Cheyenne Plains Gas Pipeline said no problems were identified during Tuesday’s emergency shutdown test at its Cheyenne Plains Compressor Station and treating plant. It increased operationally available capacity Wednesday to 816 MMcf/d at the station and the Cheyenne Plains West constraint point, and to 874 MMcf/d at the Cheyenne Plains East constraint point. That represented a complete restoration of its system, which had been flowing about 780 MMcf/d prior to a mid-September station fire that briefly required a total shutdown (see Daily GPI, Sept. 18).
Pacific Gas & Electric did not extend a systemwide high-inventory OFO beyond Wednesday.
El Paso said a mechanical failure Tuesday of the #2 turbine at Alamo Lake Station will require replacement of the cracked exhaust expansion bellows. Due to the uncertainty of part replacement, it estimated a time frame for the repair of about two weeks. El Paso declared a force majeure and reduced Havasu Crossover capacity Wednesday by 100 MMcf/d (from an estimated base of 620 MMcf/d).
NGPL said a gas quality problem reported last week at the Superior Taloga Dewey receipt point in Dewey County, OK (see Daily GPI, Nov. 5) has been resolved and the point is available for service again. A similar problem developed at that location in July (see Daily GPI, July 19).
Florida Gas Transmission (FGT) will begin about three days of maintenance Nov. 12 on its East White Lake Lateral upstream of Compressor Station 75 in South Louisiana. During this work FGT will schedule up to approximately 350,000 MMBtu/d on the lateral upstream of the station; normally it schedules up to 685,000 MMBtu/d there. Also, no volumes will be scheduled at the ANR/FGT St. Landry Interconnect (normally 100,000 MMBtu/d) and the Gulf South/FGT St. Landry Interconnect (normally 150,000 MMBtu/d).
To facilitate required Nov. 13-15 maintenance at Fidlar Compressor Station, Questar will reduce the capacity of its ML 80 segment to 200,000 Dth/d for those gas days. Based on current nominations, this represents a 90% reduction to flexed nominations, the pipeline said.
In response to the expressions of interest in proposed new services at the Cheyenne Hub in Weld County, CO, received during an open season that ended Aug. 21, Cheyenne Plains is holding a binding open season through Dec. 5 on such services. See the bulletin board for more details on the services.
