Trouble-shooting by technicians indicated parts would be required to be replaced and mare than an hour would likely elapse before machine could be restarted. 06:45 Called lrillsite Operators to shut-in 200 MMSCFD gas production. Nate that all production cuts (by shut-in at wellhead) were slowed due to Phase II weather conditions which required convoy of two or more vehicles at-a-time. • 07:30 Called Drillsite Operators to shut-in additional 20 MMSCFp gas production. • 09:20 First start attempt was unsuccessful; trouble-shooting continued. • 12:00 Called Drillsite Operators to shut-in additional 20 MMSCFD gas production. • 13:00 Second start attempt was successful. • 14:47 Compressor loading began; (shut-in) wells started to be brought back to production. • 16:05 Additional 10-minute flare event occurred due to difficulty to load compressor completely. • .
