Katrina -- Oil Production, Refining

37 production platforms were destroyed in the Gulf's shallow waters and 15 were seriously damaged.

One of the largest of those damaged is Royal Dutch Shell's Mars platform (pictured), which received significant damage to its topside superstructure.



Companies continued to restart platforms:
Andarko Petroleum's Marco Polo back up to full output.
BP's Holstein facility producing 70,000 barrels a day.
Louisiana Offshore Oil Port 75% capacity on Tuesday.

Pipelines:
Enbridge Energy said its 30-inch pipeline in the Mississippi Canyon may take weeks to reopen.
Pipeline operators like El Paso, Enterprise Products Partners and Williams Partners have not been able to inspect all of their facilities.

Major damage at Chevron Corp.'s 325,000-barrel-a-day refinery at Pascagoula, Miss., and ConocoPhillips' 247,000-barrel-a-day plant at Belle Chasse, La. may keep as much as 5 percent of the country's refining capacity offline for weeks.

20 new shipments of gasoline are en route to U.S. ports in the next week representing barely half of U.S. gasoline daily consumption.

Oil Production, Refining Capacity Expected to Return to Normal by November

Four of the 10 refineries that were shut down are expected to be back at full capacity within the next week and six refineries that had to scale back production were expected to be back at full capacity by Thursday.

Domestic oil production should return to just under 5.4 million barrels a day in November, the level it was in August before Hurricane Katrina disrupted most of the Gulf production and knocked out ten Gulf coast refineries.
