Subject: Sundry S-08A change Date: Tue, 13 Mar 2001 22:26:14 -0000 From: "Endacott, Mary S" <EndacoMS@BP.com> To: "'Tom_Maunder@admin.state.ak. us'" <Tom_Maunder@admin.state.ak. us> CC: "Hubble, Terrie L" <HubbleTL@BP.com>, "Kara, Danny T" <KaraDT@BP.com> Tom Superseding previous letter dated March 2, 2001, the existing perfs will be isolated using a CIBP set at 9005'. Because there is Iow risk of cross flow in the existing perfs (9562'-10180') and the well is relatively tight, along with the plan to cement the liner of the proposed sidetrack to above the window, placing cement above the CIBP adding further isolation in the wellbore, a CIBP should be sufficient to prep the S-08A for sidetrack. Attached is a revised sketch showing proposed CiBP and sidetrack. <<S-08a proposed ClBP.doc>> Mary S.

St, 'Reservoir Engineer Revised Liner Lap for S-08a 'Well 8-08 is scheduled for a through tubing sidetrack to be drilled With. coiled tubing, The Permit to, Drill, 98-228, was issued on Nov. 18, 1gOB, Since that tlme the s~detrack has been re-designed to accommodate a future sidetrack. The S-0Ba sidetrack window will. be at the top of Zone 4, as deep as oOSSi,ble for this Zone 4 sidetrack. There is future sidetrack potential r this welt if the 7" liner is accessible below the top of the Sag River, To provide for this future sidetrack option, BP is requesting' that the 2 7/8" liner for S-08a be terminated 50 ft above the window.' This requires a variance from AAC 2{5.030 (7)(d)(§)(B) that requires a,. "minimum o1' 100 feet of cemented lap~. A 50 ft lap will place tt~e top or the cemented 2 7/8" liner within the Shublik interval, some 78 ft b'elow the top of the Sag River. ,In the event that the ,50 ft of cemented lap fails a pressure'test, 'tl~e lap, will be either cement squeezed' or the 2 7/8" liner top PBR willie utilized for the installation of a.2 7/8" extension with a retrievable:liner top packer set in the 4 ~" tubing. This extension with packer w0uld, b~ retrieved to provide access fo~ a future sidetrack. A schematic drawing of the proposed 50 f~ lap and contingency liner, top,packer is attached for reference.

Since that time the sidetrack has been re-evaluated, and.'the directional plan has changed. This change eliminates an upstructure intermediate target but leaves the final downstructure target at TD unchanged. The TD location is essentially unchanged ,,but the path to be taken to TD has changed. The original directional plan, as permitted, is attached for reference along with the new directional plan.

The sidetrack, S-08a, will target attic oil in Zone 4. This sidetrack will be conducted in two phases. Phase 1: set whipstock and downsqueeze abandonment cement: Planned for 11/10/98. · S-08 has passed a mechanical integrity test. The well has been drifted and a Kinley caliper has been run. A final Schmoo-B-Gone treatment will be pumped prior to setting the whipstock. · A permanent whipstock will be set on ELine at approximately 8,975' MD. · Existing perforations will be abandoned with approx. 15 bbls cement. Abandonment cement will be downsqueezed past the whipstock and squeezed to 1500 psi with AC)GCC witness. This procedure is described in more detail in the Form 10-403. Phase 2: Mill Window and Drill Directional Hole: Planned for 11/18/98. Directional drilling coil tubing equipment will be rigged up and utilized to mill the window (if not done by service coil) and drill the directional hole as per attached plan. The completion will be a fully cemented 2 7/8" liner. Mud Program: - Phase 1: Seawater - Phase 2: FIo-Pro (8.8 - 8.9 ppg) Liner Program: - 2 7/8", 6.16#, L-80, ST-L liner will be run from TD to approx. 8,291' MD and cemented with approx. 26 bbls. cement. The well will then be perforated with coil tubing conveyed guns. Well Control: - BC)P 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: 8,975' MD (8,585' TVD ss) - TD: 11,675' MD (8,799' 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. · Phase resistivity log will be run in open hole prior to running the liner. Mud and Cuttings disposal: All waste mud and cuttings will be injected at the CC2 facility. Drilling Hazards: No faults are lost circulation zones are expected on this sidetrack.
