The following summarizes the procedure required to prepare H-36 for sidetracking and is submitted as an attachment to Form 10-403. A schematic diagram of this proposed completion is attached. Note that the 4 ½" x 7 5/8" production packer is located in lower Zone 4. Cement will be placed above this production packer to enable a sidetrack window to be placed mid-Zone 4. 1. A Tubing Integrity Test was successful on 1/27/00. 2. A whipstock drift was run through the tubing on 1/29/00. 3. Horizontal section perfs will be shut off with a bridge plug set in the tubing tail at approx. 11,145' and tested to 1500 psi. 4. The 4 ½" tubing will be punched at approx. 11,090-94' and circulation to the IA established. 5. A cement retainer will be set in the 4 ½" tubing at approx. 11,070'. 6. Service coil will squeeze cement through the retainer and up the 4 ½" x 7 5/8" annulus to a height of approx. 10,500'. 7. E-line will set a whipstock anchor at approx. 11.010' and determine anchor lug orientation. 8. Drilling coil will rig up and install the whipstock into the anchor and mill a notch into the 4 ½" tubing. A 2200 psi pressure test will then be performed to confirm IA cement integrity as this cement column will replace the original production packer. Upon achieving a competent pressure test, the remaining window milling through the 4 ½" and 7 5/8" strings will be performed. Steps 3 - 7 are scheduled for Mar. 15 - 19, and step 8 is scheduled for Mar. 31, 2000.

Commission 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 (1'.0-403) 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. From those records, we show the following wells not listed on your report were used for annular dispOsal: NOV ! 2002 ,Annular Disposal Letter 12/14/98 ! · Endicott wells 1-23/O-15, 1-61/Q-20, 2-40/S-22 · Exploration well Sourdoueh #3 - ~zoo ~ ,~-~ · Milne }'ointwellsF-06, H-05, H-06, J'13, L-24 - · PBUwells-18-30, 18-31, 14~,4,.S~-43, E,.-34, E-36, G-04A, andS-33' :}- o$ z. 33- ~.~ ' ct c, o':/ · Individual logs are provided to ~ou fei~ these ~'ogs/ts we~l. · Finally, our records show that the B-24 outer annulus was left open (see attached correspondence) Thank you for the opportunity to provide clarity to these records.

Blair Wondzell Date: Oct 23, 95 From: Zeljko Runje "~~ Subject: Permit to Drill for H-35 and H-36 ( Both Wells WOA ) Please amend the submission to the Permit to Drill H-35 and H-36 to allow annular injection in these wells ( H-35 and H-36 ) upon completion of cementing of the long string. These permits are already approved by AOGCC. Information on USDW's.(Underground Source of Drinking Water) 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. Surface Casing Setting Depth Since there is no USDW, the surface casing setting depth is set based on recommendation to prevent communication to surface. These require setting the surface shoe at 10' above SV3 formation. SV3 formation is located at @ 3121' TVDBKB for well H-35 and it is expected to be at 3127' TVDBKB in the well H-36. ( NOTE: SV3 could warry by a few feet on each pad and from the well to well. These depths are only prognosed depths. ) Surface Casing design ~ ~-Z,"-t'" .

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 detailing the confining layers ,porosity and permeability of the injection zone on 7-24-95. Pumping into the hydrocarbon reservoir will not occur. Please call me at 564-4825 if there are any questions. Thanks.

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 (DOPE) must be tested in accordance with 20 AAC 25.035. Sufficient notice (approximately 24 hours) of the DOPE test performed before drilling below the surface casing 'shoe must be given so that a representative of the Commission may witness the test.
