To: Winton Aubert - AOGCC Date: December 21, 2004 From: Ken Allen - BPXA GPB Rotary Drilling Subject: E-37 Application for Sundry Approval - P&A for Sidetrack Operations Approval is requested for the proposed P&A of PBU well E-37. This conventional well is currently shut-in due to multiple tubing leaks allowing communication between the tubing and inner annulus. The holes were verified by a Kinely caliper. The wellbore is providing no production or value to the field as it currently sits. Well E-37 was first completed as a horizontal well in August of 1995 with 679 ft of perforations. The perforation intervals in the range of 10,750-11 ,850' were shot targeting Zone 1 A. The perforations that were shot in the range of 12,010-12,389' targeted Zone 1 B. The original production rates for the well were 3500 bopd and 5.5 mmscf of gas per day. The oil rate began a steady decline while the gas rate started a steady increase from the day the well came on production. This trend continued until March of 1996 when an IBP was placed 11,920'. This plug shut off the Zone 1 B perforation intervals, 12,010-12,200' and 12,230-12,389'. The plug effectively shut in the major gas producing intervals of the well with minimal oil rate losses. The resultant changes in oil rate and gas rate were 1100 bopd down to -900 bopd and 30 mmscfd down to 2.5 mmscfd. The oil rate stayed around 900 bopd while the gas rate increased to 15 mmscfd in early 1998. In February of 1998 the oil rate and the gas rate $aw dramatic increases. The increase in gas rate caused the well to go to marginal GOR and led to multiple shut-ins. It was determined that the IBP had become unseated and was reset in mid 1998. The newly reset IBP stabilized production with oil rates at 800 bopd and a gas rate of -12 mmscfd. The production rates showed consistent production for three months before returning to the decline curves that were seen before the IBP reset. During mid 2000 the well reached marginal GOR rates and an oil rate of 750 bopd. This led the well to be shut in and an RST Log to be run. The Spinner Log indicated gas penetration from the two lowest perforation intervals in Zone 1A, 11,650-11,700' and 11,790-11,850'. A new IBP was set above these perforation intervals to stop their production. The new IBP lowered the oil and gas rates to 400 bopd and 5 mmscfd, respectively. The gas rate resumed the increasing rates that were expected while the oil rates remained constant until mid 2002. At this time a set of add-perfs were shot targeting 40' of Zone 1 Band 35' of Zone 1 A. The initial oil rates jumped to 3500 bopd but quickly declined to around 300 bopd. The gas rates climbed to and remained at 25 mmscfd. In the early part of 2003 E-37 was used to supply Poor Boy Gas Lift to well E-27A. Therefore E- 37 was allowed to produce at rates that exceeded marginal GOR with oil rates around 300 bopd. In November of 2003 E-37 developed TxlA communication, which led to numerous failed pressure tests. A caliper was run on 4/212004 that showed the tubing to be in terrible shape with 60 joints with 40% or greater wall penetration E-37 Application for Sundry ) ) Well E-37 currently has tubing by inner annulus communication via several corrosion holes in the tubing indicated on the caliper log. The 7-5/8" casing has been pressure tested via a combo tubing by inner annulus pressure test on 4/25/04 to 3500 psi. The outer annulus was successfully pressure tested at 2000 psi on 4/25/04. The proposed E-37 A well is located in the Southwestern portion of E Pad. The well plan is a horizontal penetration of Zone 1 A and 1 B sands that exits the parent E-37 well near the base of Zone 3 by milling a 6-3/4" window in current 7-5/8" casing. The 6-1/8" wellbore then turns to the west and lands at -8945 ft SSTVD in Zone 1 A. The planned well then runs horizontally to the west in a narrow corridor between faults before toeing up into Zone 1 B sands over the last 400 feet of the well. A solid 4-1/2" liner will be cemented in place throughout the production interval. The E-37A sidetrack is currently scheduled for Nabors 7ES beginning around 1/05/04, after completing the 0-06A rig work over. The pre-rig work for this sidetrack will be priority scheduled immediately after the Application for Sundry is approved. Pre-Ria Operations: 1. Bleed OA, IA and tubing pressures to zero. Test the IC (7-5/8") pack-off to 3500 psi, test the tubing pack-off to 5000 psi. Function all lOS, repair or replace as necessary. 2. MIT the OA to 2000 psi for 30 minutes.

Commission Anchorage On October 28, 1998 you requested an update from Shared Service Drilling regarding Annular' DispOsal Records from July 25, 1995 through preSent time. We compared your list with our records and are able to. provide you with the following data: · Individual Annular Disposal Logs from the ssD database which coincide with the approved wells on your attached AOGCC Annular Log. The.SSD records are provided to yoU in the same order as listed on your log. · There were some wells on your list which were not injected into. These wells are identified as follows: · Endicott wells 1-03/P-16, 1,65/N-25, 1-59/0-24 · EXploration well Pete's Wicked #1 · Milne Point wells E-22, E-23, F-01, L-16, J-19, L-25, F-30, .L-21, K-38, NMP #1 & #2, K-05, K-02, 1-1-07, K-25, K-37, E-17, F-21, K-30, K-34, K-21i, F-66, K-06, K-54, K-33, F-49i, K-18 · PBU Wells E-38, 18-34, 15-42, S-29A, 15-46, B-36, 15-43, 11-38 · The reason many of these annuli were not used is because the waste materials generated from these wells were injected into other approved annuli. Hopefully the injection logs submitted with this letter will clarify this. In addition, please note that our records show: · The wells listed above in italics were permitted but not used for annular 'disposal. · The wells listed above in BOLD were not Permitted for annular disposal. Wells drilled after June 6, 1996 were required by SSD procedure to be permitted with a Sundry Approval (10-403) form. Our records show that no Sundry Approval for Annular Disposal was filed for these wells. Wells drilled between July 25, 1995 and June 6, 1996 were automatically approved for annular disposal with the Permit to Drill. · We also provide you with a cumulative report from our database of records from July 25, 1995 through the present. From those records, we show the following wells not listed on your report were used for annular dispOsal: .. ,Annular Disposal Letter .'. 12/14/98 · Endicott wells 1-23/O-15, 1-61/Q-20, 2-40/S-22 Exploration well Sourdoueh #3 - Milne Point wells F-06, H-05, B-06, J- 13, L-24 - ~- ~} ~S-~q ~ t ~'loB .

As discussed'this morning we propose setting three plugs in this well as detailed in the attached form. This will allow us to retain the wellbore for potential future sidetrack or service well use. We would like to keep the well's 9-5/8" x 7" annulus available for the injection of liquid 'wastes. There are .no other well annulii on this pad for injection. The annulus for MPB-24 was approved for injection as part of the permit dated 25 January 1996. The annulus will be freeze protected before moving the rig. Thank you for your help in this matter. Please call me if I maY be of any assistance.

The BOP test was started at 050~ hrs and lasted approximately four hours. I had been on a previous BOP test on Nabors 18-E and could not witness the complete test on this dg due to fatigue. I witnessed the test on the stack and choke manifold with the exception of the annular preventer. Ali equipment functioned and held properly although a leak devolped in the choke line that required a replacement of the APl dng. The dg appeared to be in good shape and the crew performed well dudng the test. The Methane and H2S detectors were tested and although passed were due for calibration. The area surrounding the dg was clean and orderly providing good access to the dg. SUMMARY: I witnessed the weekly BOP test on Nabors dg #28-E ddlling BPX well #E-37. Test time 4 hours, 1 failure.
