The event had a volume greater than 5000 (MSCF). These events were due to LPS K7000 compressor shutdown due to high speed trip. K7001 was already down for planned maintenance, so rates were reduced to minimum rates necessary to keep piping warm until freeze protect could be complete.

The event lasted for 1260 minutes, and was due to LP compressor instability due to temperature swings. Flaring stopped when necessary process changes were made. A flaring event occurred at GC1 starting at 06/20/2014 05:08 and stopping at 06/21/2014 with a volume of 2616 (MSCF). The event lasted for 1132 minutes, and was due to low oil throughput causing insufficient LP/IP gas.

The majority of the flaring occurred due to start-up of GC2: 9/13 A flaring event occurred at GC2 starting at 09/13/2014 16:58 and stopping at 09/13/2014 17:14 with a volume of 111 (MSCF). The event lasted for 16 minutes. Flaring was due to high transit line pressures caused by CCP compressor problems due to loss of tandems. The WOA reduced production rates to stop the flaring. 9/7 A flaring event occurred at GC2 starting at 09/07/2014 07:30 and stopping at 09/07/2014 23:30 with a volume of 6000 (MSCF). The event lasted for 960 minutes. The event had a volume greater than 5000 (MSCF). Flaring was caused by ESD testing of plant and field devices. GC2 was shut down and restarted for the ESD testing. The flaring stopped when GC2 was restarted. 9/3 A flaring event occurred at GC2 starting at 09/03/2014 14:00 and stopping at 09/03/2014 22:30 with a volume of 2833 (MSCF). The event lasted for 510 minutes. Flaring occurred when the K207 IP compressor was shutdown for repairs and high vibration. Flaring stopped when the compressor was restarted. 9/2 A flaring event occurred at GC2 starting at 09/02/2014 00:01 and stopping at 09/02/2014 23:59 with a volume of 11983 (MSCF). The event lasted for 1438 minutes. The flaring occurred when the IP compressor shut down because of a problem associated with GC2 start-up. The flaring stopped as start-up problems were resolved. 9/1 A flaring event occurred at GC2 starting at 09/01/2014 06:00 and stopping at 09/01/2014 23:49 with a volume of 11878 (MSCF). The event lasted for 1069 minutes. The flaring occurred when the IP compressor shut down because of a problem associated with GC2 start-up. The flaring stopped as start-up problems were resolved.

The event lasted for 398 minutes and occurred when the Wet Gas compressor shutdown because of control/instrumentation failure associated with a faulty instrumentation. Flaring was permitted to continue while GC operations personnel attempted to restart the equipment. Flaring stopped when the compressor was restarted successfully. A flaring event occurred at GC2 starting at 12/05/2014 14:32 and stopping at 12/05/2014 17:26 with a volume of 1088 (MSCF). The event lasted for 174 minutes and occurred when the IP compressor was shut down because of a problem associated with re -start of production following plant shutdown. Flaring was permitted to continue while GC operations personnel attempted to restart the equipment. Flaring stopped when the compressor was restarted successfully. A flaring event occurred at GCI starting at 12/05/2014 14:30 and stopping at 12/05/2014 23:00 with a volume of 5050 (MSCF). The event lasted for 510 minutes. The event had a volume greater than 5000 (MSCF) and occurred when GC2 shut down causing the LPAP compressors to lose flow. Flaring stopped when GC2 started flowing oil to GC 1 and gas rate increased so that forward flow was reestablished in the LP/IP machines.
