The sidetrack, S-20ai, will kick off from a window milled in the Sag R after cement squeezing all existing perfs. The S-20ai target is Zone 2 and Zone 4. Following initial Zone 2 MIST injection, the well will be plugged back to the upper portion of Zone 4B to provide injection support. The following describes work planned to prep for sidetracking and is submitted as an attachment to Form 10-403. A schematic diagram of the proposed sidetrack is attached for reference. 1. Tubing and liner have been drifted to 3.625". 12/21/00 2. Ran Kinley calliper through tubing and liner. 12/20/00 3. Master valve, wing valve and tree successfully tested to 5000psi. 2/20/01 4. Tubing integrity will be verified by MIT 2/01. 5. E-Line will set a mechanical whipstock at approx. 9,155' in the 7" liner. 6. Service coil will squeeze approx. 20 bbls cement past the whipstock to shut off all existing perfs. E-Line is scheduled to set the whipstock and squeeze on Mar 27, 2001. Drilling coil is scheduled to move onto the well for drilling on Apr. 5, 2001. M.S. Endacott CTD Drilling Engineer CC: Well File TREE ~ 4" CIW WELLHEAD= 13-3/8" McEV ACTUATOR= AXELSON KB.

The wells were open to an atmospheric tank to determine fluid production (there was none), and monitored through a gas meter to determine gas production rates. The inspector recommended "no-flow" status for the wells listed below.

Under the authority of Conservation Order 145, Rule 5 (amended by CO 333), these wells are not required to have a fail safe automatic SSSV. However, the surface safety valve and pilot must be maintained in good working condition, and if for any reason the wells again become capable of unassisted flow of hydrocarbons, the subsurface safety valves must be reinstalled and maintained in good working condition.

The drilling contractor was in the process of nippling up the BOP. Tuesday, August 12, 1986: The test commenced at 12:00 midnight and was concluded at 2 15 a.m. There was one failure of the packing on the (9-5/8xi3-3/8) Bradenhead bolts which were tightened up and tested satisfactorily. I filled out an AOGCC BOP inspection report which is attached. In summary, I witnessed the BOP test on SAPC Pad S-20 well, Prudhoe Oil Pool, Nabors Rig 28E.

Dear Mr. Allan: Enclosed is the approved application for permit to drill the above referenced well. The permit to drill does not indemnify you from the probable need to obtain additional permits required by law from other governmental agencies prior to commencing operations at the well site. To aid us in scheduling field work, please notify this office 24 hours prior to co~encing installation of the blowout prevention equipment so that a representative of the Commission may be present to witness testing of the equipment before the surface casing shoe is drilled. ~Yhere a diverter system is required, please also notify this office 24 hours prior to commencing equipment installation so that the Commission may witness testing before drilling below the shoe of the conductor pipe.
