An MIT-OA to 1800 psi passed on 12/15/2024. The IA and OA pressure were then monitored for 30 days and showed stability with the injection rates. CPAI intends to return the well to normal status. The TIO plot, schematic, and bleed log is attached. Please let me know if you have any questions or disagree with this plan. Thanks, Jaime From: Well Integrity Specialist CPF2 Sent: Monday, December 9, 2024 1:10 PM To: Wallace, Chris D (CED) <chris.wallace@alaska.gov> Cc: Livingston, Erica J <Erica.J.Livingston@conocophillips.com> Subject: KRU 2K-24 (PTD 189-130) Possible Charging OA Hi Chris, KRU 2K-24 (PTD 189-130) is a water injection well currently on produced water injection that is showing signs of a charging OA. The build up rate is currently 3 psi/day and the OA pressure is currently sitting at 325 psi. CPAI intends to conduct surface casing diagnostics to confirm the integrity of the OA. Please let me know if you have any questions or disagree with the plan.

History and current status: Z-17 was drilled and completed in January, 1990. The well was re- perforated in 1991 which resulted in fracturing of the well. Well continued on decline with no interventions until 1998 when Z-02 exploded and almost all Z-pad wells were SI. Upon return to production in 2000 the well had problems with staying online due to low fluid rates and hydrate issues. The well endured a good amount of SI time between 2000 and 2010 due to hydrates. In 2007, a coil cleanout and mud acid stimulation was completed in an attempt to increase productivity, however it did not work. There are no remaining non-rig intervention options to return the well to ✓ competitive status. Proposed plan: Sidetrack Z-17 to the Z-17A location using Nordic 1 Coiled Tubing Drilling rig on or around October 15th, 2013. The Z-17A sidetrack will exit the existing 5-1/2" liner and kick off in the Shublik formation and land in Zone 4. This sidetrack will be completed with a 3-1/4" L-80 x 2-7/8" 13CR liner which will be cemented in place. This Sundry covers plugging the existing Z-17 perforations via a liner top packer(alternate plug placement per 20 AAC 25.112(i)). The following describes work planned and is submitted as an attachment to Form 10-403. A schematic diagram of the proposed sidetrack is attached for reference.

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.

Supervisor FROM: Lou Gdmaldi, DATE: April 21, 2001 SUBJECT: Petroleum Inspector SVS Tests BPX Z-pad Prudhoe Bay Field Saturday, April 21, 2001; I witnessed the three-month SVS retests on BPX Z pad in the Western Operating Area of the Prudhoe Bay Field. Merv Liddelow performed the SVS tests today. The test results (one SSV Failure) are noted on the accompanied SVS test spreadsheet. All well houses were in "OK" condition. This was the first experience I have had with the new SV control system on Z pad and found it to operate quite well. The temperatures today were somewhat mild (+15)-and it remains to be seen how-they will hold up dudng next winter's cold season. Wells Z-5 and Z'8 had siow closing SSV's (+ 2 minutes), Merv called the Automation crew and these were being worked on before I left the pad. The pad is being used as a staging area for some pipeline fabrication and has some equipment and material stored on it. This was kept for the most part neat and orderly. SUMMARY: I witnessed the three-month SVS retests on Z pad in the Prudhoe Bay Field. 20 wells, 40 components, one failure, 2;4% 34 Wellhouse inspections, 'no problems.

Supervisor Jeff Jones, SUBJECT: Petroleum Inspector Safety Valve Tests Prudhoe Bay Unit Z Pad Friday, Janua.,ry,19. 2001: I traveled to BPX's Z Pad in the Prudhoe Bay Field and witnessed surface safety valve system testing. Merv Liddelow was the BPX representative in charge of testing. As the attached AOGCC Safety. Valve System Test Report indicates I witnessed the testing of 21 wells and 43 components with 6 failures. The pilot on well Z-03 failed to trip and the pilot on well Z-08 was frozen and once thawed it passed a retest but the SSV on this well had an unacceptable closure time (12-min.). The SSV on well Z-18 also had an unacceptable closure time (15-min.) and the SSV's on wells Z-22B and Z-24 failed to pressure test. The high failure rate on Z Pad requires it be placed on a 90- day test interval. Mr. Liddlow indicated to me today that all failures have been repaired except the slow SSV closure of wells Z-08A and Z-18. The hydraulic lines on these wells need to be flushed and he has arranged for the maintenance crew to perform the work. Weilhouse inspections were conducted on the 21 wells tested with no exceptions noted. Summa~: i witnessed SVS testing at BPX's PBU Z Pad. 21 wells, 43 components, 6 failures. 13,9% failure rate. 21 wellhouse inspections conducted.

Enclosed is the approved application for permit to drill the above referenced well. The permit to drill 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. To aid us in scheduling field work, please notify this office 24 hours prior to commencing installation of the blowout prevention equipment so that a representative of the Commission may be present to witness testing of the equipment before the surface casing shoe is drilled. Where a diverter system is required, please also notify this office 24 hours prior to commencing equipment installation so that the Commission may witness testing before drilling below the shoe of the conductor pipe.
