The corrosion inhibitor is engineered to prevent water from entering the annular space and causing external corrosion that could result in a surface casing leak to atmosphere. The attached spreadsheet represents the well name, API and PTD numbers, top of cement depth prior to filling and volumes of corrosion inhibitor used in each conductor. As per previous agreement with the AOGCC, this letter and spreadsheet serve as notification that the treatments took place and meet the requirements of form 10 -404, Report of Sundry Operations.

NA --- Water injection well. Well Y-27 is a WAG well, that was worked over 11/09/1997. Last injection was water on 11/03/2002. Well was shut-in on 06/04/2003 due to a leak in the Bradenhead. A plug was set in the X nipple on 07/07/2004. It has been shut-in since then. The objective is to put this well back on water injection after the Bradenhead has been welded. The X plug was pulled from the X nipple at 2212' and a tubing caliper was run from the tubing tail to the surface (05/09/2006). This caliper information was used to determine where to shoot holes in the tubing, so that the tubing and the IA fluids may be changed out to inhibited water. Then the Bradenhead will be welded. After that is completed, a Tubing Patch will be run and set over the holes in tubing so that well integrity may be established again. Well will be placed back on water injection. Please contact Herry Subekti at 564-5112 (wk) or Jennifer Julian at 564-5663,274-0929 (hm) or 240-8037(cell) with any questions or comments. cc: w/a: Well File . .

The Drilling fluid program will consist of an 8.5 - 9.5 ppg spud mud in the 17- 1/2" hole, a 9.0 - 9.7 ppg water base mud in the 12-1/4" hole and a 8.6 ppg water base mud in the 8-1/2" hole. Drill 17-1/2" hole to 2700' TVD(BKB) and cement 13-3/8" L-80 Buttress casing to surface. Nudge the surface hole 25' to south direction to avoid possible inter- sections with Y-12, Y-19, and Y-20. The closest approach distances after nudge the surface hole are 28 ft from Y-12, 36' from Y-19, and 52' from Y-20. Install blowout prevention equipment consisting of 5000 psi W.P. pipe rams, blind rams, and annular preventer. Maximum possible bottomhole pressure is 3680 psi at 8800' TVD(SS) based on .original reservoir pressure. Maximum possible surface pressure is 3330 psi based on a gas column to surface from 8600' TVD(SS) and an oil column to 8800' TVD(SS). Directional drill 12-1/4" hole to the 9-5/8" casing point above the Sag River Sandstone. Run 9-5/8" 47# L-80 NSCC casing to within 5' of 12-1/4" TD and cement with Class G cement around the 9-5/8" shoe. The annulus will be freeze protected by dry crude. Directional drill 8-1/2" hole to TD. Run 5-1/2" liner from TD to 250' inside 9-5/8" casing shoe and cement using Class G cement. Clean out to 5-1/2" float equipment. Change over to NaC1 completion fluid. Test casing and lap to 3000 psi. Run 9-5/8" 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 with diesel. Displace tubing to diesel. Set and test packer. Shut down rig operations for perforating subsequent to rig release. will be perforated in accordance with normal practices.
