To: Date: From: Subject: State of Alaska January 6, 1997 Matt Scheuring Doyon 9 Operations Drilling Engineer 18-08A P&A Operations Summary: 18-08 History 18-08 was originally drilled in April 1986. It is a vertical well completion in Zone lB and lA with 38 feet of perforations. Initial production was 2000 BOPD. In January 1987, half strength mud acid was pumped to improve productivity. Shortly afterwards GOR began to rise. A PITS log in October 1987 showed a channel up to the GOC. By March 1988, the well reached an uncompetitive GOR. April 1988 brought a GSO squeeze behind the pipe, sealing off the channel. The well returned to production at 1500 BOPD and solu- tion GOR and after a few months GOR began to slowly rise. The well reached MGOR in 1990 and has been cycle produced since then. YTD, the well has been on-line 67% of the time, averaging 720 BOPD with a GOR of 18,600. Cumulative oil production is 3,560 MBO. Doyon Rig 9 may move to DS 18-08A on/about January 15, 1998 following the completion of Well 18-06A. The drilling objective of well 18-08A is to mill through 7-5/8" casing via whipstock into Zone 4, and direction- ally drill this sidetrack well down to a single 1,250' horizontal target in the remaining L. Romeo reserves trapped along the down-thrown side of a normal fault. Pre-Rig Operations: The objective of the pre-rig work is to ascertain the condition of the 3 ¥~" tubing and 7 5/8" casing presently in the hole; P & A all open perforations; chemically cut the 3 1,~,, tubing; test the 7 5/8" pack off. 1. Notify AOGCC of initiation prior to commencing any P&A operations. 2. NU on Well. Bullhead seawater down tubing to kill well and verify injectivity. Report injectivity to ODE. 3. Make GR/JB run on 3~" tubing. 4. Pressure test 9 5/8" annulus to 3000 psi for 30 min to check for casing integrity and tubing integrity to packer. If pressure test fails, set plug in tubing and pressure test to 2000 psi for 30 min. Call ODE if there are any problems. 5. Bullhead 88 sks. (18 bbls.) of class G, 15.8 ppg cement down tubing, and displace to place TOC @ 100' above top perf. Rig operations will set a bridge plug @ 9556' MD to form additional barrier. 6. Pressure test cement P&A. 7. Chemically cut tubing between 9600' and 9887' MD. 8. Circulate and freeze protect tubing. 9. Test packoffs on tubing and 7 5/8" annulus, and carefully cycle Iockdown screws. 10. Set BPV. 11. Clear location, dig out cellar, remove electrical lines, remove well house. Rig Operations 1. MIRU 2. Pull BPV 3. Circulate out freeze protection and kill well with seawater. 4. ND tree. NU BOP. 5. Test BOP 6. Change packoff if failed in Pre-rig 7. Pull tbg. 8.

Dear Mr. Oostermeyer: 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 governmemtal agencies prior to commencing operations at the well site. To aid us in scheduling field work, please notify this office 24 hours prior to commencing 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, l,~ere 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.

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 and operationally tested each trip. After reaching TD, logs will be run across selected intervals. The well will be completed as a producer using a workover rig at a later date. A 3-1/2" tubing string and packer will be run and set above the Sadlerochit. A downhole safety valve will be installed and tested upon completion of the job. Selected intervals will be perforated in the Sadlerochit formation and reported on subsequent reports. Reserve pit fluids will be disposed of down the 7-5/8" x 10-3/4" annulus of this well. The 7-5/8" x 10-3/4" annulus will be left with a non-freezing fluid during any interruption in the disposal process. Upon completion of the disposal process, the annulus will be sealed with 200 sx of cement followed by Arctic Pack. 23.
