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: Ifthis 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). ITEM 26: Method of Operation: Flowing, Gas Lift, Rod Pump, Hydraulic Pump, Submersible, Water Injection, Gas Injection, Shut-In, or Other (explain). ITEM 27: If no cores taken, indicate "None". ITEM 29: List all test information. If none, state "None".

Well 5-28A was completed as a Z1 CTO sidetrack in November 2001 and produced steadily until April 2002 when a Cretaceous casing and tubing leak developed. The initial leak filled the tubing with sand which prevented the Cretaceous water from damaging the Ivishak. In April 2003, a tubing patch was set to repair the tubing leak. Coiled-tubing cleaned the Cretaceous sand from the tubing and nitrogen-lifted the well to production. 5-28A produced for 3 months before developing a second tubing leak. A second tubing patch was set in September 2003 but the well was unable to produce. No sand was observed in the tubing after the second leak and the Cretaceous water likely damaged the near-wellbore formation preventing the well from flowing. The well has been shut in since 1/03 due to a TxlA annular communication and a production casing leak. A sidetrack to re-establish the well as an Ivishak Zone 1 A/1 B producer is seen as the best way to maximize the value of the wellbore. The sidetrack is currently scheduled for Nabors rig 2ES, beginning mid July 2006. The pre-rig work for this sidetrack will begin at the Well's Group earliest convenience after sundry approval.

Annular disposal has not been requested as part of the Permit to Drill application for Prudhoe Bay Unit 05-28A Blowout prevention equipment (BOPE) must be tested in accordance with 20 AAC 25 035. Sufficient notice (approximately 24 hours) must be given to allow a representative of the Commission to witness a test of BOPE installed prior to drilling new hole. Notice may be given by contacting the Commission petroleum field inspector on the North Slope pager at 659-3607.

Mud Program: . Phase 1: Seawater . Phase 2: Seawater for milling and Flo-Pro (8.6 - 8.7 ppg) for drilling Disposal: . No annular injection on this well. . 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: . 2%", L-80, solid liner will be run from 9,850'md (TOL, 8053' TVDss) toTO at approximately 12,300'md. Liner will be cemented to approximately 550' above the window with approximately 17 bbls (annular volume plus 25% excess in OH) of 15.8 ppg class G cement. Well Control: . BOP diagram is attached. . Pipe rams, blind rams and the CT pack off will be pressure tested t(jijr" ..,' . The annular preventer will be tested to 400 psi and 2,200 psi. Directional . See attached directional plan. . Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. Logging . An MWD Gamma Ray log will be run over the open hole section. . A memory CNL will be run inside the liner. Hazards . 05-28 flow stream was last sampled at 8ppm H2S in Nov 96. Drillsite 5 is not an H2S area. . The well path will cross two mapped fault either side of a graben. The fault throw associated with this structure is estimated at 10-15ft. Lost fluid circulation is not anticipated. Reservoir Pressure Reservoir pressure is e.§!jJp!~t~~~~~ø"be 3,200 psi at 8,800ss.
