Request: Abandon Reason for Sundry Application: As part of the rig sidetrack operation, the existing W-19A perforations and W-19AL1 slotted liner will be permanently abandoned as follows: W-19A P&A: A cement retainer will be set in the 4-1 /2" liner below the window for the AL1 lateral. 50 bbls of 15.8 ppg Class G cement will be pumped through the cement retainer by means of coil. The cement will be placed /squeezed into the W-19A lateral and 1 bbls will be laid on top of the cement retainer. The cement plug will be pressure tested to 2000 psi. W-19AL1 P&A: 34 bbls of 15.8 ppg Class G cement will be placed in the AL1 lateral by means of coil. A TOC will be targeted at 10,000' MD. Reason for Sidetrack: W-19A and W-19AL1 is shut in due to hi h water cut. In addition, a tubing caliper indicated that the tubing was generally in poor condition with posse le buckled tubing. This prevents the option of a coil sidetrack. Current Status: W-19A was drilled in 1998 with IP = 700 BOPD with 45% WC. W-19AL1 was drilled in March 2003 with incremental production of 300 BOPD with 95% WC. Average production in 2006 was 190 BOPD with 95% WC. A patch was installed across W-19AL1 in 2007 to see what W-19A could produce. The 2007 average production was 24 BOPD with 99% WC. A MIT-IA passed to 3000 psi on 2/16/2003. A MIT-OA failed on 2/14/2003 with a LLR of 2 bpm at 1200 psi. The tubing has had no pressure tests since completion. A caliper run on 5/8/2007 indicates up to 80% penetration at 6499' MD. 50% tubing penetrations over half of the tubing string with less than 10% body metal loss.. The caliper also seemed to indicate buckled tubing from 7500' -10600' MD. Other Requests: Given rig floor height limitations, a MASP < 3000 psi, and the fact that the three ram drilling BOP configuration is preferred to a two ram configuration with a spool, BPXA will execute the provisions of 20 AAC 25.285 (f) (1) regarding the initial testing of the ROPE as follows when existing wellhead or testing equipment prevents the testing of the lowest set of pipe rams: That lowest set of rams will be tested at the earliest opportunity during path-forward de-completion work, i.e., after the completion has been pulled from the well. Safety concerns and spacing limitations with the wellhead height and tubing spool preclude us from installing a spacer spool in the three-ram drilling BOP stack. Scope of Work: Pump 50 bbls of cement through a cement retainer to P&A W-19A. Squeeze 34 bbls of cement into the W-19AL1 lateral, targeting a TOC at 10,000' MD. Cut and pull the 4-1/2" L-80 completion. Cut and pull the 9-5/8" L-80 intermediate casing.

Well PBU W-19A & W-19AL1 AOGCC Permits 198-069 & 202-235 Requested Action: BP Exploration (Alaska) Inc. (BPXA) proposes to abandon the subject wellbores to prepare the well for a rig sidetrack. Recommendation: I recommend approval of Sundry Applications 310-148 and 31-149 to allow BPXA to perform this operation. Discussion: BPXA proposes to plug the subject wellbores to prepare the well for sidetracking. The W-19A well was brought on production in January 1999 and the W-19AL1 well was brought online in March 2003. The W-19A well produced approximately 280 MBO before the W-19AL 1 lateral was added to the well. Prior to drilling the lateral the well was producing approximately 150 BOPD at a water cut of approximately 75%. After completion of the lateral production increased to approximately 450 BOPD but water cut also increased to approximately 85%. Production decreased and water cut increased steadily until November 2004 when oil production increased and water cut decreased dramatically apparently because an FOR gas slug reached the well. This is evidenced by the fact that the gas rate went from approximately 700 MCFPD to over 3,000 MCFPD in one month and continued to climb for several months peaking at just under 13,000 MCFP before dropping back to pre-slug levels. Also, during this time the well was switched from gas-lift to naturally flowing which is further evidence of a gas slug reaching the well. The elevated production lasted until about September 2005 when oil and gas production and water cut returned to earlier levels. The well remained on regular production until July 2006 at which time production was running about 150 BOPD and the water cut was over 95%. A couple of short attempts, totaling 34 days, have been made at restoring production from this well but oil rates have remained low and water cuts have remained over 95%. Cumulative production from this well is approximately 681 MBO. Conclusion: Plugging these wellbores so a new wellbore can be drilled to a more favorable location appears to be the prudent choice for this well. Therefore, l recommend approving BPXA's requests.

This permit to redrill does not exempt you from obtaining additional permits or approvals required by law from other governmental agencies, and does not authorize conducting drilling operations until all other required permits and approvals have been issued. In addition, the Commission reserves the right to withdraw the permit in the event it was erroneously issued. The permit is for a new wellbore segment of existing well PBU W-19A, Permit No 198-199, API 50-029-22006-01. Production should continue to be reported as a function of the original API number stated above. Operations must be conducted in accordance with AS 31.05 and Title 20, Chapter 25 of the Alaska Administrative Code unless the Commission specifically authorizes a variance. Failure to comply with an applicable provision of AS 31.05, Title 20, Chapter 25 of the Alaska Administrative Code, or a Commission order, or the terms and conditions of this permit may result in the revocation or suspension of the permit. Please provide at least twenty-four (24) hours notice for a representative of the Commission to witness any required test. Contact the Commission's North Slope petroleum field inspector at 659-3607 (pager). Sincerely, ~ð-~ Michael L.

The coiled tubing sidetrack, W-19AL 1, will exit the 4- 1/2" liner in the Sag River formation and target upper Zone 4. Prior to CTD sidetracking the well, a retrievable through tubing whipstock and retriev~le packer will be set. The XN nipple and window will be mi lied with coil. Approximately 2280' of 3-3/4" open hole is planned to açcess the Ivishak, Zone 4 target. The well will be completed with an un-cemented, solid and slotted line~Once the liner is in place the whipstock and packer will be retrieved in order to retain production from the existing perforations.

Drilling coil will then drill and complete the directional hole as per attached plan. Maximum hole angle is planned for 96 degrees. The lateral will be completed with a 2 7/8" x 33/16" 1'/ un-cemented solid and slotted liner. The liner top will be left outside the window. Resistivity logs will be run in the open hole in addition to MWD gamma ray. Finally, the whipstock and bridge plug will be retrieved. Mud Program: · Phase 1: 2% KCI and 2ppb Biozan for milling."., · Phase 2: Drill with Flo-Pro (8.6 - 8.7 ppg) ," Disposal: · All drilling and completion fluids and all other Class \I wastes will go to Grind & Inject or Pad 3. · All Class I wastes will go to Pad 3 for disposal. Casing Program: /i The production liner will be 27/8" ST-L slotted liner from TD to approx. 11,100' MD, where it will be crossed over to solid 3 3/16" liner. Desired top of 3 3/16" liner will be at approx. 1 O,950'md left outsid~~ the window. Leaving the lateral liner outside the window will preserve access to the existing perforations. Use of the 3-3/16" liner will preserve future sidetrack options. Well Control: · BOP diagram is attached. /' · Pipe rams, blind rams and the CT pack-off will be pressure tested to 400 psi and to 3500 psi. · The annular preventer will be tested to 400 psi and 2500 psi. Directional · See attached directional plan, 2280' planned horizontal. Max. planned hole angle is approx. 96deg. · Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. Logging · An MWD Gamma Ray will be run over the entire open hole section. Resistivity will also be. run in the open hole.
