The first event is a follow up to the flaring events at GC2 described in Dwight Warner's April 14 e -mail. GC2 continued to experience intermittent flaring from K205/K208 through April 14 and 15 until 12:13 AM on April 16 when sufficient process heat was restored to enable second and third stages to break out enough gas to allow K205/K208 to maintain forward flow. Process heat, from the turbine /compressor K7000 Waste Heat Recovery Unit, was restored once repairs to the combustion section of K7000 were completed. The damage to the combustion section was discovered during routine maintenance. During the flaring event, operations cut total field gas rate and gas rates at all 3 GC's to reduce the back pressure on K205. Additionally, process changes (decreased gas cooler temperature to increase condensate yield, and increased suction KO drum temperature to increase flashed gas) were made to increase the available gas volume to the suction of K205. These changes enabled K205 to intermittently attain forward flow and thus reduce flare volumes. Flare duration and volume [in addition to what Dwight has already reported] were 46 hours 23 minutes and 50,175 MSCF. For approximately 23 hours of that duration, flaring was intermittent. An extended event occurred at GC1 on April 19. The event was part of the turbine cool down procedure in preparation for routine water washing. The flaring event began at 1658 and ended at 1840 (102 minutes), the total volume flared was 3,188 MSCF. The third event, which occurred albs'$1 on April 19, is being reported at your request. This event had a volume of greater than 5,000 MSCF. Turbine /compressor 1804 shut down on a vibration alarm. The flaring event began at 0627 and ended at 0720 (53 minutes), the total volume flared was 6,592 MSCF. If you require additional information, please don't hesitate to call me.

The offline T/C 1855 was started, and stabilized facility process and normal operations. The flaring event began at 1810 and ended at 1842 (32 minutes), the total volume flared from meter #660 was 5036 MSCF and from meter #618 was 387 MSCF. Total volume flared from the event was 5423 MSCF. An extended event occurred at FS1 on April 30 when the LPS turbine /compressor 1804 shut down because of a problem associated with adjustment of the vibration shut down set points. The flaring event began at 1717 and ended at 1814 (57 minutes), the total volume flared from this event was 12,588 MSCF. Shortly after restarting this machine the LPS T/C 1803 shut down for an unknown reason. The flaring event began at 1817 and ended at 1847 (30 minutes), the total volume flared was 6,354 MSCF. An event at FS3 that occurred on April 21 had the total volume flared changed from 705 MSCF to 723 MSCF.

This caused all production facilities and the gas plants to shut down. Power was partial re- established at 02:13 and most of the facilities were back on shore power by 03:30. Listed below are the facilities that flared for more than an hour or total volume flared exceeded 5000 MSCF as well as the facilities that flared but did not exceed this criteria to help with month end reports. Most of the flaring carried over to 5/9/08 and since the flare reports are midnight to midnight I have provide total volumes. Also, provided extended flaring events while starting up.

On 5/12 an extended event occurred at CGF when T/C 1805 shut down due to an instrument problem. Total duration of the event was 84 minutes. Total volume flared was 12,228 MSCF. Two extended flaring events occurred at GC2 on 5/13 and 5/14. Both events were related to the full plant shut down initiated due to an inadvertent valve closure on the oil transit line. The first event began at 07:37 and ended at 23:40. Flaring from the IP and LP vessels occurred during troubleshooting and plant restart preparation. The second event began at 01:38 and ended at 11:00 when sufficient oil rate was brought on line to allow the IP /LP compressors to Toad up. Total duration and volume for the first event was 963 minutes and 16,719 MSCF. The second event had a total duration and volume of 572 minutes and 596 MSCF. An extended flaring event occurred on 5/14 at FS3 while performing safe out operations in preparation for unplanned maintenance on T/C 1801. T /C's 1801 and 1802 are the STV /IP machines for FS3 and both needed to be shut down to install blinds to enable repairs to 1801. 1801 sustained damage during the full field shut down (CPS power outage). The flaring event began on 5/14 at 09:00 and ended on 5/15 at 23:59 (39 hours), total volume flared was 14,125 MSCF. Four extended flaring events occurred at FS1 on from 5/15 through 5/17. All four events were associated with planned maintenance (water washes) on LPS T /C's 1803 and 1804. The first two events were the spin cooling to prep for the water wash and cranking during the water wash for T/C 1803. The second two events were for T/C 1804 (same activities). 1803 spin cool 120 minutes, 775 MSCF and crank 90 minutes, 572 MSCF - - -- both on 5/15 1804 spin cool 118 minutes, 658 MSCF and crank 60 minutes, 383 MSCF - - -- 5/16 spin and 5/17 crank An extended flaring event occurred on 5/18 at GC3 to depressure D -bank, 1st stage, HP separator piping to repair a small leak. The event began at 15:50 and ended at 17:45. Total duration was 115 minutes, total volume was 399 MSCF. On 5/19 an extended flaring event occurred at CGF. MI T/C 1855 was shut down and depressured to repair an oil leak. Total duration was 155 minutes, total volume was 285 MSCF. 5/20/2008 , GPB Gas Flaring Events Page 2 of 2 If you require additional information, please don't hesitate to call me.

An extended flaring event occurred at GC3 on June 28 depressuring the Y Pad LDF for safeout on the gas lift system at GC2. The flaring event began at 22:30 and ended at 23:30 (60 minutes), the total volume flared was 7,500 mscf (the first report showed a volume of 16,666 mscf). An extended flaring event occurred at GC2 on June 17 on when the plant was shut down due to SDV valve closing on the oil transit line. The extended event continued while operations /maintenance evaluated causes. The flaring event began at 03:46 and ended at 24:00 (1214 minutes). The total volume flared was 12646 mscf. An extended flaring event occurred at GC2 on June 18 while bringing up production rates following the plant shut down. The LP compressors were not able to run at low gas rates and had to be discharged to flare during start up operations. The flaring event began at 00:01 and ended at 10:30 (629 minutes), the total volume flared was 6115 mscf. If you require additional information, please don't hesitate to call me.

This was caused by a loss of electrical power to the CGF utilities section at approximately 20:58, which caused the tandems and booster compressors to shut down on high lube oil temperature. This increased the transit gas pressure, and several facilities (listed below) were forced to flare. Rate was reduced by shutting in high gas wells until CCP could handle the gas load from the field. The cause of the electrical shutdown is under investigation. CGF began coming back online at approximately 00:10, and was fully operational by approximately 09:00 on 10/15/08. GC1 at 10/14/2008 starting at 21:04 and stopping at 10/14/2008 22:02 with a volume of 7048 (MSCF). The event lasted for 58 minutes.

The Drill Site was shut down and depressured. Messages were left for the AOGCC inspector on the slope as well as the Anchorage Office at approximately 7:10 am by Mike McDaniel the Environmental TL. A hairline crack on the downstream side of the choke for well 1 -15 was the cause. The volume of gas released was 10.9 MSCF and approximately 5 gal of crude that misted in the module. The choke has been replaced and the Drill Site should be put back on production later today. In order to secure the Drill Site, the wells were shut in and the common lines were depressured through the FS1 facility. This resulted in a flaring event, starting at 05:28 and finishing at 06:19, a duration of 51 minutes. The total volume of gas flared was 787 MSCF.
