History of 18 -13B. 18 -13B is a 2007 horizontal CST in Zone 1A in the Ivishak. After drilling three plugbacks, the well was finally completed in an area very close to a well with high offtake. The well was brought online in Feb 2008 and started to cycle immediately and the gas rate peaked after the well's first cycle. A Spinner- Temp -Press log was run over the liner lap region in March 2008. It indicated the liner top was not leaking. In May 2008, STP/MCNL/Borax logs were performed to diagnose the source of gas production in 18- 13B, but no channels were identified and no significant point- source entry of gas was found. In Aug 2008, a CIBP was set over 930' of the lower perfs at 10,540' leaving 150' of the upper perfs open. The CIBP was not successful in reducing the gas but did reduce the oil, and the well was once again shut -in for high GOR. The well has been brought online twice in the last two years with high GOR. The well showed no ability to cycle and remains shut -in for high GOR. Due to low remaining value, 18 -13B was screened for a CST in May 2010. Reason for sidetrack. 18 -13A is currently SI for high GOR with no remaining wellwork options. The V proposed sidetrack will access reserves in the south eastern portion of the Ivishak. Proposed plan for 18 -13C is to drill a thru- tubing sidetrack with a Coiled Tubing Drilling rig on or around January 10, 2011. The existing perforations will be isolated by the primary cement job. 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. j orate.

This permit supercedes that of 18-13AL 1, Permit No 207-134. Due to the loss of mechanical equipment in hole, 18-13AL1 cannot be drilled. Beginning operations on 18-13B prior to receipt of this permit was authorized by commissioner Seamount on November 6, 2007 per 20 AAC 25.005. 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. When providing notice for a representative of the o mission to witness any required test, contact the Commission's petroleum field ' spe or at (907) 659-3607 (pager).

In the process of running the whipstock for 18-13 AL1, the whipstock became stuck at roughly 8800'. Fishing operations were unsuccessful, so the fish was pushed downhole to an X nipple at 9234, at which point it became permanently stuck. This requires a change in scope of the CTD sidetrack proposal. Verbal approval was received from the State (reference attached a-mail from Art Saltmarsh dated 10/6/2007) to pursue a new permit to drill for 18-13B. Rig Operations: Nordic 2 rigged up on the 18-13 A wellbore on 10/30/07 under Permit to Drill #207-134 for PBU 18-13 AL1 Verbal approval received from AOGCC (ref: Art Saltmarsh Email 11/06/07) to change the drilling plan and BHL Scope revised to drill the proposed PBU 18-136 as follows: 3~1~_ '3 L~t~ Point forward Rig Work: (as of 10/6/2007) -rig currently on location 1) Perform cleanout runs and dummy whipstock run to 9200 ft 2) Set 4-1/2" Baker Monobore WS at 9200' 3) Drill Build: 4.125" OH, 730' (15 deg/100 planned) 4) Drill Lateral: 4.125" OH, 2770' (12 deg/100 planned) 5) Run 3-3/16" X 2-7/8" solid liner targeting TOL at 8600' 6) Pump primary cement job to TOL, 39 bbl of 15.8 ppg cmt planned 7) Run cleanout assembly 8) Run MCNL/GR/CCL log 9) Test liner lap to 2000 psi. 10) Perforate, planned 1500ft. 11) Freeze protect well with diesel, set BPV, and RDMO Post-Rig Work: 1) Pull BPV 2) Install well house, flow line, and gas lift valves Mud Program: • Well kill: 8.6 ppg brine • Milling/drilling: 8.6 ppg Flo Pro or biozan for milling, new Flo Pro for drilling.

The 18-13AL1 original scope was to exit the existing Nner at 11250' MD, dose to horzontai, tam and dnil! a horizontal lateral to the north. The proposed completion strategy was to complete with a sbtted 6r~er with an openhole junction at the window, and retrieve the whipstock to allow future rye-entry into the parent welltxue In the process of running the retrievable whipstock, it became stuck in the we#bore and we have been unable to pail it out of the hole. iNe were sucxessful in pushing if downhole to 9235, but have decided the best course of action from here wark! be to change the soaps of this sidetrack. We are currently developing a plan to set a whipstock at 9200 ft, MD, mill a window and directiortaayr drift to the target Zone 1 horizon and drill a new horizontal lateral to a MD of 12700' MD. The new BHt_ will be located roughty halfway between the 18-13A and the proposed 18-13 AL1 permitted BHL(greater than 500 feet away):; Because of the change in KOP, the current proposed completion will be a Demented and perforated liner. As such, the parent 18-13 A wellbore will be isolated by the r.~emertt and the new welibore wfil be Warned i 8-138. We request verbal permission to pursue this near proposed scope and will follow with a formal revised permit to drill for the 18-138 as soon as we can complete the plans. Lamar L.

(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 adjusted to a PDC (Primary Depth Control) log from well 18-13BPB1 above the KOP (Kick Off Point) of 9970 feet MD per Doug Stoner with BP Exploration (Alaska), Inc. (8) Tied to 18-13A at 9155 feet MD (8237 feet TVDSS). (9) The sidetrack was drilled from 18-13A off the whipstock set at 9200 ft MD (8260 ft TVDSS) through the dual liner. Top of window 9202 ft.MD (8261 ft.TVDSS) Bottom of window 9211 ft.MD (8265 ft.TVDSS) (10) Baker Hughes INTEQ runs 1 and 2 were used to mill a FasDrill plug and set a retrievable whipstock with KB packer. (11) Baker Hughes INTEQ run 3 was used in a fishing assembly to retieve the whipstock with KB packer. (12) Baker Hughes INTEQ runs 4 and 5 were used to set a whipstock and mill a window. (13) Baker Hughes INTEQ run 9 was used to drill 18-13BPB1 to a TD of 10578 feet MD (8704 ft TVDSS). (14) Baker Hughes INTEQ run 10 was used to set an aluminum billet at 10230 feet MD (8699 ft TVDSS). (15) The USR sub was utilized on run 12 although no data is presented due to data processing issues with the downhole tool.
