GPB Rotary Drilling Winton Aubert October 10, 2002 Mik Triolo, 564-5774 Well W-38Ll Migration to W-38a History Well History: Doyon 14 moved onto W-38 and was accepted on September 30th, 2002 at 22:00 hrs. The well was then killed by pumping a 100 bbl sized calcium carbonate pill required to seal off the existing perforations. The 4- %" tubing was then pulled from the well leaving a tubing stub at 13,720' MD. An attempt to retrieve the K- anchor from the production packer was made, failing due to the twist off of the collapsed tubing at -16' below the tubing stub. Several attempts were made to burn over the packer and retrieve it too try again to retrieve- the K-anehor, unsuccessfully. During the attempts 2 burn shoes and small sections of wash pipe were left down hole. The decision was made to abandon the deeompletion plan and give up production from the ,- motherbore and sidetrack out of the 9-%" casing into the Kingak. Several verbal conversations were had on October 8th and 9th explaining the issues and planned abandonment options. The plans submitted in this Sundry are as per those conversations. Please find attached a Sundry to abandon the perforations in the W -38 motherbore and the adjusted plan forward for finishing the W -38a sidetrack.

Establish a minimum distance of 5' from the W-39 and W-37 wellhouse. The well houses will need to be removed from all three wells prior to the rig move. No swab valves will need to be removed in preparation for the move over W-38. Discuss the move at a pre-job safety meeting and designate a spotter to ensure there is no danger of a collision. If it appears the 5' distance will be crossed, the move should be stopped, the rig backed up, and the move re-attempted. ~ W Pad is not designated as an H2S site, however Standard Operating Procedures for H2S precautions should be followed at all times. Water injection on W-Pad was initiated in late 2001, and H2S levels are expected to remain low until the waterflood matures. Recent H2S data from the pad is as follows: W -38 less than 10 ppm Adjacent producers at Surface: W-39 less than 10 ppm W-37 less than 10 ppm Adjacent producers at TD: Z-18 10 ppm W-09 10 ppm The maximum recorded level of H2S on the pad was under 20 ppm. ~ The perforations will not be abandoned due to the desire to retain production from the motherbore to capture the remaining reserves out to the Southeast. The well should be overbalanced by -80 psi at surface with the diesel down to 2,000' TVD. Prior to moving over the well check the wellhead pressure to verify the well is dead. ~,'m>.~~;';,;,; Job 2: Decomplete Well Hazards and Contingencies :» The top perforations are not isolated, therefore monitor the well for gain/loss prior to beginning decompletion operations and while pulling the tubing and packer. :» There is a confirmed section of collapsed tubing at 13,744' MD. The collapse point is expected to be across a 9.66' pup joint at 13,739 -13,748' MD. It is also very possible that the 4Y2" tubing string is highly corroded and sections of the tubing may have high wall loss, with several possible penetrations. Limit over-pull on tubing string to 80% of tensile strength, and if tubing will not pull free on initial attempt, RU e-line to make a second cut. :» It is critical to retrieve the K-anchor from the packer after laying down the tubing above the collapse point in order to recover the last GLM @ 13,748' MD. If the K-anchor does not come free then we will have to burn over the GLM in order to get to the packer below. This could require up to three trips to burn over the mandrel. :» NORM test all retrieved well head and completion equipment. '._.,-,.._.."."..."..,~("',..._..- Job 3: Run Whipstock Hazards and Contingencies :» Once milling is complete, make sure all BOP equipment is operable. Wash out BOP stack to remove any metal cuttings which may have settled out. 6 ) Greater Prudhoe Bay W-38L 1 Permit --) Job 7: Drill 6-118" Production Hole Hazards and Contingencies » Four expected fault crossings have been identified for this hole section (see the attached cross-section for details on fault throws and expected depths along the well path). Throws on these faults are small (10 to 25'), however the risk of encountering losses at these faults is considered to be low risk (10-20%). There is some extra time and money in the AFE to cover minor losses. Follow the LCM Decision tree if losses are encountered. » W Pad has a history of lost circulation events while drilling in the reservoir section. Typical loss rates have been in the 20 to 30 bph range, however there is a single case where W -12A crossed a fault and experienced losses at -100 bph. The majority of cases have been fault related and all were managed by pumping fiberous LCM pills. Good drilling practices to limit ECD's and surge pressures should be a standard. To be prepared for potential lost circulation, a copy of the 'Recommended Lost Circulation Procedures' and the 'Lost Circulation Flow Chart' will be sent to the rig prior to drilling out in the 6-%" production interval. ~ Kick Tolerance: The kick tolerance for the 6-%" open hole section would be an infinite influx assuming a kick from the Ivishak at -17,908' MD. This is a worst case scenario based on an 8.0 ppg pore pressure gradient, a fracture gradient of 9.7 ppg at the 7" window (14,150' MD), and 8.4+ ppg mud in the hole. .~.~.~mff:'».,'fØm. Job 9: Install 4Y2" Production Liner Hazards and Contingencies » An entire slotted liner may replace the Bonzai liner if water saturations within the fault block are lower then 30% and no losses are encountered while drilling the horizontal section. » Differential sticking could be a problem over this long horizontal section. Minimize the time the pipe is left stationary while running the liner. » Avoid high surge pressures with controlled running speeds and by breaking circulation slowly. High surge pressures could lead to losses. » Ensure the liner top packer is set prior to POOH. This may require going through the setting process twice. Slack off with rotation to the maximum allowable down weight, as per Baker representative. ~~~. .~.:mw.~.~ Job 12: Run Completion Hazards and Contingencies » Diesel will be used to freeze protect the well. 0.1 psia at 100° F.

Identify hazards in a pre move meeting, and take every precaution to ensure good communication prior to beginning the rig move. Use spotters when moving the rig. 7 Drillina Hazards an~ Continaencies Greater Prudhoe Bay W.38L 1 Permit '~) POST THIS NOTICE IN THE DOGHOUSE I. Well Control A. The Ivishak in this fault block is expected to be normal pressured at 8.0 ppg EMW. This pressure is estimated based on offset well pressures and material balance. II. Lost Circulation A. Lost circulation is unlikely. B. W Pad has a history of lost circulation events while drilling in the reservoir section and normally occur when crossing faults. Four expected fault crossings have been identified for this hole section. Throws on these faults are small (10 to 25'), however the risk of encountering losses at these faults is considered to be low risk (10-200/0). III. Kick Tolerance/Integrity Testing A. The 7" casing was fully cemented with 15.8 Ib/gal tail cement above the liner top packer @ -13,890' MO during the original drill and complete of the well in June 1988. B. The Kick Tolerance for the production hole section is infinite with 8.5 ppg mud, 9.7 ggp FIT, and an 8.0 ppg pore pressure. This FIT should prove up adequate formation strength for expected ECO's. C. Integrity Testing Test Point 7-in window Test Depth 20-ft minimum from the 7 -in window Test type FIT EMW (lb/Qal) 9.7 minimum IV. Stuck Pipe A. We do not expect stuck pipe. B. There could be slight differential sticking issues within the reservoir. Centralizers will be run to mitigate. V. Hydrogen Sulfide A. W Pad is not designated as an H2S site, however Standard Operating Procedures for H2S precautions should be followed at all times. Recent H2S data from the pad is as follows: B. Adjacent producers at Surface: a. W -39 less than 10 ppm b. W -37 less than 10 ppm C. Adjacent producers at TO: a. Z-18 10 ppm b. W-09 10 ppm D. The maximum level of H2S recorded on the pad to date was less than 20 ppm. VI. Faults A. The planned directional trajectory crosses four faults.
