BOX 100360 ANCHORAGE, ALASKA 99510-0360 April 23, 2003 Mr. Tom Maunder Alaska Oil & Gas Commission 333 West 7th Avenue, Suite 100 Anchorage, AK 99501 Dear Mr. Maunder: Enclosed please find a spreadsheet with a list of wells from the Alpine field (CRU). Each of these wells was found to have a void in the conductor by surface casing annulus. The voids were filled with cement to the top of the conductor. As per previous agreement with the AOGCC, this letter and spreadsheet serves as notification that the treatments took place. In the fall of 2002, CD 1-23 was reported to have a "wobbly" tree. The top of cement was measured at 15- feet below the top of the conductor. Plans were made to stabilize the wellhead by top-filling cement later in the winter when the ice road to Alpine had been installed. Since that is considerable effort and expense for pumping a small load of cement, a survey was made of each conductor to see if voids were present. A list of 34 wells was put together that would need additional cement. The top-fill operation was started on April 15th and was completed on April 16th, 2003. Dowell- Schlumberger batch-mixed Arctic Set I cement to 15.7 ppg in a blender. The cement was pumped via high-pressure hose into the conductor. The cement was brought to the top of conductor on each well. The blender/pump and hose worked down the line, filling the identified wells until the list was completed. The attached spreadsheet presents the well name, top of cement depth prior to filling, and the number of sacks used on each conductor. Please call MJ Loveland or Nina Woods at 907-659-7224, or me at 659-7043 if you have any questions.

Although LWD logs and samples will be obtained, the AOGCC understands there are no plans to test CD 2-33A. Furthermore, the application for permit to drill (201-124) includes the details of the plug and abandonment operations of the reserVoir delination portion of well CD2-33A. As long as the proposed P & A plans for CD2-33A are followed, it is not necessary to submit a separate 10-403 for AOGCC approval, however, any changes to the proposed plans may require the submission of a 10-403. Sufficient notice (24 hours) must be given to allow a representative of the Commission to witness the P & A operations. The permit to drill does not exempt you from obtaining additional permits required by law from other governmental agencies, and does not authorize conducting drilling operations until all other required permitting determinations are made. 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. Annular disposal has not been reqUested as part of the Permit to Drill application for CD2-33A. Please note that any disposal of fluids generated from this drilling operation which are pumped down the surface/production casing annulus of a well approved for annular disposal on cD-2 pad have to comply with the requirements and limitations of 20 AAC 25.080. ApProval of this permit to drill does not authorize disposal of drilling waste in a volume greater than 35,000 barrels through the annular space of a single well or to use that well for disposal purposes for a period longer than one year. Blowout prevention equipment (BOPE) must be tested in accordance with 20 AAC 25 035. Sufficient notice (approximately 24 hours) must be given to allow a representative of the Commission to witness a test of BOPE installed prior to drilling new hole. Notice may be given by contacting the Commission petroleum field inspector on the North Slope pager at 659-3607. Permit No: 201-124 Page 2 of 2 All dry ditch sample sets submitted to the Commission must be in no greater than 30' sample intervals from below the permafrost or from where samples are first caught and 10' sample intervals through target zones. Blowout prevention equipment (BOPE) must be tested in accordance with 20 AAC 25.035. Sufficient notice (approximately 24 hours) of the BOPE test performed before drilling below the surface casing shoe must be given so that a representative of the Commission may witness the test. Notice may be given by contacting the Commission petroleum field inspector on the North Slope pager at 659-3607. Sincerely, Julie M.

Well Proximity Risks: Directional drilling / collision avoidance information as required by 20 ACC 25.050 (b) is provided in following attachments. CD2-33 will be the closest well to CD2-42PH. Accounting for survey tool inaccuracies, the ellipse separation between these wells will be 13.6' at 8800' MD. Drillinq Area Risks: There are no high-risk events (e.g. over-pressures zones) anticipated. Lost circulation: Faulting within the Alpine reservoir section is considered to be the most likely cause of lost circulation. Standard. LCM material has proved effective in dealing with lost circulation in previous development wells. Additional care and attention will be given to the higher potential of inducing a kick when drilling horizontally as opposed to vertically. Good drilling practices will be stressed to minimize the potential of taking swabbed kicks. Annular Pumpinq Operations: Incidental fluids developed from drilling operations on well CD2-33 will be disposed of into the annulus of another permitted well on the CD2 pad or the CD1-19a Class II disposal well. This well will not be permitted for annular disposal. CD2-33A DRILLING FLUID PROGRAM, .....

Keep flowline viscosity at _+ 200 sec/qt while drilling to the base of the permafrost. Lower viscosity to 90 sec/qt from the base of the permafrost to TD of the surface hole. Maintain mud weight < 9.6 ppg by use of solids control system and dilution where necessary. Intermediate Hole Sections CD2-33A: Fresh water gel / polymer mud system. Ensure good hole cleaning by maintaining fluid rheology and maximizing fluid annular velocity. There is potential for lost circulation, particularly after the Alpine is penetrated. Maintain mud weight at or below 9.8 ppg and be prepared to add loss circulation material. Good filter cake quality, hole cleaning and maintenance of Iow drill solids (by diluting as required) will all be important in maintaining wellbore stability. Production Hole Section: The horizontal production interval will be drilled with a M-I FIo-Pro drill-in fluid. The base fluid will consist of 6% KCl, with _ 30PPB calcium carbonate bridging material to minimize formation damage. FIo-Vis Polymer and DuaI-FIo starch will be used for viscosity and fluid loss control respectively.

PROCEDURE FOR CALCULATING ANTICPATED SURFACE PRESSURE (ASP) ASP is determined as the lesser of 1) surface pressure at breakdown of the formation casing seat with a gas gradient to the surface, or 2) formation pore pressure at the next casing point less a gas gradient to the surface as follows: 1) ASP = [(FG x 0.052) - 0.1]D Where: ASP = Anticipated Surface pressure in psi FG = Fracture gradient at the casing seat in lb./gal 0.052 = Conversion from lb./gal to psi/ft 0.1 = Gas gradient in psi/ft D = true Vertical depth of casing seat in ft RKB OR 2) ASP= FPP- (0.1x D) Where; FPP = Formation Pore Pressure at the next casing point , ASP CALCULATIONS Drilling below conductor casing (16") ASP = [(FG x 0.052)- 0.1} D = [(10.9 x 0.052)- 0.1] x 114 = 53 psi OR ASP = FPP - (0.1 x D) = 1688 - (0.1 x 3730') = 1315 psi 2. Drilling below surface casing (9 5/8") ASP = [(FG x 0.052)-0.1} D = [(14.5 x 0.052)- 0.1] x 3730'= 2440 psi OR ASP = FPP - (0.1 x D) = 3395- (0.1 x 7502') = 2645 psi Alpine, CD2-33A Cementinq Requirements CD2-33 A Cement Plug #1: 15339' MD to 14775' MD = 564'.

The intended spud date for this well is June 30, 2001. It is intended that Doyon Rig 19 be used to drill the well. This well will consist of two reservoir evaluation pilot bore targets that will be abandoned and one CD2 pad horizontal development well. All 3 targets will share a common surface location and surface hole. The CD2-33PB1 is designed to penetrate the Alpine West target location that was dropped from the winter exploration drilling schedule do to this years shortened exploration season. CD2-33PB1 will be plugged and abandoned prior to sidetracking to the CD2-33PB2 target. CD2-33PB2 will be sidetracked off of the CD2-33PB1 wellbore. The CD2-33PB2 target will be used to confirm the seismic interpretation of the Northwestern portion of the Alpine reservoir within the CD2 Pad development. CD2-33PB2 will be plugged and abandoned prior to sidetracking to the final CD2-33 target The CD2-33 horizontal producer will be sidetracked through a window milled in the 9- 5/8" surface casing. After milling out a window, the 8-1/2" intermediate hole will be drilled to the 7" casing point in the Alpine reservoir. After setting 7" intermediate casing, the horizontal section will be drilled and the well completed as an open hole producer. At the end of the work program, the well will be closed in awaiting the start-up of CD2 pad, which is tentatively scheduled for August 2001. . 5. 6. 7. 8. 9. 10.

Well Proximity Risks: Directional drilling / collision avoidance information as required by 20 ACC 25.050 (b) is provided in following attachments. CD2-33 will be the closest well to CD2-42PH. Accounting for survey tool inaccuracies, the ellipse separation between these wells will be 13.6' at 8800' MD. Drillinq Area Risks: There are no high-risk events (e.g. over-pressures zones) anticipated. Lost circulation: Faulting within the Alpine reservoir section is considered to be the most likely cause of lost circulation. Standard LCM material has proved effective in dealing with lost circulation in previous development wells. Additional care and attention will be given to the higher potential of inducing a kick when drilling horizontally as opposed to vertically. Good drilling practices will be stressed to minimize the potential of taking swabbed kicks. Annular Pumpinq Operations: Incidental fluids developed from drilling operations on well CD2-33 will be disposed of into the annulus of another permitted well on the CD2 pad or the CD1-19a Class II disposal well. This well will not be permitted for annular disposal.

Keep flowline viscosity at _+ 200 sec/qt while drilling to the base of the permafrost. Lower viscosity to 90 sec/qt from the base of the permafrost to TD of the surface hole. Maintain mud weight < 9.6 ppg by use of solids control system and dilution where necessary. Intermediate Hole Sections CD2-33PB1, PB2 & CD2-33: Fresh water gel / polymer mud system. Ensure good hole cleaning by maintaining fluid rheology and maximizing fluid annular velocity. There is potential for lost circulation, particularly after the Alpine is penetrated. Maintain mud weight at or below 9.8 ppg and be prepared to add loss circulation material. Good filter cake quality, hole cleaning and maintenance of Iow drill solids (by diluting as required) will all be important in maintaining wellbore stability. Production Hole Section: The horizontal production interval will be drilled with a M-I FIo-Pro drill-in fluid. The base fluid will consist of 6% KCl, with _+ 30PPB calcium carbonate bridging material to minimize formation damage. FIo-Vis Polymer and DuaI-FIo starch will be used for viscosity and fluid loss control respectively. { ....
