I. Supervisor FROM:Guy Cook SUBJECT:Surface Abandonment Petroleum Inspector PBU 13-36 Hilcorp Alaska LLC PTD 1951670; Sundry 322-162 11/11/2022: Traveled out to location and met with Robert Bryan (Hilcorp) to witness cement to surface, confirm cut-off depth, confirm the information on the marker plate was correct, and witness the installation of the marker plate. After measuring from the top of the pad down to the cut off casing and getting the information about pad depth and tundra depth from Mr. Bryan, I concluded that the casing was cut approximately eight inches high. Mr. Bryan agreed they needed to cut the casing again to get it at least 3 feet under original tundra level. I left location after informing Mr. Bryan to let us know when he is ready for us to witness. 11/13/2022: I returned to PBU 13-36 and again met with Mr. Robert Bryan to witness the well’s surface abandonment. This time the casing had been cut deep enough to be 3 feet 5 inches below tundra level. The identification plate was installed, and all the proper information was confirmed to be on the plate. I informed Mr. Bryan that the well could be buried prior to leaving location.

Calculated leak rate for the ~7 hrs of logging began at 1.3 gpm and reduced to 0.15 gpm for an average of 0.19 gpm @2500 psi. The initial station log above the cement top (Eline correlated tag 3x @ 9217’ MD) was executed for an hour at the highest leak rate and showed no leak signature. A full pass was logged with the leak active across the entirety of the well including stop counts across the patch and previous cretaceous leak depth. No leak signatures were found. On 9/12/22, two MIT-T’s were conducted to 2750 psi max applied pressure and extended to one hour to better understand the pressure fall off. In the first hour test the pressure loss for the 15 minute intervals were: -322 psi, -109 psi, -64 psi, -38 psi. In the second hour test the pressure loss for the 15 minute intervals were: -95 psi, -39 psi, -36 psi, -33 psi. Test passed in the first 30 min of the 2nd hr test. Similar to the LDL leak rate, during the MIT’s the leak path is loading up and progressively reducing the LLR as more fluid is pumped, stabilizing at an extremely low leak rate. During the initial station log above the cement top at 9217’ MD, the acoustic and temperature signals would have been the most prominent due to the LLR being the highest if a leak were present. Based on this information it is unlikely that the cement top is leaking. In contrast, by the time logging was executed across the patch and cretaceous leak the LLR was extremely low which may have made the leak undetectable. I have attached the digital MIT-T data for you to review if you like. While this isn’t an ideal situation I think we have good evidence that the tubing cement top is not leaking based on the LDL. Let me know what you think and if you approve moving forward with the surface cement part of the procedure or want to discuss it more on Thursday.

Due to the low leak rate (0.7 gpm) we would propose to run an acoustic LDL. Logging program would look like this: 1. Baseline temp pass from surface to cement top with the well in static state. 2. Station log at the cement top while pumping (2600-2400 psi) on the tubing for ~1 hr, monitoring for a temperature shift or acoustic signal increase that would indicate flow past the plug. 3. Once station log is complete, log to surface while continuing to pump on the tubing. 4. Station log across patch/ cretaceous leak depth and over any other anomalies. This should give us good confirmation of where we are losing fluid to.

According to the Cerberus modeling we can put ~3600 pounds of downforce on the cement plug at 9285’ MD with 1-3/4” coil. Surface downforce with the injector can’t transfer any more weight downhole due the coil going helical in the tubing. Do you consider 3600 pounds to be “sufficient weight” in compliance with the plug confirmation requirements in 25.112(g)(1)?

In general remedial cement tops come in high on the tubing side and a 500’ high tag is not uncommon. The reason for this is believed to be caused by internal corrosion of the tubing increasing the actual volume per foot compared to the calculated tubing ID used for cement displacement volumes. On 13-36, the L-80 tubing is 27 years old and a caliper in 2010 showed maximum wall penetrations of 32%. These differences in the actual vs mill spec volumes are not taken into account for displacement of the cement due to the inaccuracy in attempting to calculate the change in volume hence the cement top on the tubing come in shallow. To compensate for this we pump excess cement to ensure we have the needed coverage. How would you like to proceed based on the two options proposed by Ryan in the previous email?

Here is where we are at: 1. We pumped 350 bbls of cement getting cement returns to surface in the IA, the IA is now cemented. Tubing is loaded w/ 9.8 brine. 2. SL tagged top of cement in the tubing @ 9252’ MD (AOGCC witnessed). 3. The MIT-T failed, starting pressure of 2750, lost 470 psi in 30 minutes. 0.7 gpm LLR. We propose 1 of the 2 options below. Option 1: Move forward with the surface cement plug, cementing tubing and OA from the surface casing shoe to surface. Option 2: 1. Eline set CIBP @ ~3600’ MD. 2. Dump bail 25’ of cement on the CIBP. 3. Slickline tag TOC (AOGCC witnessed). 4. MIT-T to 2239 psi passing pressure, 2500 psi max applied pressure (8956’ TVD depth of the 7 5/8” casing shoe x 0.25) 5. Move forward with the surface cement job as planned. Attached is the approved sundry. Please let me know your thoughts on proceeding.

The well has a cemented annulus has a cement plug installed at 9,285’ MD. A patch is installed from 5,454’ to 5,485’ MD. MIT-T failed to 0.7 gpm at 2,500 psi. A suspected cretaceous leak was reported in the PC at 5,450’ MD. A LeakPoint survey was run to determine the location of the leak causing the failing MIT-T. This would entail checking the cement plug, patch and remainder of the interval for leaks. x After tagging up on the cement plug, the tool string was placed near the top of cement. A leak was activated by pressuring the tubing to 2,600 psi and taking returns to the cemented annulus/formation. A one hour station reading was taken at depth followed by stations moving away from the plug. Section 4.2 shows the results of this portion of the logging operation. The acoustic tools showed base line readings indicating no leak was present in this area. The temperature measurements remained steady during this time period indicating no liquid movement deeper in the well. x To keep the leak active, it was planned to keep the tubing between 2,400 and 2,600 psi. Referring to the pressure measurements in Section 4.2, it was noted that elapsed time between pressure cycles went from 2.6 minutes to 23.3 minutes, approximately. Based on pressure loss over time in fixed volume, this equates to a 1.3 gpm rate reducing to 0.15 gpm. The average rate reported from the field was 0.19 psi. x Under the above conditions, a 30 fpm pass was taken from the plug to surface. Station readings were taken across the patch and across the suspected cretaceous leak area. The dynamic logging pass indicated no leaks. The station readings across the patch and cretaceous area yielded base line results also showing no signs of leak activity (Section 4.3). x The lack of discernable signal is likely due to the volume behind the leak loading up due to the cemented annulus restricting the flow path. It is typical to maximize rate and differential when executing a LeakPoint survey. In this case with the casing expanding a bit when pressured, this may produce diminishing returns under higher pressure. If further logging is required, it might be useful to test bleed off rate under lower pressures to attempt to increase the rate. x Utilizing an S300 (FlowPoint) sensor in stationary logging mode should be considered as well as an alternative. x Full API prints to be provided by Read Cased Hole.

He wanted to tag the plug first. Wireline was rigged up and started in the hole. John said that they had pumped 360 BBLs of 14 ppg class G cement. Wireline hit bottom at 9285 ft MD. I had them hit down on it a few times. Wireline was pulled out of the hole and the bailer was checked. It was full of soft cement (felt like putty) with a diesel smell. A 2500 psi MIT-T was peformed - lost 135 psi in the first 15 min and 102 psi in the second 15 min. I ask John if he wanted to hold it for 45 min. He said no as they tried a pretest on it and it keeps losing 100 psi every 15 min. He said that they need to regroup.

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.

Latest H2S value 140 ppm, nearby well 13 -08A, 2/28/11. WBS Safety Note: 125 ppm when on MI. Reference Log: PDS LDL, 12/3/11 Objective The objective of this program is to verify tubing secure for upcoming 13 -15A Drill -by, patch the tubing leak at 5463' MD and to bring the well back on Injection. Well History Well 13 -36 was originally drilled and completed as a horizontal Z4 pre - produced injector in 12/95. The well was initially put in production and 200' of perforations were shot in 4/00. In 11/00 the well was converted into an injector. Since conversion to injection, 13 -36 has received 14.4 BCF of MI in four slugs. The well was on PW injection when an IA pressure rise was noted on 9/15/10 and then an MIT- IA failed on 9/22/10 with a liquid leak rate of 8.1 gpm at 2500 psi. ALIT -TxIA to 2500 psi also failed on 11/6/11. Leak Detection Log's (LDL's) ran in October 2010 suggest that there are leaks at 5463' MD and 5483' MD, along with possible leaks at GLM's # 3 & # 4 and a temperature anomaly at 4508' MD without an acoustic signature. We dummied off the GLV's and ran another TecWell LDL in December 2011 which shows the GLV's are no longer leaking, no temperature anomaly at 4508' MD, and suggested that the WRP was leaking. Page 1 of 7 The leaking WRP was pulled iecember 2011. An IBP was set abovee perforations and a new CMIT-TxIA to 2500 psi passed after being monitored for 2 hours, giving confidence that there is integrity of the production casing. The 7- 5/8 "x4 -1/2" TIW HBBP -T Packer (Figure 1) has a port below the sealing element. It is suspected that this port is_ leaking_causin_gthe response_on_the and the failing CMIT- TxIA's with a tubing tail plug in the hole. The attached 3 -D view (Figure 3) from 2010 Caliper of leaking section shows pipe to be in good shape for setting of the patch. New sidetrack well 13 -27B is a horizontal producer that lies between injectors 13 -35 and 13 -36 that has fallen from - 4000 bopd initial rates in late September 2011 to - 600 bopd in January 2012. It is in need of pressure support from this injector. This program is designed to set a patch over the tubing leak at 5463' MD and potential leak at 5483' MD, and then test the integrity of the Inner Annulus to 2500 psi. cc: Well File For questions, comments, or concerns please call Garry Catron @ 564 -4424 (work) or 907 - 227 -7349 (cell). 13 -36 Patch Procedure Reference Log: PDS LDL, 12/3/11 Patch Specifications • 4-1/2" Single Set Baker KB, 30' Length • Alt components to be L -80 carbon steel • 2.37" minimum ID Depth Information • Setting depth: 5455' — 5485' MD • Patch Length: 30' element to element • Leak Location: TecWell identified a leak at 5463' MD and a potential leak at 5483' MD, referenced to WBS Revision Date 26- Oct -2003 • Tie -In log: PDS LDL, 20- Oct -2010 Jewelry Tubing 12/03/10 LDL Talley SSSV Nipple 2226 2215 GLM # 1 3536 3526 Top Packer 5455 Tubing Leak 5463 Potential Tubing Leak 5483 Bottom Packer 5485 GLM # 2 7542 7536 4 -1/2" XN Nipple 12209 / Patch (MD) 5455 -5485 Pre -job Notes: Page 2 of 7 • • , Ensure that patch•semblies are capable of running 2 -1/8" OD deflated IBP through them prior to running them in hole. 1.

The last AOGCC MITIA passed on 7/16/04. A MITIA was not conducted due to the well being shut-in for the FS3 facility shut-down. The well has now been reclassified as Under Evaluation so that the well may be placed on injection and an AOGCC witnessed MITIA may be obtained. An AOGCC witnessed MITIA is scheduled for July 27, 2008. The plan forward for the well is as follows: 1. Fullbore: AOGCC witnessed MITIA to 4000 psi while on water injection for UIC Regulatory Compliance. A TIO plot and wellbore schematic have been included for reference. Please call with any questions.

Eliot; NSU, ADW Well Integrity Engineer; NSU, ADW Well Operations Supervisor Subject: NOT OPERABLE: 13-36 (PTD #1951670) Due for AOGCC MITIA compliance All, Well 13-36 (PTD #1951670) is due to its AOGCC MITIA for regulatory compliance. Given the facility shut-down, we are unable to complete this test by the due date. Therefore the well is being reclassified as Not Operable. We'll proceed with setting a TTP and conducting the test. After that we'll reclassify the well as Operable for regular injection. Please let me know if you have any questions. Thank you, Anna From: Townsend, S. Eliot Sent: Friday, July 11, 2008 1:46 PM To: NSU, ADW Well Integrity Engineer Subject: 13-36 Anna, Well 13-36 is a WAG injector currently classified as Operable. The well is due for its 4 year compliance test on 07/16/08. Due to the flow station 3 shut down, the well cannot receive water so that it can be properly pressure tested to 4000 psi while online. A plan has been submitted to the WBL to load the well, set a plug, and then perform an AOGCC MITIA to 4000 psi holding 1500 psi on the TBG. Per our converstion earlier today, the AOGCC has agreed to allow this test to satisfy the 4 year regulatory compliance test requirement. Until this work can be completed, the WI Status of this well should be changed to Not Operable to prevent out of compliance injection. Thanks, S. Eliot Townsend alt.

BOX 100360 ANCHORAGE, ALASKA 99510-0360 DS 13-36 Conversion to WAG Injector The conversion of 13-36 from a Iow volume peripheral producer to a WAG injector, will provide support to periphery horizontal wells 13-27A and 13-08A, as well as vertical producer 12-36. All three of these wells are currently on-line and in need of pressure support. Reserve benefits will be realized from improved sweep efficiency and the injection of MI into this new pattern. This conversion requires minimal wellwork and surface facility modifications. Well 13-36 is a horizontal peripheral producer that was originally drilled and completed as a pre- produced injector in 1995. The well initially produced almost 6000 BOPD. After a year, total fluid production had fallen to less than 1000 BFPD. The well has not been hydraulically fractured. It produces through 415' of perforations in the cemented 5-1/5 liner. The well has produced approximately 750 MBO and 400 MBW. The reservoir pressure in this area is estimated to be approximately 3,350 psi. A static bottomhole pressure was obtained in the subject well last August. The measured pressure was 3,333 psi. Wellwork for this conversion includes pulling the existing gas lift valves and replacing them with dummies. Annular communication work will confirm the integrity of the casing and tubing strings. The facility work necessary to convert 13-36 to water injection service involves: cutting and capping the existing production line to the production manifold building, connecting jumper water and MI injection lines from the 13-06A injection lines, equipping the new water injection slot with a choke, check and drain valves. The existing production and gas lift facilities will be disconnected and abandoned in place. The well will be connected to water and MI service by "twinning" with 13-06A. Only one well can be on MI service at a time for the flow meter and choke valve to work properly. Installation of power to the well house heater and lights will also be required.

Commission Anchorage On October 28, 1998 you requested an update from Shared Service Drilling regarding Annular DispOsal Records from July 25, 1995 through present time. We compared your list with our records and are able to provide you with the following data: · Individual Annular Disposal Logs from the SSD database which coincide with the approved. wells on your attached AOGCC Annular Log. The.SSD records are proVided to you in the same order as listed on your log. · There were some wells on your list which were not injected into. These wells are identified as follows: ·Endicott wells 1.-03/P-16, 1,65/N-25, 1-59/0-24 EXploration well Pete's Wicked #1 · Milne Point wells E-22, E-23, F-O1, L-16, J-19, L-25, F-30, L-21, K-38, NMP #1 & #2, K-05, K-02, H-07, K-25, K-37, E-17, F-21, K-30, K-34, K,21i, F-66, K-06, K-54, K-33, F-49i, K-18 · PBU Wells E-38, 18-34, 15,42, 'S-29A, 15-46, B-36, 15-43, 11-38 · The reason many of these annuli were not used is because the waste materials generated from these wells were injected into other approved annuli. Hopefully the injection logs submitted with this letter will clarify this. In addition, please note that our records show: · The wells listed above in italics were permitted but not used for annular disposal. · The wells listed above in BOLD were not Permitted for annular disposal. Wells drilled after June 6, 1996 were required by SSD procedure to be permitted with a Sundry Approval (10-403) form. Our records show that no Sundry Approval for Annular Disposal was filed for these wells. Wells drilled between July 25, 1995 and June 6, 1996 were automatically approved for annular disposal with the Permit to Drill. · We also provide you with a cumulative report from our database of records from July 25, 1995 through the present. From those records, we show the following wells not listed on your report were used for annular dispOsal: SCANNED NOV 1 ~ 200~ ,Annular Disposal Letter 12/14/98 · Endicott wells i-23/O-15, 1-61/Q-20, 2-40/S-22 Exploration well Sourdough #3 - ~' ° o ~5 4 , ~ Mflne Point wells F-06, H-05, ~-06, J-13, L-24 - ~s-~ ~.,, PBU wells-18-30, 18-31, 14~,~-43, ~-34, E-36, G-~A, =d S-33' ~z'~ Individu~ logs ~e provided to ~ou for these ~ogs as we~l. · Finally, our records show that the B-24 outer annulus was left open (see attached correspondence) Thank you for the opportunity to provide clarity to these records.

As discussed this morning we propose 'setting three plugs in this well as detailed in the attached form. This will allow us to retain the wellbore for potential future sidetrack or service well use. We would like to keep the well's 9-5/8" x 7" annulus available for the injection of liquid 'wastes. There are no other well annulii on this pad for injection. The annulus for MPB-24 was approved for injection as part of the permit dated 25 January 1996. The annulus will be freeze protected before moving the rig. Thank you for your help in this matter.

The blowout prevention equipment (BOPE) must be tested in accordance with 20 AAC 25.035; and the mechanical integrity (MI) of injection wells must be demonstrated under 20 AAC 25.412 and 25.030(g)(3). Sufficient notice (approximately 24 hours) of the MI test before operation, and of the BOPE test performed before ddlling below the surface casing shoe, must be given so that a representative of the Commission may witness the tests. Notice may be given by contacting the Commission's petroleum field inspector on the North Slope pager at 659-3607.

Commission Anchorage Disposal Cuttings Handling: Cuttings should be hauled to the ball mill at CC-2A. Fluid Handling: All drilling and completion fluids can be annular injected. Request to have well DS 13-36 for annular pumping. Request to AOGCC for Annular Pumping Approval for DS 13-36: 1. Approval is requested for Annular Pumping into the DS 13-36 10-3/4" x 7-5/8" casing annulus. 2. As referenced in Area Injection Order #4, there are no drinking water aquifers in the Prudhoe Bay Field Eastern Operating Area (including the Lisburne Oil Pool), as the average level of Total Dissolved Solids (TDS) at the ambient water within the proposed project area is above 10,000 ppm. There are no domestic or industrial use water wells located within one mile of the project area. 3. The 10-3/4" casing shoe will be set at 3443' MD (3274' TVD) which is below the Permafrost and in shale formations in the Sagavanirtok above the Ugnu Formation. 4. The burst rating (80%) for the 10-3/4" 45.5# NT-80 casing is 4170 psig while the collapse rating (80%) of the 7-5/8" 29.7# USS-95 casing is 5760 psig. The break down pressure of the Ugnu formation is 13.5 ppg equivalent mud weight. The Maximum Allowable Surface Pressure while annular pumping is calculated according to the following equation and is 2790 psi for a 10.0 ppg fluid in this well (Assumes worst case in which 7-5/8" casing is filled with gas). MASP = 4170 psig - ((fluid density ppg - 1.9) X 0.052 X 10-3/4" Casing Shoe TVD) 5. A determination has been made that the pumping operation will not endanger the integrity of the well being drilled by the submission of data to AOGCC on 7/24/95 which demonstrates the confining layers, porosity, and permeability of the injection zone. 6. The cement design for this well ensures that annular pumping into hydrocarbon zones will not occur.
