Proposed plan: Prior to drilling activities, screening will be conducted to drift for whipstock and caliper. A coil tubing drilling sidetrack will be drilled with the Nabors CDR2 or CDR3 rig. The rig will move in, test BOPE and kill the well. The rig will set the 4-1/2"x9-5/8" whipstock and mill a single string 3.80" window + 10' of formation. The well will kic k off drilling in the Shublik and land in Ivishak Zone 2. The lateral will continue in Zone 3 and 2 to TD. The proposed sidetrack will be completed with a 3-1/2"x3-1/4"x2-7/8” 13Cr solid liner, cemented in place and selectively perforated post rig (will be perforated with rig if unable to post rig). This completion will completely isolate and abandon the parent Prudhoe Pool perfs. 20 AAC 25.112(i) Variance Request: Hilcorp requests to plug the existing perforations via the liner cement job, packer whipstock and/or liner top packer, if the liner lap pressure test fails as an alternate plug placement. 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.

The well exhibited a higher than anticipated watercut. A lab sample indicated Barium. The live gas lift valves were swapped to dummies. An IA leak was found with a LLR of 0.4 BPM at 780-psi. An LDL confirmed a PC leak at 5,450ft @ An MIT-T passed to 2344 psi on 12/23/22. Status Currently classified as Not Operable by Hilcorp due to the PC leak. Objective Current production from 01-31 is approximately 800 bopd at 85 mscf/stb yielding an incremental oil rate (IOR) of ~120 bopd at the marginal GOR of ~100 mscf/stb at FS1. Production from the current completion in Ivishak Zone 4 rich gas is not mature enough, with only 3 weeks of production to establish a decline rate. Based on analogous wells’ Zone 4 rich gas production trends, remaining incremental recovery from 01-31 is anticipated to be 10-20 mbbl from Z4 and insufficient to support the cost of RWO and scab liner. Repairing the well with an IA cement job is estimated to provide an incremental 140 IOR. Without an IA cement repair the well has no utility in the foreseeable future. The proposed TOC the IA is ~4,500’ MD which is greater than 1500’ TVD below the SC shoe and ~262’ shallower than the estimated top of the UG4 marker @ ~4,762’ MD. This TOC will cover the PC leak at ~5,450’ MD and will meet the regulatory requirements of CO 736. Post-job Evaluation o MIT-T and CMIT-TxIA o SCMT to confirm the Top of Cement (TOC) Long-Term Integrity Monitoring o Biennial MIT-T and CMIT-TxIA o Monitor and Record WHPs daily * SCMT to AOGCC for cement quality/continuity evaluation along cement packer length. 2 Procedural steps Slickline 1.Pull Tubing Tail Plug. 1. Set 4-1/2” CBP just above the production packer. 2. PT of tubing/CBP to 1500 psi to verify CBP set. Five minute test, no more than 10% pressure loss. 3. Pull lower station dummy valve at 8,596’. 4. Pump diesel down the tubing while taking returns up the IA, to confirm circulating rates and pressures through tubing punch. Circulate tubing and IA to diesel. 5. Set 4-1/2” cement retainer in the joint of tubing above the GLM. Fullbore 1.

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. Sincerely, Mehreen Vazir BPXA, Well Integrity Coordinator • • BP Exploration (Alaska) Inc.

The drilling contractor was in the process of nippling up. The test commenced at 2:00 p.m. and was concluded at 3:10 p.m. There was one failure. A valve on the choke manifold system leaked. Bob Newman called the AOGCC office on July 15, 1986 at 8:30 a.m. and said the valve was repaired and tested to 5000 psi. I filled out the AOGCC BOP inspection report which is attached.

The permit to drill does not indemnify you from the probable need to obtain additional permits required by law from other governmental agencies prior to commencing operations at the well. site. 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. %~ere 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.
