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. If you require any additional information, please contact me or my alternate, Jerry Murphy, at 659 -5102. Sincerely, Torin Roschinger BPXA, Well Integrity Coordinator • • BP Exploration (Alaska) Inc.

The permit to redrill 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. 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.

Specific prep work, (Phase 1) and drilling, (Phase 2) operations are detailed below. /"' Phase 1: Isolate & integrity test inner annulus, (IA). Set whipstock. Mill window if service coil i available. ~"~. Planned for April 29, 2001 _,-~~ · Drift well with dummy whipstock. ~"~ ] · Integrity test IA after displacing to seawater & installing dummy gas lift valves. L~ (/' · Set through tubing whipstock using e-line at approx. 12,030' '~ · Pump cement past the whipstock to P&A the existing perforations. · Mill window with service coil if available. Phase 2: Drill and Complete CTD sidetrack: Planned for May 10, 2001 2-3/8" coil will be used to drill a -2200 foot, 3-3A'' open hole sidetrack, (as per attached plan) and run a solid, cemented & perforated 2-7/8" liner completion. Mud Program: · Phase 1: Seawater · Phase 2: Seawater and FIo-Pro (8.6 - 8.7 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: · 2 7/8", 6.16#, L-80, solid liner be run from 11,125' (TOL) to TD. Liner will be cemented in place with approximately 22bbls (annular volume plus 25% excess in OH) of 15.8ppg class G cement. Well Control: · BOP diagram is attached. · Pipe rams, blind rams and the CT pack off will be pressure tested to 300 psi and to 3500 psi. · The annular preventer will be tested to 400 psi and 2200 psi. Directional · See attached directional plan · Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. Logging · An MWD Gamma Ray log will be run over the open hole section. · A MCNL will be run in the cased hole. Hazards H2S was measured at 8 ppm on May 16, 1998. The well-path will cross 4~_~mapped faults. Offset wells indicate there is a high risk of lost circulation along the wellpath. Reservoir Pressure Res. press, is estimated to be 3300 psi at 8800ss. Max. surface pressure with gas (0.12 psi/ft) to surface is 2244 psi.
