Severe lost circulation could not be stopped and deteriorating hole conditions resulted in a decision to abandon the open hole while preserving the window for a future sidetrack. On 12/11/99 a 30 bbl gel-diesel pill was pumped into open hole to stop losses. This treatment was then cleaned out to 11000' and 15.8 ppg cement was layed from 10985' to 10650'. The window is at 10873' - 10886'. This cement plug was tested to 1500 psi with AOGCC witness. Operations on B-26A have been shut down pending evaluation of future sidetrack possibilities. Lower wellbore is abandoned in preparation for sidetrack. _.~~fêÐt~r9p:~r~ti~n§~Þt.1tCl2""f")-J\Pproved 04/24/00, Approval #300-098 The plan forward was to clean out cement to the window and use the existing window for the B-26B sidetrack. The bottom hole location for B-26B has changed by greater than 500', hence the new well name and API number extension. (See 10-407 for B-26B for details.)

The following summarizes the procedure required to prepare B-26 for sidetracking and is submitted as an attachment to Fonn 10-403. A schematic diagram of this proposed completion is attached. Note that a coil sidetrack ofB-26 was attempted in December, 1999 under Pennit 199-102. Severe lost circulation was encountered, the sidetrack was plugged back to the window and an "operation shutdown" was submitted. The whipstock and window used for B-26a PB#l are currently covered with cement to a depth of 10,650'. The whipstock is at 10,870'. The plan is to clean out cement to the window and use this existing window for the B-26a sidetrack. The bottom hole location for B-26a has changed by 517 ft from the BHL pennitted for B-26a PB#l. Prior to re-entering B-26 for sidetracking the following work is planned: 1. Drift the tubing with a dummy drilling assembly. 2. Service and pressure test tree valves. Steps 1 and 2 are scheduled for April 21, 2000. a~ Ted Stagg çtÝ-Y-~ij 'f CT Drilling Engineer cc: Well File Petrotechnical Data Center RECE\VEO APR 1 3 2000 sK& au &. Gas Cons.

Severe lost circulation could not be stopped and deteriorating hole condition resulted in a decision to abandon the open hole while preserving the window for a future sidetrack. On 12/11/99 a 30 bbl gel-diesel pill was pumped into open hole to stop losses. This treatment was then cleaned out to 11,000 ' and 15.8 ppg cement was layed from 10,985' to 10,650'. The window is at 10,870-10,886'. This cement plug was tested to 1500 psi with AOGCC witness. Operations on B-26a have been shut down pending evaluation of future sidetrack possibilities.

The sidetrack, B-26a, will target Zone 4A and 4B reserves. This sidetrack will be conducted in two phases. Phase 1: Set Whipstock: Planned for Nov. 24, 1999. · A Tubing Integrity Test was successfully performed on 9/26/99. · The whipstock drift was run to 11,191' on 9/19/99. · A Kinley caliper run on 9/19/99 found tubulars in good condition. Phase 2: Cement perfs, mill window and drill sidetrack: Planned for Dec. 1, 1999. Directional drilling coiled tubing equipment will be rigged up and utilized to cement perforations,mill the window and drill the directional hole as per attached plan to planned TO of 12,629' MD (8,780' TVDss). Mud Program: · Phase 2: Seawater and Flo-Pro (8.7 - 8.8 ppg) Disposal: - No annular injection on this well. - All drilling and completion fluids and all other Class II wastes will go to Grind & Inject. - All Class I wastes will go to Pad 3 for disposal. Casing Program: - 27/8",6.16#, L-80, ST-L liner will be run from TD to approx. 10,485' MD and cemented with approx. 20 bbls. cement to bring cement 200 ft above the window. The well will then be perforated with coiled tubing conveyed guns. Well Control: - BOP diagram is attached. - Pipe rams, blind rams and the CT pack off will be pressure tested to 400 psi and to 4000 psi. - The annular preventer will be tested to 400 psi and 2000 psi. Directional - Kick Off: 10,875' MD (8,586' TVD ss) - TD: 12,629' MD (8,780' TVD ss) - Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run.

Drilling Permit 199-102 was issued for B-26a on 10/27/99. Since that time the well design has changed. The pilot hole, originally planned, has been deleted. The BHL has moved approx. 188 ft to the NÆ. Other well design criteria are essentially unchanged. A new directional plan, completion schematic and summary of operations are attached along with a new Form 10- 401.

The permit to redrill does not exempt you from obtaining additional permits rcquircd by law from other govenlmental agencies. and does not authorize conducting drilling operations until all other required permitting determinations are made. In accordance with 20 AAC 25.005(f). all records. data and logs acquired for the pilot hole must be clearly differentiated in both name (B-26APH) and API number (50-029-20976-70) from records, data and logs acquired for well B-26A. 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 \YÍtness 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. rft7&L~- Robert N. Christenson. P. E.

The sidetrack, B-26a, will target Zone 4A and 4B reserves. This sidetrack will be conducted in two phases. Phase 1: Set Whipstock: Planned for Oct. 25, 1999. · A Tubing Integrity Test was successfully performed on 9/26/99. · The whipstock drift was run to 11 191' on 9/19/99. · A Kinley caliper run on 9/19/99 found tubulars in good condition. Phase 2: Cement perfs, mill window and drill pilot hole and lateral: Planned for Nov. 1, 1999. Directional drilling coiled tubing equipment will be rigged up and utilized to cement perforations, mill the window and drill the pilot hole. After logging the pilot hole, the well will be partially plugged back with cement and sidetracked to the final BHL. directional hole as per attached plan to planned TO of 12,424' MO (8,826' TVDss). Mud Program: · Phase 2: Seawater and Flo-Pro (8.7 - 8.8 ppg) Disposal: - No annular injection on this well. - All drilling and completion fluids and all other Class II wastes will go to Grind & Inject. - All Class I wastes will go to Pad 3 for disposal.

The well will then be perforated with coiled tubing conveyed guns. Well Control: - BOP diagram is attached. - Pipe rams, blind rams and the CT pack off will be pressure tested to 400 psi and to 4000 psi. - The annular preventer will be tested to 400 psi and 2000 psi. - Directional - See attachments. - Kick Off: 10,875' M D (8,586' TVD ss) ~\" ~ \ \ \ '\ "fL\ - TD: 12,424' MD (8,826' TVD ss) - Magnetic and inclination surveys will be taken every 30 ft.
