A leak detect log on 12/03/14 indicated a leak at the production packer. The well has two liner top packers. The planned repair for the production packer leak was to pull the uppermost liner top packer, and replace it with an extended liner top packer designed to straddle the leak, but a 2015 attempt to retrieve the liner top packer was unsuccessful. On 05/19/16, E-line set a CIBP isolating all perforations. The plan forward is to POP the well Under Evaluation and obtain well tests, in order to determine whether gas is leaking by the liner top packers. This will help determine accurate formation gas rates, and determine whether the well has future utility. The well is reclassified as Under Evaluation. Plan Forward: 1.

On 1/8/2018 slickline completed setting a tubing patch from 8805’-8830’ MD covering the known tubing leak. The well passed a CMIT-TxIA to 2,553psi on 01/06/2018 and MIT-T to 2,611psi on 1/8/2018. The passing pressure test confirms that well barriers has successfully been restored. At this time the well is reclassified as Operable. Please note that coil will need to complete milling the CIBP in the liner before the well can be brought online.

A leak detect log on 12/03/14 indicated a leak at the production packer. The well has two liner top packers. The planned repair for the production packer leak was to pull the uppermost liner top packer, and replace it with an extended liner top packer designed to straddle the leak, but a 2015 attempt to retrieve the liner top packer was unsuccessful. On 05/19/16, E-line set a CIBP isolating all perforations. The plan forward is to POP the well Under Evaluation and obtain well tests, in order to determine whether gas is leaking by the liner top packers. This will help determine accurate formation gas rates, and determine whether the well has future utility. The well is reclassified as Under Evaluation. Plan Forward: 1. E-line: Set CIBP at 9390’ MD – DONE 05/19/16 2. Operations: POP well for economic evaluation 3. DHD: Assist Operations with POP Please reply if in conflict with proposed plan.

Thanks, Kevin Parks (Alternate Whitney Pettus) BP Alaska-Well Integrity Coordinator G �A Global Wells �/�/ Organization Office: 907.659.5102 WIC Email:AKDCWelllntegrityCoordinator@bp.com From: AK, D&C Well Integrity Coordinator Sent: Sunday, August 30, 2015 11:22 AM To: 'chris.wallace@alaska.gov' • Cc: AK, D&C Well Integrity Coordinator Subject: G-15C (PTD #2141260) Monitor for inner annulus repressurization Chris, As per our conversation, producer G-15C (PTD#2141260) is a natural flow well that has possible tubing x inner annulus communication by the packer. BP would like to bring well on line for up to 28 days and monitor the inner annulus pressure.The well passed a CMIT T x IA to 2500 psi on 12/3/2014 and a MIT-IA to 2500 psi on 12-02-14. If we find that the well has inner annulus communication the plan will be to have coil to replace the liner top packer and replace it with an extended liner top packer. If permission is granted to produce the well for diagnostic evaluation, the inner annulus pressure will not be actively managed with the exception of compensating for annular fluid expansion while the well is reaching a thermally stable state. The inner annulus will not be allowed to exceed 2000 psi, and the outer annulus will not be allowed to exceed 1000 psi. If either of these pressures are reached during the well tests after the well is thermally stable the well will be shut in and well tests will be terminated. I have enclosed a copy of the wellbore schematic for reference.

This permit to drill does not exempt you from obtaining additional permits or an approval 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 AOGCC reserves the right to withdraw the permit in the event it was erroneously issued. Operations must be conducted in accordance with AS 31.05 and Title 20, Chapter 25 of the Alaska Administrative Code unless the AOGCC 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 AOGCC order, or the terms and conditions of this permit may result in the revocation or suspension of the permit.

The G-15C sidetrack will exit through the existing 3-3/16" liner and kick off in Zone 2C and target Zone 1B reserves. The proposed sidetrack is a -2,385' horizontal Ivishak / Zone 1B producer, which will access a -30 acre reserves target southeast of G-15B on G-pad. The lateral will be completed with a 2-3/8" L-80 liner which will be cemented outside the window and perforated. Rig Work(scheduled to begin October 1, 2014) % 1.

Disposal: • All Class I & II non-hazardous and RCRA-exempt drilling and completion fluids will go to GNI at DS 4 or Pad 3 at DS 6. • Fluids >1% hydrocarbons or flammables must go to Pad 3. • Fluids >15% solids by volume must go to GNI. • Fluids with solids that will not pass through 1/4" screen must go to GNI. • Fluids with PH >11 must go to GNI. Hole Size: • 3.25" from 9,835' MD to 12,200' MD Liner Program: • 2-3/8", 4.7 lb/ft, L-80, TH 511 liner with cementralizers 9,300' MD - 12,200' MD • A minimum of 12 bbls of 15.8 ppg cement will be used for liner cementing (TOC 10,130' MD). • The primary barrier for this operation: a minimum EMW of 8.4 ppg. • A X-over shall be made up to a safety joint including a TIW valve for all tubulars ran in hole. Well Control: • BOP diagram is attached. • Pipe rams, blind rams and the CT pack off will be pressure tested to 250 psi and to 3,500 psi. • The annular preventer will be tested to 250 psi and 3,500 psi. Directional: • See attached directional plan. Maximum planned hole angle is 91°, inclination at kick off point is 35°. • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • Distance to nearest property— 17,200'. • Distance to nearest well within pool— 132'. Logging: • MWD directional, Gamma Ray and Resistivity will be run over all of the open hole section. • Cased hole GR/CCL/RPM logs will be run. Perforating: • 1.56" 1606 PJ HMX, 6 spf perf guns, 1" CSH work string &2-1/16" CSH. • The primary barrier for this operation: a minimum EMW of 8.4 ppg. • A X-over shall be made up to a safety joint including a TIW valve for all tubulars ran in hole. Anti-Collision Failures: • G-10 Center to center: 210' —Abandoned • G-10B Center to center: 617' —Abandoned • G-15B Parent well at KOP • G-16 Center to center: 593' —Abandoned • G-16A Center to center: 172' — Producer to be shut-in • G-19B Center to center: 441'— Producer to be shut-in Hazards: • G Pad is not considered an H2S pad. • G-15B had 20 ppm H2S on 1/25/2014. • The lost circulation risk for G-15C is considered to be low with two planned fault crossings. Reservoir Pressure: • The reservoir pressure on G-15C is expected to be 3,258 psi at 8,800' TVDss (7.12 ppg equivalent). • Maximum expected surface pressure with gas (0.10 psi/ft) to surface is 2,378 psi. • An EMW of 8.4 ppg for this well will provide 586 psi over-balance to the reservoir.
