Well A-31 ai Prep for CT Sidetrack Well A-31 is scheduled for a through tubing sidetrack to be drilled with coiled tubing. The following summarizes the procedure required to prepare A-31 for sidetracking and is submitted as an attachment to Form 10-403. A schematic diagram of this proposed completion is attached. 1. A Mechanical Integrity Test will be performed with AOGCC witness. 2. A Schmoo-B-Gone treatment was performed on 5/7/99. 3. A Kinley caliper was run on 5/10/99. 4. A whipstock drift run was done on 5/9/99. 5. E-Line will be used to set a mechanical whipstock in the 7" liner at approx. 9,584'. 6. After approval of the Permit to Drill, drilling coil will be used to pump approx 25 bbls cement to abandon the existing Sag R and Ivishak perfs. Abandonment cement will be pressure tested to 2200 psi with AOGCC witness prior to milling the window with drilling coil. 7. The 2 7/8" sidetrack liner will be cemented to at least 200 ft above the window to provide additional isolation. Steps 5, setting the whipstock, is scheduled for June 21, 1999. Step 6, squeezing cement, is scheduled to be performed by the drilling coil on July 7, 1999, pending approval of the Permit to Drill. These dates are based on our estimate for completion of summer rig maintenance currently in progress.

Dear Mr. Reiley: Enclosed is the approved application for permit to drill the above referenced well. If coring is conducted, a brief description of each core and a one cubic inch size chip from each foot of recovered core is required. Samples of drill cuttings and a mud log are not required. A continuous directional survey is required as per 20 AAC 25.050(b)(5). If available, a tape containing the ~.or digitized log information shall be submitted on all logs : copying except experimental logs, velocity surveys and dipmeter surveys. Many rivers in Alaska and their drainage systems have been classified as important for the spawning or migration of anadromous fish. Operations in these areas are subject to AS 16.05.870 and the regulations promulgated thereunder (Title 5, Alaska Administrative Code). Prior to commencing operations you may be contacted by the'Habitat Coordinator's Office, Department of Fish and Game.
