PROCEDURE To prepare for the 9-31 redrill, the following actions will need to be taken prior to the rig move: 1. Notify an AOGCC representative prior to commencing plug-back operations. 2. Run in with coil tubing while circulating seawater. Lay a cement plug starting from PBTD. Squeeze down and leave the top of cement at least 100' above the top perforation but below the packer. Therefore, the top of cement should be somewhere between 8850' and 8642' MD. 3. With an AOGCC representative on location to witness the operation, run in with slickline and confirm that top of cement is at least 100' above the top perforation. 3a. If the cement is tagged more than 100' below the tubing tail, set a plug in the tubing tail to prevent future fluid swap-out when laying a kick-off plug. 4. Cut the tubing above the packer at _+8600' MD. 5. Circulate the well over to seawater and freeze protect well with diesel to 2000'MD. 6. Bleed any pressure from the tubing, inner annulus and outer annulus to zero. 7. Install a back-pressure valve. Remove the well house and flowlines. Level the pad and dig out the cellar. Prepare the pad for arrival of the rig.

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 digitized log information shall be submitted on all logs for 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. Pollution of any waters of the State is prohibited by AS 46, Chapter 3, Article 7 and the regulations promulgated thereunder (Title 18, Alaska Administrative Code, Chapter 70) and by the Federal Water Pollution Control Act, as amended. Prior to commencing operations you may be contacted by a representative of the Department of Environmental Conservation. }4r. T. L. Fithia~ Prudhoe Bay Unit DS 9-31 -2- July 18, 1985 To aid us in scheduling field work, please notify this office 24 hours prior to comm_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. !qhere 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. In the event of suspension or abandonment, please give this office adequate advance notification so that we may have a witness present.

Describe proposed program: ARCO Alaska, Inc., proposes to directionally drill this Sadlerochit development well to 9682'MD (9166'TVD). A 20", 2000 psi annular diverter will be installed and operationally tested prior to spud. The 13-5/8", 5000 psi, RSRRA BOPE stack will be installed and tested (rams 5000 psi, annular 3000 psi) upon installation, weekly and operationally tested each trip. After reaching TD, logs will be run across selected intervals. The well will be completed using a workover rig at a later date. A tapered string of 7", 26#, L-80 and 5-1/2", 17#, L-80 tubing will be run and set above the Sadlerochit. A downhole safety valve will be installed and tested upon completion of the job. Non-freezing fluids will be left in all uncemented annuli within the permafrost interval. Selected intervals will be perforated in the Sadlerochit formation and reported on subsequent reports. Reserve pit fluids will be disposed of down the 9-5/8" x 13-3/8" annulus of this well. The 9-5/8" x 13-3/8" annulus will be left with a non-freezing fluid during any interruption in the disposal process. Upon completion of the disposal process, the annulus (see attached sheet) 23.1herebycertify~andcorrecttothebest ofmyknowledge. ..
