In an effort to clean up database information for this well, a request was made with the. Commission to evaluate some options that would most effectively accomplish this data cleanup. Please refer to the attached document from Mr. Steve Davies that explains the wellbore status. Also attached is the current wellbore diagram. BP has reviewed and agrees with this path forward to correct database information for this set of wellbores. It is our understanding from Mr. Steve McMains that this change will be in effect by the end of the month. And finally, just to be clear, when BP prepares to drill the next sidetrack a new Application for Sundry Approval and Permit to Drill will be submitted. That sidetrack will be named 02-39C (50-029-20721-03-00). Sincerely, Cf ud-ia <~-'. Rico Fernand-ez Petroleum Engineer Gravity Drainage Team -Prudhoe Bay BP Exploration (Alaska) Inc.

The goal is to make needed changes and to adequately document those changes to provide a clear record. Three permits to drill have been approved. by the Commission for these wellbores: PBU 2-39 {PTD 1961820, API 50-029-22721-00) PBU 2-39L1 (PTD 1971100, API 50-029-22721-60) PBU 2-39A (PTD 2080500, API 50-029-22721-01) A brief operations summary for each wellbore will help explain the reasoning for the changes being applied to the Commission's well and production records. PBU 2-39 (PTD 1961820. API 50-029-22721-00) The original wellbore, PBU 2-39 (PTD 1961820, API 50-029-22721-00), spud on December 8, 1996 and reached a total depth of 12,450' measured depth on December 29, 1996. The well was perforated across seven intervals extending from 10,630' to 12,300' measured depth (MD), placed on regular production from January 1997 through April 1997. During May 1997, the well shut in because of low production volumes (for April, the well averaged 54.7 BOPD over 28 producing days). PBU 2-39L1 (PTD 1971100. API 50-029-22721-60) On June 13, 1997, the Commission approved a permit to drill for the PBU 2-39L1 lateral wellbore (PTD 1971100, API 50-029-22721-60}. The operator's intent was to drill a horizontal, lateral wellbore about 1,800 measured feet in length using a "Multi Lateral Access Sub" in the existing 4-112 inch horizontal liner and then run a 2-7/8 inch slotted liner. On July 2, 1997, a window was milled through the 4-1/2 inch liner from 10,714' to 10,719' MD and the new lateral wellbore was drilled to 11,973' MD on July 8, 1997. According to the operations summary, the reservoir rocks encquntered were shaley, so on July 8, 1997 anopen-hole sidetrack was attempted from 11,320' to 11,332' MD, but the effort was not successful. On July 9, 1997, a second open-hole sidetrack was drilled from 11,335' to 11,350' MD, but when the operator tripped the bottom-hole assembly to the window, the assembly became stuck. All fishing attempts were unsuccessful, so on July 11, 1997 the operator pumped 15 barrels of Class G cement to plug back the lateral as well as the original wellbore. Hard cement was tagged at 10,362' MD on July 12, 1997, so the original and lateral wellbores were effectively plugged and abandoned as of, when a new window was milled through the 7-inch casing. • After plugging and abandonment of the original wellbore and the attempted lateral, all subsequent re-drill operations should have been conducted under a new permit to drill and a new well name (PBU 2-39A) and a new API number (50-029-22721-01), but this did not occur, and the operations continued under PTD 1971100. On July 12, 1997, a pilot hole was milled through the cement plug to 10,410' 1VID, and on July 13, 1997, a window was milled through the existing 7-inch casing from 10,411' to 10,415' NID, and a new wellbore was drilled to 10,600' NID. Unfortunately, directional survey data indicated this wellbore had merely progressed alongside the existing casing, so it was plugged back with cement to 10,362' NID. On July 15, 1997, another window was milled through the casing at 10,336' NID, and a horizontal wellbore was drilled. This wellbore reached a total depth 12,309' NID on July 24, 1997. A 2-718 inch line was run to 11,840' NID, where it stopped. Seventeen barrels of Class G cement were used to set the liner from 9,277' to 11,840' MD, and it was perforated across five intervals between 10,679' and 11,780' 1VID on July 26, 1997. The well was put on regular production in August 1997, which continued until December 2007 when the well was shut in, apparently due to its low rate of production. All regular production between August 1997 and December 2007 was recorded against PBU 2-39L1 (API 50-029-22721-60). PBU 2-39A (PTD 2080500. API 50.029-22721-O1) On April 17, 2008, the Commission approved a permit to drill for a re-drill of PBU 2-39. This re-drill was named PBU 2-39A, and its assigned API number was 50-029-22721-O1. At present, this re-drill is not on the operator's drilling schedule, so the permit will expire in Apri12010. Well Name. PTD Number and API Number Changes In January 2010, the operator, BP Exploration (Alaska) Inc., contacted the Commission about correcting inconsistencies with the names and API numbers of the various existing and proposed PBU 2-39 wellbores, and to properly assign production. The Commission's protocol is to assign the combined production from a well and its laterals to the main wellbore. Production is only assigned to a lateral if that lateral produces through a separate tubing string. Production has been erroneously assigned to PBU 2- 39L1 in violation of this protocol, so correction is needed. The following changes to wellbore names and API numbers will be made to clarify the operator's and the Commission's well history and production databases. 1. The original well drilled between December 8 and December 29, 1996 will continue to be named PBU 2-39 (PTD 1961820, API 50-029-22721-00). All regular production occurring prior to July 13, 1997 will be assigned to this well and API number. . i • 2. The wellbore drilled from 10,714' to 11,973' MD between July 2 and July 8, 1997 will be re-named PBU 2-39L1, with a PTD number of 1971101 and an API number of 50-029-22721-60. 3. The failed open-hole sidetrack wellbore drilled from 11,320' to 11,332' MD on July 8, 1997 will be renamed PBU 2-39L1PB1 and any well lag, directional survey, sample or analytical records for this drilled interval will be assigned to PTD 1971101. with an API number of 50-029-22721-70. 4. The open-hale sidetrack wellbore drilled from 11,335' to 11,350' NID on July 9, 1997 will be renamed PBU 2-39L1PB2 and any well log, directional survey, sample or analytical records for this drilled interval will be assigned to PTD 1971101 with an API number of 50-029-22721-71. The original well PBU 2-39 and subsequent wellbores PBU 2-39 L 1, PBU 2- 39L1PB1, and PBU 2-39L1PB2 were all plugged by the cementing operations conducted on July 11, 1997. The abandonment date for these wellbores is July 13, 1997, when a new window was milled through the 7-inch casing at 10,411' MD. 6. The unsuccessful re-drill wellbore that was drilled from 10,411' to 10,600' MD and subsequently cemented on July 13 and July 14, 1997 will be named PBU 2- 39APB 1 and any well log, directional survey, sample or analytical records for this drilled interval will be assigned to PTD 1971101 with an API number of 50-029- 22721-72. 7. The successful re-drill from 10,336' NID to 12,309' MD conducted between July 15 and July 24, 1997 will be named PBU 2-39A and all records for this wellbore will be assigned to PTD 1971100 and the API number 50-029-22721-01. 8. All regular production occurring on or after July 13, 1997 will be assigned to PTD 1971100 and the API number 50-029-22721-01. 9. All printed records for the wellbores assigned to PTD numbers 1971100 and 1971101 will be maintained in the Commission's well history file folder number 1971100. 10. The wellbore name for Permit to Dri112080500, which was approved by the Commission on April 17, 2008, will be revised to be PBU 2-39B, and the API number will be changed to SO-029-22721-02. ~. i~ ~v Steve Davies Sr. Petroleum Geologist January 6, 2010 ~ t_ ~ -~ SARAH PALIN, GOVERNOR ~-75~ OIZ AID ~s 333 W. 7th AVENUE, SUITE 100 COI~TSERQA7'IO1~T COMbIISSIOI~T ANCHORAGE, ALASKA 99501-3539 PHONE (907) 279-1433 FAX (907) 276-7542 Greg Sarber CT Drilling Engineer BP Exploration Alaska Inc.
