Well 1R-01A was replaced by 1R-01B (permit # 200-156, AP1 # 50-029-21404-02) when the permit was approved 10/05/2000. The replacement well incorporates an extension to a new bottom hole location using the existing well bore. This extension, along with the original hole, will be used for production of hydrocarbons. A review of both well files indicates administrative abandonment of the originating well bore is appropriate according to current AOGCC procedures for wells where additional permitted extension is drilled from an existing well bore. 20 AAC 25.005(a) requires a Permit to Drill for each hole drilled below the conductor unless drilled to straighten the original hole, sidetrack junk, or correct mechanical difficulties. In addition, AOGCC data bases require each conductor has only one permit number and AP1 number. Administrative abandonment of the original permit only eliminates duplication in the databases. Information for the original well and its replacement will be maintained in their respective files. Statistical Technicia~,tl,-~__,~ j~~Reservoir Engineer The operator has been notified of this action. All future correspondence with the AOGCC should reflect the new permit number, API number and well data.

The well is designed to penetrate and further develop the production potential of the Kuparuk sands in the vicinity of 1R pad. The well is designated as a horizontal sidetracked production well, exiting from the existing 7" intermediate casing of the 1R-01 well. A 3-1/2" production liner will be run and cemented and the well will be completed with 3-1/2" tubing. Please find attached information as required by 20 AAC 25.005 (a) and (c) for your review. Pertinent information attached to this application includes the following: 1) 2) 3) 4) Form 10-401 ApplicatiOn for Permit to Drill per 20 AAC 25.005 (a). Fee of $100 payable to the State of Alaska per 20 AAC 25.005 (c) (1). A directional plat showing the surface and bottomhole locations proposed for the well per 20 AAC 25.005 (c) (2). Directional plots and proximity calculations in accordance with the requirements of 20 AAC 25.050. C V hi' 7) 8) ARCO does not anticipate the presence of H2S in the formations to be encountered in this well. However, H2S monitoring equipment will be functioning on the rigs as is the standard operating procedure in the Kuparuk River Unit drilling operation. 5) A complete proposed casing and cementing program is attached as per 20 AAC 25.030. A wellbore schematic is also attached visually depicting the proposed well and completion design. 6) The drilling fluid program, in addition to the requirements set forth i~, 20 ~C 25.033 are a~ached in this APD package. A copy of the proposed drilling program.

Diverter, BOPE and mud fluid system schematics for Pool 6 are on file with AC)GCC. Maximum anticipated surface pressure (MASP) while drilling the production hole is calculated using a KOP leak-off of 13.5 ppg EMW (0.70 psi/ft) and a gas gradient of 0.11 psi/ft. This shows that formation breakdown would occur at a surface pressure of 3,097 psi. MASP = (5249 ft)(0.70 - 0.11) = 3,097 psi Based on offset well data, reservoir pressures in the Kuparuk sands in the vicinity of 1R pad are expected to be -3,500 psi (0.54 psi/ft). Assuming a 150 psi overbalance is required to safely drill and trip in this formation, then a required mud weight of 10.9 ppg can be predicted as the maximum mud weight needed to safely drill in this formation, assuming a TVD of 6,432'. Target (Kuparuk C) ( 3500+ 150)/(0.052'6432 )= 10.9. Hazards · This well will penetrate -160' of HRZ at 16° in the 6-1/8" section. Good drilling practices, including optimized flow rates of 240-250 gpm, slower trip and connection speeds, pumps at 40% when reaming connections, larger nozzle area for reduced sidewall erosion, all will assure a trouble free interval. · There is I known fault in the reservoir interval, anticipated to be ~30' throw. Lost circulation across the faults will be controlled with non-productive zone LCM pills. · Lost circulation across the fault, into the reservoir matrix, or wellbore "breathing" into exposed shales as a function of excessive ECD (equivalent circulating density). ECD will be controlled and monitored with the addition of a PWD (pressure-while-drilling) sub in the BHA. Disposal Cuttings should be processed with the Pool 6 ball mill and transported to DS1R-18 for injection. Fluid Handling: All drilling and completion fluids and other Class II wastes to DS1R:18 for injection. Haul all Class I waste to Pad 3 for disposal. Cement rinseate must be processed through the MI unit prior to injection in DS1R-18. 1R-Ola Short Well Summary Pre-Rig Work: NOTE: If any problems are observed with the 7" packoff during pre-rig operations, notify the Operations Drilling Engineer, Pool 6 Company Representative and the wellhead manufacturer. Repairs will be made prior to initiation of rig work. 1. RU wireline and dummy off GLM's at 2279', 4295', 5543', 6234', 6672', 7113', 7487' and 7902'.

Continue in hole to CIBP and orient and set whipstock. 6. Displace well to milling/drilling fluid. Shear whipstock bolt and begin milling window in 7". Mill until 29' of BHA is in the open hole. Circulate well clean until no metal is seen in returns. Perform LOT to a minimum of 12.5 ppg. POOH and LD milling assembly. 7. PU 6V8" BHA and RIH. Displace wellbore to 10.9 ppg drilling fluid and drill 6'/8" horizontal wellbore to 12022' MD. Use MWD/GR/Res in real time for evaluation. 8. Run 3~/2'' solid liner to TD and cement. 9. Run 3'/2" L-80 standard Kuparuk gas lift completion. Circulate freeze protection to 2200'. Sting SBE into PBR on top of liner top packer. 10. Set and test TWCV to 1000 psi. ND BOPE, NU Tree.

Mill window in straddle interval thru 3-1/2" tubing and 7" casing. Directionally drill a horizontal well from the existing wellbore. Complete with 2-3/8" slotted liner. Intended Procedure: · Cement squeeze the existing perforations and strad ,cl41e interval with 17 ppg cement. Leave top of cement above GLM at 79~,1~( WOC. · Underream cement down to 2-7/8" x 3-1/2" XO at 8136'. · Install mechanical whipstock. Mill window at 8122' through 3-1/2" and 7"casing. Drill 10' of formation and perform leak off test to 0.5 ppg above the highest anticipated mud weight. Plans are for drilling this sidetrack overbalanced with a kill weight mud. · Directionally drill 2-3/4" x 1658' horizontal well to access Kuparuk A reserves. · Run 2-3/8" slotted liner to TD. · Place on production. Drilling fluids will be injected into disposal well 1 R-18. November 10, 1998 Kuparuk 1R-01A Potential Drilling Hazards POST ON RIG No H2S gas is anticipated from this well. BHP: 2900 psi ~ 6282' TVD, 6200'ss (8.9 ppg EMW) estimated pressure. Reservoir frac gradient is -0.8 psi/ft or 15.4 EMW. Plans are to drill with 9.5 ppg mud which provides sufficient over- balanced pressure. Perform a leak-off test to 10 ppg. Maximum anticipated WHP w/full column of gas' -2300 psi assuming O. 1 psi/ft gas gradient. · No gas saturated intervals are expected. ARCO Alaska, Inc.
