On January 19 extended flaring occurred off the IP and LP compressors due to low plant oil rate. Plant oil rate was down due to level valve maintenance on D -slug catcher. The event duration was 282 minutes, with a total flared volume of 4700 MSCF. On January 21 extended flaring occurred off the LP compressors due to low plant oil rate. Plant oil rate was down to repair a PSV in the PW plant. Flare duration was 1259 minutes, with a total flared volume of 18,360 MSCF. On January 23 extended flaring occurred off the LP compressors due to low plant oil rate. Plant oil rate was reduced due to fuel gas repairs on the K7000 LPS turbine /compressor. The situation was exacerbated when L -pad shut down due to a Fire and Gas system failure and the main produced water pump shut down due to high vibration, both during phase III weather conditions. Flare duration was 1027 minutes, with a total flared volume of 17,830 MSCF. The low oil rates from the January 23 events, continued through January 27, resulting in extended flaring events during that time. 1/24 flare duration 1019 minutes, volume 9,900 MSCF 1/25 flare duration 1440 minutes, volume 12,991 MSCF 1/26 flare duration 1424 minutes, volume 12,856 MSCF 1/27 flare duration 96 minutes, volume 867 MSCF The event ended on 1/27 at 03:23 when the B- Sulzer was brought on line following completion of seal repairs Gait also had an extended flaring event during this time frame. The event was caused when K7000 LPS turbine /compressor shut down due to an instrumentation problem. GC3 shut in 14 wells, totaling 75 MMSCFD to get out flare. The event occurred on January 27, beginning at 07:56, ending at 09:16 (80 minutes). Total volume flared was 1,319 MSCF. If you require additional information, please don't hesitate to call me.

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.

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 load 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 of 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.

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 event lasted for 600 minutes. The cause was by multiple electrical and instrument problems related to problems with the UPS power system. As a result the K -5500 wet gas compressor shut down. Assist gas was added to mitigate black smoke, and water production was reduced to reduce flared volumes. K -5500 was successfully restarted and flaring ceased. An extended gas flaring event took place at GC2 starting at 10/18/2008 15:01 and stopping at 10/18/2008 15:43 with a volume of 233 (MSCF). The event was a black smoke event. This is thought to be due to a leak into the fuel gas system. Assist gas was used to stop black smoke. The leak is being troubleshooted, and a replacement valve is ordered and due for delivery imminently. Please contact me if you have any questions.
