IrEM 1a: 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. IrEM 4b: TPI (Top of Producing Interval). IrEM 8: The Kelly Bushing elevation in feet above mean low low water. Use same as reference for depth measurements given in other spaces on this fomn and in any attachments. IrEM 13: The API number reported to AOGCC must be 14 digits (ex: 50-029-20123-00-00). IrEM 20: True vertical thickness. IrEM 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 fomn for each additional interval to be separately produced, showing the data pertinent to such interval). IrEM 26: Method of Operation: Flowing, Gas Lift, Rod Pump, Hydraulic Pump, Submersible, Water Injection, Gas Injection, Shut-In, or Other (explain). IrEM 27: If no cores taken, indicate "None".

Obp To: Winton Aubert Petroleum Engineer Alaska Oil & Gas Conservation Commission From: Garret Staudinger CTD Engineer Date: September 5, 2006 Re: Prep Prudhoe A-42 for CTD sidetrack Sundry approval is requested to prepare A-42 for a sidetrack. A-42 is a peripheral, pre-produced injector well drilled in 1995. It was placed in a ZNla target area bounded east and west by parallel faults. It produced 567 mbo through March 2006, when it was shut for low production. With no wellwork options available to enhance production, a sidetrack to a new area is planned. The sidetrack, A-42A, is scheduled to be drilled by Nordic 1 on or about November 20.2006. The plan calls for setting a setting a 4-1/2" Baker Monobore whipstock in the 4-1/2" slotted liner, and down squeezing 15.8 ppg / cement past it. A schematic diagram of the proposed sidetrack is attached for reference.

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. The blowout prevention equipment (BOPE) must be tested in accordance with 20 AAC 25.035; and the mechanical integrity (MI) of the injection wells must be demonstrated under 20 AAC 25.412 and 20 25.030(g)(3). Sufficient notice (approximately 24 hours) of the MI test before operation, and of the BOPE test performed before drilling below the surface casing shoe, must be given so that a representative of the Commission may witness the tests. Notice may be given by contacting-the Commission petroleum field inspector on the North Slope pager at David W. Jo~_~ Chairman · .
