Commission Anchorage, AK 99501 Anchorage Re: Renewal of Suspended Well 10 -403 Status Kuparuk River Unit 3H -25A (PTD 199 -040) Dear Commissioner Seamount: ConocoPhillips Alaska Inc. (CPAI) hereby submits a request for renewal of the suspension status of Kuparuk River Unit well 3H -25A (PTD 199 -040) per 20 AAC 25.110. The well was visually inspected September 29, 2010 and the results submitted on a 10 -404. The condition of the well is noted on an attached schematic and 10 -403 form. Please note the following: - The perforation from original well bore are isolated with a cement plug. - The well is on an active pad. CPAI request the renewal of the suspension because the well is being held for future rotary side track development. Please call Perry Klein or me at 659 -7043 if you have any questions.

The rig was downloading the MWD tools when I arrived, after approximately two hours the test was begun. The test went very well with all BOPE components functioning properly and holding their pressure test with no leakage observed. The crew seemed well versed in their procedure, which indicated to me familiarity with this procedure. A tour around the rig showed much attention to housekeeping and preventative maintenance is standard for this rig, all in all a good looking rig. SUMMARY: I witnessed the weekly BOP test on Nordic rig #3. Test time 4 hours, No failures.

Well Control: Well control equipment consisting of 5000 psi working pressure pipe rams, blind rams, and annular preventer will be installed. Maximum anticipated surface pressure is estimated at 2649 psi and is calculated using a gas column to surface with a maximum expected formation pressure in the Kuparuk of 3300 psi and a gas gradient of 0.11 psi/ft. Therefore, ARCO Alaska, Inc. will test the BOP equipment to 3500 psi. See attached BOPE schematic. Drilling Hazards: Lost Circulation: Overpressured Intervals: Other Hazards: The suspect lost circulation zones throughout the Kuparuk field are the K-10 and K-5 intervals. The sidetrack 3H-25 A, will kick off out of the 7" casing below both the K-10 and K-5 intervals. It is uncertain if adequate cement exists behind 7" casing at the, planned kick-off window. If the Formation Integrity Test shows that the K-10 and K,5 intervals are not isolated and will not hold the desired equivalent mud weight, a cement squeeze at the window could be performed to help isolate these intervals. The kick-off point 'in 3H-25 A is below any zones which would be of pressure concern prior to weighting up for the Kuparuk interval.
