Drilling & Wells Coiled Tubing Drilling Team Well E-35 is scheduled for a through tubing sidetrack to be drilled with coiled tubing. The following summarizes the procedure required to prep E-35 for drilling and is submitted as an attachment to Form 10-403. A schematic diagram of this proposed completion is attached. 1. Tree wing & master valves will be tested. :2. Using slickline, tubing will be drifted, a caliper run on the liner & gas lift mandrels will be dummied off. 3. Inner Annulus will be liquid packed and pressure tested. 4. Using coil tubing a 4-1/2" through tubing whipstock will be run & set in the 4- 1/2" slotted liner at approximately 9,190'md (8,735' TVDss). 5. Service coil may then mill a 3.8" window out of the 4-1/2" slotted liner. Slickline and service coil prep work is expected to commence June 21. Coil tubing drilling operations, as detailed below will commence June 28, 2001. 1. A 3-~A'' sidetrack, -1786' long will be drilled out of 4-1/2" slotted liner and into Zones 2B and 2C. 2. The sidetrack will be completed with a 3 Y2" x 2-7/8", solid, cemented & perforated liner. ohn Cubbon CT Drilling Engineer Tel' 564-4158 Fax' 564-551 0 Cell' 240-8040 cubbonjr@bp.com Well File Petrotechnical Data Center Terrie Hubble 'tREE: 4-1/16"-5M CIW WELLHEAD: 13 5/8" - 5M FMC ACTUATOR: BAKER E-35a Proposed Completion KB.

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 (BOPE) 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 Commission may witness the test. Notice may be given by contacting the Commission petroleum field inspector on the North Slope pager at 659-3607.

A formation leak-off test will be performed 10' below the 10-3/4" shoe to a minimum of 12.0 ppg EMW. o Directionally drill 9-7/8" hole & building to horizontal target in Sag River @ 9,320' MD/8,813' TVD. TIH w/9-7/8" hole opener if needed. Run 7-5/8" 29.7# L-80 NSCC casing and cement with Class G cement to 1000' MD above the top of the hydrocarbon- bearing sand @ 7,229' MD. The annulus will be freeze protected with dry crude if not annular injecting. Test casing to 3,500 psi. o TIH w/6-3/4" BHA. PU 3-1/2" DP. Drill 10' of new hole and displace to Xanvis KCL mud system. Directionally drill the 6-3/4" horizontal hole to TD. RIH w/ 6-3/4" holeopener and 7-5/8" scraper spaced out to near the bottom of the 7-5/8" casing. Circulate horizontal section clean. . Run 4-1/2" 12.6# L-80 NSCT slotted liner with a horizontal liner top packer. The liner will be set at TD and lapped +150' inside 7-5/8" casing shoe. Release from packer and displace Xanvis mud with filtered seawater spotting lithium hypochlorite breaker in liner. 8. POH LDDP. , Run 4-1/2" L-80 tubing with SSSV, GLM's, and 7-5/8" x 4-1/2" packer assembly. Displace well with filtered seawater and corrosion inhibitor. Set packer and test tubing annulus w/3,500 psi. 10. Set BPV. ND BOPE. 11. Freeze protect well to 2200' TVD through shear valve in top GLM station. Release rig. Drilling Hazards · One hydrocarbon-bearing zone is found above the Sag River formation @ 7,229' md based on E Pad logs. The zone is expected to be normal pressure with a relatively low permeable sand. · A minimum of 9.5 ppg mud weight will be used to drill the Cretaceous injection interval. This will allow a 100 psi trip margin over the expected 9.0 ppg EMW @ 4000' sstvd. · A range of mud weights from 9.0 ppg to 9.2 ppg will be used to drill the Sag River interval.
