ITEM 1a: Classification of Service Wells: Gas Injection, Water Injection, Water-Alternating-Gas Injection, Salt Water Disposal, Water Supply for Injection, Observation, or Other. Multiple completion is defined as a well producing from more than one pool with production from each pool completely segregated. Each segregated pool is a completion. ITEM 4b: TPI (Top of Producing Interval). ITEM S: The Kelly Bushing and Ground Level elevation in feet above mean sea level. Use same as reference for depth measurements given in other spaces on this form and in any attachments. ITEM 13: The API number reported to AOGCC must be 14 digits (ex: 50-029-20123-00-00). ITEM 20: Report true vertical thickness of permafrost in Box 20. Provide MD and TVD for the top and base of permafrost in Box 28. ITEM 22: Attached supplemental records for this well should show the details of any multiple stage cementing and the location of the cementing tool. ITEM 23: If this well is completed for separate production from more than one interval (multiple completion), so state in item 1, and in item 23 show the producing intervals for only the interval reported in item 26. (Submit a separate form for each additional interval to be separately produced, showing the data pertinent to such interval). ITEM 26: Method of Operation: Flowing, Gas Lift, Rod Pump, Hydraulic Pump, Submersible, Water Injection, Gas Injection, Shut-In, or Other (explain). ITEM 27: Provide a listing of intervals cored and the corresponding formations, and a brief description in this box. Submit detailed description and analytical laboratory information required by 20 AAC 25.071.

The well is currently secured by two EZSV bridge plugs; one at 3000' MD and the other at 9830' MD, which were placed in the well during the (failed) workover attempt. The plan for the workover had been to replace the tubing due to tubing by IA communication. Unfortunately "junk" was left on top of the 2-7/8" liner at 10028'. Plans were developed in mid-2006 to sidetrack the well, but that sidetrack has not yet occurred. Therefore, since the well is adequately secured, BP would like to change the status of the well to Suspended in order to retain the ability to sidetrack this well in the future. Thank you very much for your assistance in this matter.

This Zone 2 Ivishak producer is currently shut-in fortû6T¡'~IA communication and a failed workover in May/June of 2005 and is currently secured by 2 EZSV bridge.e!YgS at 3000' MD and 9830' MD which were placed in the well during last year's failed work- 0~1I (D-26), which was originally completed in 02/86, was sidetracked with coil in 1997 and completed as a Zone 2 producer. In 08/04, T x IA communication was noted and a rig work-over was planned to replace the 4-1/%completion string, however, problems during the work-over place the well into its current inoperable status. With "junk" on top of the current 2-7/8" liner at 10,157' MD (milled decompletionlpacker debris, a lost IBP, etc.) and low probability that we can squeeze cement to the current perforations at 10,730'- 10,750' MD, the current plan to P&A this well is to place -250' of 15.8 ppg Class G cement on top of the lower /' EZSV currently in the well at 9830'. As the 9-5/8" casing in this well has been successfully tested to 3500 psi from 9850' MD (5/10105), the current sidetrack plan is to make a whip-stock exit of the parent D-26B wellbore in the existing 9-5/8" casing at -8320' MD with an 8-1/2" drilling assembly. The 8-1/2" hole will be drilled to the top of the Sag River formation where 1''';/ a 7" liner will then be run and cemented. A 6-1/8" wellbore will then be built to horizontal, landing just above the base of Zone 2B. The planned 6-1/8" hole will then be drilled horizontally for approximately 663' staying above the HOT. A solid 4-1/2" production liner will be cemented in place when the well is TD at a planned depth of 12,626' MD. The D-26B sidetrack is currently scheduled for DOy¢14,,4, eþéginning the first week of October, 2006. The pre· rig work for this sidetrack will be priority scheduled ~Ge"Sundry approval has been obtained.

Supervisor DATE: April 20, 2001 FROM: Chuck Scheve; SUBJECT: Petroleum Inspector Safety Valve Tests Prudhoe Bay Unit D Pad Friday, ADri! 20, 2001: I traveled to BPXs D Pad and witnessed the semi annual safety valve system testing. As the attached AOGCC Safety Valve System Test Report indicates ! witnessed the testing of 20 wells and 40 components with 1 failure. The surface safety valve on well D-06 had a slow leak when pressure tested. This valve was serviced and the retest witnessed on this date. Merv Liddlow performed the testing today; he demonstrated good test procedures and was a pleasure to work with. A walk through inspection of the well houses on this pad was performed during the SVS testing with no problems noted. All well houses inspected were reasonably clean and all equipment appeared to be in fair conditions. Su. mmary; I witnessed the semi annual SVS testing at BPXs D-Pad.

As the attached AOGCC Test Report shows the test lasted 3 hours and there were no failures. The testing went very well with good test procedures being employed by the Nordic crew. The Rig was clean and ali related equipment appeared to be in good condition. SUMMARY: I witnessed the initial BOPE test on Nordic Rig 1 drilling BPXs D-26 A Well.

Phase 2: Drill Directional Hole: Planned for 6/4/97. - Directional drilling coil tubing equipment will be rigged up and utilized to mill the window and drill the directional hole per attached plan to a TD of 12,435' MD (8,960' -I-VDss). Mud Program: - Phase 1: Seawater - Phase 2: FIo-Pro (8.8 - 8.9 ppg) Casing Program: - 2 7/8", 6.16#, L-80, ST-L liner will be run from TD to approx. 10,165' MD and cemented with approx. 17 bbls. cement. The well will then be perforated with coil 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: 10,816' MD (8910' TVD ss) - TD: 12,435' MD (8860' TVD ss) - Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. Logging - A Gamma Ray log will be run over all of the open hole section. /CNL/Densitylogs are tentatively scheduled.
