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 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.

The permit is for a new wellbore segment of existing well PBU L -203, Permit No. 209108, API No. 50- 029 - 2341600 -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 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 Commission to witness any required test, contact the Commission's petroleum field inspector at (907) 659 -3607 (pager). Sincerely, Cathy r.

Based upon calculations below, BOP equipment will be tested to 3,500 psi. Due to surface pressures not exceeding 3,000psi it will not be necessary to have two sets of pipe rams installed at all times. BOP regular test frequency will be 14 days, with a function test every 7 days. Diverter, BOPE and drilling fluid system schematics on file with the AOGCC. Variance Request • To avoid the risk of plugging the flow line with large rocks and wood encountered while drilling surface hole, it is requested to drill without a flow paddle for the first portion of the surface hole. After drilling past the larger rocks and wood sections, the flow paddle will be put back in the flow line. • To mitigate any risk involved with no flow paddle, the following steps will be taken while the flow paddle is removed from the flow line. Ensure PVT alarms are used and the pit levels are accurately monitored for any pit gain. Visually look down the riser during connections to ensure the well is not flowing. Surface Hole A diverter will be nippled up and function tested prior to drilling surface hole Intermediate Section • Maximum anticipated BHP: 2,160 psi — Schrader OBb (9.3 ppg @ 4,470' TVDss) • Maximum surface pressure: 1,713 psi — Based on a full column of gas @ 0.10 psi /ft • Planned BOP test pressure: 3,500 psi /250 psi Rams 2,500 psi /250 psi Annular • 10 -3/4" Casing Test: 3,500 psi • Integrity Test — 9 -7/8" hole: LOT • Kick Tolerance: 53 bbls with a minimum 11.2 ppg EMW LOT, 9.4 ppg MW Production Section • Maximum anticipated BHP: 2,160 psi — Schrader OBb (9.3 ppg @ 4,470' TVDss) • Maximum surface pressure: 1,713 psi — Based on a full column of gas CP 0.10 psi /ft • Planned BOP test pressure: 3,500 psi /250 psi Rams 2,500 psi /250 psi Annular • 7 -5/8" Casing Test: 3,500 psi • Integrity Test — 6 -3/4" hole: LOT for L -203 OBd production interval only • Kick Tolerance: Infinite at OBd, OBc, OBa, and Nb with a minimum 10.1 ppg EMW LOT • Planned completion fluid: 9.6 ppg SF OBM in Laterals, 9.6 ppg Brine, 6.8 ppg diesel in mother bore Disposal • No annular injection in this well. • Cuttings Handling: Cuttings generated from drilling operations will be hauled to grind and inject at DS- 04.

The target sands in the Schrader are potentially over - pressured do to nearby water injection from L -2151 and L -216i. A maximum pressure of 9.3 ppg EMW can be expected in the N and 0 Sands. II. Hydrates and Shallow gas A. Gas Hydrates are expected at L -pad from the SV5 thru the SV1 sands below the base of the Permafrost. Setting surface casing below deepest SV1 sand hydrate zone will isolate gas bearing intervals from the intermediate section. If hydrates are encountered, recommended practices and precautions for drilling hydrates should be followed in the surface hole. III. Lost Circulation /Breathing A. There is a low risk of lost circulation and breathing anticipated in L -203. If lost circulation occurs, follow the LCM decision tree. IV.

A LOT will only be performed for the first OBd lateral, not the OBc, OBa, or Nb. V. Hydrogen Sulfide Standard Operating Procedures for H precautions should be followed at all times. L Pad gas lift wells are expected to have H levels in the 10 to 250 ppm range as a result of using PBU gas lift gas. Recent H data from the pad is as follows: Adjacent producers at Surface: Adjacent producers at TD: L -201 20 ppm L -202 10 ppm L -202 10 ppm L -250L1 20 ppm VI. Faults A. Two faults are expected to be crossed by V -207, with another two possible fault crossings. The first 3 faults are expected in the intermediate section, and no losses are expected to be associated with these faults.
