I. Supervisor FROM: Lou Grimaldi SUBJECT: Wellbore Plug Verification Petroleum Inspector PBU H-25 PTD 1852680, Sundry 316-089 - BPXA Tuesday, October 11, 2016: I witnessed the failed verification of isolation plug at the surface casing window in BPXA's well# H-25 in the Prudhoe Bay Unit. Guy Cook, AOGCC Petroleum Inspector, accompanied me on today's verification attempt. We arrived at the rig at the appointed time this morning to find the rig washing - down at approximately 7100 ft RKB with a BOP stack washing tool (Swizzle Stick). The top of the milled window in the 9 5/8-inch casing was at 7490 ft. There were no visual indications of clabbered cement although mud pH had increased from 10.3 to 11.6 which is normally a good indicator of mud contaminated with cement. The rig continued to wash down to 7480 ft (10 ft above window) without any visual signs - of cement. In discussion with Keith Conatser (BPX DSM) it was decided to get guidance from town. We left location at this time. Thursday, October 13, 2016: I returned this evening and witnessed a successful tag_ and pressure test of hard cement that had reportedly been placed on a retainer set in the casing. This procedure had been reported as approved verbally in town. The pressure test was performed first at 250 psi for 5 minutes then brought up to 1750 psi and fell to 1550 in the first 30 minutes. The pressure was brought back up to 1760 psi fell to 1678 in thirty minutes (non linear). Total fluid pumped was 3 bbl's and 2.9 bbl's were bled back. The rig then tagged cement with a 8 1/2" rotary cone bit while pumping at 2-3 bbl's per minute. The top of cement was found at 7105 ft RKB and 15K lbs was set down while pumping. There were no signs of making hole or sticking when picked up 10 ft and a - second tag was made in the same spot. I left location at this time.

Request: Approval is requested for the P&A of Prudhoe Bay well H-25 to sidetrack and complete H- 25A MIT-IA Passed to 3850 psi (11/20/2015) MIT-OA Passed to 1320 psi (11/20/2015) PPPOT-T Passed to 5000 psi (11/20/2015) PPPOT-IC Passed to 3500 psi (11/20/2015) PPPOT-OC Failed (11/24/2015) - see note below MIT-T See Note Below Well History: H-25 was originally completed in 1985 and the tubing was replaced in a 2003 rig workover. In 2014 an organoseal/squeezecrete gas shut off was attempted to shut off high GOR perfs, however the cement set up early and could not be milled out. Therefore, this well is no longer productive and has •-en re ease. • .• .- ra Organo-Seal/Squeeze Crete Job: 50 bbls of organoseal (a formation damaging gel)was pumped into the perfs and was followed by 30.2bbls of 14ppg"squeezecrete"cement which was laid into the liner after displacing the gel. While attempting to wash back down to bottom, hard cement was tagged at 9818'MD. Subsequent attempts to mill through the cement were not successful. While this cement plug was nthonginaTly intended to be the reservoir P&A plug, it does comply with 20 AAC 25.112.c.1.B well plugging requirements. Additionally, as part of the pre-rig work, it is planned to set a mechanical TTP in the X nipple below the packer. MIT-T: The cement in place (production liner)was tested to 2,755psi for 30 minutes on 1/28/2015. This test bled off 162psi the first 15 minutes and 80psi the second 15 minutes. It is proposed that a tubing tail plug be set at 9,514'MD and be pressure tested to 3,000psi. This tubing plug in conjunction with the pressure tested cement in the production liner will be the P&A kit for this wellbore. An �--- approved sundry will be considered approval of this P&A plan. PPPOT-OC: H-25 has a unique wellhead. During the original 1985 completion the surface casing was stuck high of the landing ring. Therefore a slip lock starting head was installed. This starting head contains a packoff with two seals. Currently the upper seal is holding per the MIT-OA but the secondary lower pack off seal fails a test. The well is currently operable. There will be attempts at plastic packing (or other methods)to fix this lower seal but it is not needed for well operability. MIT-OA: H-25 passes a pressure test to 1320psi however there has been histor roof communication between the IA and OA when the well is on gas lift. This well is not planned to have permanent gas lift, however in the likelihood of using gas lift, the integrity to gas is desired. Therefore this sundry will cover the pre-rig attempt at cementing the 13-3/8" surface casing x 9-5/8" intermediate casing. If this job cannot be completed pre-rig then a rig intervention will be necessary. This will be referred to as the contingency completion. "we �,/�,e/ r4 b- ' T CorCv�.

Pre-rig, the reservoir wilLbe considered abandoned with the current cement plug in the 7" production liner and a tubing tail plug set at 9,514'MD. A tubing cut will be made at the intended whipstock departure depth of approximately 7,500'MD. A tubing punch will be made through the tubing and 9-5/8" casing, the 13- 3/8" x 9-5/8" casing annulus will then be cemented to surface. The OA packoff will be filled with sealant.A TWC and dry hole tree will be set and in preparation for the rig to move to location. The rig will arrive on location and NU and test BOPs. The tubing will be pulled and laid down. A cleanout run will be performed to the proposed kickoff depth.A 9-5/8"whipstock will be run with a 8.5" milling assembly to mill the window for sidetrack. The 8.5" intermediate hole section will be drilled to the top of the Sag River formation and 7" casing will be run to surface. After the packoff is installed a second tubing spool will be added. The production hole will then be drilled to TD in Zone 3 of the Ivishak formation. The inverted U shape production hole will be targeting both Zone 3 and Zone 4 reserves. A 4-1/2" production liner will be cemented in place and 4-1/2" tubing will be run to the top of the production liner.

Those wells that are not re-drilled immediately are identified every 6 months and assigned a current status of"Suspended." Step Task Responsible 1 The initial reviewer will check to ensure that the "Plug for Redrill" box Geologist in the upper left corner of Form 10-403 is checked. If the "Abandon" or /. "Suspend" boxes are also checked, cross out that erroneous entry and V initial it on both copies of the Form 10-403 (AOGCC's and operator's copies). 2 If the "Abandon" box is checked in Box 15 (Well Status after proposed Geologist work)the initial reviewer will cross out that erroneous entry and initial then As- it on both copies of the Form 10-403 (AOGCC's and operator's copies). Instead, check the "Suspended"box and initial that change. Drilling Engineer The drilling engineers will serve as quality control for steps 1 and 2. (QC) 3 When the Stat Tech receives a Form 10-403 with a check in the "Plug Stat Tech for Redrill" box, she will enter the Typ_Work code "IPBRD" into the History tab for the well in RBDMS. This code automatically generates a comment in the well history that states "Intent: Plug for Redrill." 4 When the Stat Tech receives any Form 10-407, she will check the Stat Tech History tab in RBDMS for the "Intent: Plug for Redrill" code (IPBRD). If present and there is no evidence that a subsequent re-drill has been COMPLETED, the Stat Tech will assign a status of SUSPENDED to the well bore in RBDMS no matter what status is listed on the 10-407. The Stat Tech will also change the status on the 10-407 form to SUSPENDED, and date and initial this change. If the Stat Tech does not see the "Intent: Plug for Redrill" comment or code, she will enter the status listed on the Form 10-407 into RBDMS. 5 When the Form 10-407 for the redrill is received, the Stat Tech will Stat Tech change the original well's status from SUSPENDED to ABANDONED. 6 The first week of every January and July, the Stat Tech and one of the Stat Tech Geologists will check the "Well by Type Work Outstanding"user query in RBDMS to ensure that all of the Plug for Redrill wells have been Geologist handled properly. At this same time, they will also review the list of suspended wells for accuracy. kc65 Gyrodata Incorporated • • 5%5'' iata**3000 Northwest Lake Dr. gyfact ouston, Texas 7095 Precision wellbore Placement T: (281) 213-6300 • F: (281) 213-6301 R ECv I ED AOG CC sGANtiED JUL 0 5 2016 SURVEY REPORT BP Exploration H-Pad #H-25 Wellhead Prudhoe Bay, North Slope Borough, AK AK1215GCM191 8 December 2015 RIGHT PLACE FIRST TIME . www.gyrodata.com Gyrodata Incorporated • • gyro/cIata FrIouston,Texas 77095 Precision Wellbore Placement T: (281) 213-6300 • F: (281) 213-6301 December 17, 2015 State of Alaska - AOGCC Attn: Makana Bender 333 W. 7th Ave, Suite 100 Anchorage, Alaska 99501 Re: H-Pad, Well #H-25 Prudhoe Bay, Alaska Enclosed, please find one (1) copy, and one (1) disk of the completed survey for the above referenced well.

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.

Merv Liddelow (BP Rep.) performed the SVS tests today. Ail components functioned properly and held their pressure tests. The new style pilot boxes were installed on most of the wells, which combined with the reliability of the electronic pilOts~ helped to produce these great results. The well houses were all clean with pilot valves in proper pOsition. SUMMARY: I witneSSed the SVS test On twenty BPX H pad wells in the Prudhoe Bay Field. 20 wells, 40 components, No failures.

The well has communication between the inner and outer annuli and a hole 13-3/8" surface casing which precludes the use of gas lift. The well is shut in. An approach has been developed to repair the hole in the surface casing and return the well to gas lift. This program is as follows: 1) Set plug in XN nipple. 2) Pull uppermost gas lift valve. 3) Pump heated seawater (150 deg) down the inner annulus taking returns up the tubing to heat up the fluids in the outer annulus. 4) Down squeeze the outer annulus with Arctic Set cement, taking returns in the cellar using a vacuum truck. 5) Let cement set up for 48 hours. 6) Test outer annulus to 500 psi. 7) Test inner annulus to gaslift supply pressure. Observe outer annulus and area around the casing to ensure no gas is escaping. 8) Pull the XN plug, install a gas lift valve, and return the well to gas lifted production. Two other wells, H-07 and H-17, have been returned to gas lift service and production with this procedure. , .RE E VED .Oil & 6as Corls, Mch0ra~e LARRY GRANT Attn.

Comm. 3001 Porcupine Drive Anchorage, Alaska 99501 Dear Mr. Johnson: During testing operations on H-Pad on 3/27/94,~as found to have the P-Pilot Block Valve (Root Valve) closed. After me~tibg with John Spaulding on the same morning concerning the blocked P-Pilot on well H-25, a meeting was held that afternoon between Monte Townsend, Production Engineering Supervisor; Charlie Knapp, Field Supervisor and myself to determine the cause of the problem and find a solution. We are outfitting all our wells with a new and improved blanket that covers the P-Pilot manifold at the well head to keep the p-pilot system from freezing up which has been working quite well. The only explanation we can come up with for the blocked P-Pilot is it appears that when the blanket was installed, possibly the isolation valve was closed a few turns to initiate a tight fit on the blanket, and the installer didn't realize that they had completely shut off the valve. To prevent this from happening again, a memo is being distributed to all departments that work on our well heads. The memo will cover proper procedures for moving any valves without first contacting pad operator or appropriate personnel. Memo is attached for your review. We apologize for this problem and give you our assurance that everything will be done to insure that this problem does not occur again. We also thank Mr. Spaulding for meeting with us and allowing us to get right on top of the situation. It is this type of cooperation that will make a more efficient, safer field and that is what we are all striving for. Sincerely, Jerry L. Bixby Sr. WL and Completions Supv. RECEIVED JLB:kb Townsend/Walker- PE Supervisor Knapp- Field Supervisor APR - 1 1994 Alaska Oil & Gas Cons. Commission Anchorage Memomndum To: Distribution Date: 3/28~94 From: Field Supervisor Subject: WELL SAFETY SYSTEMS ************** COMPLIANCE WARNING *********** During State Testing on H-Pad 3/27/94, Well H-25 was found to have the P-Pilot Block Valve (Root Valve) closed. This isolates the P-Pilot from the S-Riser making the Well Head Safety System inoperative. This condition does not complify with State Regulations or BPX Policy and serious consequences can result. The Root Valve is rarely used during normal well house operations and is located beneath the Insulation Blanket/Box. It is not a daily check by Pad Operators due to the location. The primary use is during State Inspections, Repairs, or Calibrations. Following the ARCO Well Safety System Failure, all valves in BP Well Safety Systems were checked and verified to be in the normal operating positions. There was no rsason for this valve to be closed. No valves in Well Safety Systems will be left closed without the knowledge of the Pad Operator. All personnel working on Well Safety Systems are asked to double check the positions of all valves and other devices to make certain they are in service before completing any work on these systems. The Job is not complete until the system is verified to be functional! Charlie Knapp i~\~s~ ~ & ~s Co~s.
