Buttes

Anadarko Petroleum Corp. has reduced its natural gas-operated rig count in the Marcellus Shale and in the Greater Natural Buttes of Utah to put more mechanical muscle into the oily Wattenberg field of Colorado, which is delivering the highest rates of return (ROR) in the U.S. onshore portfolio, said CEO Al Walker.

CIG said work on a force majeure outage of Natural Buttes Station that began in late January (see Daily GPI, Jan. 28) is now expected to continue through March. The pipeline was able to raise operationally available capacity through the station from 80 MMcf/d to 120 MMcf/d shortly after the outage commenced. It set the total capacity for receipts at Uintah Station and Meter Station 101 at 135 MMcf/d Thursday until further notice.

CIG plans smart pigging of the Uinta Basin Lateral in late May. On May 23 and again on May 27, flow from Natural Buttes Compressor Station must be cut to about 100 MMcf/d for about 10 hours each day. For 27 hours beginning on May 25 and again on May 29 for about 27 hours, flow from Greasewood Station to Wamsutter Station must be reduced to about 100 MMcf/d. Construction work related to the Pipeline Integrity Program (PIP) will require the shut-in of Table Rock Residue volumes for 16 hours on May 17. PIP construction will require sections of the Wyoming mainline between the Laramie and Cheyenne Compressor Stations to be removed from service for short periods (less than 24 hours) May 1 and 2 and again May 10-12. Impact to service is expected to be minimal. No service intereruption is anticipated during May 7-8 PIP construction between Cheyenne Compressor Station and the Cheyenne meter station.
