G-15A was sidetracked with coil in August 1998. The plan was to place a 1000' horizontal in Zone 1B with the option to climb into Zone 2A if necessary. The well ended up landing 12' deeper than planned and dipped into the HOT by about 2'. The well was inverted back up but they found poor quality sand for the first 900' of horizontal. The last 300' of Zone 1B looked to be reasonable sand quality. The well was TD'd in Zone 1B and a total of 525' of Zone 1B perforations were shot. The well tested poorly then died off and wouldn't flow even with PBGL. Oil samples showed 20° API gravity which is not surprising due to the proximity of the HOT. A "Schmoo Be Gone" treatment was performed in December 1998, hoping to clean up the wellbore, but it didn't help and the well was shut-in and freeze protected. 50 feet of Zone 1B perfs were shot January 2000. It quickly died off and the well began to cycle in mid 2001 and continued to cycle with reasonable on time (40%) until October 2005 when it was shut in for what we thought was TxIA. However, after re-energizing the packoffs in March 2007 (the TxIA leak turned out to be in the wellhead) the well became operable, only to be shut in for high GOR a month later. In September 2007 a CIBP was set closing off all of the open perforations and shot a 15' oil lens in Zone 2C. By February of 2008 all the remaining oil lenses were shot and the well shut in due to high GOR. REASON FOR SIDETRACK: G-15 does not cycle and the well is shut-in due to high GOR. Due to the low remaining value of this well and the lack of wellwork options, the well is recommended for a coil sidetrack. The proposed plan for G-15B is to drill a through tubing sidetrack with the SLB/Nordic 1 Coiled Tubing Drilling rig on or around July 15, 2008. The existing perforations will be isolated by a CIBP in the remaining 2 7/8" liner, as well as the liner cement job. The sidetrack, G-15B, will exit the existing 7" liner and kick off in Shublik C and land in Z1B. The following describes work planned and is submitted as an attachment to Form 10-403. A schematic diagram of the proposed sidetrack is attached for reference. Pre-Rig Work: (scheduled to begin on May 15, 2008) 1. O MIT-IA, -OA Passed 3/17/08 2. E Set CIBP at 9,580' in 2 7/8" liner 3.

This log was run to assess the condition of the 5.5" and 4.5" tubing with respect to corrosive and mechanical damages. The 5.5" tubing logged appears to be in good to fair condition with respect to corrosive damage, with a maximum-recorded wall penetration of 31 % in joint 84 at 3,485'. The damage appears mainly in the form of isolated pitting. No significant areas of cross-sectional wall loss are recorded. Light deposits are recorded in a number of joints, however no significant 10 restrictions are recorded in the 5.5" tubing logged. The 4.5" tubing logged appears to be in good condition with respect to corrosive damage. No significant wall penetrations, areas of cross-sectional wall loss, or 1.0. restrictions are recorded. Cross-sectional drawings of the most significant events recorded are included in this report. The distribution of maximum - recorded penetrations is illustrated in the Body Region Analysis Page of this report. 5.5" TUBING - MAXIMUM RECORDED WALL PENETRATIONS: Isolated pitting (31%) Jt. 84 @ 3,485 Ft.

It requires an annual passing NFT and CITOA. An MITOA passed on 7/4/05, but the NFT failed two times on 9/15 and 9/16. Both times we got FTS. The gas lift valves are all dummied and the well was secured with a TTP on 10/16/05. Because the well no longer meets its annual written waiver requirements, the waiver should be cancelled and the well status should be changed to Trouble. Please review and let me know your opinion.

As the attached AOGCC Safety Valve System Test Report indicates I witnessed the testing of 16 wells and 32 components with no failures. The surface safety valve on well G-03A closed rather slowly but passed: its pressure test. The wing valve on wells G-16 and G-18A had very slow leaks but did not prohibit a valid test of the surface safety valve. Well G-21 which:failed the previous months test~due-~-_a frozen pilot, has the new style insulation box in place and functioned properly. Merv Liddelow performed the testing today; he demonstrated good test procedures and was a pleasure to work with. A walk through inspection of the well houses on this pad was performed during the SVS testing with no problems noted. Well G-14A which was shut in at this time and not tested was found to have the new style insulation box on the pilot. This should fix the problems found on previous tests. Summary: I witnessed the one-month retest of the safety valve systems at BPXs G-Pad.

Merv Liddelow was the BPX representative in charge of testing and he performed the tests in a safe and proficient manner. Fifteen wells were tested with nine failures witnessed. The pilots on wells G-02A, G-1 lA, G-14A and G- 21A failed to operate properly. The SSV's on wells G-01A, G-02A, G-03A, G-09 and G-13 failed to close or failed to hold DIP. Wells G-03 and G-09 were shut in pending repairs. Mr. Liddelow indicated to me that ali other failures had been repaired and passed a retest within 24 hours. Fifteen well houses were inspected and slight crude oil leaks were noted on wells G-14 and G-16. Mr. Liddelow and his crew repaired these leaks immediately. The AOGCC test reports are attached for reference. SUMMARY: I witnessed SVS tests on 15 oil producing wells on BPX's G Pad in the Prudhoe Bay Field. 15 wells, 30 components tested. 9 failures: 30% failure rate. 15 well house inspections Attachments: SVS PBU G pad 3-26-01 JJ CC;: NO.N.~.CON FI.DENT.!AL SVS PBU G Pad 3-26-01 JJ Alaska Oil and Gas Conservation Commission Safety Valve System Test Report Operator: BPX Operator Rep: Merv Liddelow AOGCC Rep: Jeff Jones Submitted By: Jeff Jones Field/Unit/Pad: PBF/PBU/G-Pad Separator psi: LPS 152 Date: 3/26/01 HPS 649 ii ., i, . i i i Well Permit Separ Set L/P Test Test Test Date OiI, WAG, G13TJ, Number Number PSI PSI Trip Code Code ,.Code Passed GXSorCYCLE G201A 1931710 649 550 565 e 5 oIL G-02A '1950230 1'52 125: 145 1 5 .......

The permit to rcdrill 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 arc 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 wimess 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.

The sidetrack, G-15a, will target Lower Zone 2 / Upper Zone 1 reserves. This sidetrack will be conducted in two phases. Phase 1: Set whipstock and downsqueeze abandonment cement: Planned for 7113198. · G-15 will be tested for tubing integrity, drifted and a Kinley caliper run in the liner and tubing. · A permanent whipstock will be set on ELine at approximately 9800' MD. · Existing perforations will be abandoned with approx. 20 bbls cement. Abandonment cement will be downsqueezed past the whipstock and will be pressure tested to 1500 psi with AOGCC witness. This procedure is described in more detail in the Form 10-403. Phase 2: Mill Window and Drill Directional Hole: Planned for 712198. Directional drilling coiled tubing equipment will be rigged up and utilized to mill the window and drill the directional hole as per the attached plan. Mud Program: - Phase 1: Seawater - Phase 2: FIo-Pro (8.8 - 8.9 ppg) Casing Program: - 2 7/8", 6.16#, L-80, ST-L liner will be run from TD to approx. 8900' MD and cemented with approx. 20 bbls. cement. 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: 9821' MD (8,728' TVD ss) - TD: 11,426' MD (8,936' 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. · Memory CNL will be run in the liner prior to perforating.
