This form is designed for submitting a complete and correct well completion report and log on all types of lands and leases in Alaska. 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).

During the cement job of the 2-3/8" liner, there was no indication that the LWP sheared. A subsequent cleanout run became stuck—500' into the liner. The BHA was intentionally released, and Nordic RDMO. Subsequent SL runs were not able to enter the liner, and returned cement samples well above the fish. Service CT attempted to enter the liner to mill out the suspected cement, but then subsequently left a 2nd fish in the TOL. that fish was subsequently recovered 500' into the liner(likely on top of the CTD fish). Service CT was then able to engage the CTD fish but was unsuccessful. . Proposed plan: Sidetrack B-05C to the B-05D location using Nordic 2 Coiled Tubing Drilling rig on or , around June 15, 2013. The B-05D sidetrack will exit the existing 3.5" liner and kick off in Zone 4 and land in Zone 2. This sidetrack will be completed with a 2-3/8" L-80 liner and cemented in place. This Sundry covers plugging the existing B-05C wellbore via the B-05D primary liner cement job and a liner top packer if the liner lap pressure test fails (alternate plug placement per 20 AAC 25.112(i)). The following describes work planned and is submitted as an attachment to Form 10-403. A schematic diagram of the proposed sidetrack is attached for reference. enD! will Gmfr- o f** e /ee7 (JhJS / 140 (esus (&Vie w rep free 074/25 Required Permit?

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.

' • Milling/drilling: 8.5 ppg Geo-VIS for milling window and drilling (-640 psi overbalance). Disposal: • All Class II drilling and completion fluids and all other Class II wastes will go to Grind & Inject at DS 4. • All Class I wastes will go to Pad 3 for disposal. Hole sizes: 3" 11,290' and— 13,820' and • Liner Program: Solid, cemented, and perforated completion. • 2-3/8", Chrome, 4.7 lb/ft STL liner, 10,700' and— 13,820' md. • Planned 13 bbls of 15.8 class G cement will be used for liner cementing (assuming 3" hole size to TD and 10% excess in open hole). TOC planned at 10,700 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 the 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 3500 psi. • The annular preventer will be tested to 250 psi and a minimum of 2500 psi. Directional • See attached directional plan. Maximum planned hole angle is 91°, inclination at kick off point is 87.6°. • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • Distance to nearest property—28,200 ft. • Distance to nearest well within pool— 1,415 from C-06B. Anti-Collision • B-05B • 1' (ctr—ctr distance) Status: Open perfs. Will have open perfs while drilling B-05C. • B-20 551' (ctr—ctr distance) Status: Open perfs. Will be plugged back prior to drilling C- 05C. Will be S/I and Locked Out/Tagged Out prior to drilling B-05C. Will stay shut-in until B-05C passes the Collision Risk. • B-20A wellplan 551' (ctr—ctr distance) Status: Will be drilled prior to B-05C. Will be S/I and Locked Out/Tagged Out prior to drilling B-05C. Will stay shut-in until B-05C passes the Collision Risk. • C-27 948' (ctr—ctr distance) Status: P/A • C-27A 518' (ctr—ctr distance) Status: P/A • C-27APB1 813' (ctr—ctr distance) Status: P/A 2 Logging • MWD directional, Gamma Ray and Resistivity logs will be run in the horizontal hole section. • • Cased hole GR/CCL/MCNL logs will be run. • Perforating • SWS 1.56", 6 spf, perf guns • 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 the hole. Hazards • The maximum recorded H2S level on B pad was 110 ppm on well B-21 (6/30/2011). Reservoir Pressure • The reservoir pressure on B-05C is expected to be 3,249 psi at 8,800' TVDss(7.1 ppg equivalent) • • Max expected surface pressure with gas (0.10 psi/ft)to surface is 2,369 psi. • • A EMW of 8.4 ppg for this well will provide —594 psi over-balance to the reservoir. .
