This well was originally completed 4/23/92 and there have been no workovers performed to date on the original wellbore. The well was frac'd 7/93. Well has been shut in since mid 1996 due to low oil rate/ high watercut and TxlA communication. In July 1995 a leak detection log indicated multiple tubing leaks; however, no tubing caliper surveys have ever been performed. A tubing tail plug was set at 13,510 SLM on 12/3/05. Several pressure tests have been performed to evaluate structural integrity since shut in. Passed tests include PPPOT-T and IC (12/10/05) and MITOA to 3,000 psi (1/11/06). The CMIT x ./ IA failed as expected (1/11/06). The plan is to plug and abandon the existing perforations (14,090' - 14,315' md) with service coil, bringing cement up to the production packer at 13,461' md. The 4-%" tubing will be j~ at 4,000' md. Upon arrival, the rig will pull the 4-W' tubing, control line and bands, and a ~§W'log run to evaluate a potential down squeeze cement job. An EZSV will be set at 3,275' mõ;'ánd the 7 -%" casing will be cut above the down squeeze cement via mechanical cutter. The remaining casing will be milled as needed to obtain a casing stub at 3,225' md which is approximately 200' md below the surface casing shoe. A 17.0 ppg cement kick off plug will be placed from the plug at 3,275' md to 2,822' md which is 200' i~ surface casing. Once the cement has gained sufficient compressive strength, the new Z~19M hole will be drilled to a secondary TSGR target. ../ The planned well then has a 400' productioMl1jection interval in the Zone 4 sands. A solid 4- %" liner will be cemented in place throughout the production/injection interval. Pre-RiQ Operations: 1. MIRU Schlumberger slickline. Pull TTP@13,510'SLM.Takestatic BHP a~ernp. 2.

Fluid pack well with sea water. (Note IA still in communications with tubing via leak at packer? GLM dummied off with a shear out valve in stag 5). Tag small amount of fill at 14139' CTD. Washed thru. Rig up BJ and hold safety meeting. Acidized the perforated interval 14090' to 14140' with 458 bbls 5% HCL while reciprocating nozzle across perforations. Displace acid from coil with sea water (0.2% surf). Over flush with 50 bbls. Release BJ. Throught the entire job WHP/IAP tracked pound for pound. Well went on vacumn after displacing acid. Two attempts were made to "pop" shear- out valve in station# 5. Both tries unsuccessful because we were unable to get any pressure differential. Start pulling out of hole. Freeze protect coil and finish out of hole. Close in well remove fusible cap. Notify MOC and Pad Operator that well remains shut in for S-line work in AM.

The permit to drill 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 (BO?E) must be tested in accordance with 20 AAC 25.035. Sufficient notice (approximately 24 hours) of the BOPE test performed before drilling below the surface casing shoe must be given so that a representative of the Comm- ission may witness the test. Notice may be given by contacting the commission petroleum field inspector on the North Slope pager at 659-3607.

The Drilling fluid program will consist of an 9.5 - 10.2 ppg spud mud in the 13- 1/2" hole, a 9.5 - 10.5 ppg water base mud in the 9-7/8" hole and an 8.9 ppg water based mud in the 6-3/4" hole. Drill 13-1/2" hole to 3000'. Run and cement 10-3/4", 45.5 #, NT-80LHE Buttress casing to surface. Install blowout prevention equipment consisting of 5000 psi W.P. pipe rams, blind rams, and annular preventer. Maximum possible bottomhole pressure is 4390 psi at 8800' TVDss based on original reservoir pressure. Maximum possible surface pressure is 3330 psi based on a gas column to surface from 8600' TVDss and an oil column to 8800' TVDss. A formation leak-off test will be performed 10' below the 10-3/4" shoe. Directionally drill 9-7/8" hole to the 7-5/8" casing point above the top of Sag River Sandstone. Run a 7-5/8" casing string of 29.7# NT-95HS NSCC to within 10' of 9-7/8" TD and cement with Class G cement around the 7-5/8" shoe. The annulus will be freeze protected by dry crude. Directionally drill the 6-3/4" hole to TD. Run 5-1/2" liner from TD to 250' inside 7-5/8" casing shoe and cement using Class G cement. Clean out to 5-1/2" float equipment. Change over to NaCI completion fluid. Test casing and lap to 3500 psi. Run 7-5/8" production packer on tubing. Set packer 50' above top of liner. A subsurface safety valve with dual control lines will be placed 100' below base of permafrost. Install and test Xmas tree. Displace tubing to diesel. Set and test packer. The well will be perforated after the rig has been released. Fluids incidental to the drilling of a well will be pumped down the 7-5/8" x 10- 3/4" annulus of the well.
