G-18A was a coil sidetrack in May 1999. G-18A has been a fairly low on-time cycle/swing well for the past 4-5 years due to high GOR. It has been shut in since 12/25/13. The well was evaluated for a potential CTD sidetrack, but due to cement/fill at the top of liner a cut and pull of the existing 2-7/8" liner is deemed a low chance of success. Reason for Sidetrack: Due to the low on-time cycle/swing for the past 4-5 years from high GOR and lack of CTD sidetrack feasibility, the best use for this well is as a rotary sidetrack to a new I. location. f.

Alaska Oil and Gas Conservation Commission 333 West 7th Avenue Anchorage, Alaska 99501 V "� Subject: Corrosion Inhibitor Treatments of GPB G -Pad 1 Dear Mr. Regg, Enclosed please find multiple copies of a spreadsheet with a list of wells from GPB Pad G that were treated with corrosion inhibitor in the surface casing by conductor annulus. The corrosion inhibitor is engineered to prevent water from entering the annular space and causing external corrosion that could result in a surface casing leak to atmosphere. The attached spreadsheet represents the well name, API and PTD numbers, top of cement depth prior to filling and volumes of corrosion inhibitor used in each conductor. As per previous agreement with the AOGCC, this letter and spreadsheet serve as notification that the treatments took place and meet the requirements of form 10 -404, Report of Sundry Operations. If you require any additional information, please contact me or my alternate, Gerald Murphy, at 659 -5102.

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. previousmonths test~due~o~ 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~wel/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.

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 IA, 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.

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. 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 witness a test of BOPE installed prior to drilling new hole.

The sidetrack, G-18a, will target mid Zone 2. This sidetrack will be conducted in two phases. Phase 1: Set whipstock: Planned for April 2, '1999. · An inner annulus pressure test has been performed. A Kinley caliper will be run over the tubing and liner. · A permanent whipstock will be set on ELine at approximately 10090' MD, 69ft above the top existing perforation. Phase 2: Abandon Perfs, Mill Window and Drill Directional Hole: Planned for April 5, 1999. Directional drilling coiled tubing equipment will be rigged up and utilized to abandon perfs, mill the window and drill the directional hole as per attached plan to planned TD of 11,871' MD (8,961' TVDss). Mud Program: - Phase 1: Seawater · Phase 2: Seawater and FIo-Pro (8.8 - 8.9 ppg) Disposal: - No annular injection on this well. - All drilling and completio fluids and all other Class II wastes will go to CC-2a for injection. - All Class I wastes will go to Pad 3 for disposal. Casing Program: - 2 7/8", 6.16#, L-80, ST-L liner will be run from TD to approx. 9175' MD and cemented with approx. 21 bbls. cement to bring cement 200 ft above the window. The well will then be perforated with coiled 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: 10,100' MD (8,739' -I-VD ss) - TD: 11,871' MD (8,961' TVD ss) - Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run.
