On 9/23/24 the OA began to rapidly repressurize and exceed MOASP. The OA of B-36 was cemented to surface on 9/13/08 as part of a RWO to repair a SC leak. Since the OA was cemented, it has seen periods of OA repressurization. Due to this, the OA was Wellocked on 10/11/2019 and again on 9/19/2021. Current Status: B-36 is currently under evaluation starting 09/23/2024. Scope of Work: Squeeze OA with Well Lock (or similar) to repair OA repressurization.

Latest perforations gas’d out immediately with gas increasing from pre plug/perf rate of 23 MMSCFD to 36 mmscfd. A bond log is needed prior to proceeding with next stage of perforations to confirm isolation from high GOR toe perfs. Objective:Log CBL to confirm isolation between pevious and proposed perfs. Utilize CTU to isolate existing perforations then surface deploy TCP guns with CTU to add new perfs and improve GOR. Sundry Procedure (Approval Required to Proceed): Note: The well will be killed and monitored before making up the extended perfs guns. This is generally done during the drift/logging or plug set run. This will provide guidance as to whether the well will be killed by bullheading or circulating bottoms up throughout the job. If pressure is seen immediately after perforating, it will either be killed by bullheading while POOH or circulating bottoms up through the same port that opened to shear the firing head.

The reason for this denial is the AGOCC will require recent TIO plots, an OA injectivity test, and another MIT -IA (or CMIT TxIA) before placing well lock in the OA in a manner that could mask communication to the OA (surface and/or shoe) from the IA. This denial is without prejudice to your right to resubmit an application in the future if you are able to provide the necessary supporting information. As provided in AS 31.05.080(a), within 20 days after written notice of this decision, or such further time as the AOGCC grants for good cause shown, a person affected by it may file with the AOGCC an application for reconsideration. A request for reconsideration is considered timely if it is received by 4:30 PM on the 23rd day following the date of this letter, or the next working day if the 23rd day falls on a holiday or weekend. A person may not appeal an AOGCC decision to Superior Court unless reconsideration has been requested. Sincerely, Daniel T. Seamount, Jr. Commissioner DATED this 2-o dray of February, 2019.

Attachm is in Duplicate / Z f5 -/j• by la^ k*j Well: B-36 B-36 OA WeIlLock Squeeze Well Interventions Engineer: Katherine O'Connor (907) 564-4640 Pad Engineer: Wade Boman (907) 564-4674 Expected Start Date: March 1, 2019 History B-36 is a naturally producing well. In 2008 a RWO cut & pulled the PC and cemented the OA to repair a surface casing leak. The well was on a on/off production cycle, and the last time the well was "on" (Nove 2018 — Jan 2019) there was rapid OA repressurization. This well was monitored for repressurization trends, and on 2/3/2019 the well was put under evaluation with T/I/O of 2130/290/790 psi. The well passed PPPOT-T and PPPOT-IC tests, indicating the communication is not through the well head. The plan forward is to complete a WeIlLock treatment — squeezing the WeIlLock into the cemented OA to mitigate repressurization. Pending a successful squeeze, the well can be brought back to operable status. Current Status The well is currently under evaluation and will be soon shut-in and classified as "Not Operable" by BP. Objective Squeeze the cemented OA with Well Lock to seal off the OA re -pressurization. Procedure 1. ND OA Gate Valve, NU OA Integral, 2. Bleed Annuli, Prep OA, WeIlLock OA top job squeeze to 2500 psi per RPs. 3.

Coil tubing unit will set a CTD whipstock. CDR 2 will mill a 3.80" window in the 4-1/2" liner and drill an Ivishak well to —13,671 ' MD. The lateral will be completed with a 3-1/2" x 3-1/4'x 2-7/8" 13Cr-80 liner which will be cementedand perforated. The following describes work planned and is submitted as an attachment to Form 10-403. A schematic diagram of the current wellbore and proposed sidetrack is attached for reference. CTD Drill and Complete B -36A program: Rip Start Date: July 1st 2017 Pro -Rig Work scheduled to begin May 15th, 2017 C 1 Mill N. Set Snap Lock Orienter, Set Whipstock V 5 Set TWC. CTD Tree Work Rig Work: 1. MIRU and test BOPE. Maximum expected surface pressure with gas (0.10 psi/ft) to surface is 2,421 psi. 2. Mill 3.80" window plus 10' of rathole. Swap the well to 8.5-9.5 ppg drilling fluid. 3. PU drilling BHA with GR/Resistivity 4. Drill 4.25" hole to TD. 5. Run 3-1/2"x3-1/4" x 2-7/8" 13CR-80 liner. 6. Pump primary cement bringing TOC to TOL, 29 bbls of 15.3 ppg liner cmt planned* 7. Freeze protect well, RDMO Post Rig: 1. V: Tree work as necessary. 2. F: Liner Lap Test 3. C: RPM and Perforate 4.

Hole size: 4.25" Liner Program: • 3-1/2", 9.3# 13Cr-85 STL Liner 11,000 MD - 11,500 MD • 3-1/4", 6.5# 13Cr-85 TCII Liner 11,500 MD — 11,900 MD • 2-7/8" 6.4# 13Cr-85 STL 11,900' MD- 13,671 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. • Magnetic and inclination surveys will be taken every 30 ft. • Distance to nearest property — 27,158 • Distance to nearest well within pool - 70'(B -27C) Logging 0 MWD directional, Gamma Ray and Resistivity will be run over all of the open hole section. Perforating: • 2" guns, 6 spf, pert guns • 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 / • There are no wells that fail "Major Risk" with the B -36A wellpath. ✓ Hazards % • DS B -pad is an H2S pad • Low Risk of lost circulation • No anticipated fault crossing Reservoir Pressure • The reservoir pressure on B -36A is expected to be 3318 psi at 8977' TVDss. (7.11 ppg equivalent). • Maximum expected surface pressure with gas (0.10 psi/ft) to surface is 2,421 psi. Managed Pressure Drilling ✓ • MPD techniques may be used to improve hole stability. • An automatic choke will maintain a target ECD at the window for the duration of drilling to improve hole stability. • A pressure schedule will be used for tripping In/Out of the hole. The purpose of the pressure schedule for tripping is to maintain the same bottom hole pressure at the window by applying surface pressure via the choke. • At all times, drilling fluid weight will be greater than equivalent pore pressure. MPD is only being used for hole stability.
