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.

An alternate target has been identified that is situated approximately 700' to the northwest of the original target position. The geologic prognosis of the new BHL location predicts commercial LOC that is expected to range between 28' to 30' tvd. The redrill objectives of the 4-34 A redrill will be to section mill an 80' window in the intermediate 7-5/8" casing, lay a cement plug across the section, kickoff and drill a new 6-3/4" hole to the new bottom hole location, run open hole logs, run and cement a 5-1/2" 17# 13CR liner and complete with 3-1/2" x 2-7/8" 13CR tubing. Perforating of the Lower Romeo will be performed prior to the running of the completion. BACKGROUND: DS 4-34 was initially spudded on 9/27/91. The well was kicked off at 500' md/tvd with inclination angle being built to 56~. The 10-3/4" casing was run and cemented without incident at 3513' TVD/3970' MD. The intermediate 9-7/8" hole section was then drilled to casing point at 13618' md. Intermediate 7-5/8" casing was then run and cemented with an MTC cretaceous lead slurry and "G" tail system. The intermediate 7-5/8" was set with emergency slips to reduce potential rathole due to the high inclination of the wellbore and its related sensitivity to shale instability. A 6-3/4" production hole was then drilled to TD in the well at 13,840'MD/8868' TVD. Open hole Icg evalution of the production hole did not indicate producable oil column. A gyroscopic survey was run to confirm the MWD directional coordinates - the results of which validated the MWD. DS 4-34 was then temporarily abandoned by positioning an EZSV at 13543' MD and squeezing 8.5 bbls below- an additional 11 bbls of cement was placed on top of the EZSV. The cement top was tagged at 13035' md and 10,000 # of stringweight was slacked off to confirm cement integrity ( witnessed by AOGCC inspector Doug Amos). The well was then displaced to diesel from 2180' md to surface, an FMC dryhole tree was installed & tested and the 10-3/4" x 7-5/8" annulus was freeze protected with 120 bbls of diesel.

Commissio~ :Anchorage PBU DS 4-34A OPERATIONS SUMMARY CONT'D Note: Excess non-hazardous fluids developed from the well operations and as necessary to control the reserve pit fluid level will be pumped down the 7-5/8" x 10-3/4" annulus. The annulus will be left with a non-freezing fluid during any extended period. The annulus will be sealed with 300 sxs of cement followed by Arctic Pak. b. Minimum distances of wells within 200 ft. of the proposed well are: o L4-31: 293' @ 13227' MD/8848TVD c. The drilling fluid program and surface system will conform to the regulations set forth in 20AAC25.OJ63..o33 ~-~t ],t. doo/c.k,~ ~.~. ck Maximum surface pressure is based on BHP and a full'column of gas to TD (0.10 psi/ft ). e. Based on previous logs on DS#4, no potential productive zones are anticipated above 3500' TVD. f. No potential hazardous levels of H2S are anticipated in this well.
