Terrie Hubble, 564-4628 Well Number P r i N./ A v I N brining engineer: Amanda Rebol, 564-5543 INSTRUCTIONS GENERAL: 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. IreM 1a: Classification of Service Wells: Gas Injection, Water Injection, Water-Aftemating-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. IreM 4b: TPI (Top of Producing Interval). IreM 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). IreM 20: Report true vertical thickness of permafoost in Box 20. Provide MD and TVD for the top and base of permafrost in Box 28. ITEM 22: Attached supplemental records for this well should show the details of any multiple stage cementing and the location of the cementing tool. IreM 23: 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). IreM 28: Method of Operation: Flowing, Gas Lift, Rod Pump, Hydraulic Pump, Submersible, Water Injection, Gas Injection, Shut-In, or Other (explain). IreM 27: 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.

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.

The target sands in the Schrader are expected to be normally pressured at 8.6-8.7 ppg EMW. II. Hydrates and Shallow gas A. Gas Hydrates are expected at V-pad from the SV5 thru the SV1 sands below the base of the Permafrost. Setting surface casing below deepest SVi 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. Lost circulation and breathing are not anticipated in V-207. If lost circulation occurs, follow the LCM decision tree. IV.

V. Hydrogen Sulfide V Pad is not designated as an H2S site, however Standard Operating Procedures for H2S precautions should be followed at all times. V Pad gas lift wells are expected to have H2S levels in the 10 to 300 ppm range as a result of using PBU gas lift gas. Recent H2S data from the pad is as follows: Adjacent producers at Surface: Adjacent producers at TD: V-122 30 ppm V-205 10 ppm V-117 120 ppm Vl. Faults A. Two faults are expected to be crossed by V-207. The V-Pad fault will be penetrated at high angle, minimizing contact with the fault zone. The second fault is in the M-sand and is low throw. No losses are expected to be associated with either of these faults.
