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) Item 28: Provide a listing of intervals cored and the corresponding formations,and a brief description in this box.

The permit is for a new wellbore segment of existing well Permit No. 199-081, API No. 50-029- 21964-01-00. Production should continue to be reported as a function of the original API number stated above. This permit to drill does not exempt you from obtaining additional permits or an approval required by law from other governmental agencies and does not authorize conducting drilling operations until all other required permits and approvals have been issued. 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.

The W-26AL1 sidetrack will be a single string exit J through the existing 4-1/2" liner and kick off horizontally into Zone 4. The proposed sidetrack is a —2295' horizontal Zone 4 producer, which will access Zone 4 reserve targets in W-pad. The lateral will be completed with a 3-1/2" 13Cr solid by 2-7/8" 13Cr solid liner and will be cemen d to the top of the liner at 11,350' MD and selectively perforated. The existing perf intervals (11150'-11175', 11178'-11198', 11222'-11242', 11250'- 11264', 11276'-11293') are expected to be damaged during the liner cement job and they will be re-perfed. Rig Work(scheduled to begin September 15th,2014) 1. MIRU and test BOPE 250 psi low and 3,500 psi high (MASP 2,780 psi). 2. Pull BPV and bullhead kill well. 3. Set 4-1/2" KB packer whipstock at 12,230' MD. 4. Mill 3.80"window and 10' of rathole. 5. Drill build/turn: 4.25" OH, 599' (25° DLS planned). 6. Drill lateral: 4.25" OH, 1,696' (12° DLS planned). 7. Perform OH triple combo logging (as hole conditions permit). 8. Run 3-1/2" 13Cr x 2-7/8" 13Cr liner leaving TOL at—11,350' MD. 9. Pump primary cement job: 31 bbls, 15.8 ppg, TOC at—11,350' MD. 10. Perform liner cleanout and GR/CCL log (MCNL or MRPM if OH logs fail). 11. Perforate liner based on log interpretation. 12. Freeze protect well to 2,500' MD. 13. Set TWC; RDMO. Post-Rig Work: 1. Re-install wellhouse, flowline and pull TWC. 2. Install generic GLV design. 3. Set liner top packer with slickline. 4. ASRC flowback. Mud Program: • Well kill: 8.4 ppg brine. • Milling/drilling: 9.5 ppg PowerVis for milling window and drilling (686 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 12,230' MD to 14,525' MD • Liner Program: • 3.5", 9.3 lb/ft, 13Cr, STL Solid liner 11,350' MD - 11,400' MD. • 2-7/8", 6.5 lb/ft, 13Cr, TH511 Solid liner 11,400' MD - 14,525' MD. • A minimum of 31 bbls of 15.8 ppg cement will be used for liner cementing (TOC 11,350' 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 111.9°, inclination at kick off point is 97.3°. • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • Distance to nearest property— 15,500'. • • Distance to nearest well within pool —770'. ' Logging: • MWD directional, Gamma Ray, and Resistivity will be run over all of the open hole section. • Open hole Res/Gamma/Density Neutron logs are planned if wellbore conditions allow. • Cased hole GR/CCL logs will be run. Either an MCNL or RPM log will be run if the open hole triple combo is unsuccessful. Perforating: • SWS 2", 6 spf, perf guns, 1-1/4" CSH work string, &2-3/8" PH6 • 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: • W-26 Grandparent well at 12,815' MD (79' center-to-center). Hazards: • W-pad is considered to be an H2S pad. • W-26 had 13 ppm H2S on 2/08/2013. • The lost circulation risk in W-26AL1 is considered to be medium due to open perforations in the parent & one planned fault crossing. Reservoir Pressure: • The reservoir pressure on W-26AL1 is expected to be 3,661 psi at 8,800' TVDSS (8.0 ppg equivalent). • Maximum expected surface pressure with gas (0.10 psi/ft) to surface is 2,781 psi. • An EMW of 9.5 ppg for this well will provide 686 psi over-balance to the reservoir.
