PO Box 196612 Anchorage AK 99519 Re: Cancelled or Expired PTD's. 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. The following files are scheduled to be released October 1,2001.

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 in the treatment of these kinds of applications for permit to drill. 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 remain unchanged. The APl number and in some instances the well name reflect the number of preexisting redrills and or multilaterals 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 drill. The APl number for this cancelled or expired permit is modified so the eleven and twelfth digits is -95. The well number for a cancelled or expired permit is modified with an appended XX. CANCELED PERMITS ARE RELEASABLE 2 years from the date on the letter received from the operator requesting the permit canceled.. (Memorandum January 23, 1997 by Dave Johnston, subject: Canceled and Expired Permits) EXPIRED PERMITS ARE RELEASABLE 2 years from the date on the application was issued by the commission, unless the operator ask for extended confidentiality. AOGCC database has been changed to reflect these changes to this permit.

Diverter, BOPE and mud fluid system schematics on file with AOGCC. Bottom hole pressure is expected to be 3600psi @ 8926' TVDSS. Maximum expected surface pressure is therefore 2699psi (assuming gas column of 0. lpsi/ft). Drilling Hazards/Contingencies The main production target for this well is Zone 4. Drilling Close Approaches No drilling close approaches are expected for this well H2S Drill Site 13 is considered to be an H2S Drill Site - highest readings encountered are 122ppm in 1/97 although lower readings have been recorded recently. The scope and objectives for H2S op- erations are outlined in SSD's 'H2S- Standard Operating Procedure(SOP)'. When decompleting the well, until the packer has been removed, all fluids circulated from the well must be taken down an adjacent production flowline to avoid potential rig crew exposure to H2S. Intermediate Section There is no intermediate section to be drilled on this well and hence precautions concerning Kin- gak are not considered here. Production Section Faults are known to be conductive in the Drill Site 13 area. Although, no faults are expected to be crossed while drilling this wellbore, losses have occurred in the past while drilling both Shublik, and Zone 4. Normal lost circulation precautions are to be taken while drilling this well, and a close eye kept on the fluid system. Stuck pipe has been recorded in the Sag but only on one well in which a stiff hole opening assembly was run into a previously cored section, hence stuck pipe is not expected to be a severe problem. The pad data sheet indicates that normally, low reservoir pressures should be expected on DS 13. However, the closest existing well to the proposed well- bore is an injector which has raised the local pore pressure - the geological pore pressure prognosis based on this offset well has a relatively high value of -7.8ppg. Differential sticking should not be a problem with Quikdriln in the hole as long as severe losses due to faulting are not encountered. Kick Tolerance The kick tolerance for the 7" whipstock exit point would be an infinite influx (annular volume) as- suming an influx at the 12,855' TD. This is a worst case scenario based on a 7.0-8.0ppg ppg pore pressure and a minimum fracture gradient of 10.0 ppg with a 8.8 ppg mud in the hole. Note that the original well provided a 11.9ppg fracture gradient at 9-5/8" casing shoe when drilling the original 8-1/2" hole. Disposal All cuttings should be hauled to the ball mill at CC-2A for disposal. Haul all drilling and completion fluids and other Class II wastes to CC-2A for injection. Haul all Class I wastes to Pad 3 for disposal. Operations Summary Pre-Rig Work 1. Pull the 4-1/2" SSSV. Valve is set at 1922' MD. 2. Lay an LCM pill in the 7" liner across the perfs from PBTD to the tubing tail at 9,702'. Ensure the well is static with no fluid losses. Note that this well has an Alpha Soft Set patch at 9,491' (ID 2.687") which is not retrievable. 3. Test 4-1/2" tubing x casing annulus from the production packer at 9,628' to surface to 3000 psi for 30 minutes (holding pressure on tubing if necessary). 4. Chemically cut the 4-1/2" tubing as per current best recommended method at 9,488', 3' into the joint : immediately below the last GLM. The tubing patch at 9491' has a 2.687" ID restriction which will not allow a chemical cutter to pass through. This leaves a 6' gap between the GLM and the tubing patch. Note also that the tubing is internally plastic coated, and therefore a multiple anchor and double add cylinder cutter will be required. A special spacer will be used on the chemical cutter to allow the cutter anchor to set above the last GLM. Note: Should the pre-rig work be unable to cut at 9488' for any reason, the cut will be made in the middle of the first full joint above the last GLM. 5. Circulate with seawater to ensure the well is dead and freeze protect the well to -2200'. Bleed tubing and annuli pressures to O psi. 6. Test the Gray 9-5/8" mandrel packoff to 5000 psi for 30 minutes and tubing hanger to 5000 psi for 30 minutes. Function lockdown screws. 7. Set a BPV in the tubing hanger and secure the well. 8. Notify the operations engineer of the well's status upon resolution of the work. Rig Operations Abandonment * Notify the AOGCC for witnessing rig operations on BOPE testing and w/th intent to plug and abandon * 1. MIRU Nabors 22E. 2. · Circulate out freeze protection. Set TWC using a test dart in the BPV. 3. Nipple down tree. Nipple up and test BOPE. 4. Pull 4-1/2" tubing from cut at 9,488'. 5. Washover and latch the tubing with an overshot. Rotate to release the tubing anchor and POOH. Check to ensure that the Alpha soft set patch was retrieved with the remaining tubing. 6. Mill and recover the Baker production packer at 9,628' and tailpipe. The packer has a Mill-out Exten- sion and may potentially be retrieved with the milling assembly. If not, a fishing run will be required. 7. RIH with a 7" RTTS and test the 7" x 9-5/8" casing from 10,000' to surface to 3000 psi for 30 minutes. 8. RIH with a 7" Halliburton cement retainer on e-line with GR/CCL. Tie-in to the top of the Sag River ("~10,047') and set the cement retainer top at -~10,070', 23' below TSag. 9. The top of the cement retainer will be set with open Sag River perforations above. The planned 4.5" liner top packer will lap the highest perforation by 150' minimum and will be fully cemented. 10. RIH with cementing string. Sting into the retainer and establish an injection rate with seawater (close annular preventer). Pump 34 barrels of 15.6 ppg Premium cement to fill the casing volume between PBTD at 10,858' and the cement retainer plus squeeze 5 barrels to the perforations. Unsting and circu- late out any excess cement. Sidetrack 1. RIH with 7" whipstock and set 20° right of high side. KOP should be 10,050' (3' below Top Sag). 2. Displace the well with 4% Quick&il and mill the window through the existing perforations. Monitor torque / drag closely due to the perforations. 3. Directionally drill building from 30-90° angle. Drill the --~2,805' of 6" horizontal section with MWD / GR / 4 Phase resistivity to a planned TD of 12,855'. 4. Run drill pipe conveyed Platform Express/Sonic logs from TD to 7" window. 5. Run and fully cement a 4.5" L-80 production liner. The production liner will have a RA tag in a coupling spaced at TSag. Displace the cement with clean seawater. Land the liner top packer at 9,899' or shallower, a minimum of 150' liner lap above the top existing perforation at 10,049' is required. 6. Test the 4-1/2" x 7" x 9-5/8" casing from the 4-1/2" landing collar to surface to 3000 psi for 30 min- utes. 7. Run a DPC 2.75" perforating assembly shooting locations determined from LWD and DPC logs. Ap- proximately 50% of the drilled interval will require perforation. 8.
