Dear Mr. Ruedrich, Please be aware that XTO Energy Inc. did not proceed with the P&A of the C24A-23LN to pursue the Sidetrack Re-drill of the C24A-23LN2. It was decided to convert the C24A-23LN to a water injector to provide pressure support to the West Flank Hemlock after performing a reservoir study and reviewing the economics. XTO has just recently completed this conversion and has filed the necessary 10-407 Report dated August 1, 2003. Therefore, please cancel Permit #302-378 for the P&A dated 12-11-02 and the Permit #202-255 dated 1-13-03 for the re-drill. If you have any questions or require additional information, please contact me at (432) 620-6743. Sincerely, ?aJ ¡.-Çt Paul L. Figel Sr. Production Engineer J \-\ \ G I NA_ IMJDMS 8Ft ð« H: n 1::;.

This permit to redrill does not exempt you from obtaining additional permits or approvals required by law from other governmental agencies, and does not authorize conducting drilling operations until all other required permits and approvals have been issued. In addition, the Commission reserves the right to withdraw the permit in the event it was erroneously issued. Operations must be conducted in accordance with AS 31.05 and Title 20, Chapter 25 of the Alaska Administrative Code unless the Commission specifically authorizes a variance. Failure to comply with an applicable provision of AS 31.05, Title 20, Chapter 25 of the Alaska Administrative Code, or a Commission order, or the terms and conditions of this permit may result in the revocation or suspension of the permit. Please provide at least twenty-four (24) hours notice for a representative of the Commission to witness any required test.

Smith, Drilling / Operations Manager XTO Energy Inc. 3000 N. Garfield, Suite 175 Midland, Texas 79705 Dear Mr. Smith: XTO Energy Inc., by application dated December 26, 2002, requests approval to drill the MGS C24A-23LN2 well. This horizontal well will be the third producer in the SW ~ of Section 23, T8N, RI3W, Seward Meridian ("SM") and also the fifth producer in the NW ~ of Section 23, T8N, R13W, SM. The Alaska Oil and Gas Conservation Coml11ission ("Commission") understands that drilling and completion of this well will increase recovery of reserves from this structurally cOl11plex portion of the Middle Ground Shoal Field.

Based on offset well data, the highest formation pressure expected in the 6" and 4-1/8" hole sections is 3,500 psi at the TD of 10,005' TVD (or 0.345 psi/ft). Well-documented fracture gradient data for this area indicates that the fracture gradient at 8,841 'TVD where the window has been milled in the 7" casing is 0.764 psi/ft. Complete evacuation of the wellbore, except for a 0.11 psi/ft gas gradient, is assumed. Reservoir hole section MASP (pore pressure) MASP (fin breakdown) (10,005 ft)(0.345 - 0.11) = 2,351 psi (8,841 ft)(0.764 - 0.11) = 5,782 psi Therefore, MASP in the 6" and 4-1/8" open hole sections is 2,351 psi and the BOPE will be routinely tested to a working pressure of3,000 psi. ) .) Well Proximity Risk: The nearest wellbore to that of C24A-23LN2 is C13-23. This well is planned to pass 260' from Well C13-23 at a depth of 11,463'. Drillin2 Area Risks: The primary drilling risks in the C24A-23LN2 area are those of stuck pipe in the coals of the Hemlock Formations and lost circulation within the Hemlock Fm. The risk of stuck pipe in the Hemlock coals will be countered in three ways: 1.) Drillers experienced at drilling the formations of the Cook Inlet Basin will be used. 2.) Bit selection will include those which experience a slower rate of penetration when entering coal beds, thus giving warning of coals being encountered and preventing the BHA from entering them until the coals can be reamed open. 3.) The well's kick-offpoint will be below the most severe coals lying just above the Hemlock Formation. Lost circulation in the Hemlock interval will be treated with conventional LCM. While experience has shown that this will be effective, the option will also be maintained of running casing at this point, if necessary, in order to allow the lowering of the mud weight to aid in solving a severe lost circulation problem. Disposal of Muds and Cuttin2s: MGS Platform C has a dedicated Class II disposal well. All waste wellbore fluids will be injected down the disposal well as will cuttings after they are ground.

Commission Anchorage Ms. Cammy Oechsli-Taylor, Chair Alaska Oil and Gas Conservation Commission 333 West ih Ave., Suite 100 Anchorage, Alaska 99501 Re: Application for Permit to Drill: C24A-23LN2 Dear Ms. Oechsli-Taylor: XTO Energy, Inc. hereby applies for a Permit to Drill an offshore development well from Platform C in the Middle Ground Shoal Field of Cook Inlet. The well is planned as a sidetrack of the existing C24A-23LN well bore in order to replace that damaged well bore. Approval of the associated pre-drilling work plan for the existing wellbore has been requested via a Sundry Notice submitted under separate cover. The anticipated spud date of C24A-23LN2 is approximately January 13,2003. The well will be sidetracked just above the Hemlock reservoir from the existing 6" open hole section in the plugged-back C24A-23LN well. A new 6" hole will be directionally drilled to 10,600' and a 5" liner will be cemented into place from 9,182' to 10,600' MD. A 4-1/8" hole will then be drilled horizontally in the hemlock reservoir to TD at 13,069' MD and a 3-V2" slotted liner will be set in place to TD. A 2-7/8" gas lift completion will then be installed. 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) Form 10-401 Application for Permit to Drill per 20 AAC 25.005 (a). 2) Fee of $100.00 payable to the State of Alaska per 20 AAC 25.005 (c) (1). 3) A directional plat showing the well's proposed surface and bottomhole locations per 20 AAC 25.050 (c) (2). 4) Directional plots and proximity calculations in accordance with the requirements of 20 AAC 25.050. 5) Diagrams and descriptions of the BOP equipment to be used as required by 20 AAC 25.035 (a) (1) and (b) were previously submitted to your office and are on file. 6) A complete proposed casing program is attached as per 20 AAC 25.030. 7) The drilling fluid program, in addition to the. requirements of 20 AAC 25.033 are attached. 8) A copy of the proposed drilling program is attached. 9) XTO Energy does not anticipate the presence of H2S in the formation to be encountered in this well. However, H2S monitoring equipment will be XTOEnergyInc.· 3000N.Garfield· Suitel75.
