Oommissio~ Anchorage To: Blair Wondzell Sr. Petroleum Engineer Alaska Oil & Gas Conservation Commission From: Ted Stagg CTD Engineer Date: Sept. 26, 2000 Re: Well 18-27c Well 18-27a is scheduled for a through tubing sidetrack with the Schl./Nordic coil drilling rig. The sidetrack, 18- 27c, will kick off from a window milled from a mechanical whipstock to be set in the Zone I interval of 18-27a. The 18-27c target is lower Zone I to the east of 18-27a. The following describes work planned to prep 18-27a for sidetracking and is submitted as an attachment to Form 10-403. A schematic diagram of the proposed sidetrack completion is attached for reference. 1. GLM's have been dummied off. The IA will be loaded and pressure tested to 2500 psi. 2. A dummy whipstock drift will be run on service coil. 3. Service coil will set a whipstock anchor-bridge plug at 12,350' to isolate from existing Zone 1 perfs and to provide a whipstock anchor. The anchor-plug will be tested to 2500 psi. 4. Service coil will run a memory inclinometer that will sting into the whipstock anchor to confirm orientation of the whipstock tray orienting lug. 5. The whipstock tray will be installed by the drilling coil rig. Service coil is scheduled to set the whipstock anchor-plug on Sept. 30 if Sundry approval is received by that time. Drilling coil will move onto the well on Monday Oct. 2 if technical approvals and the Permit to Drill are received.

The permit to redrill 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. 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 xvitness a test of BOPE installed prior to drilling new hole.
