US-STORM-ISAAC-ENERGY:Factbox: Gulf of Mexico oil, gas operations affected by Isaac
(Reuters) - Isaac, now a tropical depression, continued to threaten the lower Mississippi valley with heavy rain and flash floods as it moved north after forcing offshore energy producers and coastal refiners to shut operations.
Energy companies have begun assessing the damage caused by the storm, which made landfall as a Category 1 hurricane on Tuesday. Some will be resuming operations on Friday.
Phillips 66 said floodwater at the Alliance refinery in Belle Chasse, Louisiana did not reach more than 2 feet in depth, although it did not say which parts of the refinery were flooded. The refinery remains shut with no timeline given for a restart.
Valero Energy Corp is ramping up rates at its 180,000 barrels-per-day refinery in Memphis, Tennessee after Royal Dutch Shell started its Capline pipeline system.
Shell said Friday that Motiva Enterprises' 233,500 bpd refinery in Norco, Louisiana will restart some units after it was shut during the storm because of power loss and wind damage.
Exxon Mobil Corp was conducting checks at its 192,500 bpd Chalmettte, Louisiana joint-venture refinery, it said Friday.
The U.S. Department of Energy will loan 1 million barrels of sweet crude to Marathon Petroleum Corp, which was operating its 490,000 bpd Garyville, Louisiana refinery at reduced rates after Isaac hit the Gulf Coast. Sources said the department received only one request for crude oil loans from the reserves.
The department estimated some 878,000 barrels per day of oil refining capacity remains offline on the Gulf Coast.
Anadarko Petroleum Corp will restaff five Gulf of Mexico platforms Friday and production will start once inspections are done and third-party pipelines ramp back up.
BP Plc, the largest oil producer in the Gulf of Mexico, said the company was restaffing its shut oil and gas platforms and would restart production "in coming days" once it was deemed safe.
ATP Oil and Gas said it is restaffing and restarting its Titan and Innovator platforms in the Gulf of Mexico on Friday.
Murphy Oil said it will begin restaffing Gulf of Mexico operations on Friday.
Oil firm Anadarko Petroleum Corp said it would start restaffing its shut Gulf of Mexico platforms on Friday.
Chevron started deploying personnel to its offshore facilities on Thursday but said its 330,000 barrel-per-day (bpd) Pascagoula, Mississippi refinery and is still operating at reduced rates.
The U.S. Bureau of Safety and Environmental Enforcement said 94.81 percent of oil and 68.34 percent of natural gas production was disrupted by the storm in the Gulf.
The Gulf of Mexico accounts for about 23 percent of U.S. oil production and 7 percent of natural gas output, according to the U.S. Energy Information Administration. About 30 percent of U.S. natural gas processing plant capacity and 44 percent of the country's oil refining capacity lies along the Gulf Coast, the EIA said.
The Port of New Orleans and a stretch of the Lower Mississippi River were opened with restrictions on Thursday night, the U.S. Coast Guard said. The port of Morgan City in Louisiana was opened at 7 p.m. CDT.
The Louisiana Offshore Oil Port (LOOP), which handles about 13 percent of foreign crude shipped to the United States, deliveries from its onshore storage facilities at Clovelly, Louisiana, and expects to restart offshore crude tanker offloadings as soon as possible.
Chevron Corp Subsidiary Sabine Pipeline LLC said its natural gas pipeline and interconnections to the Henry distribution hub in Louisiana were not affected by Isaac. The Henry Hub natural gas delivery point was operating normally Thursday.
Oil output shut: 1.31 million bpd nearly unchanged from Thursday.
Natural gas output shut: 3.07 bcf/d, down from 3.263 bcf/d Thursday.
