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".

From a window in the 4 1/2" liner, milled off ,/ of a mechanical whipstock, E-39A will build from Zone 1 kick off point, to a Z1 B target. A cement ./ downsqueeze will P&A the parent well perfs. The following describes work planned to prep for sidetracking and is submitted as an attachment to Form 10- 403. A schematic diagram of the proposed sidetrack is attached for reference. 1. Confirm mechanical integrity 2. Set through tæbiVl{hiPstock 3. Down squeez 20þ}~1 13.8ppg cement. 4. Clean out to r~tock 5. Pressure test squeeze to 1000psi Work will likely be performed in the 2nd week of March. Nordic 1 is scheduled to arrive on the well - 18th March. /l).. J~cdt M.S.

Com~ssion · Anchorage On October 28, 1998 you requested an update from Shared Service Drilling regarding Annular DispOsal Records from July 25, 1995 through preSent time. We compared your list with our records and are able to provide you with the following data: · Individual Annular Disposal Logs from the SSD database which coincide with the approved wells on your attached AOGCC Annular Log, The.SSD records are prOvided to yOu in the same order as listed on your log. · There were some wells on your list which were not injected into. These wells are identified as follows: · Endicott wells 1-03/P-16, 1-65/N-25, 1-59/0-24 ' · EXploration well Pete's Wicked #1 · Milne Point wells E-22, E-23, F-O1, L-16, J-19, L-25, F-30,,L-21, K-38, NMP #1 & #2, K-05, K-02, H-07, K-25, K-37, E-17, F-21, K-30, K-34, K,21i, F-66, K-06, K-54, K-33, F-49i, K-18 · PBU Wells E-38, 18-34, 15-42, 'S-29A, 15-46, B-36, 15-43, 11-38 · The reason many of these annuli were not used is because the waste materials generated from these wells were injected into other approved annuli. Hopefully the injection logs submitted with this letter will clarify this. In addition, please note that our records show: · The wells listed above in italics were permitted but not used for annular disposal, · The wells listed above in BOLD were not Permitted for annular disposal. Wells drilled after June 6, 1996 were required by SSD procedure to be permitted with a Sundry Approval (10-403) form. Our records show that no Sundry Approval for Annular Disposal was filed for these wells. Wells drilled between July 25, 1995 and June 6, 1996 were automatically approved for annular disposal with the Permit to Drill. · We also provide .you with a cumulative report from our database of records from July 25, 1995 through the present.

As discussed this morning we propose setting three plugs in this well as detailed in the attached form. This will allow us to retain the wellbore for potential future sidetrack or service well use. ' We would like to keep the well's 9-5/8" x 7" annulus available for the injection of liquid wastes. There are no other well annulii on this pad for injection. The annulus for MPB-24 was approved for injection as part of the permit dated 25 January 1996. The annulus will be freeze protected before moving the rig. Thank you for your help in this matter.

The flowlines from the adjacent wells were in such close proximity to the rig that it necessitated terminating the 16" vent line at 47'. I authorized the rig to put a slight upswing in the vent line so as to direct the possible blast up and over the existing flowlines. This allowance was for this well only and should be avoided as the outside ambient temperature drops in the upcoming months. The Diver[er functioned properly with a quick closure time of 52 seconds. I found a problem with the accumulator set, Once the Diver[er was actuated there was a tendency for the hydraulic reserves to bleed down. This was due to the accumulators valving not completing its travel. Mike Downey will have this repaired and report to me. SUMMARY: I witnessed the function test of the Diver[er system on Nabors rig ¢28-E. I found a problem with the rigs accumulator system.

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 659-3607.

V H H E-39 Well Plan Page 3 Date Revised' 8/17/95 E-39 Addition to Permit to Drill Request for Annular Injection Disposal: Cuttings Handling: Cuttings should be hauled to the ball mill at CC-2A. Fluid Handling: All drilling and completion fluids can be annular injected. Request to have well E-39 for annular pumping. Request to AOGCC for Annular Pumping Approval for E-39: 1. Approval is requested for Annular Pumping into the E-39 9-5/8" x 7" casing annulus. . Aquifers in the Prudhoe Bay Field Western Operating Area (including K Pad) have been exempted from Class II injection activities by the AOGCC by Aquifer Exemption Order #1 as referenced in Area Injection Order #3. There are no domestic or industrial use water wells located within one mile of the project area. 3. The 9-5/8" casing shoe will be set at 3612' MD (3600' TVD) which is below the Permafrost and in shale formations in the Sagavanirtok above the Ugnu Formation. . The burst rating (80%) for the 9-5/8" 40# NT-80 casing is 4,600 psig while the collapse rating (80%) of the 7" 29# L-80 casing is 5,615 psig. The break down pressure of the Ugnu formation is 13.5 ppg equivalent mud weight. The Maximum Allowable Surface Pressure while annular pumping is calculated according to the following equation and is 4095 psi for a 10.0 ppg fluid in this well (Assumes worst case in which 7" casing is filled with gas). MASP - 5615 psig - ((fluid density ppg - 1.9) X 0.052 X 9-5/8" Casing Shoe TVD) 5. A determination has been made that the pumping operation will not endanger the integrity of the well being drilled by the submission of data to AOGCC on 7/24/95 which demonstrates the confining layers, porosity, and permeability of the injection zone. 6. The cement design for this well ensures that annular pumping into hydrocarbon zones will not occur.

Cement liner in place with sufficient cement to fill entire liner annulus. Make cleanout run. Test liner and liner lap to 3,500 psi for 30 minutes. Displace Xanvis KC1 mud with filtered seawater. ° Run 3-1/2" L-80 tubing with SSSV, GLM's, and 7" x 3-1/2" packer assembly. Circulate corrosion inhibitor into tubing annulus. Set packer and test tubing annulus w/3,500 psi. 9. Set BPV. ND BOPE. 10. 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 @ 8,000' 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 8.9 ppg to 9.0 ppg will be used to drill the Sadlerochit interval after intermediate casing has been set.
