ITEM 1a: Classification of Service Wells: Gas Injection, Water Injection, Water-Alternating-Gas Injection, Salt Water Disposal, Water Supply for Injection, Observation, or Other. Multiple completion is defined as a well producing from more than one pool with production from each pool completely segregated. Each segregated pool is a completion. ITEM 4b: TPI (Top of Producing Interval). ITEM 8: The Kelly Bushing elevation in feet above mean low low water. Use same as reference for depth measurements given in other spaces on this form and in any attachments. ITEM 13: The API number reported to AOGCC must be 14 digits (ex: 50-029-20123-00-00). ITEM 20: True vertical thickness. ITEM 22: Attached supplemental records for this well should show the details of any multiple stage cementing and the location of the cementing tool. ITEM 23: If this well is completed for separate production from more than one interval (multiple completion), so state in item 1, and in item 23 show the producing intervals for only the Interval reported in item 26. (Submit a separate form for each additional interval to be separately produced, showing the data pertinent to such Interval).

Holt, CTD Engineer Date: November 3, 2005 Re: Prep Prudhoe 15-48A for CTD sidetrack Sundry approval is requested to prepare 15-48A for a sidetrack. 15-48A was a horizontal sidetrack. This well had tubing x IA communication that was remedied with tubing patches. Adperfs were attempted with no , successful long-term production increase. 15-48A has been on cycle since mid 2004, cycle behaviour was poor with minimal on-time. The well has remained a cycle well since September 2005, when the patches were pulled in preparation for the CTD sidetrack. The sidetrack, 15-48B, is scheduled to be drilled by Nordic 1 during the second week of November. The plan calls for running a Baker 4-1/2" monobore packer retrievable whipstock for an exit into Zone 1A. 15-48B will target Zone 1A production. The following describes work planned and is submitted as an attachment to Form 10-403. A schematic diagram of the proposed sidetrack is attached for reference. f Pre-RiS! Work 1.

The sidetrack, 15-48A, will exit out of the existing horizontal 4 Y2" liner from a whipstock at 9870'md and target Zone lA reserves. The existing 4 Y2" liner perfs will be abandoned with a CIBP. The following describes the planned sidetrack. A schematic diagram of the proposed sidetrack is attached for reference. Pre CTD Summary (phase 1, planned start date 01/14/03) 1) Slickline -Drift tubing. 2) Service Coil - FCO wellbore to 10100'. Drift tubing and liner to 10050' with dummy whipstock. Set CIBP at 10050' md. Set 4 Y2" whipstock at 9870'. Form 10-403 already submitted. CTD Sidetrack Summary (phase 2, estimated spud date 02/05/03) 1) MIRV CTD rig. 2) Set 4 Y2" whipstock at 9870' if service coil was unable to. 3) Mill window out of 4 Y2" liner from whipstock at 9870'. 4) Drill 3.75" open hole sidetrack to ,....,11680' TD with MWD/gamma ray. 5) Run 3 3/16" x 2 7/8" liner, cement. 6) Run liner top packer. 7) Perforate and freeze protect. 8) RDMO Mud Program: · Phase 1: 8.4 ppg seawater · Phase 2: 8.5 ppg used Flo Pro for milling, new Flo Pro for drilling. Disposal: · All drilling and completion fluids and all other Class II wastes will go to Grind & Inject. · All Class I wastes will go to Pad 3 for disposal. Casing Program: / · A 3 3/16" x 2 7/8" solid cemented liner completion from 9400' (8865'TVDss) to TD at 11680'. The liner cement volume is planned to be ,...., 16 bbls of 15.8 ppg class G. Well Control: · BOP diagram is attached. · Pipe rams, blind rams and the CT pack off will be pressure tested to 400 psi and to 3500 psi. ./ · The annular preventer will be tested to 400 psi and 2500 psi. ) ) Directional · See attached directional plan. Max. planned hole angle is 89 deg in the new horizontal section. · Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. Logging · MWD Gamma Ray log will be run over all of the open hole section. · A CNL/GR/CCL cased hole log is optional after the liner has been run and cemented. Hazards · Drillsite 15 is not an H2S pad. Maximum recorded on the pad was 33 ppm from well 15-44. · No major fault crossing are anticipated so lost circulation risk is considered low. Reservoir Pressure Res. press. is estimated to be 3300 psi at 8800'ss (7.2 ppg EMW). Max. surface pressure with gas (0.10 psi/ft) to surface is 2415 psi. TREE ~ WELLHEAD = ACTUA TOR = KB. ELE\! = BF.
