ITEM 1a: Classification of Service Wells: Gas Injection, Water Injection, Water-Alternating-Gas Injection, Salt Water Disposal, Water Supply for Injection, Observation, or Other. Multiple completion is defined as a well producing from more than one pool with production from each pool completely segregated. Each segregated pool is a completion. ITEM 4b: TPI (Top of Producing Interval). ITEM 8: The Kelly Bushing elevation in feet above mean low low water. Use same as reference for depth measurements given in other spaces on this form and in any attachments. ITEM 13: The API number reported to AOGCC must be 14 digits (ex: 50-029-20123-00-00). ITEM 20: True vertical thickness. ITEM 22: Attached supplemental records for this well should show the details of any multiple stage cementing and the location of the cementing tool. ITEM 23: If this well is completed for separate production from more than one interval (multiple completion), so state in item 1, and in item 23 show the producing intervals for only the interval reported in item 26. (Submit a separate form for each additional interval to be separately produced, showing the data pertinent to such interval). ITEM 26: Method of Operation: Flowing, Gas Lift, Rod Pump, Hydraulic Pump, Submersible, Water Injection, Gas Injection, Shut-In, or Other (explain). ITEM 27: If no cores taken, indicate "None". ITEM 29: List all test information. If none, state "None".

An MITIA was performed on 6/3/00 which failed with a leak rate of 2 bpm @ 2300 psi. The AGOCC was notified on 6/4/00. A Leak Detect Log (LDL) on 6/17/00 found a large leak in the coiled tubing completion @ 8309' and a small leak near the tubing hanger. A tubing tail plug was set and the well passed a Combination MIT T x casing (CMIT T x IA) @ 3000 psi on 6/23/00 (attached). Engineering is evaluating the long-term repair options for this well. This sundry request is to continue water (only) injection into the well, based on the following information: · A combination MIT (3-1/2" tubing x 5-1/2" casing) passed 6/23/00 @ 3000 psi, demonstrating mechanical integrity of the casing and injection is into the approved zone; · The Leak Detect Log on 6/17/00 identified the leak points in the tubing; ° Normal wellhead injection pressure is 1200-1500 psi on produced water injection service. ° Continue water injection (only) into the well; -'1 ° Perform 2-year combination MIT 3-1/2" tubing x 5-1/2" casing against a tubing plug; x~. ~ Monitor'wellhead pressures dailY; ~ · Report monthly the daily injection rate, tubing pressure and annulus pressure; ~ ~,~ Shut-in and secure the well should MIT's or wellhead pressures indicate problems and notify // ~ the AOGCC~.~.~ ~ RECEIVED ,.

Well 13-31 (PTD 194-040) failed an MIT-IA today (6/3/00). Leak rate was 2 BPM 2325 psi. 13-31 is currently injecting produced water, approximately 3000 bwpd 850 psi. Leak location is unknown. It is completed with 3-1/2" coiled tubing inside 5-1/2" production casing. We are planning to leave the well online and running a leak detect log to locate the leak point. Call if you have any questions. Joe Anders, PE Problem Well Specialist Phillips Alaska, Inc.

When I arrived the crew was just finishing nippling up the Diverter line, this line terminated within fifty feet of the rig and at my request the snow that had blown in the end of the 16 "vent line was removed and a layer of visqueen was placed over the end. The annular preventer was a 20" Hydril type GK with a single 16" vent line. When functioned, the diverter completed it's cycle in 28 seconds which is a good time for this size assembly. The vent lines Knife valve was quick and simultaneous. I made a tour of the rig and found it to be in good shape. The rig was passed to drill surface hole at this point.

Commissio~ Anchorage BP EXPLORATION ARCO Alaska, Inc. To: Mr. David W. Johnson Chairman Alaska Oil & Gas Conservation Comm{ssion 3001 Porcupine Drive Anchorage, Alaska 99501 Subject: Prudhoe Bay Unit 9-5/8" Surface Casing Design Date: March 31, 1994 Dear Commissioner Johnson; This letter follows a telephone conversation and verbal approval from Jack Hartz to proceed with 9-5/8" 401b/ft, L-80, BTC casing for surface casing in the Prudhoe Bay Unit. Prudhoe Bay Drilling has just completed the desigr~ and performance analysis for this application, and in ail cases the casing exceeded the mi~knum casing design safety factors for tension, burst, and collapse as outlined in the BPX Casing Design manual. Three different wellbore, geometry's and five load scenarios were checked, (attachments 1 through 3). The casing shoe setting depth was assumed to be 5000' TVD since this is the maximum setting depth per the PBU Field Rules. A hole angle of 0° 30° 60°was built at a 3°/100 build rates with a 6o100' dogleg at 2100' TVD were evaluated. The maximum anticipated surface pressure used was 3500 psi which corresponds to a maximum BHP of 4380 psi ~ 8800' SS assumirtg a 0.1 psi gas gradient to' surface. The basic load scenarios and ballooning, force formula were taken from the BPX Casing Design Manual. The bending force, biaxial burst, and triaxial burst formulas were taken from the ARCO Drilling Manual. The pipe body yield strength, internal yield pressure, and the collapse method and calculations were taken from APl Bul 5C3. Based upon a discussion between Greg Walz, ARCO SR. Drilllng Engineer and Blair Wonzell with the AOGCC, permafrost conditions will not be an issue for this pipe because it is L-80 casing. Past permafrost casing strain evaluations have shown the L-80 grade or less will be sufficient in the permafrost and qualification modeling will not be necessary. BaSed on our analysis we have found that performance safety factors are equal to or exceed 1.3 for all load scenarios tried. Therefore, Prudhoe Bay Drilling believes 9-5/8", 40#, L-80, BTC casing is acceptable for surface casing for use in the Prudhoe Bay Unit. T. W.

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. The blowout prevention equipment (BOPE) must be tested in accordance with 20 AAC 25.035; and the mechanical integrity (MI) of the injection wells must be demonstrated under 20 AAC 25.412 and 20 25.030(g)(3). Sufficient notice (approximately 24 hours) of the MI test before operation, and 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 tests. Notice may be given by contacting the Commission petroleum field inspector on the North Slope pager at 659-3607.
