John McMullen., BPXA Well Integrity and Interventions Manager Post Office Box 196612 Anchorage, Alaska 99519-6612 May 26, 2020 Mr. Jeremy Price Alaska Oil and Gas Conservation Commission 333 West 7th Avenue Anchorage, Alaska 99501 Subject: Prudhoe Bay Well H-10A (PTD #197190) Application for Renewal of Existing Suspension (10-403) Dear Mr. Price, BP Exploration (Alaska) Inc. completed an AOGCC witnessed suspended well inspection of Prudhoe Bay Unit well H-10A on 08/17/2019 (20 AAC 25.110 (h). This recently submitted suspended well inspection reflects the current condition of the well (reference 20 AAC 25.110 (f)) and supports the request for renewal of suspension. Recent events from this well indicate that this well is mechanically sound. Specific attachments include: x Wellbore diagram illustrating the current configuration of the well x Suspended Well Site Inspection form documenting the pressures and site condition Prudhoe Bay Unit well H-10A was suspended on 11/24/1997. It is located on a pad with active wells and/or service wells. The strata through which the well was drilled is neither abnormally geopressured or depleted. The well is mechanically sound and secured with the top of cement at 2293’ in the 9-5/8” casing. Based on these conditions and the inspection on 08/17/2019 Prudhoe Bay Unit well H-10A meets the provisions required in 20 AAC 25.110 (a)(1). BPXA requests approval for renewal of the existing suspension status for this well. Attached is an Application for Sundry Approval (10-403) with a technical justification summarizing the information on the current status and condition of the well (reference 20 AAC 25.110 (a), (b), (e), (h)). In summary, BPXA believes Prudhoe Bay well H-10A is mechanically sound and secure and meets the requirements for renewal of suspended status. If you have any questions, please call me at 529-9129 or Ryan Holt/ Andrew Ogg at 659-5102. Sincerely, John McMullen BPXA Well Integrity and Interventions Manager Attachments Technical Justification 2019 Suspended Well Site Inspection form Wellbore Schematic Prudhoe Bay Well H-10A (PTD #197190) Technical Justification for Renewal of Suspended Status May 26, 2020 Well History and Status Prudhoe Bay well H-10A was suspended 11/24/1997 after an unsuccessful sidetrack attempt. During sidetrack operations an attempt was made to fish stuck drill pipe and the BHA with a neutron source tool. A 10-403 sundry form was submitted to the AOGCC on 11/24/1997 documenting a fish left in the hole from 3727' to 10360' MD (drill pipe and neutron LWD tools) and steps taken to suspend operations. The well was secured with an EZSV retainer at 2429' and cement from TD of 10600' to 2293' MD. 4- 1/2" L80 tubing was left from 1003' to surface. The well is mechanically sound as indicated by the EZSV and the cement plug placed in the well and the successful pressure test. The well will not allow the migration of fluids, will not damage freshwater or producing or potentially producing formations, will not impair the recovery of oil or gas, is secure, safe, and not a threat to public health. The strata through which the well was drilled is neither abnormally geo-pressured or depleted. Condition of the Wellhead and Surface Location Prudhoe Bay Unit well H-10A is located on an active, well maintained pad with clean gravel. The pit and surrounding area are in good condition. There is no discoloration and no sheens on the pad, pits, or in nearby water. The well pressure readings are T/I/O = -/500/290 psi. Request BPXA requests approval for renewal of the existing suspension status for H-10A. A variance to the provisions of 20 AAC 25.110 (c) (2) is also requested under 20 AAC 25.112 (i) to allow the well to remain as suspended in its current condition. All hydrocarbon intervals are isolated and there are no underground sources of fresh water in this area.

AUG 2 Mr. Jim Regg � i � 012 ` Alaska Oil and Gas Conservation Commission 333 West 7 Avenue Anchorage, Alaska 99501 ! / Subject: Corrosion Inhibitor Treatments of GPB H -Pad 14- 1'941 41 Dear Mr. Regg, Enclosed please find multiple copies of a spreadsheet with a list of wells from GPB Pad H that were treated with corrosion inhibitor in the surface casing by conductor annulus. 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.

Form 10-403 Revised 1/2010 __ -_ ~ Submit in Duplicate )f1 Pru oe Bay Oil Pool well H-1OA~ Technical Justification for Application for Renewal of Suspension Status August 18, 2010 Well Status Prudhoe Bay well H-10A was suspended 11/24/1997 after an unsuccessful sidetrack attempt. During sidetrack operations an attempt was made to fish stuck drill pipe and the BHA with a neutron source tool. A 10-403 sundry form was submitted to the AOGCC on 11/24/97 documenting a fish left in the hole from 3727' to 10360' MD (drill pipe and neutron LWD tools) and steps taken to suspend operations. The well was secured with an EZSV retainer at 2429' and cement from TD of 10600' to 2293' MD. 4- 1/2" L-80 tubing was left from 1003' to surface. On 2/19/2010, the conductor was treated with 1.7 gallons for RG2401 for surface casing corrosion mitigation. The well is mechanically sound as indicated by the EZSV and the cement plug placed in the well and the successful pressure test. The well will not allow the migration of fluids, will not damage freshwater or producing or potentially producing formations, will not impair the recovery of oil or gas, is secure, safe, and not a threat to public health. The strata through which the well was drilled is neither abnormally geo-pressured or depleted. Condition of the Wellhead and Surface Location Prudhoe Bay Unit well H-10A is located on an active, well maintained pad with clean gravel. The pit and surrounding area are in good condition. There is no discoloration and no sheens on the pad, pits, or in nearby water. The well pressure readings are T/I/O = 0/0/0. Request BPXA requests approval for renewal of the existing suspension status for H-10A. A variance to the provisions of 20 AAC 25.110 (c) (2) is also requested under 20 AAG 25.112 (i) to allow the well to remain as suspended in its current condition. All hydrocarbon intervals are isolated and there are no underground sources of fresh water in this area.

As the attached AOGCC BOPE Test Report shows there was one failure. One valve downstream of the hyd. Choke had a very slow leak on the high pressure test. This valve was greased and retested OK. The testing went very well with good test procedures being employed by the Nabors crew. The rig was clean and all equipment seemed to be in good working order. The location was clean and all extra equipment was stored properly. Summary: I witnessed the weekly BOPE test on Nabors Rig 2ES drilling BPXs PBU H-10A well.

H-10 is a conventional big bore design, but with a 7" cemented liner tieback extending from the original liner top to 2500' MD. An aggressive three dimensional directional profile is necessary to intersect the target polygon. A 1300 foot high angle well- bore is planned to access the ivishak Zone 4B target, positioned using a pilot wellbore to determine structure and fluid levels. A high angle section will penetrate the Zone 4B interval at approximately 80°. P50 NLOC is 68 feet. The Sag River lateral sidetrack should be about 1900 feet in an area of nearly flat structural dip. This target is a safe fallback which should provide moderate production rates. P50 NLOC is 25 feet.

H-10 is a conventional big bore design, but with a 7' ce- mented liner tieback extending from the original liner top to 2500' MD. An aggressive three dimensional directional profile is necessary to intersect the target polygon. A 1300 foot high angle wellbore is planned to access the Ivishak Zone 4B target, positioned using a pilot wellbore to determine structure and fluid levels. A high angle section will penetrate the Zone 4B interval at approximately 80°. P50 NLOC is 68 feet. The Sag River lateral side- track should be about 1900 feet in an area of nearly flat structural dip. This target is a safe fallback which should provide moderate production rates. P50 NLOC is 25 feet.
