During this upcoming event, we plan to SI most of the high pressure producing wells and cycle wells with high watercut to prevent flow line freezing. Operationally, at this time of year, we have chosen not to shut the entire plant down due to the substantial risks of freezing (potential cracked lines resulting in spills, heat for personnel safety, etc). It is expected that the repairs will last 24-48 hrs. This complies with the SOP procedure for this machine. Once we have taken the above steps to minimize flaring, the total flare rate will be roughly 2 - 2.5 MMSCFPD while the compressor is being repaired. I will follow up with an email after the work is completed detailing the actual events. Please call or email if you need.additional clarification.

The operation began at 1600 on January 6 and was completed at 0500 on January 8 when the machine was loaded up and the flare valve closed. Total duration of the flaring event was 36 hours and 55 minutes. 3,209 MSCF was flared during the event. Production was cut to minimize flaring per our procedure, with a minimal amount of HP production remaining on to prevent flowline freezing. At the 24 hour threshold, it appeared that K5500 would be restarted within the next several hours and, since the ambient temperature was still well below 0, the decision was made to leave GC3 on line. K5500 restart was delayed by 5 hours due to slide valve calibration problems. At 0424 on January 8 the first K5500 restart was unsuccessfully attempted, with the second and successful attempt occurring at 0451. K5500 was loaded up and the flare valve closed at 0455 on January 8. Please call or email if you need additional clarification.

The K5500 compressor bundle was replaced with a newly rebuilt bundle due to excessive and increasing vibrations on the old bundle. Production was cut per our procedure to minimize flaring. Assist gas was added as necessary to ensure compliance with our Title V air quality permit. Total volume flared was 2,763 MSCF, over a 33 hour and 37 minute duration. If you require additional information, please do not hesitate to call me. Hal Tucker GPB Production Optimization TL 659-4472 Lofl 5/3/2004 6:45 AM Gas Release And Venting Steve, Thanks for calling me back this morning, sorry I wasn't in the office when you called. When pressuring up our EWE Mlline yesterday to verify recent repairs, we had a stem seal leak on a shutdown valve at W-pad. We haven't finished volume calculations yet, but don't feel that the stem seal leak came anywhere near the 1 OOOmscf threshold that requires reporting under 20 MC 25.205. In order to repair the stem seal, we've begun venting the system. There is some potential that we could reach the 1 OOOmscf threshold before the venting operation is complete. Venting of the system doesn't seem to fit the category of "uncontrolled release" that requires notification, but I wanted to inform you of the work we're doing and see what your thoughts are. We are always happy to communicate with your folks and make you aware of our activities, but I would be interested in knowing whether you think this falls into the category of uncontrolled release per 20 Me 25.205. Thanks again for your time, Dave David Dawley GPB Environmental Advisor 6594789 "Lofl 4/15/200411:33 AM ..' r STATE OF ALASKA ALASKA OIL AND GAS CONSERVATION COMMISSION FACILITY REPORT OF PRODUCED GAS DISPOSITION 1.

This is a note giving you a courtesy "heads up" on the greater than one hour flare events you will be seeing in the monthly gas disposition reports prepared by the Anchorage Volume Accounting Team. * ~experienced three flare events on June 24, 25 and 26 due to K5500 ~ng down on high lube oil temperature. Temperature probes, RTD's and switches were changed out during the three days in attempts to eliminate that root cause of the shut downs. K5500 procedures were followed to minimize flaring. Total volume for the three events was 1,261 MSCF, total duration for the three events was 7 hours and 17 minutes. * FS1 experienced one extended flare event beginning at 10:00 June 17 and ending at 02:45 June 18 when the 1801 STV/IP compressor shut down due to high ambients. Several attempts were made to restart and reload the machine. Total flare volume for the event was 8,491 MSCF over 16 hours and 45 minutes. * GC2 experienced two flare events on May 30 and 31 due to PLC malfunction in the produced water section of the plant. The production cuts resulting from the water section upset caused the skid 18, IP and LP compressors to surge intermittently due to the low GC oil rate. The compressors loaded up as GC2 oil rates returned to normal. Total volume for the two events was 920 MSCF, total duration was 5 hours and 31 minutes. * CGF experienced two flare events on June 17 and 18. The first event occurred when the 1884 tandem shut down 3 times due to high ambient temperatures over a 2 hour period. Each shut down resulted in 15 minutes of flaring. This event should have been captured as three separate flaring events and should not be considered as a greater than one hour event. The second event occurred when the 1805 MI compressor shut down a recycle trip while loading the boosters. Flaring stopped when 1805 was restarted. Total duration for the 1805 event was 1 hour and 14 minutes, total volume was 8,677 MSCF. * LPC experienced one flare event on June 17 when the 1808 gas reinjection turbine shut down. Flaring stopped when 1808 was restarted. 10f2 6/28/20047:02 AM . GPB Flaring Incidents Gas was cut during the event to reduce flare volume. Total duration for the event was 1 hour and 16 minutes, total volume was 5,804 MSCF. * FS3 experienced two flare events on JUDe 17 and June 20. The first event occurred when the 1801 STV/IP compressor shut down due to high ambients and plant upsets. After three failed restart attempts, the spare machine (1802) was started, ending the flare event. Total duration for this event was 1 hour and 10 minutes, total volume was 466 MSCF. The second event occurred when the 1806 gas lift machine shut down due to instrumentation problems. 1806 was secured and depressured, ending the flare event. Total duration of the event was 6 hours of intermittent flaring totaling 685 MSCF. If you require additional information, please do not hesitate to call me.

He would like more detail to explain what happen, associated with UPS power? *GPMA Facility Oct 2000 thru Aug 2004* - Oct 2000, Dec 2001, Jan 2003 and Aug 2004 the facility had a sharp spike in the pilot-purge volume, from less than 15,000 mcf to over 40,000 mcf just for those four months. Could you provide an explanation why these sharp spike took place in pilot-purge volumes. This is the only facility that has shown these spikes for pilot-purge volumes. Steve 1 of I 10/28/2004 I :29 PM RE: Data Request To: Steve McMains, AOGCC steve mcmains@admin.state.ak.us 907-793-1241, fax 907-276-7542 From: Hal Tucker, GPB Prod Optim Team Leader, 907-659-4472 The incident in question was initiated at 0220 on 8/9/2004 when the UPS monitoring system for the LPS sections (skids 460 & 461) of GC3 "died completely". Under normal conditions, a fault in the UPS would be detected [by the monitoring system] and the plant power supply would be seamlessly failed over from UPS to CPS line power. Due to the complete failure of the UPS monitoring system the fail over did not occur and the LPS sections lost power resulting in a plant shut down. Restart of the plant began at 0600 but, wasn't successfully restarted until after 1600. During the several restart attempts it took to get K7000 and K7001 (LPS turbine/compressors) up and running at least 3 blown power supply cards had to be replaced in the turbine controls systems. Hal Tucker GPB Production Optimization Team Leader 659-4472 From: Stephen Mcmains [mailto:steve mcmains@admin.state.ak.us] Sent: Tuesday, March 29, 2005 8:04 AM To: Tucker, Hal E Cc: Jim Regg Subject: Data Request Hal, In August 2004, GC -3 had a greater than 1 hour flaring event with 66,667 mcf of gas reported vented. On the monthly report submitted to AOGCC, the event stated, "LPS compressor K-7000 and K-7001 shut down because of a problem associated with UPS power". Could you expand in depth on what is met by, "problem associated with UPS power"? I have tried several times for an explanation and haven't received an explanation yet, six months, so could you please respond by the 6th of May 2005. Thank you. Steve 10f2 3/29/2005 2: 13 PM .! ...
