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 la: 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.

Pat E---57 AL I Zio-bbl To whom it may concern, On July 3rd 2010 at 0030hrs during a Whipstock setting trip, Nordic 1 experienced a false alarm on the H2s alarm system. The sensor in the cellar had detected the gas and set off the evacuation alarm. The rig team responded quickly by shutting down the pump and closing the HCR on the choke side of the BOP stack. The rig was then evacuated and notifications were made. The fire department arrived and cleared the rig. Upon re-entry it was discovered that the H2s sensor in the cellar was wet due to Hands cleaning in the cellar. The sensor was cleaned and dried then re-tested. The test was successful. Normal Operations continued at 0230hrs. At 0730hrs a call was placed to discuss this incident with the AOGCC State Inspectors John Crisp and Jeff Jones.

April 28,2010 E-37AL1 — Coiled Tubing L ling Mud Program: • Well kill: 8.6 ppg brine • Milling/drilling: 8.6 ppg Geo-Vis or biozan for milling, new Geo-Vis for drilling. Disposal: • All drilling and completion fluids and all other Class II wastes will go to Grind & Inject. • All Class I wastes will go to Pad 3 for disposal. Hole size: 4-1/4" • Casing Program: • 2-7/8", 6.4#, L-80, STL slotted liner— 10,900'MD— 12,850' MD. , Well Control: • BOP diagram is attached. • Pipe rams, blind rams and the CT pack off will be pressure tested to 250 psi and to 3500 psi. • The annular preventer will be tested to 250 psi and 2500 psi. Directional: • See attached directional plan. Maximum planned hole angle is 90 deg. • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • Distance to nearest property line— 10,150' • Distance to nearest well in pool - 480' (G-13 P&A) Anticollision Summary: • G-13—416' ctr-ctr Status: Abandoned • G-13A - 453' ctr-ctr Status: LTSI Logging • MWD directional, Gamma Ray, and Resistivity will be run over all of the open hole section. • A cased hole MCNL log will be run. Hazards • The maximum recorded H2S level on E Pad is 120 ppm on E-102 (09-16-2008). E Pad is not an H2S pad. • Lost circulation risk is medium. No fault crossings are expected. Reservoir Pressure • Res. pressure is estimated to be 3,250 psi at 8,940' TVDss (7.0 ppg EMW). Maximum surface pressure with gas (0.10 psi/ft) to surface is 2356 psi.

(3) All True vertical Depths (TVDSS) are subsea corrected. (4) All Formation Evaluation data is realtime data. (5) Baker Hughes INTEQ utilized CoilTrak downhole tools and the Advantage surface system to log this well . (6) Tools ran in the string included Casing Collar Locator, an Electrical Disconnect and Circulating Sub, a Drilling Performance Sub (Inner and Outer Downhole Pressure, Vibration and Downhole weight on Bit) , a Directional and Gamma Sub, and a Hydraulic Orienting Sub with a Near Bit Inclination Sensor. (7) Data presented here is final and has been depth shifted to a Primary Depth Control (PDC) log provided by Schlumberger GR CNL dated 10 Jul 2010 per Jennifer Flight with BP Exploration (Alaska) , Inc. (8) The sidetrack was drilled from E-37A through a milled window in a 4 1/2 inch liner. Top of window 10880 ft.MD (8939.8 ft.TvDSS) Bottom of window 10888 ft.MD (8941.1 ft.TvDSS) (9) Tied to E-37A at 10874.1 feet MD (8938.7 feet TVDSS) . (10) The interval from 12753 ft to 12803 ft MD (8936.2 ft. to 8937.8 ft. TVDSS) was not logged due to sensor to bit offset at well TD.
