All, Well X-31 L 1 (PTD #2020730) has sustained casing pressure on the IA and has been classified as a Problem well. A TIFL failed on 10/14/06. TIO's on 10/14/06 are 2120/2120/100. The plan forward for this well is as follows: 1. SL: CO OGLV 2. DHD: Re-TIFL Attached is a wellbore schematic. Please call with any questions. «X-31 L 1.pdf» Joe Anders, P.E.

On 10/14/06 DHD performed a TIFL that failed. To mitigate this TxlA comm I suggest we change out the SO in station # 1 and re-TIFL to establish tubing integrity. I have updated AnnComm to mirror this suggestion, however, I have not swapped the status from Normal to Problem. Let me know if you have any questions or concerns.

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. The permit is for a new wellbore segment of existing well Prudhoe Bay Unit X-31, Permit No. 198- 198, API 50-029-22435. Production should continue to be reported as a function of the original API number stated above. Blowout prevention equipment (BOPE) must be tested in accordance with 20 AAC 25035. 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.

Pressure test tree and valves. Prep - detailed below is planned to start March 22"d, 2002 Drift with service coil / Set a 4%" monobore flow-through whipstock at 12750' md, (-8,938' tvdss). . . I Phase 2: Drill and Complete CTD si~etrack: Planned for March 31th, 2002. 2%" coil will be used to drill a -1425ft of 3%" OH sidetrack from a window cut in the 4-1/2" liner - as per the attached plan. The sidetrack will then be completed with an uncemented solid & slotted liner. Mud Program: . Phase 1: Seawater / . Phase 2: Seawater and Flo-Pro (8.6 - 8.7 ppg) Disposal: / .
