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 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.

Field Superintendent Name: Richard Burnett Wellsite Leader Name: Ken Miller Contact Number: 907.659.5329 Contact Number: 907.659.4393 Traction Number: 2012-IR-4108578 Well Location/Name & Rig Name: DS 15-09B — Nordic 2 - Permit To Drill (PTD) Number: 212-024 - Date and Time of Incident: 04/16/2012 @ 04:15 HRS Original Scope of Work: Displace well bore fluids on P&A'd well prior to milling cement plug for a CTD sidetrack. Operational Description Leading up to Well Control Event: While running in hole with coil tubing to displace existing fluid prior to milling operation, an increase in returns from the well was noted. The rig manual choke was shut and wellhead pressure increased to ^ 140 psi and stabilized. BOPE Used and Reason: Manual choke was closed to monitor the well head pressure Is a BOPE Test Required after use ( Yes/ No): Yes If no, why? 24 hour notice required to NS AOGCC Inspectors prior to testing BOPE components. Plan Forward: Circulate trapped gas out of wellbore. Re-test manual choke and proceed with milling operation Additional Comments: Additional gas circulated out when coiled tubing reached 7971' MD before commencing cement milling operations.

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

Reservoir Pressure • The reservoir pressure on 15-09A is expected to be 3,313 psi at 8,800' TVDSS. (7.2 ppg equivalent). • Maximum expected surface pressure with gas (0.10 psi/ft) to surface is 2,433 psi. ✓ • An EMW of 8.4 ppg for this well will provide 530 psi over-balance to the reservoir.
