Flaring was permitted to continue while operations personnel attempted to restart the facility equipment. These start-up related flaring events have stopped now that the CGF shutdown is complete. 1) On 8/16/2014, flaring at CGF started at 01:30 and stopped at 06:00 with a volume of 15972 (MSCF). The event lasted for 270 minutes. 2) On 8/15/2014, flaring at CGF started at 00:01 and continued through midnight with a volume of 81383 (MSCF). The event lasted for 1439 minutes. 3) On 8/14/2014 flaring at CGF started at 02:45 and continued through midnight with a volume of 13731 (MSCF). The event lasted for 1275 minutes. 4) On 8/12/2014, flaring at CGF started at 04:30 and stopped at 05:05 with a volume of 255 (MSCF). The event, which lasted for 35 minutes, was due to shutdown of Compressor 1802 for planned maintenance. The event ended when depressurization of the compressor was complete. 5) On 08/10/2014, flaring at CGF started at 19:40 and stopped at 23:58 with a volume of 32410 (MSCF). The event, which lasted for 258 minutes, was due to depressurizing the WOA 60" line and 4938 Inlet Separator vessel for planned maintenance. The event ended when depressurization was completed. GC1 A flaring event also took place at GCI on 08/10/2014 due to the same planned maintenance on the WOA 60" line as flaring event #5 at CGF above. The IP and LP compressors flared during the required swap of production from the GC1 Annex to the Old Plant to perform the maintenance. The flaring stopped when the gas rate to old plant was stable. The flare event at GC1 started at 08/10/2014 19:51 and stopped at 08/10/2014 23:10 with a volume of 491 (MSCF). The event lasted for 199 minutes. FS3 Flaring events occurred at FS3 from August 12-14 while restarting the facility after a prolonged planned shutdown for maintenance. These flaring events have stopped now that maintenance is complete. 1) A flare event at FS3 starting at 08/14/2014 03:30 and stopping at 08/14/2014 03:35 with a volume of 80 (MSCF). The event lasted for 5 minutes and was due to starting the 1803 compressor. The flaring stopped when the startup sequence was complete. 2) A flare event at FS3 starting at 08/14/2014 14:22 and stopping at 08/14/2014 14:34 with a volume of 60 (MSCF). The event lasted for 12 minutes and was due to depressuring the 14D common line at DS 14 in order to isolate a well slot choke. The flaring stopped when the line was depressured to a safe energy state. 3) A flare event at FS3 starting at 08/14/2014 17:06 and stopping at 08/14/2014 17:11 with a volume of 60 (MSCF). The event lasted for 5 minutes and was due to shutting down the 1803 compressor to troubleshoot the DC LO pump run issue. The flaring stopped when the shutdown sequence was complete. 4) A flare event at FS3 starting at 08/13/2014 23:34 and stopping at 08/13/2014 24:00 with a volume of 242 (MSCF). The event lasted for 26 minutes and was due to depressuring the 14BC common line and MI line for a gas leak on the MI flange. The flaring stopped when the lines were depressured to a safe energy state. 5) A flare event at FS3 starting at 08/12/2014 14:00 and stopping at 08/12/2014 18:00 with a volume of 120 (MSCF). The event lasted for 240 minutes and was due to shutting down T\C 1803 after attempting 3 starts. Flaring stopped once shutdown was complete. 6) A flare event at FS3 starting at 08/12/2014 03:00 and stopping at 08/12/2014 09:00 with a volume of 9015 (MSCF). The event lasted for 360 minutes. Flaring occurred when the STV -IP T\C 1802 unloaded due to low gas rates. Flaring was stopped by increasing rates to load the STV/IP T/C. Please let me know if you have any questions.

The flaring initially occurred on September 2 due to low oil rates resulting in insufficient gas to the IP compressors. Intermittent flaring occurred while operations personnel worked on the compressor surge control set-up on September 4`h. A new IP compressor surge control system was installed on September 5-9 with coincident flaring as this maintenance work was conducted. On September 10`h, the IP compressors were off-line. The V-136 flare set -point was intentionally lowered on September 10-12 to minimize the volume flared by preventing LP flaring that requires the addition of assist gas to prevent black smoke. GC 1 production was reduced to minimize flaring while Operations continued to troubleshoot the problem. Transit gas pressure was reduced in an effort to provide operating conditions favorable to the IP compressor. Yesterday, a possible root cause of the problem was found in a low temperature from the crude heater. GC 1 is working on a solution to the crude heater problem and production will continue to be curtailed to reduce flaring.

The event lasted for 120 minutes, and was due to cool down of K7000 LPS compressor for planned work. A flaring event occurred at GCI starting at 11/18/2014 18:24 and stopping at 11/18/2014 23:07 with a volume of 460 (MSCF). The event lasted for 283 minutes, and was due to annex shutdown and associated flaring for depressure. A flaring event occurred at GC1 starting at 11/19/2014 09:00 and stopping at 11/19/2014 20:30 with a volume of 6580 (MSCF). The event lasted for 690 minutes. The event had a volume greater than 5000 (MSCF), and was due to trip of GILT compressor due to power load shedding s/d. Flaring stopped when power was restored and the plant restarted. A flaring event occurred at GCI starting at 11/20/2014 01:00 and stopping at 11/20/2014 06:30 with a volume of 2920 (MSCF). The event lasted for 330 minutes, and was due to backout of LP/IP compressors from transit system due to performance issues. A flaring event occurred at GC1 starting at 11/21/2014 07:00 and stopping at 11/22/2014 with a volume of 6180 (MSCF). The event lasted for 1020 minutes. The event had a volume greater than 5000 (MSCF), and was due to backout of LP/IP compressors from transit system due to performance issues. A flaring event occurred at GC2 starting at 11/17/2014 00:07 and stopping at 11/17/2014 01:30 with a volume of 231 (MSCF). The event lasted for 83 minutes, and was due to ambient -driven fluctuations in transit gas line pressure. Flaring stopped when production rates were cut. A flaring event occurred at FS1 starting at 11/19/2014 15:00 and stopping at 11/19/2014 17:45 with a volume of 974 (MSCF). The event lasted for 165 minutes, and was due to STWIP 1802 compressor shutdown to allow for testing of new STV/IP compressor 1825. A flaring event occurred at FS1 starting at 11/21/2014 08:00 and stopping at 11/21/2014 18:50 with a volume of 3611 (MSCF). The event lasted for 650 minutes, and was due to STV/IP 1802 compressor shutdown to allow for testing of new STV/IP compressor 1825.. A flaring event occurred at FS1 starting at 11/22/2014 10:25 and stopping at 11/22/2014 19:46 with a volume of 6234 (MSCF). The event lasted for 561 minutes. The event had a volume greater than 5000 (MSCF), and was due to STV/IP 1802 compressor shutdown to allow for testing of new STV/IP compressor 1825. Please let me know if you have any questions.
