All laboratory analytical reports regarding samples or tests from a well must be submitted to the AOGCC, no matter when the analyses are conducted. Item Ia. 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 1b. Well Class Service wells: Gas Injection, Water Injection, Water -Alternating -Gas Injection, Salt Water Disp, Water Supply for Injection, Observation or Other Item 41b. TPI (Top of Producing Interval). Item 9. The Kelly Bushing and Ground Level elevations 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 15. 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 MO and TVD for the top and base of permafrost in Box 29. Item 22. Review the reporting requirements of 20 AAC 25.071 and, pursuant to AS 31.05-030, submit all electronic data and printed logs within 90 days of completion, suspension, or abandonment, whichever occurs first. Item 23. Attached supplemental records 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. Item 31. Pursuant to 20 AAC 25.070, attach to this form: well schematic diagram, summary of daily well operations, directional or inclination survey, and other tests as required including, but not limited to: core analysis, paleontological report, production or well test results.

A RWO was performed in November 2009 to repair a surface casing leak and the 7%' production casing was replaced with new casing with premium connections, which was cemented to surface. The 4%" tubing was also replaced with chrome tubing with premium connections. A CTD sidetrack is planned for November 2017. Scope of Work: The objective of this intervention is to utilize Service Coil and the Well Work Platform to add 1500' of perforations post rig after CTD drills, completes, and cements the well. Proposed WWP Procedure: • MIRU WWP, BOPE and support equipment • MIRU CTU • Test BOPE with four preventers configured top down (annular, blind shears, 1.75" pipe/slips, mud cross, 2-3/8" x 3-1/2" VBR's, 1.75" pipe/slips). Test the blind shears, VBR's, and pipe slips to 3500 psi and the annular to 2500 psi.

Approval is requested for a permit to drill a CTD sidetrack from well R -28A by the Nabors CDR2 Drilling rig on or around June 1, 2017. The R -28A sidetrack will be a single string exit from the existing 5%" liner. A 4%" x 5'/" Delta Whipstock will be set above a PosiSet plug, which will allow isolation from the Ivishak perforations. R -28A will kickoff from 5'/:" liner drilling a horizontal well to provide offtake in the target fault block across the Sag River sands. Well design involves kicking off a 4%" x 5%" Delta whipstock, drilling build section with 35 DLS, drilling lateral with 12 DLS geosteering in the Sag River, run 3%" x 3'/e" x 2%" 13Cr-85 production liner, cemented and perforated.

(TOC at 8,920' MD) - • The primary barrier for this operation: minimum EMW of 8.4 ppg (provides 536 psi overbalance) • A cross 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 packoff will be pressure tested to 250 psi low and 3,500 psi high. • The annular preventer will be tested to 250 psi low and 3,500 psi high. ✓ Directional: • See attached directional plan. Maximum planned hole angle is 110°. • Magnetic and inclination surveys will betaken every 30 ft. No gyro will be run. • Distance to nearest property line: 14,050' • Distance to nearest well within pool: 100' TVD (R-29A Ivishak horizontal production hole crosses 100' TVD below R-28A Sag horizontal section) -" Logging: • MWD directional, gamma ray, and resistivity will be run over all of the open hole section. Perforating: • HES MaxForce 2.00", 6 spf, perf guns, 1" 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: • R-14 Fails Major Risk for R-28A WP08 Anti-Collision. R-14 has been P&A'd due to sidetrack and has been minor risked. • R-14A Fails Major Risk for R-28A WP08 Anti-Collision. R-14A has been P&A'd due to sidetrack and has been minor risked. • R-29A Fails Major Risk for R-28A WPO8 Anti-Collision. R-29A will be shut-in and minor risked. Hazards: • R-Pad is considered a H2S pad • Most recent 112S level on R-Pad was at R-29A with 100 ppm recorded on 8/21/2016 • Lost circulation potential in R-28A is considered to be med (2 mapped fault in target location) Reservoir Pressure: / • The reservoir pressure on R-28A is expected to be 3,350 psi at 8,900' TVDss. (7.24 ppg EMW) ✓ • Maximum expected surface pressure with a full column of gas (0.10 psi/ft) to surface is 2,461 psi. • An EMW of 8.4 ppg will provide a 536 psi overbalance to the reservoir. Managed Pressure Drilling: • MPD techniques may be used to improve hole stability. • An automatic choke will maintain a target ECD at the window for the duration of drilling to improve hole stability. • A pressure schedule will be used for tripping In/Out of the hole. The purpose of the pressure schedule for tripping is to maintain the same bottom hole pressure at the window by applying surface pressure via the choke. • At all times, drilling fluid weight will be greater than equivalent pore pressure. MPD is only being used for hole stability. Jacob Leemhuis CC: Well File CTD Engineer Joe Lastufka Jacob.Leemhuis@bp.com 907-564-4989 TREE = CNV WELLHEAD= FMC ACTUATOR= BAK92 NRAL KB. E.E _ 51.7 BF.
