On 1/7/2021 minor bubbling in the cellar was observed by the Drillsite Operator during the daily well inspection. LEL samples were taken and were within safe limits but the bubbling continued consistently. Subsequent diagnostics indicated that the well has a SC leak. An AOGCC witnessed MITT to ~2400 psi and an MITIA to ~2500 psi both passed on 11/16/2019. Current Status The well is classified as “Under Evaluation” and has a wireless gas head sensor installed at the floor grating level to continuously monitor LELs. Objective Pump sealant/cement down the OA to the SC leak and squeeze the leak off. Procedural steps DHD/Special projects 1. Top job the Conductor x SC with cement as deemed necessary. 2. Pump sealant (squeezecrete, Well Lock, or similar product) into the OA. 3. Squeeze sealant into the SC leak. 4. Monitor cellar for bubbling. 5. Re-treat OA with sealant/cement as required.

After several zonal modifications over the years, 11-31A was shut-in August 2005 because it couldn't compete with its gassier twin, 11-32, and was then brought back on production in August 2008 after 11-32 had a GSO and the two wells could flow together again. 11-31A was online for a few months before being SI for high watercut. Other zonal modifications have been attempted over the years, but high watercut has made 11-31A a typically uncompetitive producer. The current status of 11-31A is not operable. The well failed a CMIT-TxIA in March 2019. Following the CMIT-TxIA failure, a PC leak was identified at 6,016' MD. The well remains secured and isolated from the reservoir with a plug at 8861' MD. While the value of 11-31A would likely not justify remedial work, the IA cement job described here is being executed to restore the secondary barrier while preserving the option of producing the well at a later point if it becomes competitive to do so. Scope of Work: Repair production casing leak at 6016' MD with IA cement job. Background Information: • Production casing leak: o Initially discovered with failing CMIT-TxIA on 2/23/2019 o Temperature LDL on 3/4/2019 found leak depth to be 6016' MD • Cretaceous stratigraphy at 11-31A (Note: this was not logged directly in 11-31A, based on a conservative estimate of most -shallow occurrence seen in neighboring wells). o Top of UG4: 5547' MD, 5208' TVD. W az V6V2 Q"¢� P 67- fiat C -o 7 36� • SBHP on 4/20/2018 recorded pressure of 3352 psi equivalent at 8800' TVD datum, and temperature of 175 OF • 7-5/8" x 10-3/4" Outer Annulus has open shoe, and has never been pressure tested • TOC of the 7-5/8" casing is calculated at 7787' MD based on 300 sacks pumped with 30% hole washout Overview Procedure: Slickline and Fullbore: 1. Pull 4-1/2" PX plug from 8861' MD. 2. Run drift for CBP and cement retainer. 3. Set 4-1/2" CBP at 8792' MD in the first full joint of tubing above the packer. 4. Fire tubing punch from 8770'-8774' MD, across the collar at the top of the first full joint of tubing above the packer. a. Fullbore: pumping down the tubing and taking returns through the IA, confirm circulating rates and pressure through tubing punch. b. Circulate tubing and IA to diesel. 5. Set cement retainer at 8750' MD in the second full joint of tubing above the packer. Coiled Tubing: 1. Sting into cement retainer and pressure test. Pumping down coil, establish returns up the IA and pump the following schedule (target TOC in the IA is -5016' MD): / ) a. 5 bbl FW spacer �- �/©�O yH e'E r« ^ `j t f/SSC O b. 100 bbl Class G cement ('Sa,�L S� A, c. 5 bbl FW spacer T ��y U •J d.

Note pressures after un -stinging from retainer—do not bleed any pressure. Ensure that retainer is holding pressure, and then circulate or reverse the cement off the retainer and POOH. 3. Wait for cement to gain 500 psi of compressive strength and RIH with milling BHA and junk mill. Mill the retainer, cement, and CBP from the 4-1/2" tubing. Mill/push the remainder of the CBP until it is out of the tubing tail. Slickline and Fullbore 1. Set PX plug in X -nipple at 8861' MD. 2. Log SCMT. LCC- A aEVt-1GT5 TD �QdG-CC 3.

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, Torin Roschinger BPXA, Well Integrity Coordinator 1 BP Exploration (Alaska) Inc.

I. Supervisor FROM: Lou Grimaldi, ,~ SUBJECT: Petroleum Inspector THRU: State of Alaska Alaska Oil and Gas Conservation Commission DATE: December 14, 1996 FILE NO: AGGJLNDD.DOC BOPE Test Doyon .rig #14 Arco well #15-43 Prudhoe Bay Field PTD #96-183 Saturday, December 14, 1996: I witnessed the weekly BOPE test on Doyon rig #14 which was drilling Arco well #11-31A in the Prudhoe Bay Field. The rig was ready to test when I arrived. I toured the area surrounding the rig and found it to be kept clean and orderly. The test once started went well. The bottom Kelly valve had a small 'amount of leakage and will be repaired before the rig drills out. Two valves on the choke manifold leaked and had to have the stem travel adjusted. The lower pipe rams will be tested when the rig runs in to test the casing. This was necessitated due to interference of the tool joint in the ram path. This was caused by the need for a crossover for the 3 1/2 driilpipe and test plug that had a 4 1/2 box. I allowed for this alternative test after I was assured that a special test joint will be fabricated and kept on hand for the future. The upper Kelly valve will be tested when it is tightened after getting some pipe run. The rest of the BOPE tested out OK and ! found the upkeep of this rig to be good. SUMMARY:. I witnessed the weekly BOPE test on Doyon rig #14. There were three failures, test time four hours. Attachments: AGGJLNDD.XLS CC: Mike Miller/Randy Thomas (Prudhoe Bay drlg.)

The objective of the redrill is to access Zone I reserves. The objective of pre-rig work activity is to establish that the 10-3/4" by 7-5/8" annulus is open, P&A the existing wellbore perforations, and cut the existing 4-1/2" tubing in preparation for tubing removal. The well will be freeze protected following P&A activities to prevent freeze damage. Pre-Rig Operations: . Notify an AOGCC representative prior to beginning P&A operations. RU on the 7-5/8" by 10-3/4" annulus and pump in 20 bbl of diesel to verify that the annulus is open. 2. Check and service the wellhead, pressure test the 7-5/8" packoff to 3500 psi. . Kill the well with seawater. Estabilish injecfivity and cement the open peris at 11054'-11081' by pumping cement down the tubing, chase the cement with a wiper dart to remove residue in the tubing. (Consult with your cement contractor for best way to accomplish the wiper dart). If injectivity cannot be established it will be necessary to call out a coil tubing unit to accomplish the P&A. The capacity from the tubing tail at 10494' to the top of the cement plug at 11109' is 28.2 bbl, plan to pump about 20 bbl of cement to P&A the well. Verify the TOC with a wireline mn, If required by onsite AOGCC representative, pressure test the cement to 1500 psi. Tag and record the TOC. (minimum acceptable TOC is 100' above the top Of the perforated interval, top peffs are .11054'MD ) · Have an AOGCC representative on location during testing and tagging operations. . Make a jet cut of the 4-1/2" 13CR tubing at 10390'+ at one joint above the packer. RU and reverse circulate through the jet cut with seawater until returns are clear. . Ensure the well is loaded with seawater then freeze protect the well to 2200' with diesel. Bleed off all pressure, set a BPV in the tubing hanger and test to 1000 psi against BPV and cement. Secure well. Remove the well house and towlines. If necessary, level the pad and dig out the cellar. Please provide total well preparation cost on the handover form.
