Sundry approval 308-046 was granted on February 15, 2008 authorizing BP to plug back - or si etrack drilling. Your requested change is approved as outlined below. Since work has not commenced under this sundry approval, there is no need to send a new 10-403 -this email and your request should be sufficient to amend sundry approva1308-049. 1) Set cement retainer @ 10,936 ft (50 ft above 2-7/8" tubing cut @ 10,986 ft MD) -approved; this is a variance to the requirements of 20 AAC 25.112(c)(1)(D) which requires the retainer to be within 500 feet of the perforated interval; new setting depth for the cement retainer will be 774 ft above perforated interval since cannot be set in 2- 7/8" tubing. 2) Cement volume -pump 13 barrels of cement for this abandonment (your request was for 9 bbls). Cement calculations are as follows: 4.5" from retainer to top of 2-7/8" (50 ft) - 0.8 bbls 2-7/8" x 4-1/2" annulus to Baker Anchor packer @ 11420 ft MD (434 ft) - 3.5 bbls 2-7/8" to CIBP @ 12185 ft MD (1199 ft) - 6.9 bbl Perfs squeeze -1.5 bbl (your number) Contact me if you have any questions.

The purpose of this request to comply with the intent of 20 AAC 25.112 (D). As discussed, we can not set a retainer inside the coil tubing- 50' above the perforations. However, I am proposing to set the cementing retainer 50' above the 2-7/8" tubing cut at 10,936' MD. The new cementing program for E-10 will be as follows: Plug and abandon the open perforations with 9 bbls of 15.8 ppg cement with retainer set at 10,936' MD - 50' above the 2-7/8" tubing sleeve at 10,986' MD. Squeeze 9 bbls of cement to plug and abandon the perforations. 3/11/2008 E-1 OA P&A Page 2 of 2 Cement volume calculations is based on placing cement on top the CIBP at 12,185' MD. This allows for pumping 1.5 bbls squeezed into the perfs.

This well is currently shut-in due to inability to determine the source of a small inner annulus leak. The new well is targeted to develop reserves in Ivishak Zone 1 B. The plan is to exit the parent E-10A well bore at 9,830' MD. A whipstock will be run and an 8-1/2" window will be milled in the 9-5/8" casing. An 8-1/2" hole will be drilled to the Top of the Sag River formation. A 7" drilling liner will be run, and will be fully cemented to the liner top. The 6-1/8" well bore then builds to horizontal targeting Zone 1 B. The planned well bore runs horizontally for approximately 1,235'. A 4-112° solid production liner will be run and will be perforated with 150' liner lap into the 7" drilling liner. A 7" tieback will be run and partially cemented.

The permit to rcdrill docs 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. 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. Robert N. Christcnson, P. E.

The sidetrack, E-10a, will target Zone 1 reserves immediately above the HOT. This sidetrack will be conducted in two phases. Phase 1: Downsqueeze abandonment cement, set whipstock anchor: Planned for 7114199. · Squeeze holes will be punched in the 4 %" straddle at approx. 11,565'. A bridge plug will be set at approx. 11,500'. Tubing will be pressure tested prior to shooting squeeze holes at 11,300'. · Existing perorations will be abandoned with approx. 30 bbls cement. Abandonment cement will be downsqueezed through squeeze holes at 11,300' thereby stabilizing the 4 %" straddle and cementing off existing perorations. Abandonment cement will be pressure tested to 1500 psi with AOGCC witness. · A mechanical whipstock anchor will then be set on e-line at approx. 11,447'. Phase 2: Install Whipstock Tray, Mill Window and Drill Directional Hole: Planned for 7119199. Directional drilling coil tubing equipment will be rigged up and utilized to install the whipstock tray, mill the window through two strings (4 ½"x 7") and drill the directional hole as per attached plan. Mud Program: - Phase 1: Seawater - Phase 2: FIo-Pro (8.8 - 8.9 ppg) Disposal: - No annular injection on this well. - All drilling and completion fluids and other Class II wastes will go to CC-2a for injection. - All Class 1 wastes will go to Pad 3 for disposal. Casing Program: - 2 7/8", 6.16#, L-80, ST-L liner will be run from TD to approx. 11,000' MD and cemented with approx. 20 bbls. to bring cement 200 ft above the window. 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: 11,447' MD (8,823' TVD ss) - TD: 12,687' MD (8,965' 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.
