Submit a well schematic diagram with each 10-407 well completion report and 10-404 well sundry report when the downhole well design is changed. Item 1 a• Classification of Service Wells: Gas Injection,Water Injection,Water-Alternating-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 ND 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).

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 a AOGCC order, or the terms and conditions of this permit may result in the revocation or suspension of the permit.

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 11,250' MD to 12,700' MD. Liner Program: • 3-1/4", 6.6# TCII x 3-1/2", 9.2# STL, L-80, solid liner 9,670' MD to 12,700' MD. • A minimum of 33.1 bbls of 15.8 ppg cement will be used for liner cementing (TOC 9,670' 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 103°, inclination at kick off point is 44°. • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • Distance to nearest property — 8,500' north. • Distance to nearest well within pool — 673' (15-27A). Logging • MWD directional, Gamma Ray and Resistivity will be run over all of the open hole section. • Cased hole GR/CCL/RPM logs will be run. • Open hole triple combo logs will be run after drilling to TD. 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 • F-41 fail major risk - no errors (parent well). • F-07 fail major risk (P&A'd well), pass minor risk - 1/10. Hazards • F-Pad is an H2S pad. • Most recent H2S level on F-39 is 140 ppm recorded on 1/16/2014. • Most recent H2S level on F-41 is 12 ppm recorded on 3/12014. • The lost circulation risk in F-41A is considered to be medium. Reservoir Pressure • The reservoir pressure on F-41A is expected to be 3,203 psi at 8,800' TVDSS. (7.00 ppg equivalent). • Maximum expected surface pressure with gas (0.10 psi/ft) to surface is 2,323 psi. • An EMW of 8.6 ppg for this well will provide 732 psi over-balance to the reservoir.
