The corrosion inhibitor is engineered to prevent water from entering the annular space and causing external corrosion that could result in a surface casing leak to atmosphere. The attached spreadsheet represents the well name, API and PTD numbers, top of cement depth prior to filling and volumes of corrosion inhibitor used in each conductor. As per previous agreement with the AOGCC, this letter and spreadsheet serve as notification that the treatments took place and meet the requirements of form 10-404, Report of Sundry Operations.

O 2002 rvices rilling To: Blair Wondzell Date.' Philippa Stevenson Notification of Change to R-40 Drilling Program From: Subject: BP Exploration /ARCO Alaska Inc. November l~th 1998 Nabors 2ES is currently drilling the 6" hole section of grassroots well R-40 (permit no 98-200). Over the weekend the well was steered up into the base of the Kingak for the second time. This happened inadvertently when crossing over a sub-seimic fault. Pdor to penetrating the Kingak sliding had become increasingly more difficult and losses were being experienced at a variable rate. Upon reaching the Kingak at 12745', it was no longer possible to slide to steer down. Therefore a trip was made to pick up a rock bit in the hope that it would prove more steerable. However, on the trip back in, it was impossible to get back to TD, with several hours being spent reaming to bottom, with the hole packing off and losing fluid. The Kingak section appeared to be deteriorating. It was then decided that it would be necessary to re-drill through the target polygon to recover the well. Therefore an open hole side-track was performed from 10919' and current depth is 11793'. The new wellbore is being maintained approximately 10' TVD below the old hole. Should you require any further information please do not hesitate to contact either myself or Dan Stone at this office. D~il~ing Engineer Date Reviewed by: ~--'~--. "~. ~ ,, ),, J ~% ......

Diverter, BOPE and mud fluid system schematics on file with AOGCC. Bottom hole pressure is expected to vary between 2000 to 3000 psi @ 8740' TVDSS. Maximum expected surface pressure is 2150psi (assuming gas column of 0.1 psi/ft). Hazards Recent wells have not experienced problems through the surface hole section. There is a possibility of encountering a gas charged area below the Permafrost, which is the result of a casing leak in well R34. Also directional control below the Permafrost has been a concern in the past. This well kicks off at 400' and builds at 2.5 degress/100 ft through the Permafrost. In the intermediate section the Cretaceous interval is expected to be moderately over-pressured, around 9.5-9.6 ppg, 4000 -5000' MD. The Kignak shale can cause hole problems, fight hole stuck pipe with a combination of reactive an unstable shales. This well holds a tangent angle of 21 degrees through the Kignak which has been done on previous wells without too much trouble. A silicate/KCL mud system will be used to provide shale inhibition. Mud weights of 10 ppg or greater are advisable for hole stabil- ity. Shallow gas was also encountered on well R-28 in the lower Seebee (HRZ). The main production target for this well is the Sag River. Only two minor faults will be crossed in the polygon and recent wells drilled in this area have not experienced severe losses. The pad data sheet in- dicates that only one well (R-36i) has experienced major lost circulation in this production interval, most other drilling wells experiencing only minor losses. Hence, although preparations should be made to pump LCM, lost circulation is not expected to be a major problem. However the Sag River pressures vary from 2000 psi (4.3 ppg EMW) at the start of the horizontal to 3000 psi (6.5 ppg EMW) at the end. Therefore avoiding differential sticking should be a consideration. The use of the Quikdriln drilling fluid which is solids free and does not form a filter cake should ameliorate the risk. Differential sticking has occurred frequently on older wells in the Ivishak at +/-9183' TVD. Once the sticking occurs it is very strong and has created difficulty in freeing up the drillstring. On R-35A, the sticking was successfully alleviated by pumping a 20bbl pill of Liquid Casing, OM Seal, and Barafibre and reducing pump rate to 5bpm (to reduce ECD). Note however that these wells were drilled using LSND mud; since this well will employ solids free Quikdriln, this should mitigate the risk of sticking. High torque has been reported on several older wells in the production hole, hence some open hole lu- brication may be required. The pad data sheet incorporates wells from R, F and J pad as the bottom hole location of these wells are all in the same area. Wells from all three pads have experienced problems with bridges, tight hole, differential sticking, and packing off while in the production interval. This has caused numerous incidents of stuck logs, casing, and drillstring. This is a high potential stuck pipe area - be alert while drilling this interval and employ frequent reaming if any sign of unstable hole is seen. Note however, that recent R-pad wells have not experienced any trouble from sticking and it is expected that this well will be drilled without a significant sticking problem. The Boundary Fault is located to the south of the polygon, and hence this edge of the polygon is a hard- line to avoid crossing the fault. No potential close approaches have been identified on the directional programme for this well. Disposal All cuttings should be hauled to the ball mill at CC-2A for disposal. Haul all drilling and completion fluids and other Class II wastes to CC-2A for injection. Haul all Class I wastes to Pad 3 for disposal. Pre-Rig Work: Operations Summary 1. Set 20" conductor.

November 16th 1998 As per your conversation with Jim Smith last Fdday 13~ I am writing to confirm that well R-40 (permit no 98- 200) has reached TD early. Last Friday, when drilling 6" hole at 12819' it became clear that the well had once again penetrated the Kingak. The new wellbore was approximate}y 20' TVD lower than old hole. ( the well was subject to an open hole side-track as outlined in a previous communication to you 11/! 1/98). The risks of further penetration out-weighed the benefits and a decision was taken to complete R-40 at 12819', original TD being planned at 15711'. Due to the shorter hydrocarbon beadng zone exposed the completion tubing will be 3-1/2" rather than 4-1/2". In a~l other aspects the completion remains the same. Should you require any further information please do not hesitate to contact either myself or Dan Stone at this office.

Diverter, BOPE and mud fluid system schematics on file with AOGCC. Bottom hole pressure is expected to vary between 2000 to 3000 psi @ 8'740' TVDSS. Maximum expected surface pressure is 2150psi (assuming gas column of O. 1 psi/fO. Hazards Recent wells have not experienced problems through the surface hole section. There is a possibility of encountering a gas charged area below the Permafrost, which is the result of a casing leak in well R34. Also directional control below the Permafrost has been a concern in the past. This well kicks off at 400: and builds at 2.5 degress/100 ft through the Permafrost. In the intermediate section the Cretaceous interval is expected to be moderately over-pressured, around 9.5-9.6 ppg, 4000 -5000' MD. The Kignak shale can cause hole problems, tight hole stuck pipe with a combination of reactive an unstable shales. This well holds a tangent angle of 21 degrees through the Kignak which has been done on previous wells without too much trouble. A silicate/KCL mud system will be used to provide shale inhibition. Mud weights of 10 ppg or greater are advisable for hole stabil- ity. Shallow gas was also encountered on well R-28 in the lower Seebee (HRZ). The main production target for this well is the Sag River. Only two minor faults will be crossed in the polygon and recent wells drilled in this area have not experienced severe losses. The pad data sheet in- dicates that only one well (R-36i) has experienced major lost circulation in this production interval, most other drilling wells experiencing only minor losses. Hence, although preparations should be made to pump LCM, lost circulation is not expected to be a major problem. However the Sag River pressures vary from 2000 psi (4.3 ppg EMW) at the start of the horizontal to 3000 psi (6.5 ppg EMW) at the end. Therefore avoiding differential sticking should be a consideration. The use of the Quikdriln drilling fluid which is solids free and does not form a filter cake should ameliorate the risk. Differential sticking has occurred frequently on older wells in the Ivishak at +/-9183' TVD. Once the sticking occurs it is very strong and has created difficulty in freeing up the drillstring. On R-35A, the sticking was successfully alleviated by pumping a 20bbl pill of Liquid Casing, OM Seal, and Barafibre and reducing pump rate to 5bpm (to reduce ECD). Note however that these wells were drilled using LSND mud; since this well will employ solids free Quikdriln, this should mitigate the risk of sticking. High torque has been reported on several older wells in the production hole, hence some open hole lu- brication may be required. The pad data sheet incorporates wells from R, F and J pad as the bottom hole location of these wells are all in the same area. Wells from all three pads have experienced problems with bridges, tight hole, differential sticking, and packing off while in the production interval. This has caused numerous incidents of stuck logs, casing, and drillstring. This is a high potential stuck pipe area - be alert while drilling this interval and employ frequent reaming if any sign of unstable hole is seen. Note however, that recent R-pad wells have not experienced any trouble from sticking and it is expected that this well will be drilled without a significant sticking problem. The Boundary Fault is located to the south of the polygon, and hence this edge of the polygon is a hard- line to avoid crossing the fault. No potential close approaches have been identified on the directional programme for this well. Disposal All cuttings should be hauled to the ball mill at CC-2A for disposal. Haul all drilling and completion fluids and other Class II wastes to CC-2A for injection. Haul all Class I wastes to Pad 3 for disposal. Pre-Rig Work: Operations Summary 1. Set 20" conductor.
