Readings varied from 114° to 128° left of high side (looking downhole). Wellbore deviation is 51.7°. POH. Tattletale (2" long piece of lead solder) mashed against key, but not sheared. The key is shiny on the bottom like it has rubbed in the keyway. The tattletale is not sheared possibly due to the high wellbore deviation. This is the highest wellbore deviation that this anchor has been set in by this TIW representative. Discuss options with Slope CTD personnel. Given the facts that (a) the well is highly deviated reducing ability to set down weight, (b) the positive markings on the stinger indicating entry into the anchor, and (c) that thirteen readings fell between 111° and 128° left of high side, the orientation verification is thought to be valid. Rig down SWS Ut #2158. Note: Estimated Daily Costs include the cost of the TIW Whipstock and personnel time to run it, although these costs will be incurred after CTD rig up.

A schematic diagram of the proposed sidetrack completion is attached. E-15a is a horizontal sidetrack with both perforations and slotted liner in the horizontal section to be abandoned. E-15b will be completed with a fully cemented and perforated 2 7/8" liner. The following summarizes the procedure required to prepare E-15a for sidetracking and is submitted as an attachment to Form 10-403. 1. A tubing integrity test was successfully performed on 3/29/99. 2. Tubing and liner will be drifted with a 3.65" OD drift. 3. A Cast Iron Bridge Plug will be set at 10,500', above existing perfs. The well will be pressure tested to 1500 psi against this bridge plug. 4. A 4.5" whipstock will be set on E-Line at 10,424'. 5. Window milling through the 4 ½" liner will be done by drilling coil after approval of the Form 10-40t. Prep work is expected to begin by May 15, 1999 and milling/drilling is expected to begin about May 20, 1999. ?¢ Ted Stagg CT Drilling Engineer cc: Well File Petrotechnical Data Center ~---- STATE OF ALASKA --.

The entire existing producing interval ofE-15a is essentially horizontal. There is no interest, from a reservoir management viewpoint, in cementing across this long horizontal interval prior to drilling the new sidetrack. Our goals can be met by setting a bridge plug above the existing perfs. The plan I have submitted calls for setting a cast iron bridge plug above the existing perfs and slotted liner and pressure testing this plug. The next step would be to set the whipstock anchor, which is a solid plug itself, just above the CIBP. This would provide two permanent plugs isolating the original horizontal completion from the window for the new sidetrack. The whipstock would then be stung into the whipstock anchor. After milling and drilling, the sidetrack completion will be a fully cemented 2 7/8" liner with a cement volume large enough to place 200 ft of cement above the window. While this procedure differs a bit from what is described in the regs I believe it makes both technical and economic sense for this type of sidetrack. To add additional cementing to this horizontal well prep would add significant cost with no benefit that I can see. Please call if further info or discussion is needed.

The rig was still coming out of the hole when I arrived. The test once staded went very well with all components functioning properly and holding their pressure test. The test lasted 2.5 hours with no failures observed. I found the rig to be in very good condition. Mark Egholm (Doyon Toolpusher) showed foresight in scheduling this test as it was not due for two more days. The rig was standing by for cement to cure and this test was performed as to give them a solid week of drilling without interuption. Summary: I witnessed the weekly BOP test on Doyon rig #14. Test time 2.5 hours. No failures.

The permit to redrill 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 (BOPE) must be tested in accordance with 20 AAC 25 035. Sufficient notice (approximately 24 hours) must be given to allow a representative of the Commission to witness a test of BOPE installed prior to drilling new hole.

RU slickline unit. WLIH and install a plug in the 4-1/2" XN nipple in the + , tailpipe at _9409 md'. WLOH. WLIH and punch circulating holes in the 7" tubing at _+9270' md in the middle of the first full joint above the packer. WLOH and RD slickline. Freeze protect tubing and annulus to 2000' md/tvd and set a BPV. Move in drilling rig. Pull BPV. Circulate diesel freeze protection cap from well and recover for future use. Install a BPV and tree test plug. Remove the production tree. Install BOP's and test to 5000 psi. Remove the test plug and BPV. Shear SBR. Pull and lay down the 7'-- tubing. Recover slickstick/anchor. Mill and retrieve packer. Displace well to milling fluid. Cut a 50' section in the 7'__~' casing starting from about +_IO.;~O0'MD. RIH with 2-7/8", 8.7#, DSS tubing and lay a cement plug from PBTD across and above the section up to -+9963' md. This plug will serve as both the abandonment plug and the kickoff plug. Squeeze away approximately 5 bbl cement to abandon perforations leaving the top opf cement before drilling out at -+10,100' md which is 200' above top of window. Run in with an 4-3/4" steerable drilling assembly and a 6" bit with gamma ray/directional MWD and dress the cement to 5' below the section top. Kickoff and if necessary displace well to a clean FLO-PRO system. Continue to directionally drill to TD at +_11,688' md which should yield _+644' of horizontal section (see attached directional plan). Make a conditioning trip with a 6" hole-opener for the open hole section and with a 9-5/8" casing scraper spaced to clean the casing. Install a 4-1/2". 17_.6#. L-80. NSCT solid liner x 4-1/2". L-80 slotted liner with 4- 1/2" X 9-5/8" packer/hanger. Space packer / hanger to be set at _+9,2_75' md. Cement the liner in place with the total cement volume based upon 50 % open-hole enlargement plus the 80' shoe volume, 150' lap volume and 150' excess on top of the liner with drillpipe in the hole. Set hanger, inflate CTC packer. Re-test BOP's as needed. RIH and cleanout Displace well to seawater. Run the 4-1/2" L-80 completion string assembly utilizing as much used 4-1/2" tubing as possible. Space out and circulate with corrosion inhibitor. Install a BPV and test plug. Remove BOP's. Install and test the production tree to 5000 psi. Pull tree test plug and BPV. Set packer. Test the tubing x casing annulus to 3500 psi for 30 minutes. Shear RP valve in the upper GLM and freeze protect the well. Set a BPV. Release rig. Complete appropriate documentation and hand-over to Production.
