The event had a volume greater than 5000 (MSCF) and was due to a CGF Plant Shutdown caused by an electrical issue resulting in flaring while the field responded. The event stopped when the Field reduced production rates and shut-in wells. A flaring event occurred at CGF starting at 07/06/2017 16:22 and stopping at 07/06/2017 22:23 with a volume of 430 (MSCF). The event lasted for 361 minutes and was due to a T\C 1883 shutdown caused by a problem associated with plant shutdown and electrical outage. The event stopped when 1883 T/C depressurization was completed. A flaring event occurred at CGF starting at 07/06/2017 16:22 and stopping at 07/06/2017 23:59 with a volume of 419 (MSCF). The event lasted for 457 minutes and was due to Stabilizer overhead relief caused by the plant shutdown. The event stopped when Field production was cut to lower gas production until CGF restarted. A flaring event occurred at CGF starting at 07/09/2017 09:50 and continued into 07/10/2017 23:59 with a volume of 48960 (MSCF) for 07/09/2017. The event lasted for 849 minutes and was due to restarting the CGF plant from an unplanned power outage — flaring from the top of the stabilizers while getting NGL on -spec for shipping. The event continued into 07/10/2017. A flaring event occurred at CGF starting at 07/10/2017 00:00 and stopping at 07/10/2017 08:02 with a volume of 32913 (MSCF). The event lasted for 482 minutes and was a continuation of the previous day's flaring event for restarting the CGF Plant. The event stopped when 1855 T/C was loaded and stabilized facility process and operation. A flaring event occurred at CCP starting at 07/16/2017 05:15 and stopping at 07/16/2017 08:30 with a volume of 301 (MSCF). The event lasted for 195 minutes and was due to depressurization of the NGI injection lines for the NGI saddle replacement project. The event stopped when depressurization was completed. A flaring event occurred at CGF starting at 07/21/2017 06:42 and stopping at 07/21/2017 11:07 with a volume of 32533 (MSCF). The event lasted for 265 minutes and was due to a T/C 1855 shutdown caused by a control/instrumentation failure.
