Post Office Box 244027 Anchorage, AK 99524-4027 3800 Centerpoint Drive Suite 1400 Anchorage, AK 99503 Phone: (907) 564-4891 02/09/2024 Mr. Mel Rixse Alaska Oil and Gas Conservation Commission 333 West 7th Avenue, Suite 100 Anchorage, Alaska 99501 Re: Prudhoe Bay Surface Casing by Conductor Annulus Top-offs of Cement, Corrosion Inhibitor through 02/09/2024. Dear Mr. Rixse, Enclosed please find a copy of a spreadsheet with a list of Prudhoe Bay wells that were topped-off with cement, corrosion inhibitor in the surface casing by conductor annulus through 02/09/2024. Cement top-offs are executed as needed to mitigate the void space left at surface by minor cement fallback during the primary surface casing by conductor cement job. The remaining void space between the top of the cement and the top of the conductor is filled with a heavier than water corrosion inhibitor to reduce the risk of external surface casing corrosion. The attached spreadsheets include the well names, API and PTD numbers, treatment dates and volumes. 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 have any additional questions, please contact me at 564-4891 or oliver.sternicki@hilcorp.com.

Currently, there are C2 perfs near the heel of the well and C4 perforations at the toe. There are C4 and C2 sands present in the V-122 heel that have not yet been perforated; this frac program intends to perforate and hydraulically fracture 30' of the C4 and C2 sands in the heel. V-122 is well supported by injector V-121 i; the interaction between the two wells is seen during MI slugs in V-121 i. V-122 has permanent downhole pressure and temperature gauges.

Specific info such as amount of proppant left in tubing and estimated sand top will not be known until after the job is pumped. • The objective of this procedure is to get the well cleaned to facilitate post frac well test. • Recommend reviewing PE Manual section for Coiled Tubing Fill Cleanouts for specifics on reversing rates, speeds and CT loading. Planned Procedure 1. MIRU CT 2. MU BHA. 3. RIH down to estimated sand top and begin cleaning out with slick 1% KCL. 4. Continue down to10,219 CTMD. At this point we are 100' above the top perforation. Ensure CT is clean as it is expected that returns will begin to fall off as the nozzle nears the perforations. If returns begin to fall off, reducing BHP by lowering rate may keep returns at a manageable level. 5. Slowly continue to clean out until returns fall off to -80%. If returns are still good even after the nozzle is past the perforations (not likely but possible), continue to clean out to the IBP at 10,420' a. If SL was able to set GL design, use GL assist. 6. Continue to pull IBP. 7. FP to 2500'. 8. Pump a gel pill at surface out to the tanks to ensure CT is clean if necessary. 9. RDMO. Page 15 of 10 • S Appendix B -Test Separator Additional Flowback Procedure 1. MIRU ASRC. RU equipment to in a manner that allows CT to RU if an additional FCO is necessary. 2. POP the well to ASRC at minimum choke. Flow the initial returns to the flowline as long as the shake-outs meet the returned fluid/solids management guidelines. 3. Limit flow to 500 bpd 4. If solids are < 1%, increase the production rate to 1000 BLPD. 5. Flow bottoms up and sample for solids production. If solids are still below 1%, allow well to flow to 1500 BLPD. Flow bottoms up and sample for solids production. If solids are still below 1% continue to increase the flow rate in 500 BPD increments. The objective is to achieve maximum drawdown. Watch returns and do not continue to open choke if solids > 1%; allow well clean up before choke is opened further. 6. Once at FOC, stabilize the well for 4 hrs. Obtain a 3 hr purge, 8 hr welltest.

Page I 10 of 10 • • Date: July 2, 2015 Subject: V-122 Fracture Stimulation From: David Wages Engineer, BP Alaska o: 907.564.5669 c: 713.380.9836 To: Chris Wallace Attached is BP's proposal and supporting documents to fracture stimulate the Kuparuk interval of well V-122. V-122 is a horizontal, Kuparuk producer completed in 2007 with a cemented and perforated completion. Currently, there are C2 perfs near the heel of the well and C4 perforations at the toe. There are C4 and C2 sands present in the V-122 heel that have not yet been perforated; this frac program intends to perforate and hydraulically fracture 30' of the C4 and C2 sands in the heel. We are requesting a variance to sections 20 AAC 25.283, a, 3-4 which require identification of fresh water aquifers and a plan for basewater sampling. Please direct questions or comments to David Wages • • Affidavit of Notification (20 AAC 25.283,a, 1) Partners notified 6/11/2015: • ConocoPhillips ExxonMobil Chevron Department of Natural Resources Plat Identifying Wells(20 AAC 25.283,a,2,A-C) and Faults(20 AAC 25.283,a, 11) .. iit 3 - - - - .. .� S 5:mi;1 h. w Wells within '/z t. . w:..DT1Rt k > 100'throw mi. radius • V-106a V-121 • . © : V-115L2 50'-100`thrown C1TS I'` ° N.,- `r;.,''', 1 ...., .,.. \ <50 throw ,.

Per the plat above, there are no water wells within 'h mile of the subject well. f The above map shows 3 faults of concern, 1, 2, and 3. Fault number 1 is parallel to the primary fracture plane and should avoid any fracturing chemicals whereas faults 2 and 3 are far enough away so as to avoid contact with fracturing chemicals. As always, if a pressure indication is observed that indicates we've intersected one of the faults, fracturing operations will be shut down. Exemption for Freshwater Aquifers(20 AAC 25.283,a,3-4) Well V-122 is in the West Operating Area of Prudhoe Bay. Per Aquifer Exemption Order No. 1 dated July 11, 1986 where Standard Alaska Production Company requested the Alaska Oil and Gas Conservation Commission to issue an order exempting those portions of all aquifers lying directly below the Western Operating Area and K Pad Area of the Prudhoe Bay Unit for Class II Injection activities. Findings 1-4 state: • • 1. Those portions of freshwater aquifers occurring beneath the Western Operating and K pad areas of the Prudhoe Bay Unit do not currently serve as a source of drinking water. 2. Those portions of freshwater aquifers occurring beneath the Western Operating and K pad areas of the Prudhoe Bay Unit are situated at a depth and location the makes recovery of water for drinking water purposes economically impracticable. 3. Those portions of freshwater aquifers occurring beneath the Western Operating and K pad areas of the Prudhoe Bay Unit are reported to have a total dissolved solids content of 7000 mg/I or more. 4. By letter of July 1, 1986, EPA-Region 10 advises that the aquifers occurring beneath the Western Operating and K pad areas of the Prudhoe Bay Unit qualify for exemption. It is considered to be a minor exemption and a non-substantial program revision not requiring notice in the Federal Registrar. Per the above findings, "Those portions of freshwater aquifers lying directly below the Western Operating and K Pad Areas of the Prudhoe Bay Unit qualify as exempt freshwater aquifers under 20 AC 25.440." thus allowing BP exemption from 20 AAC 25.283, a, 3-4 which require identification of freshwater aquifers and establishing a plan for basewater sampling. Detailed Casing and Cement Information (20 AAC 25.283,a,5-6) Well V-122 was spudded on 12/5/2006 A 12-1/4" hole was drilled to 3649' where 9-5/8" 40#, L-80, BTC casing was run and cemented in place with 494 bbls of ArticSet lite lead and 36.7 bbls of 15.7 ppg Class G cmt with good returns to surface. After the plug was dropped, the casing was tested to 3500 psi for 30 min for a good test. A LOT to 12.0 ppg was performed after the shoe was drilled. A 8-3/4" intermediate hole was drilled to 10,685'. Once past casing set point, 7" 26# BTC-M casing was run and cemented in place with 179.6 bbls of LiteCrete cmt and 33.7 bbls of 15.8 ppg Class G. Casing was tested to 3500 psi for a passing MIT. After milling a window from 10,311'-1-,323' a 11.57 ppg EMW FIT was successfully achieved. A 6-1/8" hole was drilled to TD of 14,437'. 4-1/2" 12,6# L-80 IBT-M solid liner was run to 14,435' and cemented in place. The liner was performed in 13 intervals from 10,710' to 14,335'with 2-7/8" guns at 6 SPF. The completion assembly consisting of 3-1/2" and 4-1/2" tubing was run to 10,153' with the packer at 10,085' • .

Each individual frac pump has an electronic kickout that will kick the pumps into neutral as soon as the set pressure is reached. Since there are multiple pumps, these set pressures are set between 90% and 95% of the maximum allowable treating pressure.

Finally, there is a manual kickout that is controlled from the frac van. All three of these shutdown systems will be individually tested prior to high pressure pumping operations.

The corrosion inhibitor is engineered to prevent water from entering the annular space and causing e~ernal 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.

Gas Hydrates are expected at V-Pad near the base of the permafrost. Setting casing through the SV1 should keep hydrate exposure from extending past the surface hole. Recommended practices for drilling hydrates should be followed in the surface hole. Occasionally hydrates are encountered below the SV1. III. Lost Circulation /Breathing: A. Lost circulation risk is considered low in the horiz. section and low to mod. in the up hole intervals. IV. Kick Tolerance /Integrity Testing: A. The 9 5/s" casing will be cemented to surface. The 7" casing will be cemented to 1000' MD from the surface casing shoe.

A heightened awareness of kick detection, pre-job planning and trip tank calibration will be essential while drilling/tripping the intermediate/production intervals. V. Stuck Pipe A. There could be differential sticking across the Schrader Bluff while running the 7" casing. Keep the casing moving as much as possible and follow the centralizer program to help with standoff. VI. Hydrogen Sulfide A. V-Pad is not designated as an HZS site, however Standard Operating Procedures for HZS precautions should be followed at all times. No measurable HZS is being produced from the formation at this time. However 10 ppm is measured regularly at V-Pad as a result of the use of Ivishak gas lift gas. All V-Pad gas lift wells will likely have HZS in this concentration. Note that all injection has been with produced water not seawater.

Re uest The AOGCC is in the process of developing a guideline document clarifing the intent of the regulations pertaining to function pressure testing ram type BOP's. BPXA requests a variance to the provisions of 20 AAC 25.035 (e}(10)C regarding the function pressure test requirement after the use of BOP ram type equipment for other than well control or equivalent purposes, except when the routine use of BOP ram type equipment may have compromised their effectiveness. (Example would be when pipe rams are inadverten#ly closed on a tool joint during routine operations.} The activities associated with this request will not compromise the integrity of the BOP equipment. Background AOGCC regulations require rams that have been used in the course of primary drilling & completion, workover and through tubing drilling operations be function pressure tested before the next wellbore entry. This is not a new regulation. The intent of this regulation is to ensure that ram type equipment has integrity after it has been utilized in a wellbore...for example; to ensure integrity if a ram was closed on a tool joint. The exact regulation language is: "if BOP sealing ram type equipment has been used, it must be function pressure-tested, before the next welibore entry, to the required working pressure specified in the approved Permit to Drill, using anon-compressible fluid, except that an annular type preventer need not be tested to more than 50 percent of its rated working pressure;" The pertinent sections are: 20 AAC 25.035 (e}{f 0)C PRIMARY DRILLING AND COMPLETION; 20 AAC 25.036 (d){4} THROUGH TUBING DRILLING AND COMPLETION; 20 AAC 25.285 (f)(2) TUBING WORKOVERS: 20 AAC 25.286(e}(1} WORKSTRING SERVICE OPERATIONS This issue has been discussed with Winton Auber# at the AOGCC. The test requirement in the regulation is intended to apply to ram type equipment only. The AOGCC understands that ram type BOP's are utilized for purposes other than well contro! in the normal coarse of operations. The regulations allowing a variance are at 20 AAC 25.035(h} PRIMARY DRILLING AND COMPLETION; 20 AAC 25.036(() THROUGH TUBING DRILLING AND COMPLETION; 20 AAC 25.285(h) TUBING WORKOVERS; 20 AAC 25.286(g) WORKSTRING SERVICE OPERATIONS...which says generally: 20 AAC 25.035(h)... Upon request of the operator, the commission will, in its discretion, approve a variance (1) from the BOPE requirements in (e) of this section if the variance provides at least an equally effective means of well contro(; by V-122P61 (P5) Proposal Schlumberger Report Date: October 25, 2006 Survey 1 DLS Computation Method: Minimum Curvature / Lubinski Client: BP Exploration Alaska Vertical Section Azimuth: 63.895° Field: Prudhoe Bay Unit - WOA /, Vertical Section Origin: y N 0.000 ft, E 0.000 ft Structure 1 Slot: V-Pad /Plan V-122 (S-U) I ~~ s uM TVD Reference Datum: Rotary Table Well: ~~ Plan V-122 (S-U) S~ TVD Reference Elevation: 82.40 ft relative to MSL Borehole: Plan V-122P61 ~e~ Sea Bed 1 Ground Level Elevation: 53.90 ft relatlve to MSL UWIIAPI#: 500292332870 Magnetic Declination: 23.855° Survey Name!

There could be differential sticking across the Schrader Bluff while running the 7" casing. Keep the casing moving as much as possible and follow the centralizer program to help with standoff. VI. Hydrogen Sulfide i A. V-Pad is n`ot ~ignated as an HZS site, however Standard Operating Procedures for HZS precautions should bellowed at all times. No measurable HZS is being produced from the formation at this time. However 10 ppm is measured regularly at V-Pad as a result of the use of Ivishak gas lift gas. All V-Pad gas lift wells will likely have HZS in this concentration. Note that all injection has been with produced water not seawater. HZS levels are expected to remain low until the water flood matures.

Re uest The AOGCC is in the process of developing a guideline document clarifing the intent of the regulations pertaining to function pressure testing ram type BOP's. BPXA requests a variance #o the provisions of 20 AAC 25.035 (e)(10)C regarding the function pressure test requirement after the use of BOP ram type equipment for other than well control or equivalent purposes, except-when the routine use of BOP ram type equipment may have compromised their effectiveness. (Example would be when pipe rams are inadvertently closed on a tool joint during routine operations.) The activities associated with this request will not compromise the integrity of the BOP equipment. Background AOGCC regulations require rams that have been used in the course of primary drilling & completion, workover and through tubing drilling operations be function pressure tested before the next wellbore entry. This is not a new regulation. The intent of this regulation is to ensure that ram type equipment has integrity after it has been utilized in a wellbore...for example; to ensure integrity if a ram was closed on a tool joint. The exact regulation language is: "if BOP sealing ram type equipment has been used, it must be function pressure-tested, before the next wellbore entry, to the required working pressure specified in the approved Permit to Drill, using anon-compressible fluid, except that an annular type preventer need not be tested to more than 50 percent of its rated working pressure;" The pertinent sections are: 20 AAC 25.035 (e}(10}C PRIMARY DRILLING AND COMPLETION; 20 AAC 25.036 {d)(4} THROUGH TUBING DRILLING AND COMPLETION; 20 AAC 25.285 (f)(2) TUBING WORKOVERS: 20 AAC 25.286(e}(1) WORKSTRING SERVICE OPERATIONS This issue has been discussed with Winton Aubert at the AOGCC. The test requirement in the regulation is intended to apply to ram type equipment only. The AOGCC understands that ram #ype BOP's are utilized for purposes other than well control in the normal coarse of operations.
