• Flu t 7_ c- u Regg, James B (DOA) 0r�0 From: AK, GWO SUPT Well Integrity <AKDCWellIntegrityCoordinator@bp.com> Sent: Monday, September 12, 2016 7:45 AM / V 'e, To: Regg,James B (DOA) 2 /6 Cc: Wallace, Chris D (DOA); Daniel, Ryan; Cismoski, Doug A Subject: Producer 17-04C (PTD#2150170) OA Casing Pressure Above MOASP Jim, On 09/08/16, a pumping crew was on location at Producer 17-04C (PTD#2150170), in order to freeze protect the flowline.The crew noticed that a quarter-turn valve upstream of the outer annulus (OA) pressure gauge was closed, isolating the gauge from the OA. Upon opening the quarter-turn valve, the OA pressure was found to be 1600 psi.The gauge was reading 560 psi prior to opening the valve.The well has known, manageable, OA repressurization, with a build-up rate of approximately 30 psi per day. Well Integrity and Operations field leadership were notified.The Operator bled the OA from 1600—300 psi.The following day, Downhole Diagnostics bled down the IA. Pressures have remained stable since. An investigation is currently ongoing within Operations. Please call with any questions.

Item la: Classification of Service Wells: Gas Injection,Water Injection,Water-Altemating-Gas Injection,Salt Water Disposal,Water Supply for Injection, Observation,or Other. Multiple completion is defined as a well producing from more than one pool with production from each pool completely segregated. Each segregated pool is a completion. Item 4b: TPI(Top of Producing Interval). Item 8: The Kelly Bushing and Ground Level elevation in feet above mean sea level. Use same as reference for depth measurements given in other spaces on this form and in any attachments. Item 13: The API number reported to AOGCC must be 14 digits(ex: 50-029-20123-00-00). Item 20: Report true vertical thickness of permafrost in Box 20. Provide MD and TVD for the top and base of permafrost in Box 28. Item 23: Attached supplemental records for this well should show the details of any multiple stage cementing and the location of the cementing tool. Item 24: If this well is completed for separate production from more than one interval(multiple completion),so state in item 1,and in item 23 show the producing intervals for only the interval reported in item 26. (Submit a separate form for each additional interval to be separately produced, showing the data pertinent to such interval). Item 27: Method of Operation: Flowing,Gas Lift,Rod Pump,Hydraulic Pump,Submersible,Water Injection,Gas Injection,Shut-In,or Other(explain). Item 28: Provide a listing of intervals cored and the corresponding formations,and a brief description in this box. Submit detailed description and analytical laboratory information required by 20 AAC 25.071. Item 30: Provide a listing of intervals tested and the corresponding formation,and a brief summary in this box. Submit detailed test and analytical laboratory information required by 20 AAC 25.071.

In addition, the AOGCC reserves the right to withdraw the permit in the event it was erroneously issued. Operations must be conducted in accordance with AS 31.05 and Title 20, Chapter 25 of the Alaska Administrative Code unless the AOGCC specifically authorizes a variance. Failure to comply with an applicable provision of AS 31.05, Title 20, Chapter 25 of the Alaska Administrative Code, or an AOGCC order, or the terms and conditions of this permit may result in the revocation or suspension of the permit.

Rig Work (scheduled to begin March 5th, 2015) 1. MIRU and test BOPE 250 psi low and 3,500 psi high. (2,689 psi MASP). 2. Mill 3.8" window at 10,520 MD and 10' of rathole. • 3. Drill build section: 4.25" OH, —450' (30° deg/100 planned). 5. Drill lateral section: 4.25" OH, —2560' (12° deg/100 planned) with resistivity. • 6. Run 3-1/2" x 2-7/8" 13Cr liner leaving TOL at 10,150' MD. Pump primary cement leaving TOC at TOL (-10,150' MD), 35.8 bbls of 15.8 ppg liner 7.* cmt planned. 8. Perform liner cleanout with mill, motor and GR/CCL log. 9. Perforate liner based on log interpretation (-500' of perfs) 10. Freeze protect well to 2500' MD 11. Set BPV, RDMO *Approved alternate plug placement per 20 AAC 25.112(i) Post-Rig Work: 1. Re-install wellhouse, flowline and pull BPV. 2. Set liner top packer with Slickline (if needed) & test to 2,500psi. 3. Set generic GLV's, SBHPS, ASRC flow back, SIT. Mud Program: • Well kill: 8.4 ppg brine. • Milling/drilling: 8.6 ppg PowerVis for milling window and drilling (366 psi over-balance). Disposal: • All Class I & II non-hazardous and RCRA-exempt drilling and completion fluids will go to GNI at DS 4 or Pad 3 at DS 6. • Fluids >1% hydrocarbons or flammables must go to Pad 3. • Fluids >15% solids by volume must go to GNI. • Fluids with solids that will not pass through 1/4" screen must go to GNI. • Fluids with PH >11 must go to GNI. Hole Size: • 4.25" from 10,520' MD to 13,535' MD. Liner Program: • 3-1/2", 9.2# STL 13Cr x 2-7/8" 13Cr 6.5# STL, solid liner 10,150' MD — 13,535' MD. • A minimum of 35.8 bbls of 15.8 ppg cement will be used for liner cementing (TOC 10,150 MD). • The primary barrier for this operation: a minimum EMW of 8.4 ppg. • A X-over shall be made up to a safety joint including a TIW valve for all tubulars ran in hole. Well Control: • BOP diagram is attached. • Pipe rams, blind rams and the CT pack off will be pressure tested to 250 psi and to 3,500 psi. • The annular preventer will be tested to 250 psi and 3,500 psi. Directional • See attached directional plan. Maximum planned hole angle is 95°, inclination at kick off point is 69°. • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • Distance to nearest property— 9,950'. • Distance to nearest well within pool 780'. . Logging • MWD directional, Gamma Ray and Resistivity will be run over all of the open hole section. • Cased hole GR/CCL logs. Perforating: • SWS 2" PJ 6 spf perf guns, 1-1/4" CSH work string, & 2-1/16" CSH. • The primary barrier for this operation: a minimum EMW of 8.4 ppg. • A X-over shall be made up to a safety joint including a TIW valve for all tubulars ran in hole. Anti-Collision Failures • 17-04B PB1 fails major risk. No errors, parent well and fails at KOP. Hazards • Drill Site 17 is an H2S pad. • Most recent H2S level on 17-04B is 170 ppm recorded on 6/9/2012. • The lost circulation risk in the 17-04C is considered to be low. Reservoir Pressure • The reservoir pressure on 17-04C is expected to be 3,569 psi at 8,800' TVDSS. (7.8 ppg equivalent). • Maximum expected surface pressure with gas (0.10 psi/ft) to surface is 2,689 psi. • An EMW of 8.4 ppg for this well will provide 275 psi over-balance to the reservoir.
