The conversion of this well to water injection is part of a proposed MI expansion project for Drill Sites 4 and 11. As an injector, DS 4-49 will be eastern most of three guard wells which will act to contain MI and prevent its migration up into the gas cap. Reserve benefits will be realized from both waterflood and MI flood processes. Scope of Work In order to convert to water injection service, DS 4-49 will be twinned with existing injection well DS 4-11. Wellwork associated with this conversion will include dummying off the GLV's, circulating the backside with water and a diesel cap and running an MIT. Perforations in the lower Victor will be added and the well put on injection. Current perforations in the Lower Romeo will be left open in order to give additional waterflood support in the area. Diagnostic logs will be run as needed to verify injection conformance. If you have any questions concerning this Sundry Application, please don't hesitate to call me at 564-5735 or E-mail me at babcockdr@bp.com.

I arrived at the rig at 1:00 PM and the test began at 1:30 PM. As the attached AOGCC BOPE Test Report shows~there were 8 failures. There were 2 flange leaks, 4 valves leaked in the choke manifold, a H2S sensor failed at the shale shaker and the annular preventer element leaked. At 6:00 PM the crew began changing out the annular preventer element and I stoodby. The ARCO grease crew came by and serviced all the~valves on the choke manifold, kill line and choke line. At 11 '30 PM the crew began testing and we concluded the test at 2:00 AM. The location was clean and there was good access to all areas of the rig. The rig was clean and ali other equipment seemed to be in good working order. While standingby for tes~t ! spoke with Nick Scales, SSD rig foreman, conceming the cement job on the surface casing. Nick said he pumped 1026 bbls. of 12.21b/gal with _9 pounds of Borax per bbl. and 81 bbls. of tail. He said he got back 145 bbls. of -- cement to the surface and USlT log would be run. I called Nick 11-12-96 and he said the log showed cement to surface, but they could not get all the way to botton due to contaninated mud. He said they got to 3540' and TD was 4069'. Summary: I witnessed the BOPE test on Doyon rig 14 drillng ARCO's DS 4-49 - test time 12.5 hours - 8 failures.

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.

The G&I operations have been discontinued for the summer months (since July 23,' 96) and will not be started until this well has run and cemented the intermediate casing (7-5/8" casing). Pressures in the subsurface interval below 4000'TVD are expected to be normalized from the higher pressures present during injection. There still exists the possibility of pressure in exess of the expected 9.7ppg, to minimize this risk the surface casing will be set above the T5 (SV3) sand which is above the uppermost interval of potential overpressure. Heavy weight mud will be on standby at the nearby Baroid mud plant to assist in the event pressures exceed the expected 9.7ppg. Well Control: Well control equipment consisting of 5000 psi W.P. pipe rams, blind rams, and annular preventer will be installed and is capable of handling maximum potential surface pressures.

Kick off and build angle at 2.5°/100' to 30.8° at 52.97° azimuth by 2732'MD. Continue with constant angle and azimuth to the surface casing point at 4072'MD, 3825'TVD. Set 10-3/4" casing and cement same to surface. Plan to run a screw in float collar for cementing to surface. Nipple up BOP's and test same to 500/5000 psi. Test casing to 3000 psi for 30 minutes. Note AOGCC witness or waiver on the morning report. P/U 9-7/8" BHA,(with MWD-GR) drill 20' new hole and perform LOT. Carefully monitor for overpressure from below the casing shoe until the full Ugnu has been drilled. Maintain close contact with the Bariod mud plant who can provide high weight mud if required. Contiunue to hold the borehole tangent to 9284'MD, 8301'TVD. At that depth begin a build and turn at 8°/100, to the final horizontal section beginning. The wellbore will be at 88.92° angle and 125.27° azimuth at the 7-5/8" casing depth. After a wiper trip POOH to run DP conveyed logs from the top of the SAD (9667'MD) to TD. These logs will include: GR-RES-NEU-DEN-Sonic. If requested by the Asset an additional run of RFT logs will be made across the Ugnu interval. Make a cleanout run. POOH and lay down drill pipe. Run 7-5/8" L-80 and 13 chrome casing and cement same, displacing with mud. Open the DV tool placed at about 7500'MD (below the Ugnu) and cement the annulus to 500' below the 10-3/4" casing shoe. After WOC for 4 hours, pump down the 10-3/4" X 7-5/8" annulus to ensure that the annulus is open for future pressure monitoring. Test casing to 3500 psi for 30 minutes. Test surface equipment to 500/5000 psi. P/U 6-3/4" BHA, MWD w/GR & 3-1/2" drill string. Drill out with the displacement mud which is to be at least 0.5 ppg heavier than the horizontal drilling fluid, then displace to the Baradrill-N system. Drill ahead and continue the lateral section per directional program. TD for the section is prognosed at 11079'MD and 8845'TVD. . Run 4-1/2" chrome tubing (slotted and solid) to place the packer and hanger with 150' of overlap into the 7-5/8", be sure to run an "X" nipple 1 joint below the packer. Run 4-1/2" chrome tubing to place the WLEG at 100' above the top of the SAD (approx. 9567'MD). The SSSV on this well is to be placed near 500'MD. 8. ND BOP and NU tree assembly. Test tree assembly to 5000 psi. 9. Freeze protect the annulus. 10. 11. Set packer, test tubing. Test annulus. Secure well, release rig.
