Both events resulted from problems with GC1 process automation. The first event began at 22:35 on February 27 and lasted for 3 hours and 13 minutes. Total volume for this event was 4,979 MSFC. The second event began at 22:02 on March 2 and lasted for 2 hours 19 minutes, this event was closely followed with a full plant shut down that caused a 1 hour and 52 minute flare event. Total volume for the second event series was 5,055 MSCF. After the first event, the process automation techs changed out a bad power supply on an I/O processor. The second event resulted in a change out of a data highway that was associated with the previously worked on I/O processor. /An extended flare event is in progress at G02. The event began at 0700 ✓ on March 2 when GC2 was shut down due to a leak in the oil transit line. 2 MMSCFD of stripping gas and water tank purge gas is being maintained to keep the plant warm. We intend to maintain this condition until the plant can be restarted. Likely duration of the shut down is unknown at this time. If you require additional information, please don't hesitate to call me.

The event began at midnight on April 2 when GC2 production was initially restarted. We did not have enough rate coming into the plant to keep the LP compressor running so we flared the gas off the LP vessels and added assist gas to prevent excess emissions. This problem persisted intermittently over the next several days until we had enough rate on to generate sufficient stock tank vapors for the LP compressor to stay loaded. The event lasted a total of 63 hours. Total volume flared was 26,600 MSCF. If you require additional information, please don't hesitate to call me.

Jim Regg John Norman wrote Thank you Jim James Regg wrote: I. Date /time of release • April 6: estimated 8 pm 2. Volume of gas released - reports of 12,000 to 14.000 cubic feet: under investigation by BP 3. Apparent cause of release - external corrosion on gas lift line exiting gas lift manifold budding (commonly referred to as gas oft skid) 4. Effect on safety /environment - dry gas used for gas lift so no liquids (no environmental impact): safety implications are dependent on better understanding of leak location Uf leak point is open air as appears from what was described. it is unlikely the release would result in explosive concentration of gas) Additional Details Following is what eff Jones teamed from contacting GC -2 personnel. The release occurred on line supplying gas lift gas to Well R -19, well was shut in at time so gas was "sucked" in line at pressure near 2000 psi: effect of hole in line was to depressure - not an instantaneous release. Electrician heard the leak but could not locate it - Operator and Electrician subsequently located leak Specific location of leak is a bit sketchy from Jeffs explanation but appears it occurred on S.riser down -comer pipe after gas lift line exits manifold building. (Attached picture is for illustration purposes only, shows lines as they enter and exit the manifold building - photo is actually the Dnllsite 14 manifold building - a 2005 event) Check valve on gas Idl line held, llowbne safety valve on skid closed as it should. Cause of release appears to be external corrosion. Incident is under investigation by BP. BP apparently made a press release about this event - it sure would be nice if they would copy in when they feel it necessary to make press releases (even though the volume is Ices than our reporting threshold). Appears to be another failure that is a direct result of aging infrastructure: leak location could be an am that does not receive routine inspectioniassessmem coverage by BP operating personnel. 1 have also left a message with one of BPs release reporting coordinator but have not received a call back as yet Jim Regg John Norman wrote Jim -Wall Street Journal is apparently reporting Dent there was an uncontrolled release of natural pis last week from • HP line.

She asked if we recieved notice from BP of a 14,000 cubic foot gas release from a line at GC -2 that allegedly occurred on April 6. I quoted her our regulatory requirements for notification of uncontrolled releases (20 AAC 25.205) and clarified that we did not get a notice from BP (and would not expect one) since it was below the established treshold.

She asked if we recieved notice from BP of a 14,000 cubic foot gas release from a line at GC -2 that allegedly occurred on April 6. I quoted her our regulatory requirements for notification of uncontrolled releases (20 AAC 25.205) and clarified that we did not get a notice from BP (and would not expect one) since it was below the established treshold. I also told her that the volume should be included on the gas disposition report that we will receive from BP in May 2006. She took my name and title (Petroleum Engineer); I may be quoted.

Charles Scheve was present on rig during the incident. Incident was reported to Winton Aubert on 7/17/2006 by Scheve, then confirmed by D. Reem, BP, on the same date. Winton Aubert verbally reported the incident to Dan Seamount and Cathy Foerster on 7/17/2006. Well was circulated off bottom. A two -way check valve (TWC) was installed in the tubing hanger. A regular BOPE test was underway, being witnessed by Scheve and rig supervisory personnel. Well pressure (approx. 100 psi) ejected the TWC from the well. Rotary bushings were displaced by the event. A rig worker was struck by a piece of equipment, sustained a broken leg, and was hospitalized. The well initially flowed then was killed without further incident. Subsequently the tubing hanger threads were found to be worn. BP is investigating, will determine the root cause, etc., and report to the AOGCC. BP's investigation still underway as of 7/24/2006.

The well has collapsed tubing at roughly 3900' MD. The tubing had been cut above the collapse and the well killed from there. A two way check had been set and the BOPs nippled up prior to my arrival. The pressure testing of the BOPs and choke manifold was completed without incident, all BOPs were opened and the test was joint lowered in the stack. The co. man, toolpusher, driller and I went downstairs to the accumulator unit to preform the draw down test. As we passed by the cellar area fluid was observed draining off the the rig floor, upon returning the floor we found one hand laying next to the rotary table (obviously injured) and both rotary bushings out of place. I looked down the hole and noted substantial flow, I then assisted removing the test joint and shutting the well in. Initial shut in tubing pressure was 70 psi and built to 150 psi over time. Apparently gas and oil had migrated to the surface from below the cut in the tubing and pressured up below the two way check blowing it out of the profile. After the well was killed the two way check was found laying loose on top of the tubing hanger. An inspection of the hanger revealed partially missing threads in the back pressure valve profile. 1 of 1 7/20/2006 10:17 AM 1. Facility Number 0290000032 2. Faddy Name PBU GC 2 3. Field PBU - WOA 4.

The Gas Disposition Facilities at PBU had excessive flaring for the 2 months because of the field being shut down. A determination or hearing is being considered to determine if this excessive flaring of gas is a waste of resources for each month. Currently the agency has entered into the Gas Disposition database the data reported by the operator until AOGCC makes a determination of the excessive gas flared. At this time, the agency has not made a determination as to the status for the gas flared. Once a determination or hearing is completed the signed reports will be inserted in place of the current report. The database will be revised and procedures handled properly to correct this gas disposition excessive tlaring event. This page will be entered into each Gas Disposition Facility folder for the 2 months of excessive flaring until this situation is corrected. This page will be removed along with the duplicate reports when the final determination is made. 1. Facility 0290000032 12. GC 2 PEW WOA I Dpeab r Is.

IP compressor K207 experienced a seal leak on Aug 19 and requires a new seal. The spare IP machine (K208) has a short in the motor, requiring the motor to be replaced and therefore is unavailable at this time. Due to the current circumstances at GPB, we have determined that leaving the plant partially running during the K207 maintenance is the most prudent course of action at this time. We have taken the following actions to minimize the total flare volume: 1) shut in all HP production to reduce 2nd stage gas volume 2) shut in produced water sweep gas to reduce 3rd stage gas volumes 3) added overhaul resources to ensure 24 hour per day maintenance on K207 4) leaving LPS production on line to reduce restart duration -50 - 60 mbd of oil is required to provide enough 2nd and 3rd stage gas to load up the IP and LP machines LPS production is predominately gas lifted and takes more time to kick these wells off Shutting in LPS production will require restarting K7000 and K7001 (the copus starting motor sends gas to flare) We are anticipating completion of the work and K207 restart late Tuesday - early Wednesday, Aug 23. We will send you a follow up note with total duration and total flared volume once K207 is back on line and loaded. 8/21/2006 7•5S AA ')C2 Flariog 2 of 2 bp Exploration AK, Inc (907) 659 -4472 8/21/2006 7:55 AN GC2'Flaring 1 of 1 To: Steve McMains, AOGCC steve_mcmains @admin,state.ak.us 907- 793 -1241, fax 907- 276 -7542 Subject: GC2 Flaring From: "GPB, Optimization Engr" <GPBOptimizationEngr®BP.com> Date: Tue, 29 Aug 2006 10:47:46 -0800 CC: "GPB, Envtrott <GPBEniiironTl®BP..cira "GPB, F ►viron A Advisor wee <OPDEdvuo id ireatw $ !' � <Gary,Benson.'J : P L'onp,Meiffac An <JimpP�� 'cgibBc'Iotl1BP.com >,.'Iftitz; John""] Plant Enginepr,;cOPBGC2PlantEng t CPBPs d€tpf BP.co ` From: Dwight Warner for Hal Tucker /Mike Bolkovatz, Prod Optimization Team Leader (907- 659 -5566) The extended flaring event reported to you on August 20th ended when the IP compressor K -207 repair work was completed kite on Aug 26th.

Mike From: GPB, Prod Opt TL Sent: Saturday, October 07, 2006 5:22 PM To: Benson, Gary A; 'Cesar Rodgers' Subject: RE: WOA Sept flare report problems Cesar, Thanks, Hal From: Benson, Gary A Sent: Tuesday, October 03, 2006 4:02 PM Gary, I looked at the GC2 operator log book for the missing GC2 flare events (9/26 and 9/28). The 9417 volume for 9/26 appears to be correct. Additionally, this was accumulated during a significant portion of the day (several hours) due to depressuring J -pad and using assist gas to keep the flare clean. The 1184 volume reported in the flare database for 9/28 looks to be valid. That value should represent the volume flared due to depressuring Q -pad. I propose changing the production accounting value to 1184. I talked to Einar Heppner (GC2 CCR operator on 9/26) and he says he entered the event in the web database. Can you please look through he database to see if there was an error in the report that may have caused it to get "filed" somewhere that the database doesn't recognize as "GC2 on 9/26 "? I oft 10/27/2006 9:07 AM FW: WOA Sept flare report problems To: GPB, Prod Opt TL Subject: WOA Sept flare report problems Importance: High Hal or Mike, I'm reconciling the Setember WOA OMAR/SCADA flare volumes with the Access database flare reports and finding quite a few problems, mostly missing flare reports. I understand there was some confusion as to whether the Access or new Web -based flare application was to be used for Sept. 1 just spoke with Cesar Rogers to confirm that we are supposed to be using the old Access database until the end of October. These are the problems with WOA flaring 1 see: GC -1: 9/9 OMAR/SCADA flare meter vol of 1,459 mcf but no flare report in database 9/10 OMAR/SCADA flare meter vol of 972 mcf but flare report = 486 mcf 9/24 OMAR/SCADA flare meter vol of 417 mcf but no flare report in database 9/27 OMAR/SCADA flare meter vol of 130 mcf but no flare report in database 9/29 OMAR/SCADA flare meter vol of 590 mcf but no flare report in database GC -2: 9/26 OMAR/SCADA flare meter vol of 9,417 mcf but no flare report in database 9/27 OMAR/SCADA flare meter vol of 12,991 mcf but no flare report in database 9/28 OMAR/SCADA flare meter vol of 3,296 mcf but flare report = 1,184 mcf GC -3: 9/9 OMAR/SCADA flare meter vol of 219 mcf but no flare report in database 9/27 OMAR/SCADA flare meter vol of 125 mcf but no flare report in database Any help you can give me in clearing these up would be much appreciated!
