At 09:52, GC3 started flaring because CGF booster compressors 1801, 1802, and 1857 shutdown. At 09:56, the flare relief valve at GC1 opened. Booster 1802 shutdown due to an exhaust gas temperature problem. Then, booster 1801 shutdown because of vibration problems when 1802 shutdown. Then, booster 1857 shutdown because of a fuel control problem. The WOA immediately started reducing productionrates and shutin 1141 MMSCF. The EOA immediately started reducing production and shut in 1000 MMSCF. This gas cut was enough to lower the gas transit header pressure to stop flaring. GCl flared a total of 6,433 MSCF for 59 minutes, and GC3 flared a total of 7,697 MSCF for 1 hr, 8 minutes. Due to the significant amount of production (approximately 60 wells) that had to be shutin in order to reduce the pressure enough to close the flare relief valve, the flaring event at GC3 lasted over 1 hr. Because of the gas piping hydraulics, the pressure at GCl was reduced sooner and they were able to stop flaring in just under 1 hr. Please don't hesitate to call me with any questions.

Sk-18 IP compressor K-107 shut down because of a problem associated with the newly installed discharge valve malfunction. Action Taken to Stop Flaring: 1. This problem was actually discovered during a plant restart operation. K-107 was started as normal during this plant re-start, and a problem was discovered as the plant rate was brought up, and after several hours of trouble shooting effort, Le., checking for valves in wrong position, cooler bay hydrates, etc, the problem was isolated to a newly installed discharge valve which was inadvertently installed in the closed position (confirmed by temperature differential and X-ray readings). A plan was formulated and valve reps, as well as local maintenance techs, where used to remove the actuator and re-position it so that the discharge could then function properly. During this process, we sorted highest GOR wells flowing to GC-1 and reduced gas rate through plant to minimize gas flaring. Valve actuator was repositioned, allowing valve to fully open, K107 began to move gas and flaring stopped.

The test was to determine if the flare is actually capable of operating at its design conditions to ensure safe operations. The test started at 08:49 and lasted until 10:03 and a total volume of 57,500 MSCF was flared.
