G-31A was sidetracked in May 1998 as a Zone 1 horizontal well. Approximately 1000' was drilled into Zone 1B with the last 500' being very poor quality. The well was kicked off with N2 after the rig perforated 300' of poor quality Z1B rock, then kinley buttons were set uphole to provide gas lift. Shortly after, two schmoo- be-gone (SBG) treatments were pumped into the well followed by a diesel/xylene wash to clean up suspected Moveable Heavy Oil. In 1999, 60 feet of adperfs were shot in clean sand which made a well out of it. Another 75' of adperfs were shot in Mar-2002, making the well more competitive. The well produced until Dec 2002, when it was shut-in for more then two years until a patch was placed over the leaking kinley buttons. The well came back making high GOR oil and started cycling about a year later. In September 2008, 20 feet of end-of-life adperfs were shot in the heel. The well showed to have improved slightly in the first cycle, but did not make a drastic improvement. There are no further options for this well. REASON FOR SIDETRACK Given the high GOR G-31 A is a good candidate for a coil sidetrack. ~~ The proposed plan for G-31A is to drill a through tubing sidetrack with the SLB/Nordic 1 Coiled ~~~~ Tubing Drilling rig on or around May 1, 2009. The existing perforations will be isolated by a CIBP, as ~„ oL well as the primary cement job. The sidetrack, G-31B, will exit the existing 7" liner after the 2-7/8" is cut and pulled. The following describes work planned and is submitted as an attachment to Form 10- 403. Aschematic diagram of the proposed sidetrack is attached for reference.

Supervisor DATE: April 24, 2001 FROM: Chuck Scheve; SUBJECT: Petroleum Inspector Safety :Valve Tests Prudhoe Bay Unit G-Pad Tue.sd.ay, April 24, 2001: I traveled to BPXs G Pad and witnessed the one-month retest of the safety valve systems. As the attached AOGCC Safety Valve System Test Report indicates ! 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.~o-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-t4A 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-11^, 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 D/P. 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.

The sidetrack, G-31A, will target Zone 1. This sidetrack will be conducted in two phases. Phase 1: Lay abandonment cement and set whipstock: Planned for 4~09~98. · A tubing integrity test will be performed. A dummy whipstock drift will be run prior to perforation abandonment. · Existing perforations will be abandoned with approx. 20 bbls cement. Abandonment cement will be pressure tested to 1500 psi and tagged with AOGCC witness. · A permanent whipstock will be set on ELine at approximately 8870' MD. Phase 2: Mill Window and Drill Directional Hole: Planned for 4118/98. Directional drilling coil tubing equipment will be rigged up and utilized to mill the window and drill the directional hole as per attached plan to planned TD of 10,073' MD (8,941' -I-VDss). 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. 7194' 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: 8918' MD (8,764' TVD ss) - TD: 10,073' MD (8,941' TVD ss) - Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run.
