Effective Wednesday Northwest will reduce available capacity at the Boise (ID) Compressor Station from 499,000 Dth/d to 425,000 Dth/d due to damage sustained by Unit #2 this past weekend. Emergency repairs are under way and the unit is expected to be placed back in service Friday, Northwest said.

CIG reported discovering a crack Saturday in an oil cooler thermostat valve at Mocane Compressor Station in Beaver County, OK, requiring that one of the station’s compressors be taken out of service until the crack can be repaired. Because of that outage, CIG cut Mocane capacity from 43 to 23.5 MMcf/d Tuesday and declared a force majeure. Based on current estimates, CIG anticipates that repairs can be completed by the end of the week. The pipeline noted that current firm capacity commitments at Mocane are 34,560 Mcf/d.
