The OA was cemented to surface as part of the sidetrack work scope. The OA exhibited re-pressurization although the gas samples from the IA and OA were dissimilar, indicating a shallow hydrate as the possible source of OA pressure. In November of 2016, the NOL (Normal Operating Limit) was raised to 1,600 psi and the well was made Operable. It produced for much of 2017 and did not require frequent bleeds to keep the OA pressure under NOL. In January of 2018 when the well was brought online, it exceeded NOL with an OA pressure of ~1,650 psi. The OA had to be bled multiple times over multiple days to keep the OA pressure below NOL. Gas samples from the IA and OA were taken again for analysis with the same dissimilar results. WellLock was squeezed into the OA May 2018 and was successful at sealing off the OA from repressurizing above NOL. The well continued to produce until February 2020, when it became uncompetitive. In preparation for planned well work, the L-01A was POP’d on 6/15/2023 for testing and evaluation. While bringing the well online, gas bubbling from the conductor was observed. The well was shut-in and LEL readings were found to be over limit. Objective: This procedure is to clean out the Conductor and top off the Conductor x 9-5/8” Annulus with cement to seal- off the gas bubbling from the conductor. Procedural Steps: Slickline – 1. Set tubing tail plug and CMIT-TxIA to 3,500 psi. 2. Pull tubing tail plug. DHD/Special Projects – 1. Hot water/surfactant/steam wash the Conductor x 9-5/8” Annulus to top of good cement. 2. Top off Conductor with cement. DHD – 1. POP well Under-Evaluation and monitor conductor/cellar for any bubbling/gas. Attachments – x Current Wellbore Schematic x Approved Sundry Change Form Gas samples from the IA and OA were taken again for analysis with the same dissimilar results.W indicating a shallow hydrate as the possible source of OA pressure.

Diagnostic work performed during the UE period does not indicate IAxOA communication, however the OA pressure did not stabilize and required numerous bleeds to maintain below NOL. At this time the well is reclassified as Not Operable and will remain shut in due to unmanageable OA repressurization while online. The engineering team is currently evaluating the well for an OA down squeeze repair.

Repressurization of the small void at the top of the OA has recurred since the annulus was cemented during a rotary sidetrack in February 2015.At this time,the repressurization is not manageable by bleeds. Diagnostics indicate that the most likely source is a shallow gas hydrate zone.The OA pressure stabilizes between 1000- 1200 psi. L-01A is a candidate for a revised (increased) OA NOL,and this option will likely be pursued.Once the BPXA internal process is completed,AOGCC approval will be sought prior to revising the NOL. The well is reclassified as Not Operable while the NOL revision is progressed.

Ken Bulloch / Scott Bundy; AK, D&C Special Projects tri Tyler Norene / Len Seymour; AK, D&C Well Services Team Lead Date: 04-24-2015 From: Jessica Sayers, Well Integrity/Intervention Engineer (office: 564-4281, cell: 602-8715) Subject: L-01 WeIlLock MicroOA Treatment Objective This program is for treating the micro-annular leaking in the fully cemented OA. This well exhibits OA repressurization when on production and is not manageable by bleeds. WeIlLock is a Newtonian resin that sets with temperature as an inert, hard, plastic-like material. The viscosity has been tested at 60 cP. The objective is to use the small diaphragm, suitcase, pump to squeeze the WeIlLock into the micro-annulus with high pressure and low volume. OA valves will be serviced to keep WeIlLock from setting up. Well Detail Current Status: Not Operable — PAL Previous Test: 04-04-2015 MIT-OA passed to 1200psi Integrity Issues: Fully cemented OA, OA breaks MOASP, unmanageable by bleeds when on-line (all gas) Last H2S Reading: 05-07-2010 20 ppm Well Operation Detail Fluid Density: WeIlLock: 9.1-9.3 ppg (keep WeIlLock at or above 85°F) Musol A: 7.5 ppg 2% KCI: 8.3-8.5 ppg Diesel: 6.8 ppg Equipment: See rig-up diagram Temperature: Maintain 75°-80° F throughout the entire job Relevant History: > 02/19/15: RWO sidetrack complete > 04/04/15: Pull plug @ 10857' MD, Set LGLV, MIT-OA Passed to 1200 psi Well Program: • 1 D Pump 580 bbls hot, 180° F, crude down IA to heat up the OA. 2 D Evacuate OA void with triplex. 3 D * Switch to diaphragm pump. Pump WeIlLock. Take returns 1:1 in grounded bucket. 4 D Maintain 2500 psi for two. This is to squeeze the WeIlLock into the microannulus. Record pressure and temperature readings on casing every hour. 5 D Service valves and clean with Nitrogen and Musol A, if needed. 6 D Shut-in suitcase pump and returns. 8 D Leave pressure on well for one week. 9 D Leave crystal gauge on well and take pressure and temperature readings on casing, twice daily. Record in AWGS. 10 D After seven days, MIT-OA * Collect approximately one cup sample of WeIlLock in disposable container. Place sample in representative condition and monitor viscosity throughout job.

During the course of the workover process,the outer annulus pressure has risen to a range of 900-1000 psi, with gas samples still indicating the pressure is coming from an external source (98-99%methane).The well has been reclassified as Not Operable until additional diagnostics can be performed to determine well integrity. Plan Forward while Not Operable: 1. DHD: Monitor OA, determine stabilization pressure 2. DHD: MIT-OA, LLR as needed 3. WIE: additional diagnostics as needed Once these diagnostics have been performed, the well will be brought online Under Evaluation to determine what mitigation is necessary for continued well operation.The outer annulus pressure will most likely exceed MOASP (1,000 psi) while determining the stabilization value. Should this value approach 2,000 psi, the OA will be bled off, and a new approach developed. Please call with any questions.

Pump pressure increased to 1900 psi when the pack-off released. The displacement continued with full returns.Total loss of mud was 10 bbls. Seepage/Loss rate before the job was 20 bbl/hour. We ran a USIT to verify isolation between permeable zones. Our Petrophysicist evaluated log confirming zonal isolation.

Pump pressure increased to 1900 psi when the pack-off released. The displacement continued with full returns.Total loss of mud was 10 bbls. Seepage/Loss rate before the job was 20 bbl/hour. We ran a USIT to verify isolation between permeable zones. Our Petrophysicist evaluated log confirming zonal isolation. Results attached. We are proceeding with operations to drill production hole as per Permit to Drill. Thanks,Troy Troy Jakabosky Drilling Engineer bp 900E.

The rotary sidetrack is a horizontal Ivishak producer. L-01 will be abandoned and tubing jet cut pre-ng: The 4-1/2" tubing will then be pulled with the rig. 7" casing will be cut and pulled. A whipstock will be set in the 9-5/8" casing at-2,710'. The intermediate hole is planned as a liner with the shoe set in the top of the Sag River Formation. The production interval will be completed with a.eementedrdperforated liner. IinCGv,t✓tc4' S/r�/��r S/c<v<s t.-/ i f1� The maximum anticipated surface pressure from the Ivishak/Sag with a full column of gas from pu`kc`-:, TD to surface is -2,999 psi (assumes 8.6 ppg as max pore pressure and 0.1 psi/ft gas gradient).
