiling more). These things happen from time to time and although I have been on this side of the regulatory fence for awhile I remember the pressures (most self imposed) to perform when I was on the service side. I have since spoken with the individual in question and been assured that this will not happen again. I choose to accept this person at their word but feel that your policies properly enforced should preclude this from recurring. A suggestion that comes to mind is checking in and out of locations when traveling with the time being noted. With a good average travel time known for each stretch of road, random checks of travel time will identify who is exceeding your posted speed limits. This could also alert you to missing personnel that may be in trouble and out of communication. As I said this is only a suggestion and you may have some equivalent program in place. I will be insistent on carrying my arctic gear at the ready. I also consider packing a truck so tightly that visibility is reduced or making it difficult/impossible to don your gear should be avoided. I am in the unique but favorable position to make things happen for myself on location that your company /service personnel may not be able to "enjoy ". It should not be this way, if you need to move 4 people and their gear it may take two trucks or two trips to do it safely, I favor the two truck method as it gives you a backup. We have to be careful of the risk factor being unduly influenced by the chance factor. I am satisfied with your response and consider the matter closed from my perspective. I am copying my supervisor James Regg on this e-mail as I am bound to report situations I. consider unsafe. He or someone else may have more questions. Thank you for your prompt attention to my concerns, Lou Grimaldi From: Kelly, Brian [ mailto :Brian.Kelly @anadarko.com] Sent: Sat 3/14/2009 5:02 PM To: Grimaldi, Louis R (DOA) Cc: Bowen, Kim; Freemyer, Steve; Alaska.DrillingOpsMgr Subject: RE: observations at your facility Mr. Grimaldi, first of all thank you for bringing these safety concerns to my attention. We take any safety concern raised at one of our locations very seriously. To that end, I am copying the General Manager for Alaska Operations, Mr. Kim Bowen (my direct report) and Anadarko's EHS Manager in Houston who oversees Anadarko's Alaska and International operations, Mr. Steve Freemyer. I am also copying our drilling operations manager. I will address your concerns as two separate items and detail mitigating measures we currently have and will consider based on suggestions for improvement. In order to constantly improve our safety programs, we review our policies and programs annually and make revisions when necessary. Speeding on Ice Roads 3/16/2009 RE: observations at your facie • Page 2 of 3 We have a 25 mph speed limit on all 71 miles of our ice road and crews are informed of this upon check in at our staging pad if they drive from Deadhorse and at the camps during weekly all -hands safety meetings and daily pre job safety meetings. We currently employ a security guard who's purpose is to assist with journey management and monitor and enforce this speed limit on the road system. In addition, every individual who comes on our job site has the authorization to stop work (or driving) if he or she feels it is unsafe to do so - no questions asked. This is standard policy on the north slope. One thing we can do immediately is give our security guard the authority to hand out speeding tickets. In addition, if there is a formal complaint such as yours, this will also count as an offense. A contractor or employee will get one warning for first offense, a ticket for second offense and recommended to take a safe driving class. If a third offense happens, the contractor or employee will be suspended from driving on our ice roads. The safety department will keep track of formal complaints or driving tickets issued to contractors or employees. Arctic Gear With regards to arctic gear in the pickup cab, if there are three or less people in the pickup every attempt is made to squeeze the gear into the cab. If there are 4 passengers in a pickup, some arctic gear would have to go in the back and I understand there were four people in your vehicle. This brings up a great point about providing crew vans or larger personnel carriers for moving crews from on location another without having to use a pickup truck. At our Wolf Creek location we did have a bus that we used to move crews from the well site to the airstrip. Unfortunately, at this location we do not have a bus or larger vehicle currently available. I do know these are hard to come by on the north slope, but we will look into obtaining a crew van or larger vehicle for moving personnel from one location to another. Next season we will add more vans to our fleet of vehicles for moving folks around. I hope I have addressed your concerns. Feel free to contact me or my managers on Monday to discuss further if you would like more information.

I had the opportunity to visit the Gubik #4 location last week for the function/performance test of the Diverter system on Doyon/Akita rig #1. The test of the rig's equipment went very well and I saw no problems or issues with the rig or it's components. I have thought long and hard about this message and feel some conflict in passing this information along but am morally obligated to do so. I witnessed one of your people driving what I consider to be in a completely wreckless fashion. He was driving at a very high rate of speed through some hilly curving ice roads. I have driven ice roads for better than 25 years myself so I feel I am a good judge of road conditions and he was well in excess of the acceptable speed that should be allowed. I realize that no one can accurately predict what will happen in the future but the chances are better than even that this type of driving will end up with him going off the road or running head -on into someone coming the other way. It is not just his life that is in danger. One other item of concern is the lack of arctic gear carried in the vehicles. I carry mine at all times and require that it be kept inside the vehicle so it is there and warm if needed. When I was leaving the Gubik location I was forced to place my gear in the bed of the pickup I was riding in. I don't make your rules so what you do with this information is up to you but I will not 3/16/2009 RE: observations at your fac, • Page 3 of 3 do that again. If you get in a accident your gear can be thrown from the pickup and lost or blow out of the back. If you roll your truck you may not be able to get to it. Putting on arctic gear that is at -40 already will not save your life. I will not preach to you or your company anymore and I will wait to hear your reaction and plans to remedy these situations, I will pass this information on to my superviser Monday morning. I leave the North Slope Saturday around 14:00 hours but can be reached on my home phone after 21:00. Please feel free to contact me at any time day or night.

In that letter, you provided diverter and BOP information for the Arctic Fox which recently drilled the Wolf Creek #4 well. The drilling program has not changed, however the diverter line on the Arctic Fox is smaller than that of Nabors 105. Specifically for the Gubik #4, the diverter line is 12" while 12 -1/4" hole will be drilled. This combination has been approved previously and is acceptable in this case per 20 AAC 25.035 (h)(2). A copy of this message should be available at the rig site. Call or message with any questions. Tom Maunder, PE AOGCC 3/9/2009 • .

At that time, we had planned to drill this well using Nabors 105. Since then, our second rig, the Arctic Fox has become available and we intend to use it to drill Gubik #4. The change in rigs will facilitate the completion of our 3 -well exploration program before the end of tundra travel season. The change in drilling rigs includes several equipment changes that do not impact the drilling program but do impact the permit as issued. First, we plan to drill the 12 -1/4" surface hole using the rig's 21 -1/4" diverter along with its 12" diverter line. The previous rig had a 16" diverter line. Therefore, we respectfully request an exception to 20 AAC 25.035 (c) (1) (B) to allowing us to drill the surface hole using the 12" diverter line that comes with the Arctic Fox. Please note that exceptions were previously granted for this rig and this diverter line. Secondly, the Arctic Fox has an 11" 5000 psi BOP whereas the previous rig had an 11" 10000 psi BOP. This will not impact the drilling of the well because our previously permitted test pressures are: a) the BOPE to 3000 psi and b) the annular preventer to 2500 psi.

Included with our 10- 401 are all required exhibits and a plan of operations. The rig contracted for this well is Nabors 105. We plan to mobilize to Gubik 4 after drilling Chandler #1. We plan to drill the 12 -1/4" surface hole to 1050' using the rig's 21 -1/4" diverter along with its 16" diverter line. 9 -5/8" surface casing will be set and cemented at 1050'. We will then drill an 8 -3/4" hole using the rig's 11", 10000 psi BOPE. Based upon actual pressure data from Gubik #3 (3.9 miles away) and seismic pressure predictions, the - maximum expected BHP in Gubik #4 will be 2169 psi at 3470'. The maximum expected surface pressure will be 1787 psi. As such, we respectfully request an exception to 20 AAC 25.035 (e) (10) (A) allowing for testing the BOPE to 3000 psi. The 5000 psi annular preventer will still be tested to 50% of its rated pressure: 2500 psi. 7" intermediate casing will be set and cemented at 3470'. Finally, we plan to drill a 6 -1/8" hole to TD at 4240'. Based on pressure data collected - from Gubik #3, we believe that the pressure gradient in this hole section is normal. It is our plan to drill using the same 11" 10000 psi BOPE as the previous hole section but we will reduce the mud weight as appropriate to minimize formation damage. After drilling and logging at TD, the well will be plugged or completed and suspended in accordance with AOGCC regulations. We respectfully request approval of our10 -401. The necessary forms and documents are attached. If you have any questions or comments, please direct them to Skip Coyner at 907 - 273 -6305 (ofc), 907 - 440 -6647 (cell). Sincerely, . W. C.

We also are using the knowledge gained from drilling Gubik 3 - as it pertains to formation pressures, frac gradients and drilling hazards. Surface Hole: We expect to see a normal pressure gradient in the surface hole down to the surface casing setting depth of 1050'. After cementing 9 -5/8" surface casing, we should achieve a LOT of +/- 20 ppg: although a LOT of 14 ppg is adequate to drill the next hole section. The measured formation pressures from Gubik 3 were +/- 8.0 ppg down to 1167'. Intermediate Hole: In the intermediate hole section (1050' to 3470') we expect to see a bove normal pressures as was the case in Gubik 3. The seismic derived pore pressure plot coincides with the actual data acquired from Gubik 3 both of which indicate a formation pressure gradient between 9.6 ppg and 12.1 ppg. The measured formation pressure gradients from this hole section in Gubik 3 include: • 12.1 ppg gradient 1530' possibly supercharged • 12.0 ppg gradient 3154' possibly supercharged • 11.4 ppg gradient 3216' possibly supercharged • 11.2 ppg gradient 3276' possibly supercharged The actual formation pressure data was used by Mr. James Lang to calibrate his seismic pressure predictions (see attached). Applying what we learned from Gubik 3 and using Mr. Lang's pressure predictions, our well plan includes adjusting the mud r weight between 12.5 ppg and 13.5 ppg as needed to control formation pressures in this hole section. As always, the mud weight will be maintained as dictated by hole conditions. We plan to set 7" intermediate casing through the abnormally pressured formations thus allowing normal mud weight in the production hole section below. Hydrates: While drilling this hole section in Gubik 3, significant gas cut mud was seen even though the initial mud weight was 13.5 ppg. Increases in the mud weight did not suppress the gas and therefore it is believed that the gas was derived from drilling hydrates. If gas cut mud is seen in Gubik 4, we will initially assume it is "hydrate gas" and it will be dealt with ✓ by conventional drilling techniques including: cold mud, minimal circulating time, etc. Production Hole: After setting 7" intermediate casing, the well plan is to drill the 6 -1/8" hole through the Grandstand formation with minimal safe mud weight based upon the actual pressure data from Gubik 3. This is critical for two reasons: 1. We believe that minimal safe mud weight will minimize invasion and formation damage 2. We believe that minimal safe mud weight and setting 7" casing will prevent sticking the drill pipe • 1 As in the previous hole sections, our well plan is based upon actual pressure data ' acquired from Gubik 3. The measured formation pressure gradients in this hole section (Grandstand formation) in Gubik 3 include: • 7.95 ppg gradient 3546' • 7.94 ppg gradient 3554' • 7.93 ppg gradient 3560' As such, we expect to drill, log and possibly set a liner using 8.6 ppg to 9.2 ppg mud. H No H2S was seen while drilling Gubik 3 last winter. Furthermore, there have been no reports of H2S in the area inclusive of the wells drilled by the Navy many years ago. Therefore we do not expect to see any H2S, however, normal precautions will be taken including H2S monitors, etc. (see attachments and analysis by James Lang & S.

Name Signature Date Originator: Jim Dwyer Reviewed by: Hal Martens Customer Approval: Version: 1.2 September 23, 2008 Location North Slope Alaska Confidential 1 Date: September 23, 2008 1 • Anadarko Gubik #4 Well Summary Gubik #4 is to be drilled vertically to a planned depth of 4,240' MD. As with any exploration well there is pore pressure uncertainty. Logging will be done therefore consideration will need to be made concerning the use of mud products. Expected formation pressure in the production interval should be normal and a SF (solids free) FloPro will be used. All product needed for this well will be delivered to location by air or by rolligon. In order to minimize the need of having large quantities of product on hand and also reduce the amount of cuttings that need to be hauled away, it is suggested that a FLOPRO system be used to drill at least the production interval. Typical dilution rates have been much lower for the FLOPRO system than for any other water based system (Gel /water, KCI /polymer, PHPA) that has been previously used for exploration drilling in remote locations. Fluid Type Typical Dilution Rate (bbls of fluid per bbl of hole drilled) Gel /Polymer 5.8 — 8.1 bbls /bbl KCI /Polymer 6.1 — 6.5 bbls /bbl PHPA 5.5 — 6.5 bbls /bbl SF FloPro 3.5 — 3.6 bbls /bbl The resulting improvement in the dilution rate of the SF FLOPRO system over other systems has been shown to dramatically reduce haul -off costs of both cuttings and excess fluids. Have contingency products on hand in the event that a weight increase is needed and to also combat any lost circulation problems that may occur. Fluid and Drilling Concerns ➢ HSE. ➢ Differential sticking due to filter cake build up through the exposed sand intervals. ➢ Mud weight for hole /shale stability. ➢ Waste management. ➢ Wellbore stability throughout the drilling phase of the operations. ➢ Hole cleaning. ➢ Minimize formation damage in reservoir. ➢ Log and core quality. • Minimization and control of waste management cost for the "drill cuttings" and associated fluids. Monitoring and efficient utilization of the trucks and gravel washer as required for this operation.

The following lessons learned on that project should be applied to the planning for the Anadarko wells: • Insulated tanks should be used and heating will still be necessary. • Tank farm personnel should be available for loading and unloading of tanks and maintenance of all manifolds, valves, and fittings. • Fluid should be mobilized to disposal site as soon as possible as tanks are filled. The Rolligon tanks can hold 70 to 80 barrels but high mud weight must also be considered for volume transported (i.e, 13.6 ppg x 42 gal x 80 = 45,696 Ibs). • 2- centrifugal pumps to help Toad or offload fluid as needed also the ability to roll the fluid as needed to prevent settling or freeze up. • 3" manifold rigged up so that all tanks suction and riser lines are hooked into a central location • Job shack and gen set needed for tank farm personnel on location Location North Slope Alaska Confidential 4 Date: September 23, 2008 • Anadarko Gubik #4 FLUID WASTE MANAGEMENT A reserve pit will be built for cuttings storage while drilling. The cuttings will be frozen and then loaded into large cuttings boxes that will be hauled to Kuparuk or Deadhorse for disposal. Liquid waste will be stored in the tank farm which should consist of four 400 Bbl upright tanks. If transporation issues due to adverse weather are a big issue; then a minimum tank storage capacity should be enough for displacing well and circulating pit volume when final casing is set. A boiler will be rigged up for every 3 tanks to keep the liquid from freezing. The tanks, when they are delivered to location, should be fitted with any necessary ball valves or cam lock fittings. The parts need to be ordered to mate up the tanks and the rig or Vac Truck. Even with glycol heat on the tanks, the valves can freeze very easily and the butterfly valves built on the tanks sometimes may be difficult to open. The overall tank farm set needs a designated crew to run or rig up the farm so any freezing or valve issues can possibly be avoided. They would need to install and inspect all the proper equipment and fittings (boiler, trunk heaters, valves, fittings and hoses).

Based upon work done on previous wells in this area a M -I Gel spud mud is recommended for the surface interval. Gas hydrates may be encountered and precautions should be taken for such an occurrence (see "Surface Interval Hydrate Issue" enclosure). 9.625" surface casing will be set as per cementing procedures in drilling program.

Carbonaceous material and coal may be noted. Initial rheological properties of 35 -50 lb /100ft Yield Point and > 150 sec /qt Funnel Viscosities should be maintained through the permafrost. 9.625" surface casing will be set and the cement will be pumped in a single stage to surface. ➢ Gravel sizes that are larger than normal can cause hole - cleaning problems. If encountered be prepared to increase the viscosity. ➢ Excessive quantities of gravel and sand may indicate wellbore instability. Past exploration wells have increased properties up to a YP of -85 Ibs /100ft to combat this problem. ➢ When drilling excessive amounts of sand, large Gel sweeps are recommended to help seal the sands and to help minimize seepage losses in the sands. Do not use Caustic when building these Gel sweeps. The objective is to be able to get as much Gel as possible in fresh water to be used as the sweep. ➢ 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 1 %) and Nut Plug m (as allowed by MWD tools) to minimize clay to metal sticking. Drillzone (at 1 %) may also be needed to help with shaker screen blinding. ➢ Use as cold of water as possible for the initial make -up and for additions made to the mud system during the surface drilling operations. ➢ Maintain low flow rates for the initial 200' of drilling to reduce the chance of washing out the conductor shoe. ➢ Lost circulation could be a problem before interval TD. ➢ Swabbing in the clays may also be a problem. Maintain or slightly increase the mud weight (.1 ppg) and continue additions of Drilzone at 15 to 30 gallons per hour and wiper runs through the surface interval may be necessary to clear the wellbore of the problematic clays. Drilzone maintained at 1.0% is also recommended to help with clay related issues. ➢ To help insure good cement to surface after running the casing, condition the mud to a YP of at least 25 - 30 prior to cementing the casing or as recommended by Cemcade. Do not lower the YP beyond 25 to avoid trouble with sands that may be found on this well. Have Desco CF, Tannathin, SAPP, and water on hand to ensure the desired rheologies can be achieved. Use water sparingly to reduce the over all haul -off costs for this well. ➢ 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. Location North Slope Alaska Confidential 7 Date: September 23, 2008 • • Anadarko Gubik #4 Surface Interval Operations Recommendations: . ➢ M -I Gel Spud mud will be mixed on the rig. Add Soda Ash at 0.5 ppb and 25 ppb M -I Gel to the make -up water and allow the gel to hydrate as long as possible prior to mixing the other products. Use as cold of 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. ➢ Fluid weight is planned to be maintained at 10.0 ppg through out this interval. ➢ If seepage losses in sands occur, use MIX II to aid in sealing these sands. ➢ Run all solids control equipment. Add drill water below the shaker to avoid washing unwanted solids back into the active system. Waste minimization is "Extremely Important" on this well. All cuttings and liquids have to be stored on location and hauled as needed by Rolligon for disposal. There is a possibility however that we may be able to inject liquids down the annulus after the 7" casing has been set and tested. (See Waste Management Plan) ➢ Lower API fluid loss with Drispac Plus Superlo as needed to maintain hole stability. ➢ To control rheology additions of Desco CF may be needed. ➢ Lost circulation has been encountered on previous wells in this area. LCM pills successfully treated these losses. The recommended LCM pill formula for this interval is as follows: 1. 30 bbls of the existing fluid 2. 10 ppb Nut Plug Medium 3. 10 ppb MIX II Medium / Fine 4. 10 ppb Calcium Carbonate ➢ 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. ➢ Upon drill -out of the surface casing shoe, treat any cement returns with SAPP, Bicarb, and Citirc Acid as needed. Surface Interval Hydrate Issues Use the following guidelines to help minimize the effect that any hydrates which may have to the drilling operation. • ScreenKleen added to surface mud system has proved effective in North Slope operations. • 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.

Maintain mud weights as per program guidelines and or hole conditions and ensure that rheology is optimized to reduce ECD's to a manageable level while drilling. Pore pressure and shale stability uncertainties do exist and care should be taken while drilling this interval. Monitor for any fluid losses and flow back closely. ➢ Mud weight -up to 12 ppg will be needed prior to drilling through the Tuluvak. If practical, any additional fluid weight adjustments should be performed in 0.1 — 0.2 ppg increments using MI WATE or a weighted "spike" fluid. Keep current with directional drillers and mud loggers on MD depths and geological information. ➢ If additional mud weight increases are required, control the ROP and flow rates as needed to avoid inducing a breakdown of any formations while drilling in the lower portion of this interval. Reduce pump rates immediately if packing off occurs. Pump high viscosity sweeps and ream carefully to clean the hole before proceeding with further drilling ➢ Additions of Resinex and Asphasol Supreme may be used to help lower the HPHT FL ( <10cc @ 200 deg F) and ensure shale stability in the lower portion of the well. Additions of these products may not be desirable if coring or MDT work will performed. ➢ 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. ➢ Although not expected lost circulation may be a problem for this interval due to the possibility of depleted areas. Avoid drilling practices that could contribute to the breakdown and subsequent losses. Tripping and casing running speeds should be monitored closely. Rheology and mud weight should also be held within tight specification. ➢ 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 high viscosity /weighted sweep and observe bottoms up again. ➢ Fluid deliveries, fluid transfers, and cuttings disposal issues will be tracked on a daily basis.

Care should be taken to monitor all drilling criteria to ensure that "best" drilling practices are being observed. • Interval pore pressures may vary. Mud weight requirements of 13.5 ppg at 1,410' MD (Top of Tuluvak) may be necessary. Uncertainty does exist; shale stability and pore pressures could require a higher or lower mud weight. Any fluid weight adjustments should be performed in 0.1 — 0.2 ppg increments using MI WATE or a weighted "spike" fluid. Keep current with directional drillers and MWD personnel on MD vs. TVD depths for the following weight up points • K+ concentration will be maintained at 28,000 — 32,000 throughout the interval. • KlaGard concentration will be maintained at 8 lb/bbl throughout the interval. • The potential for lost circulation and /or differential sticking is present if the fluid weight is increased in the later portion of this interval. To help avoid issues such as these use the following as a guideline: 1. Manage ECD's • Maintain low gravity drilled solids to below 6% with solids control equipment and dilution. • 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. • Run TripPro Module of Virtual Hydraulics for surge /swab predictions with actual well bore and fluids data prior to RIH /POOH. Distribute and adhere to trip schedule. 2. Prior to TOOH • Circulate until a clean hole ECD is attained (< 0.5 ppg above predicted ECD). • If deemed necessary, spot a pill containing —5 ppb SafeCarb 250, 5 ppb SafeCarb 500 and 15 ppb G -Seal to cover any under pressured zones that may be found. • Keep the pipe moving as much as possible. 3.

On the Permit to Drill form for the proposed Gubik 4 well, the property designation is listed as ASRC Lease CA007, but the lease designation presented on the Gubik 4 Drill Site plat (the plat with the USGS topo map in the background) is ASRC Lease CS007. I believe that CA007 is the correct designation, but need confirmation from you. 2. While checking Commission's records, I noticed that Anadarko hasn't filed a Notice of Ownership form for this ASRC Lease. Regulation 20 AAC 25.022 states: "Within 15 days after a person becomes an owner of a property on which operations subject to this chapter are proposed to the commission or are being conducted, the person shall file a Notice of Ownership (Form 10- 417)." The definition of an "owner" is provided below. Form 10-417 is fairly simple, and it is available on the Commission's web site at http: l/ www. aogcc. alaska .govlformsiformsindex.shtml. Teresa Imm of ASRC or someone with a similar level of authority will have to sign the form for ASRC as the "Transferor." Powers of Attorney or similar evidence of signatory authority must be provided for everyone who signs the form. We went through this process last year with Gubik 3. As I recall ASRC had some objection to providing the form 10 -417, but I don't remember the specifics. Form 10-417 is the simplest means to notify the Commission of ownership changes; otherwise, the Commission will need a copy of the signed Memorandum of Oil and Gas Lease for the Gubik 4 lease, which must include a legal description of the property covered by the lease. A Power of Attorney or similar proof of signatory authority must be provided for every corporate officer that signed the memorandum. Once I receive the memorandum and proofs of signatory authority, I will then check with the Commissioners to ensure that such a memorandum is acceptable to them. 3. If Anadarko is not 100% owner of the lease, Designation of Operator forms (Form 10 -411) must be provided by each of the other owners, along with a Power of Attorney or similar proof of signatory authority for everyone signing the forms. This form is also available on the Commission's web site through the hyperlink provided above. Thanks for your help, 1/2/2009 Page 2 of 2 Steve Davies Sr. Petroleum Geologist Alaska Oil and Gas Conservation Commission (907) 793 -1224 Pertinent definitions from Commission Regulations and State Statutes are: "owner" means the person who has the right to drill into and produce from a pool and to appropriate the oil and gas the person produces from a pool for that person and others.
