Dear Gunkel: September 6, 2001 The Alaska Oil and Gas Conservation Commission ("AOGCC") approved the following referenced permit to drills. The AOGCC has a long-standing policy of releasing cancelled or expired permits two years from the date the application was approVed by the AOGCC.

Our adopted conventions for assigning APl numbers, permit numbers and well names did not specifically address expired or cancelled permits. This omission has caused some inconsistencies i, the treatment of these kinds of applications for permit to ddil. Operators have asked us to adopt formal procedures for this class of permit application in order to prevent future database disparities. If a permit expires or is cancelled by an operator, the permit number of the subject permit will remair unchanged. The APl number and in some instances the well name reflect the number of preexistin,( reddlls and or muitilaterals in a well. In order to prevent confusing a cancelled or expired permit with an active well or multilateral these case sensitive well identifiers will be changed for expired and cancelled applications for permits to ddll. The APl number for this cancelled or expired permit is modified so the eleven and twelfth digits is 9[ The well name for a cancelled or expired permit is modified with an appended xx. These procedures are an addendum to the AP! numbering methods descnbed in AOGCC staff memoranclum "Multi-lateral (wellbore segment) Drilling Permit Procedures, revised December 29, 1995. AOGCC database has been changed to reflect these changes to this permit.

This directly affects the conductor for the next planned Niakuk well, NK-65--1ocated in the western well row due north (plant north) of the existing NK-39. The surface location of NK-65 is between NK-18 and NK-19 which are currently set on 30' centers. In August of 1997, NK-39 was set on a 15' center between 18 and 19. Changing to 10' centers in this case requires the abandonment of this conductor. NK-65 and NK-64 can then be set on either side of the abandoned NK-39 conductor. Shared Services Drilling has arranged for the abandonment of NK-39 conductor and the subsequent installation and surveying of two 20" conductors to be set + 80'. A diagram describing the stipulated work is shown below along with the estimated coordinates (calculated geometrically) for NK-64 and NK-65.

The timing of these events is critical as Pool 7 could be ready to spud NK-65 by the 2n~ or 3r~ week in March. Please contact the Pool 7 Rig Representative if any on-slope coordination is required. Also, ensure that the installation contractor checks with the Lisburne Well Site Supervisor to make certain that the conductor work does not conflict with any previously scheduled well operations. Work Requested: Contractor is to supply all labor, supervision, equipment, tools, and materials to survey the cellars and subsequently remove and install the respective conductors as required. 2.) 3.) 4.) 5.) 6.) Survey and mark the conductor locations for NK-64 and NK-65. Contractor is to supply an "As Staked" survey showing the cellar locations and reference points. Cellar locations are to be marked with a flag at each drill point (center of each conductor) and each of the four reference points to the drill point (not to be the corners of the cellar boxes). For the existing well (NK-39), cut and remove the top 3.5 - 4 feet of the 20" casing leaving a long enough stub to weld a cap onto. Securely weld a plate (at least the thickness of the 20" casing, ~7/8") onto the NK-39 conductor stub. Remove the 8' cellar surrounding the now cut off conductor pipe. (It may be sensible to excavate for the installation of the two adjacent conductors before actually removing the NK-39 cellar. The NK-39 cellar will most likely be destroyed in the removal operation. If not, and the pipe is in satisfactory condition, it may be used for either NK-64 or NK-65. Set the conductors for both new wells in the proper position. There will be limited clearance between the NK-39 conductor stub and each the cellars for 64 and 65. The cellars may have to be "field fit" to maintain at least a one ft clearance between the conductor stub. See the diagram listed below NK-39 ctor stub Alaska 0ii & Gas Cons. Commission Anchorage RECEIVED JAN 29 1999 Install and set the conductors in the positions listed on first page. The top of each conductor should be cut approximately 18" above the pad level. Survey the "As Built" conductor positions and provide a new "As Built" survey with the X-Y coordinates and the finished grade elevations documented. The "As Built" is to be certified by a registered professional land surveyor. This survey will be used for well planning and state permitting purposes. 7.) 8.) Provide conductor installation reports containing the following: a) "As Staked" conductor locations with reference point positions. b) "As Built" plan showing the actual conductor locations, X-Y coordinates and grade elevations.

The maximum anticipated reservoir pressure is 4681 psia @ 9612' TVD. However their is a good possibility high pressure gas in the Ivishak formation. This was evident from NK-04 where an Ivishak Formation Gradient of 9.9 ppg was found. Lost Circulation/Faults 1. Major segment bounding fault to the North with wide fault zone to the NW of the target location. The fault dips northward so it will be closet to the wellbore at Top Kupamk and dip further away at the deeper horizons. 2. Deep Anithetic fault to the Niakuk faults SW of the target location 3. Expect a thick section of angular tuffs as seen in the NK-05 logs Close Approaches NK-18 and NK-19 will be shut in until surface casing is set. The largest close approach issues occur less than 1000' MD. Formations Expect to have a full section of angular and waxy Tuffs as seen in NK-05. The angular Tuffs are expected to be about 100 feet thick. This formation caused hole packoff problems in NK-41 and will need to be carefully monitored through out the Intermediate Hole Section. In addition, this well will drill through the Kingak shale which has caused sticking problems through out the North Slope. 5 8/11/97--SG NK-39 Well Plan "~" Rev 1 Well Control: Well control equipment consisting of 5000 psi WP pipe rams, blind rams, and annular preventer will be installed and is capable of handling maximum potential surface pressures.
