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 Y-22A was suspended on 10/29/1988. 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 secured with the top of the cement plug at 7613’ in the 9-5/8” casing. The well is mechanically sound as proven by a pressure test of the cement top and casing to 3000psi on 10/28/1988. Based on these conditions and the inspection on 09/15/2019 Prudhoe Bay Unit well Y-22A 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 Y-22A 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 Y-22A (PTD #188115) Technical Justification for Renewal of Suspended Status May 26, 2020 Well History and Status Prudhoe Bay well Y-22A (PTD #188115) was suspended on 10/29/1988 after a failed sidetrack attempt. The parent wellbore was abandoned on 10/10/1988 from PBTD to 8083' MD prior to the rig sidetrack. A section was milled in the 9-5/8" casing from 7782' to 7842' MD. After setting a cement plug and kicking off, an 8-1/2" hole was drilled to 8210' MD. At this depth, the bit was pulled for a BHA change. The original hole was never found after changing out the BHA. An EZ Drill was set at 7718' MD, 64' above the top of the window. 64 cubic feet of cement was squeezed below the retainer leaving the calculated bottom of cement at 7882' (100' below the window) and 41 cubic feet of cement was left on top of the retainer. The cement was tagged at 7613' (105' above the cement retainer) and successfully pressure tested to 3000 psi on 10/28/1988. The well is mechanically sound as indicated by the pressure test after the cement plug was placed in the 9-5/8" casing. 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 well Y-22A 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 = -/0/350 psi. Request BPXA requests approval for renewal of the existing suspension status for Y-22A. 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.

Prudhoe Bay Oil Pool well Y-22A Technical Justification for Application for Renewal of Suspension Status August 18, 2010 Well Status Prudhoe Bay unit well Y-22 (PTD #1881150) was suspended on 10/29/1988 after a failed sidetrack attempt. The parent wellbore was abandoned on 10/10/1988 from PBTD to 8083' MD prior to the rig sidetrack. A section was milled in the 9-5/8" casing from 7782' to 7842' MD. After setting a cement plug and kicking off, an 8-1/2" hole was drilled to 8210' MD. At this depth, the bit was pulled for a BHA change. The original hole was never found after changing out the BHA. An EZ Drill was set at 7718' MD, 64' above the top of the window. 64 cubic feet of cement was squeezed below the retainer (leaving the calculated bottom of cement at 7882' (100' below the window) and 41 cubic feet of cement was left on top of the retainer. The cement was tagged at 7613' (105' above the cement retainer) and successfully pressure tested to 3000 psi on 10/28/88. The well is mechanically sound as indicated by the pressure test after the cement plug was placed in the 9-5/8" casing. 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 Y-22A 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/1/O = 0/0/80. During the inspection, it was discovered the well sign was missing. Anew sign will be ordered and placed on the well. Request BPXA requests approval for renewal of the existing suspension status for Y-22A. 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. STATE OF ALASKA ALASKA AND GAS CONSERVATION COMMISS~ REPORT OF SUNDRY WELL OPERATIONS 1.

Plans for well inspections are in place for October 1 through October 3, 1994 as discussed with Blair Wondzell and John Spaulding. Updated reporting has been filed with the commission as listed. Yours Sincerely, Steve Herren Drilling Manager Bill Bredar Patrick Collins Jim Farnsworth Mike Miller Bruce Policky Scott Sigurdson Marian Sloan RECEIVED 0CT 1 4 1994 Alaska 0il & Gas Cons. Commission ~chor~ Suspended Wells, Request to retain suspension status The following wells are listed as suspended by the AOGCC under 20 AAC 25.110. These wells are requested to remain suspended for the reason(s) as indicated. Site inspections should be conducted as soon as possible. MPA-01; 029-20376-00 79-,¢'04 Potential recompletion in the Kuparuk C and/or B sand as a water injector. Decision hinges on 1994/95 development drilling results (E-13)in this area. MPB-02; 029-20662-00 81-/¢'142 This well is scheduled for initial completion in the Schrader Bluff late this year or early next year. MPA-03; 029-20891-00 83-~001 Future utility as a Schrader Bluff producer with producing utility when sudace infrastructure is installed on A pad. MPN-01 B; 029-21053-02 84-0013 N-01 B is a usable well in the Schrader Bluff, with producing utility when surface infrastructure is installed on N pad. The well should be retained in a suspended status until that time. MPC-16; 029-21364-00 85-O 110 C-16 has recompletion potential in the Kuparuk "C" sand and/or the Schrader Bluff horizons. Although additional evaluation must be performed to quantify reserves and production potential, C-16 is believed to be a viable workover and/or sidetrack candidate. NWM#1; 029-22231-00 91-0145 Northwest Milne #1 should remain suspended until the Northwest Milne Point development is better defined. The wellbore is strategically located on a gravel island and may. possess utility in either production or injection operations. DNR recently certified this well as capable of production. No Point #1;029-22450-00 94-0027 No Point #1 will be utilized in the upcoming F- Pad development. Expectations are to complete the Kuparuk "A" zone and commence production 4Q95. Niakuk #4, 029-21217-00 84-0200 Niakuk #4 is requested to remain suspended until the viability of the well for monitoring is defined. Niakuk #5, 029-21290-00 85-0027 Niakuk #5 should remain suspended for observation purposes at this time. Sag Delta #33-12-16, 029-20176-00 75-0058 Area being drained by 1994 Alapah well NK-26 (HAW). Potential use as a monitor well for this new reservoir Would have to truck oil across winter ice road if resume production Produced 186 MBO in 1985 2 month production test. Sag Delta #5, 029-20527-00 80-0129 Area being drained by L5-26 (high gas well), L5-28, and L5-36 from south to west. Well tests indicated fairly tight, but productive rock; perhaps inadequate stimulation? Costs prohibitive for eventual tie-in to L5 (? via Heald Point). Potential for gas cap monitor well Sag Delta 31-11-16, 029-20011-00 69-0014 Area being drained by L4-36, 80 Acre offset to NW. Potential for service well (water injection?) Well is capable of production, but most Lisburne in water leg and costs likely prohibitive for tie-in to L4. Sag Delta #2A, 029-20234-01 77-0069 South of Sag Delta #1, in water leg of Alapah oil accumulation in NK-26 well. Remote potential for pressure monitoring of Alapah offtake and the effect on the Alapah aquifer; though, costs would likely be prohibitive.

This well may possess utility for production or as an observation well. Z-32 was shut in due to high water production in 1992. In 1993 it was sidetracked to a new location. The oil column at the new location was less than prognosed and was not considered economic and the well was suspended. There is oil in the area that can be reached as a new sidetrack from this well. A specific location has not yet been identified, but we wish to retain this wellbore for a future sidetrack. S-10 was sidetracked in 1992. Drilling difficulties were encountered while drilling through a fault in the Kingiak and the well was suspended. There is oil in the area that can be reached as a new sidetrack from this well. A specific location has not yet been identified, but we wish to retain this wellbore for a future sidetrack. The West Sak formation, a non unitized formation in the PBU license area, is reachable from this wellbore. Work in ongoing on a facility sharing agreement. In the case that a satisfactory agreement is reached, this weilbore could be used to access oil in this formation. Y-22A, 029-21558-01 88-0115 Y-22 was sidetracked in 1988. The sidetrack was suspended due to drilling difficulties. There is oil in the region that can be reached as a new sidetrack from this well. A location has not been worked on but we wish to retain this wellbore for a future sidetrack. U-01, 029-22244-00 92-00I 1 There is oil in the area that can be reached as a new sidetrack from this well. A specific location has not yet been identified, but we wish to retain this wellbore for a future sidetrack. PR 33-12-13, 029-20047-00 69-0104 The well penetrates The West Sak and Ugnu formations in the aquifer. Work in ongoing on a facility sharing agreement with subsequent appraisal of the formations. This well could be used to test the aquifer properties. These wells are listed as suspended, action items are detailed. Ak Island #1,289-20018-00 81-0119 Alaska Island #1 was abandoned in 1988. The completion notice has been refiled with AOGCC on 9/15/94. The site is ready for inspection (priority 1 ). Niakuk #lA, 029-20156-01 76-0028 Niakuk #lA was abandoned in 1991. A sundry application requesting status change was filed with AOGCC 9/20/94. A completion notice will follow when the sundry application is approved. The site is ready for inspection (priority 1). Niakuk #2A, 029-20180-01 76-0079 Niakuk #2A was abandoned in 1991. A sundry application requesting status change was filed with AOGCC 9/20/94. A completion notice will follow when the sundry application is approved. The site is ready for inspection (priority 1). PBU H-01, 029-20099-00 71-0015 The well was drilled in 1971 and hit a down thrown fault block with only 20ft of oil bearing Ivishak. This was not economic at the time. It was left suspended without tubing. Recent success in fraccing the Sag formation indicated that it might be an economic well. A rig workover was completed in April 1994 and the well was put on production 9/94. It is not necessary to inspect this site. Kemik Unit #1,223-20006-00 70-0060 Kemik Unit #1 is scheduled to be abandoned in the near future. Abandonment planning is now in progress. Site inspection will not be necessary at this time most likely should be scheduled for Spring of 1995. P2-59, 029-22096-00 90-0140 Arco Alaska Inc. is the operator of this well, they will be addressing the question of suspension.

In October 1988, Y-22 was re-entered and a section was milled from 7782' MD to 7842' MD. After setting a cement plug and kicking off, an 8 1/2" hole was drilled to 8228' MD (438' total hole). Once this depth was reached, the bit was pulled for a BHA change. The original hole was never found again after tripping back in the hole. Each attempt to find the old hole resulted in a sidetrack. The effort was finally abandoned. So the only hole made was from 7790' MD to 8228' MD. The survey information for that hole is listed above.

When I arrived on location, the tagging of the cement plug at 7613 had already been tagged~ and the 3000 psig test was completed with six stands of drill pipe out of the hole. i was late because Max Fernandez, company operator, said they wouldn't be ready until 9:00 p.m at the earliest. I arrived on location at 5:15 p.m. and they had just completed tag and pressure test. t informed Max, because he told me not to come earlier, that the Con, mission would want it done over. They obliged. I received schematics from Max. The tag and pressure test was satisfactory. In summary, I witnessed the tagging and pressure test on well Y-22A for SAPC which was satisfactory. 02-001A (Rev. 8/85) ,, y 7_/.

(The total volume of cement pumped for these 4 plugs was 756 Cult). However it was eventually decided that the hole conditions around the area of the window were so poor that it would be prudent to suspend the well. On 10-28-88 an EZ Drill was set at 7718' (see attached diagram), 64' above the top of the window. 64.1 Cuft of neat G cement was squeezed below the retainer (leaving the calculated bottom of cement at 7882' (100' below the bottom of the window), and 41 Cuft of neat G cement was dropped on top of the retainer. The cement was then tagged at 7613' (105' above the retainer) and pressure tested to 3000 psi (witnessed by Mr Harold Hawkins of the AOGCC). The top 500' of 9-5/8" casing was then freeze protected with diesel and a christmas tree installed on the well.

This new bottom-hole location (well) will be called Y-22A. Well Y-22A will be a horizontal drainhole with a proposed bottom-hole location close to the old Y-22 location. From the plan view, the new wellbore (Y-22A) will be displaced approximately 550 feet from the old wellbore (Y-22) and from the section view, the new wellbore will drop below and cross beside the old wellbore (see attached directional map). The closest well other than Y-22 is well Y-13 which is approximately 2000 feet to the South East of the proposed well Y-22A (see attached well locations/ structure map). Based on these facts, there will be no close approaches with other wellbores in the area. A maximum allowable distance will be maintained from the old wellbore of Y-22.
