According to the letter, graphical files can be submitted in lieu of sepias or bluelines (see attached).We also understand there was an agreement with the Commission to limit the submission of large paper log copies greater than 2 inches. Internally, BP is still sending paper logs less than 3 inches thick. We checked and the V-229 MDT log is about 5 inches thick. Please clarify if either of these guidelines still apply and if you would still want the V-229 MDT log in paper format.

This direction and inclination was projected from the final survey point to TD, which resulted in the following bottom-hole location. Measured Depth: 6390 feet True Vertical Depth: 4892.76 feet Formation Evaluation 12-1/4 inch Surface Section The surface section was drilled from 130 feet to 3335 feet MD in three runs. A motor was used for directional control during the runs. There was no MWD during the first run. Gamma Ray was delivered in real-time and recorded mode for the second and third run. After reached TD,9 5/8 inch casing was run.The final measured bottom-hole temperature was 80.00 degrees Fahrenheit. 8-3/4 inch Production Section: The production hole section of the well was drilled from 3335 feet to 6390 feet MD in one run. A motor was used for directional control during the run.Resistivity, Gamma Ray,APWD,Density and Porosity data were supplied in real-time and from memory once the tools were retrieved. The final measured bottom- hole temperature was 107.6 degrees Fahrenheit.

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. 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.

Maximum reservoir pressures anticipated: Interval Psi (EMW) TVDss (ft) MD (ft) Schrader Bluff 2144 (8.6) 4796' 6400' Sands II. Hydrates and Shallow gas: A. Rig should expect to encounter gas hydrates in the SV sands below the Permafrost base. Use standard operating procedures for hydrates, if encountered. Set surface casing below sand hydrate zone to isolate gas bearing intervals behind cemented pipe in surface hole from intermediate hole section. III. Running Gravels: A. Unconsolidated sand, gravel, &cobbles and thawing permafrost could impede well angle build and casing running through permafrost. Keep moderate to low build angles until out of permafrost section. Keep flow rates low. Hazards include cobbles/boulders, running gravels, wood, lost circulation and tight hole problems while drilling and running casing. See Pad data sheet for details. IV. Broaching: A. Surface broaching in nearby wells has been an issue on past V-pad wells. Drill out the conductor with high viscosity spud mud. Do not drill out the conductor with water. While drilling surface hole, watch for losses and monitor the nearby well houses for flow V. Lost Circulation: A. Drilling mud losses up to 2107 bbl have been encountered while drilling surface hole on V-pad. If mud losses occur, reference standard operating procedures, including running LCM and increasing mud viscosity. VI.

What size ramsNBRs are planned for the first BOP test? You don't mention changing rams out for running the 7" casing. Good job on the AOR.. but on some of the cement tops on Kuparuk completions it would be better to state TOC as ND depth also so I know the Schader is isolated.
