Attachments in Duplicate • • • bp Well: A-30 A-30 OA Cement&WeIlLock Squeeze Well Interventions Engineer: Travis Montgomery (918) 281-9663 Pad Engineer: Brian Glasheen (907) 545-1144 History A-30A is a gas-lifted Zone 4 producer. It has known scale downhole and downstream of the choke. The well has exhibited extensive tree glowth over time. In the second half of 2013, the well broke OA MOASP and showed rapid OA pressurization three times while starting up or shutting down and was declared not operable by the WIC. The IC primary seal was leaking in 2012 and 2013. In 2013, the secondary seal was leaking when well was shut-in and cold but holding when well was online and hot. The IC packoff was repaired with Seal-Tite in 2014 and 2016. Well had sustained OA casing pressure above Normal Operating Limit (NOL) on 7/12/17.-The OA pressurization is not manageable. Seal-Tite is no longer considered a long-term solution. A warm PPPOT-IC Passed on 7/20/17. Current Status The well is classified as "Not Operable" by BP due to the OA pressurization. The well is therefore currently shut-in until the leak is fixed. Objective Squeeze the OA with cement and WeIlLock to mitigate OA pressurization. Procedural steps Fullbore- 1st OA cement down squeeze 1. OA injectivity test. 2. OA down squeeze: • 13-3/8" x 9-5/8" annulus fry ' to surface = 156 bbls • Pump 180 bbls of Class G Cement Cement Design- 1st OA down squeeze BHST-40 deg F. SBHP--2199 psi BHCT-50 deg F Cement: Class G cement batch mixed. Density: 15.8 ppg Thickening time: Minimum 4 hours (2 hr pump time + 2 hr contingency) API Fluid Loss: 80-400 cc (40-200 cc/30 min) Free Water: 0 Compressive Strength: Minimum of 2000 psi Requested Volume: 180 bbls pumpable Fullbore-2nd OA cement down squeeze (if needed) 1. Pump a second cement job to refill OA to surface (if needed). ' Special Projects—OA WellLoc Queeze • 1. ND OA Gate Valves, NU OA Integrals. 2. Bleed Annuli (bleed IA as low as possible). 3. Prep OA, WeIlLock OA top job squeeze to 2500 psi per RP "WellLock Treatment for Cemented OAs." Note: The following are the well-specific equipment ratings that support squeezing to a higher pressure than usual (2500 psi). a. Burst of 13-3/8" 72# L-80: 5,380 psi, 80% is 4304 psi b. Collapse of 9-5/8" 47# L-80: 4757 psi, 80% is 3805 psi c. Casing packoffs tested to 3500 psi on 7/20/17. 4.

Operations personnel promptly bled the OA pressure from 1180 psi to 100 psi.The well was subsequently brought back online, and a follow-up monitor on 09/29/16 showed the OA pressure stable. Wellhead pressures were TBG/IA/OA= 570/1870/160 psi. Later on 09/29/16,the well was shut in again. A post-shut in monitor on 09/30/16 showed the OA nearly equalized with the IA. Wellhead pressures were TBG/IA/OA= 2000/1990/1960 psi. Downhole Diagnostics bled the OA to 0 psi, and the IA to 440 psi. A-30A has a history of IAxOA communication. When the well is online,the communication is manageable by bleeds. However, the communication has often been rapid when the well is shut in with high IA pressure. Diagnostics indicate that the leak path is via the wellhead. Specifically,the primary Inner Casing seal leaks, and the secondary IC seal holds when the well is online and warm, but leaks when the well is shut in. In July 2014, a Seal-Tite treatment of the inner casing seals mitigated the IAxOA communication. Post-treatment,the well was thermally cycled (shut in, monitored,then brought back online),with no signs of OA repressurization.The recent rapid repressurization when the well was shut in indicates that the Seal-Tite treatment has degraded. The well is reclassified as Under Evaluation for further diagnostics and repair. Plan Forward: 1. Downhole Diagnostics: Bleed OA and IA pressures—Completed 09/30/2016 2.

Both downhole diagnostics and the valve crew were nearby and responded immediately. The gas leak ceased once the valve crew tightened the first nut on the leaking flange. Once all of the flange nuts were tightened, a load and kill was performed on the well so that the flange could be torqued up. A downhole tubing tail plug has been set for secure for upcoming tree change out. Both a passing PPPOT-T and MIT-T were obtained yesterday on January 09, 2016 confirming the well is secure. Producer A-30A (PTD#2040780)was shut in at the time of the reported leak.The well is 95%water cut with minimal formation gas. I've included the last three well tests and the gas release calculations have been attached for reference. The leak was active for less than 24 hours and was equated to having a needle valve open a quarter of the way. The final estimate for gas volume release was 19.1 kg/hr.The incident investigation is currently ongoing. 7 17MScc/c ct Date Hrsi BFPD BOPD I IOR BWPD WC'.r ' TGLR FGLR ' Form GOR i GIL Rate GL FTP Temp J_ �___. _ ... __ I __ � — - __ _ �Gas Press 121372015 12 5,294 346 309 5,948 95 759 236 1,484 4,288 3,292 1,914 445 1-7-9- 11/21,2015 6 5,652 292 256 5,360 95 833 253 1,428 4,896 3,281 1,918 445 179 10/3112015 6 6,530 363 322 6,167 94 755 251 1,640 4514 3,233 1,922 448 178 Please let me know if you have any questions, comments, or concerns.

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.

The highest concentration currently on record is 200 ppm, measured in March 2000. ./ NORM test all retrieved well head and completion equipment. ./ Two wells, A-20 and X-06, fail to pass major risk criteria. These wells encroach the area of allowable separation within the reservoir. A-20 is currently shut-in awaiting RWO. X-06 is an injector, which may be shut in as needed. ./ The closest neighboring wells, at surface, are A-17 and A-18. Well A-17 is approximately 54' to the North. Well A-18 is approximately 56' to the South. No shut-in should be required, but care should be taken during rig MIRU and RDMO. Use spotters as necessary. ./ Due to sidetracking into the SV sands and drilling the West Sak, Colville, HRZ and Kingak shale, mud weight will be increased from 9.3ppg to 11.0ppg, and maintained at 11.0ppg through the HRZ, and the Kingak, to section TD. Monitor ECD closely. ./ There is one known fault crossing expected, during the drilling of the production interval of A-30A. No significant losses are expected, but due attention should be paid to the possibility. ./ The only fault related losses, in the surrounding area, during the drilling of the A- 30L 1 CTD well bore. The planned well trajectory of A-30A has been designed with sufficient standoff from the area of this event, but again, due diligence is warranted. The lost circulation decision tree should be followed if lost fluid returns are encountered. ./ Differential sticking may be encountered. Overbalance is approximately 600 psi. Always follow established drilling and connection practices for stuck pipe prevention. ./ Diesel will be used to freeze protect the well. The diesel flash point is 100° F. Diesel vapor pressure is - 0.1 psia at 100° F. CONSULT THE A-PAD DATA SHEET AND THE WELL PLAN FOR ADDITIONAL INFORMATION.
