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. Item 1: Classification of Service Wells: Gas injection, water injection, steam injection, air injection, salt water disposal, water supply for injection, observation, injection for in-situ combustion. Item 5: Indicate which elevation is used as reference (where not otherwise shown) for depth measurements given in other space on this form and in any attachments. Item 16 and 24: If this well is completed for separate production from more than one interval (multiple completion), so state in item 16, and in item 24 show the productin intervals for only the interval reported in item 27. Submit a separate form for each additional interval to be separately produced, showing the data pertinent to such interval. Item 21: Indicate whether from ground level (GL) or other elevation (DF, KB, etc.). Item 23: Attached supplemental records for this well should show the details of any multiple stage cement- ing and the location of the cementing tool. Item 27: Method of Operation: Flowing, Gas Lift, Rod Pump, Hydraulic Pump, Submersible, Water In- jection, Gas Injection, Shut-in, Other-explain.

The abandoned hole should be named the "A-15RDST1L1PB1" (the final "1" is added just in case there are other unplanned sidetracks). All well logs and data associated with the abandoned hole must be identified by the API number 50-733-20105-70. Best wishes on this well.

Our proposed lateral sidetrack will require a new permit to drill. Per you discussions with Tim Billingsley, a new Permit to Drill will be submitted to the AOGCC either today or tomorrow with respect to the lateral sidetrack. The deviated wellbore will be in excess of 1,000 feet from the closest wellbore capable of producing, the K-13RD. Furthermore, common ownerships exist on both sides of the TBU/TBF lease line. Therefore, a spacing exception with respect to the lateral sidetrack is not necessary. A letter to this same effect will follow this email. Regards, Shannon W.

The old 6" wellbore, A-15RD ST1 will not be abandoned and will not be cased off, The Hemlock HB-2 sand formation was found to be deeper than expected and closer to the lease line in A-15RD ST1. The proposed open hole sidetrack will be drilled lower than the original hole and will encounter more footage of good HB-2 porosity. The expected spud date for this A-15RDST1 L 1 is February 28, 2002 so your timely consideration for approval is appreciated. If there are any questions, please contact Dan Williamson at 263-7677 or Tim Billingsley at 263-7659. d£:Y~ Dan Williamson Drilling Manager RECEIVED AOGCC cover letter A-15RDSTl Ll APD.doc FEa 2 8 2002 AlalkaOil & Ga Cool, Commisston A\1QU~ ~) ~)~!Æ~E .:} fÆ~fÆ~~~l ALASKA OIL AND GAS CONSERVAnONCO~SSION ) ~I( / / TONY KNOWLES, GOVERNOR 333 W.

The permit to drill does not exempt you from obtaining additional permits required by law from other governmental agencies, and does not authorize conducting drilling operations until all other required permitting determinations are made. Annular disposal has not been requested as part of the Permit to Drill application for McArthur River Field A-15 RDSTILl. The prior authorization to haul and dispose of liquid drilling waste from Monopod to Grayling is still valid. Blowout prevention equipment (BOPE) must be tested in accordance with 20 AAC 25 035. Sufficient notice (approximately 24 hours) must be given to allow a representative of the Commission to witness a test of BOPE installed prior to drilling new hole. Notice may be given by contacting the Commission petroleum field inspector on the North Slope pager at 659-3607.
