In 1996 the Ivishak was frac'd and Sag perfs were added later that year. It produced steadily until 11-02-2006 when it was SI due to oil being found in the cellar and conductor. On 11-9-2006 an MIT-OA with N2 was attempted, but bubbling was seen in the conductor with the OA pressured to only 10 psi. Thus the well was secured with a TTP on 11-21-2006, passing an MIT-T to 3000 psi and a CMIT-TxIA to 3000 psi, both on 12-04-2006. On 11-01-2008 an MIT-OA to 500 psi with diesel passed, and then a month later on 12-5-2008 an MIT-OA to 500 psi with N2 passed, but bubbling was again seen in the conductor. A leak depth determination was performed in 2009, with comments indicating varying fluid levels in the OA, but none of the depths (1', 34', and 80') were believed to be the depth of the leak. A leak depth determination jn October 2014 indicated a leak in the SC a distance of 36-5/8" below - the top of the landing ring of the conductor. On 4-3-2015 the leak was attempted to be fixed by pumping/dumping 45 gallons of Well-Lock down the conductor, sealing the leak from the outside. This was unsuccessful, with a failing MIT-OA to 500 psi with N2 on 4-11-2015 and failed MIT-OA to 1200 psi with diesel on 4-17-15. During this last test liquid was forced up through the Well-Lock, being seen atop it. On 6-4-15 Well-Lock was again poured down the conductor, filling it up with 3.5 gallons. This second treatment was unsuccessful as well, with an MIT-OA with diesel to 120,0 psi failing on 6-13-15. The leak was successfully treated on 10-4-15 when 62 gallons of Seal-rite were pumped down the _OA._On the same day the well subsequently passed an MIT-OA to 1100 psi with diesel. The TTP was pulled and the well POP'd 11-7-15. The well req'd a couple of OA bleeds as it warmed up. As the well warmed up a mix of crude and water appeared atop the Well-Lock in the conductor. This began by being 1/8"-1/4" deep, requiring a rag to wipe it up. Through the course of 3 weeks this kept occurring, however the crude/water mixture dwindled to "trace amounts". This looked to be about to stop entirely, yet at this time the well was SI as per the WIC. On 2-9-16 the WeIlLock was air chiseled out. After a passing MIT-OA to 1200 psi the well was POP'd 3-17-16. A subsequent MIT-OA to re-engergize the SealTite failed, the well SI and classified as "not op" 3-18-16. An OA downsqueeze has been designed to remediate the SC leak. This program addresses that. Current Status The well is currently classified as "Non Operable" by BP due to the OA X Conductor leak. The well is therefore currently shut-in until the leak is fixed. Objective The objective of this job is to cement the OA (10-3/4" x 7-5/8") annulus, repair the OA x Conductor leak, and regain operability of the well. Cement will be pumped down the OA from surface in two stages (if needed). The goal is to have cement in the OA from the 10-3/4" casing shoe to surface. • Procedural steps Fullbore 1. Establish injectivity rate and pressure with diesel down the OA and into formation. Cementers 1. RU to the OA. 2. Pump enough Class G cement to fill OA to surface displacing OA fluid into formation. SI and allow cement level to reach equilibrium. 3. WOC to build strength. 4. Pump cement in stages to refill OA to surface (if needed). DHD 1. MITOA to 1200 psi. Operations 1. Put well on production. 2 • • lfilt= 4'5M UN VVELU-EAD= 13-5/8 RAC X-34 SAFETY NOTES:***CHROME T888.LNR"* - A CTUA TOR= BAKER OKB.ELEV= 68.55 , (' ,i ,,-, T 1 REF GB/= 68.55' ,i 1--z_ , 3 4 ' - - 20CONDUCTOR 110' —7 2090' —4-1/2'OTIS 1-1X0 SSSV NIP,ID=3.813' ] KOP= 1100 kto,Angle= 4.7. .„,3200 91.5#,I-1-40, , Datum MD= 11405' U=19.124' , ,- Datum TVD= 8800'SS11\ zAZ' GAS LIFT MANDRELS 10-3/4"CSG,45.5#,N1T-95 NSCQ ID=9.953' I— 3798' ST KC 'ND DEV TY PE VLV LATCH FORT DATE 6 3044 2726 46 KBMG-M COO& BK 16 11/07/04 L 5 5860 4664 46 KBMG-M DOW BK 16 02/18/96 Minimum ID =3.725" @ 11014' 4 8272 6318 46 KBM3-M COW BK 16 02/18196 4-1/2" oils XN NIPPLE 3 9763 7381 38 KBM3-M OW BK 0 02/18/96 2 10588 8096 25 KBM3-M OW BK 0 05/14/94 1 10843 8329 21 KF3MG-M SO BK 24 02/18/96 1 in—I 10948' —4-1t2"OTIS X NP,ID=3.813' Z X 10966' —7-5/8"X 4-1/2'I3KR SABL-3 RCP,1:3=3.93' 1 i—I 10997' —4-1/2'OTIS X NP,ID=3.813" 1 11 11014' —4-1r2-OTIS XN NP,ID 3125" TOP OF 5-1/2"LNER —{ 11023' r 11023' H5.75'BKR11133ACK SLV,ID= " 4-1/2'TBG,12154,13CR-80 NSCT, — 11024' / \ L. 11026' —4-1/7 YVLEG,C=3.958' .0152 bpf,0=3.958' 11014' SMD IT LOGGED avi 1/94 11030' —7-5/8'X 5-1/2'&KR H LTP w/SLH-6 I-IGR D= 7-5/8'CSG,29,7#, NT-95l- NSCC,C=6,875' H 11206' 14,32FORATION SUMAARY REF LOG: DFL-GR ON 01/09/94 ANGLE AT TOP PEW: 14-@ 11351' Note:Refer to Production CB for historical pert data SIZE SFF F(1ER(AL Opri/Sciz SHOT SQZ 3-3/8' 6 11351-11371 0 06/20/96 3-3/8' 6 11452-11482 0 03/11/94 3-3/8' 6 11510-11528 0 01/26/94 PBTD — 11634' , eZ' fZ 5-1/2"LIV :*,p R, 17#,13CR-80 FOX, —1 11765' s, ,0232 bpf,,ID=4.892' DATE REV BY COMENTS [ATE REV BY COMMENTS FRUDHOE BAY LNT 01/14/94 N-22E ORIGINAL COMPLETION 04/01/15 PJC LP/CSG/TBG LPATE TO TALLES: WELL X-34 07/17/01 RhYKAK CX)RRECTIONS 04/08/15 PJC ACO CONDUCTOR IWO PERMT No: 1931720 07/14/02 JC/KAK CORRECTIONS 11/02115,IMG111431FULLH)PXN RUG(10(30/15) AR No: 50-029-22417-70 11/07/04 KSFYTLF'GLV C/0 03/08/16 GCLAAD ADCED REF BLE./ SEC 6,T1ON,R13E,215'FSL&544'FEL - . 09/22/05pASJPAG)ABJ_HEAD CORRECTION 01/14/09 BSE/SV:RESET PXN PLUG(01/11/09) 8P Exploration(Alaska) 3 STATE OF ALASKA .LASKA OIL AND GAS CONSERVATION COMM!

In 1996 the Ivishak was frac'd and Sag perfs were background information, added later that year. It produced steadily until 11-02-2006 when it was SI due to oil being found in the etc: cellar and conductor. On 11-9-2006 an MIT-OA with N2 was attempted, but bubbling was seen in the conductor with the OA pressured to only 10 psi. Thus the well was secured with a TTP on 11-21-2006, • passing an MIT-T to 3000 psi and a CMIT-TxIA to 3000 psi,both on 12-04-2006. On 11-01-2008 an MIT-OA to 500 psi with diesel passed,and then a month later on 12-5-2008 an MIT-OA to 500 psi with N2 passed, / ✓ but bubbling was again seen in the conductor.A leak depth determination was performed in 2009,with comments indicating varying fluid levels in the OA,but none of the depths(1',34',and 80')were believed to be the depth of the leak. A leak depth determination in October 2014 indicated a thread leak in the SC a distance of 36-5/8" below the top of the landing ring of the conductor.On 4-3-2015 the leak was attempted to be fixed by pumping/dumping 45 gallons of Well-Lock down the conductor,sealing the leak from the outside.This was unsuccessful,with a failing MIT-OA to 500 psi with N2 on 4-11-2015 and failed MIT-OA to 1200 psi with diesel on 417-15. During this last test liquid was forced up through the Well-Lock,being seen atop it.On 6- 4-15 Well-Lock was again poured down the conductor,filling it up with 3.5 gallons.This second treatment was unsuccessful as well,with an MIT-OA with diesel to 1200 psi failing on 6-13-15. The leak was successfully treated on 10-4-15 when 62 gallons of Seal-Tite were pumped down the OA. On the same day the well subsequently passed an MIT-OA to 1100 psi with diesel.The TTP was pulled and the well POP'd 11-7-15.The well req'd a couple of OA bleeds as it warmed up.As the well warmed up a mix of crude and water appeared atop the Well-Lock in the conductor.This began by being 1/8"-1/4"deep, requiring a rag to wipe it up.Through the course of 3 weeks this kept occurring,however the crude/water mixture dwindled to"trace amounts".This looked to be about to stop entirely,yet at this time the well was SI as per the WIC. A sample of the Well-Lock has been analysed,and it is believed that the micro annuli in and around the Well-Lock enabled fluid beneath the Well Lock to wick up and collect on the surface. It is the purpose of this program to get rid of the micro annuli by boring out as much of the Well-Lock as possible and to re • - energize the Seal-Tite by pressuring-up the OA with a 1200 psi MIT-OA. • • • Well Intervention Details Suspected Well Problem: micro annuli iniaround Well-Lock wicking liquids to surface II Specific Intervention or Well Objectives: 1 Repair surface casing thread leak 2 3 Key risks,critical issues: Mitigation plan: 1 Spillage of liquids at surface Ensure containment,absorbant,etc are in place to contain spills 2 3 Summary Step# Service Line Activity 1 SP Remove Well-Lock from conductor. 2 DHD Re-energize Seal-Tite by performing MIT-OA 3 Detailed work scope(If no RP/SOP exists for the intervention type,a well-specific procedure is required in addition to the SOR): 1 SP Remove as much Well-Lock as is possible. Micro annuli are expected to be wicking liquids to surface. Removing the Well-Lock will remove the micro annuli. 1) Perform MIT-OA to 1200 psi with diesel.This will prove SC integrity whilst re-energizing the Seal-Tite 2 DHD that is already in the OA. 2) Bleed OA pressure to 300 psi and leave it that way.This will ensure the Seal-Tite remains energized. 3 Performance Expectations(may be NA if no change anticipated due to the intervention) BOPD: 285 MMSCFD: 2.5 BWPD: 2751 Expected Production Rates: FTP(psi): 250 Choke setting: 176 PI(bfpd/psi dp) Post job POP instructions: POP normally after WIC approval.

In 1996 the Ivishak was frac'd and Sag perfs were • background information, added later that year. In 2006 the operator noted bubbling in the cellar and the well was shut in for a surface etc: casing leak.A MIT-OA with nitrogen failed with bubbling at surface so the well was secured with a tubing tail plug. Several MIT-OA's have been attempted with both diesel and nitrogen and pass the pressure criteria, but all tests with nitrogen result in bubbling at surface.A leak depth determination was performed in 2009 and comments indicated varying fluid levels in the OA,but none of the depths(1',34',and 80')were believed to be the depth of the leak. A leak depth determination in October 2014 indicated a thread leak at 36-5/8" down from the landing ring. In April of 2015 the leak was attempted to be fixed by dumping well lock down the conductor and sealing the leak from the outside.The well lock was unsuccessful and actually made the leak visible with liquid.The Leak rate is 0.091 gpm at 500 psi and was not noticeable in the conductor to liquid prior to the well lock.The welllock filled the void space in the conductor and allowed the liquid to travel up the conductor and spill out on top of the well lock. • • Well Intervention Details Suspected Well Problem: Thread leak on first surface casing collar at 36-5/8".

The well fails MIT-OA to 500 psi with nitrogen. WeIlLock is a Newtonian resin that sets with temperature as an inert, hard, plastic-like material. The viscosity has been tested at 60 cP. The objective is to place the WeIlLock between the conductor and surface casing to mitigate the leak. Approximately two days before treatment, apply heater trunks to warm well to aid in treatment/curing of resin. Please reference the waste management plan, at the end of this document for disposal practice and approval. Ensure the slop trailer is clean prior to arrival. Do not mix non-exempt hydrocarbons with WeIlLock (this is to avoid taking WeIlLock to the facility). Well Detail Current Status: Not Operable — PAL Previous Test: 10-11-2014 MIT-OA to 500 psi (Nitrogen) Fail Integrity Issues: Surface casing leak via first casing spacer collar at 36 5/8" Last H2S Reading: 06-09-2006 30 ppm Well Operation Detail Fluid Density: WellLock: 9.1-9.3 ppg (keep WeIlLock at or above 85°F) Musol A: 7.5 ppg Diesel: 6.8 ppg Temperature: Maintain 75°-80° F throughout the entire job. Leave heater trunks in well during cure period (one week). Relevant History: > 10/11/14: MIT-OA w/ N2 Failed to 500 psi, LDD identified SC leak point at bottom of first SC collar. 36" down from top of conductor 1 of 3 Procedure 1 D Thoroughly clean the conductor by surface casing annulus to remove any deleterious material. This includes steam washing the annulus and cleaning with detergent. 2 D Run open bleed on OA during the entire job. 3 D ***Pump WeIlLock into conductor by casing annulus. 4 D Allow WellLock to cure for one week. 5 D MIT-OA to 500 psi. *** Collect approximately one cup sample of WellLock in disposable container. Place sample in representative condition and monitor viscosity throughout job. Leave sample during seven day cure period and record temperature and observable viscosity of sample. 2 of 3 11 4514 LAMLICN WI.LLFEAD 13-5/8 FMC X-34 SAFETY NOTES'"•CHROME TEC&LNR' • A CADA I OK SAKtli KB.LLEV 67 04' BF.LLt.V 26r KOI' 11(XY NIP. 36,:r" I 2090' I-14.1.2-U I F.;HX7j SS"Sf..

Supervisor THRU' FROM: Jeff Jones, SUBJECT: Petroleum Inspector December 9, 2000 Safety Valve Tests Prudhoe Bay Field BPX / X-Pad SatUrdayi December 9, 2000: I traveled to BPX's X Pad in the Prudhoe Bay Field to witness Safety Valve System tests. Merv Liddelow, BPX representative in charge of the testing, performed the tests in a safe and proficient manner. Of the 26 wells tested, 3 failures were witnessed. Well X-14A's SSV failed to close and well X-19B's pilot was frozen and the SSV failed to close. Mr. Liddelow indicated to me on 12/10/00 that these items have been corrected and successfully re-tested. The AOGCC test reports are attached for reference. I conducted 26 well house inspeCtions concurrent with the SVS tests. A slight crude oil leak was noted on a wellhead flange of well X-19B. Mr. Liddelow indicated he would have this item addressed. No other exceptions were noted. SUMMARY: I witnessed SVS tests and conducted well house inspections on BPX's X Pad. 26 wells, 53 components teSted, 3 failures. 26 Well houses inspected.

The Test commenced at 1:30 AM and was concluded at 4:30 AM. As the attached AOGCC BOPE Test Report indicates/there were no failures. The H2S gas detection was disabled while waiting on upgrade parts. The drilling permit indicated that H2S detection was no~'required on this well. The IOBP had failed on the last test witnessed by John Spaulding, the valve was replaced but the toolpusher had failed to call John and inform him of the replacement and retest. I noted this on the test form and left note to that effect for John. Summary: I witnessed BOPE test on Nabors 22E test time 3 hrs, no failures, 25 valves tested.

The well is being plugged back because of hole wash out in the Kingak Shell formation and tight h°le in the Sag, Shubik and Sadlerochit formations. There was no cementing procedure at the site however I talked with Blair Wondzell and he gave BPX verbal approval to proceed with the cementing operations. I witnessed the tagging of the first stage of the Open Hole plug ~10:00 PM this date. The plug was set from TD @ 11,675 ft. and tagged with 20,000 pounds of drill string weight @ 11,333 ft. Tuesday January 4, 1994: After waiting on cement for 12 hours I witnessed the tagging of the second stage of the Open Hole Isolation plug. This plug was set from 11,333 ft. and tagged with 20,000 pounds of drill string weight @ 11,271 ft.. The plug was originally planned to extend 100 ft. inside the 7 5/8" casing, however the washed out area in the Kingak Shell formation was larger than expected leaving the second stage plug 67 ft. short of the 7 5/8" casing shoe. A third cement plug was set to extend 400' inside the 7 58" casing and the decision was made to redriil the original wellbore and not cut a window for a new bottom hole location. I was unable to witness the tagging of this third plug due to other work. I did witness the ROPE test on this rig prior to redrilling operations. Summary: I witnessed the tagging of two cement plugs at BPX PBU X-34 well on Nabors Rig 22E. STATE OF ALASKA ALASr-,A OIL AND GAS CONSERVATION COMMISSI~,~ APPLICATION FOR SUNDRY APPROVALS 1.

The open hole logs could not be run successfully to TD with E-line. After repeated attempts with E-line, the deepest the tool was able to get was 11,362', It was then decided to run a gamma ray Icg through drill pipe to determine the tops of the formations in open hole. Upon completion of the gamma ray logs, the tops of the formations were determined to be ~70' deeper than expected. After the tops of the formations were confirmed, a gyro was run inside drillpipe to confirm the bottom hole location. After examination of the gyro data, it was found that the bottom hole location was approximately 300' to the North and 50' to the West. A balanced cement plug of 174 bbls was set over the open hole interval to in three stages to approximately 300' within the 7- 5/8" casing at 10905'. An attempt will be made to drill out the cement and redrill the production hole to approximately the same bottom hole location beginning January 5, 1994. Once the well is drilled to TD, E-line open hole logs will be run to determine whether the well will be completed.

OPEN HOLE CASING DRILLERS BIT SIZE (IN) SIZE (IN) DEPTH (FT) 3 SEPARATE ATTEMPTS WERE MADE TO LOG THIS WELL IN OPEN HOLE CONDITIONS WITH DIFL/AC/GR TOOL STRING. HOLE CONDITIONS WERE SUCH THAT IT WAS NOT POSSIBLE TO GET BELOW 11362'. ANY OPEN HOLE DATA GATHERED IN THESE SHORT INTERVALS WAS DEEMED INVALID. A GR/CCL LOG WAS RUN THROUGH 3.5" DRILL PIPE IN ORDER TO ESTABLISH FORMATION TOPS. SINCE THE CCL WAS RUN INSIDE DRILL PIPE IT IS ALSO INVALID. NOTE THAT THE ENTIRE LOG IS CONSIDERED CASED HOLE EVEN THOUGH IT GOES BELOW CASING SHOE (SINCE LOGGED IN DRILL PIPE). ONE OF THE ATTEMPTED OPEN HOLE LOGGING PASSES WAS RUN UP INTO CASING HIGHER THAN ANY OTHER SUBSEQUENT PASS. THE GAMMA RAY FROM THAT PASS IS INCLUDED HERE TO GET THE MAXIMUM GR COVERAGE POSSIBLE. THE FINAL MERGED GRCH CURVE CONSISTS OF: 10~48 - 11194 from CASED HOLE portion of attempted OPEN HOLE PASS. 11194 - 11563 from GR/CCL run inside drill pipe. THIS WELL WAS PLUGGED BACK & SUBSEQUENTLY SIDETRACKED (X-34ST DATED 09-JAN-94). THE KICK OFF POINT FOR THE SIDETRACK IS BELOW THE CASING SHOE. THEREFORE THE CASED PORTION OF X-34 & X-34ST ARE THE SAME HOLE. X-34ST WAS RUN USING MARKED LINE & THE GR FROM IT IS CONSIDERED THE DEPTH REFERENCE. FOR THIS REASON THE DATA FROM THIS WELL, X-34, WAS DEPTH MATCHED TO THE GR FROM X-34ST OVER THE CASED HOLE PORTION OF THE WELLS. THE GRCH COVERAGE FROM X-34 GOES BOTH ABOVE & BELOW THAT FROM X-34ST. DEPTH SHIFTS WERE EXTRAPOLATED TO TOP & BOTTOM LOGGED INTERVALS FROM THE OVERLAP OF X-34ST.
