About 61.6% of the usual 7.4 Bcf/d of Gulf of Mexico (GOM) natural gas production remained shut in Tuesday, the Minerals Management Service (MMS) reported. Eleven of the 26 major gas pipelines and seven gas processors in the Gulf Coast area also remained shuttered, but offshore operators were reporting some success in restoring production to pre-hurricane levels.

The MMS, which based its latest gas and oil shut-in estimates on 63 operators’ reports, said 66.8% of the GOM’s 1.3 million b/d of oil also remained shut in. With 23 manned platforms confirmed destroyed by Hurricane Ike, 203 production platforms, or 29.3% of the remaining 694 manned platforms in the GOM, remained evacuated. There also are five confirmed rigs destroyed, and based on the revised total of 116 GOM rigs operating, MMS estimated that four rigs, or 3.5%, remained evacuated.

In Louisiana the Department of Natural Resources (DNR) reported that 21%, or 32,477 b/d, of the state’s usual oil production of 144,767 b/d has been restored. The estimated amount of restored gas production is 504 MMcf/d, or 31%, of the daily production capacity of 1,642 MMcf/d. The estimated amount of shut-in gas production is 825 MMcf/d; the status of the remaining 312 MMcf/d has not been confirmed, DNR stated.

Damage assessments continue to be performed both onshore and offshore, said the Department of Energy’s (DOE) Office of Electricity Delivery and Energy Reliability. In its Tuesday update, the DOE reported that 11 gas pipelines remained shut in.

Among the damages is a report by Discovery Gas Transmission (DGT), which notified its customers that an 18-inch diameter gathering line lateral was torn from its interconnection with the 30-inch mainline of DGT’s offshore system. The damage to the offshore facilities will prevent DGT from receiving gas flow along its entire mainline for a minimum of one month. DGT also notified customers that all receipt points and some delivery points onshore are accepting gas flow at this time.

Enbridge Inc. is reporting progress on its offshore repairs. The company’s U.S. unit said repairs on its 16-inch Manta Ray offshore gas gathering system were nearly completed, and the line is expected to return to partial service by Thursday. Enbridge’s Mississippi Canyon gas pipe began accepting nominations on Sunday, but interconnections with Tennessee Gas Pipeline and the Venice, LA, natural gas processing plant remained unavailable.

Enbridge’s Garden Banks Gas Pipeline has completed its repairs and is ready to return to service. However, the pipe is expected to remain shut in because of the unavailability of interconnections along its systems. Garden Banks had no time frame for when service would begin. The Enbridge Offshore Pipeline System, Stingray pipeline and Nautilus pipeline remained under force majeure; the Nautilus system may be restored by Thursday, but there was no estimate given for the other pipes.

Of the 39 major gas processors that were affected by Hurricane Ike and earlier this month by Hurricane Gustav, seven plants remained shuttered, the Energy Information Administration (EIA) stated. The seven plants have a total operating capacity of 4.68 Bcf/d. In addition, EIA reported that 24 plants have resumed operations at reduced or normal levels with a total operating capacity of 9.2 Bcf/d. Seven more plants, with operating capacity of 3.59 Bcf/d, are capable of restarting once power is restored and/or upstream gas flow is sufficient.
