High demand combined with takes in excess of receipts has resulted in a loss of 140 MMcf in system linepack over the last 24 hours, El Paso said Tuesday, and its Washington Ranch storage facility was experiencing maximum withdrawals. “Scheduled pigging of the Havasu Crossover is under way, affecting access to San Juan Basin supply to the South System. The EOC [east of California] takeaway is running approximately 100 MMcf/d higher than at this time yesterday [Monday],” the pipeline said.. There is available capacity on the South System from Waha and through Guadalupe, it added. Maintenance on the San Juan Crossover and further pigging of the Havasu Crossover are scheduled for later this week, requiring that sufficient system linepack be maintained, El Paso said. A Strained Operating Condition may be declared unless the situation improves, it warned.

Based on “internal inspection data that was just received,” El Paso also said it took Line 1204 out of service upstream of Seligman Station to make repairs, reducing North Mainline capacity by 175 MMcf/d effective with Cycle 1 nominations Tuesday. The outage will continue through Wednesday. Previously scheduled maintenance on Line 1201 in the same area has been postponed until Line 1204 is back in service, El Paso said.

Westcoast, which until as recently as Aug. 4 had been encouraging packing of its system with an imbalance tolerance range of zero pack/20% draft, has transitioned all the way to the other side. For Tuesday’s gas day the range was reset to 20% pack/zero draft.

Transco reported being informed by affiliate Williams Field Services, operator of the Cameron Meadows processing facility in South Louisiana, that work being done there is behind schedule. Transco expects the outage to last through Wednesday, and said it will begin accepting nominations at six affected locations for Thursday’s gas day.

Dominion will take Pepper Station’s #2 Unit out of service on Aug. 16 for an estimated five days of maintenance. Starting at 6 a.m. EDT that day, all production in bubbles 4202 and 4203 must be shut in during the outage. Dominion will post another notice when production can be turned back on-line. Please check these notices on a regular basis as conditions are always subject to change.
