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). 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".

In October 1999 E-28A, a new sidetrack, was put on production. E-20 is twinned with E-28A. E-28A is a full time well that produces into the Low Pressure (LP) line. E-20 produces into the High Pressure (HP) line. Because of this incompatibility, and the fact that E-28A is a much better well, E-20 cannot compete. Anyon-time E-20 had during 2000 and 2001 is due to the fact that it temporarily supplied PBGL to E-27A. E-20 has been shut-in since April 2001 to allow E-28A to produce without competition. E-20 has produced -14.49 million barrels of oil, 70.956 bcf gas, and negligible water. E-20 is a conventional, vertical well that is currently shut in due to high GOR, tubing/lA communication, and inability to compete with its twin (E-28A). E-20 has had a GSO squeeze that was successful, however because of where the GOC is picked (just 5' above the top set of perforations) and the absence of any shale barriers, a second cement squeeze would most likely be unsuccessful at shutting off the gas and lowering the GOR. Because of this, there are no viable remediation options available to this well. Since it is shut in, E- 20 adds minimal to zero value to field production. This new sidetrack would give opportunity to increase additional recovery potential within Zone 1 B/2A of the E-Pad area. To preserve future coiled tubing opportunities the well will be completed by cementing and perforating a 4%". The sidetrack is currently scheduled for Nabors rig 2ES, beginning around November 1 st, 2004, after the completion of the J-23A sidetrack and summer maintenance. The pre-rig work for this sidetrack will begin at the Well's Group earliest convenience after sundry approval.

Dear Mr. Reiley: Enclosed is the approved application for permit to drill the above referenced well. well samples and a mud log are not required. A directional survey is required. If available, a tape containing the digitized log information shall be submitted on all logs for copying except experimental logs, velocity surveys and dipmeter surveys. Many rivers in Alaska and their drainage systems have been classified as important for the spawning or migration of anadromous fish. Operations in these areas are subject to AS 16.50.870 and the regulations promulgated thereunder (Title 5, Alaska Administrative Code). Prior to commencing operations you may be contacted by the Habitat Coordinator's office, Department of Fish and C~me. Pollution of any waters of the State is prohibited by AS 46, Chapter 3, Article 7 and the regulations promulgated thereunder (Title 18, Alaska Administrative Code, Chapter 70) and by the Federal Water Pollution Control Act, as amended. Prior to Mr. R. H. Re iley Prudhoe Bay Unit E-20 -2- March 23, 1981 com~ncing operations you may be contacted by a representative of the Department of Environmenta! Conservation. To aid us in scheduling field work, we would appreciate your notifying this office within 48 hours after the well is spudded. We would also like to be notified so that a repre- sentativ~ of the commis.sion may be present to witness testing of blowout preventer equipment before surface casing shoe is dri 1 led. In the event of suspension or abandonment, please give this office adequate advance notification so that we may have a witness present. Very truly yours, ~.
