Pacific Gas & Electric allowed a systemwide high-inventory OFO that had been in effect for the previous two days to expire Saturday.
CIG declared a force majeure Thursday after experiencing a failure in the system control process at Keyes South Compressor Station in the Oklahoma Panhandle. It planned to reduce Keyes South capacity from 218 MMcf/d to 200 MMcf/d, effective with Timely cycle nominations for Saturday's gas day until further notice. Although an estimate of the duration of the outage was not yet available, CIG said it anticipated the capacity cut remaining in effect through at least Monday's gas day.
Reporting completion of pump repairs at the Clay Basin storage facility compressor station and the station was fully functional, Questar said current operating conditions allowed total Clay Basin injection capabilities of 350,000 Dth/d beginning last Thursday. That was up from 325,000 Dth/d during the repair work but less than normal injection capacity of 375,000 Dth/d.
Sea Robin Pipeline, which Thursday reported being notified by operator Hess Corp. that the Sea Robin Gas Processing Plant might be able to begin providing dehydration services as early as Saturday while a 14-day total suspension of processing that began May 21 continues (see Daily GPI, May 29), said the resumption of dehydration was delayed until late Saturday or Sunday morning. The delay was due to additional time needed for maintenance completion, the pipeline said. Also, while Hess had previously said minimum sustained flow of 75 MMcf/d through the plant for the dehydration unit to run, it now must be approximately 100 MMcf/d, Sea Robin Pipeline said. "Due to the uncertainty of the actual start-up timing of the dehydration unit, the increased flow volume requirement and the uncertainty of flow volume over the weekend," it was unlikely that nominations for flow on the Saturday through Monday gas days would be scheduled.
Maintenance projects throughout June on the North Mainline will result in varying periods of capacity cuts (from an estimated base of 2,200 MMcf/d) ranging from 224 MMcf/d to 472 MMcf/d, El Paso said. The biggest reduction will occur June 16-17.
Noting an early-May posting that cited "insufficient supplies of gas" as the reason that CIG anticipates suspending operations at the Natural Buttes Processing Plant starting June 1 (see Daily GPI, May 8), the pipeline has provided further details on the implications of such a move. See the bulletin board for more information.
