Marathon Oil Corporation

The company has begun damage assessments of all facilities in areas affected by hurricane Katrina, and the Company is providing assistance to employees and neighboring communities impacted by the storm.

Activities are focused on the Company's Garyville, Louisiana, refinery, which has 245,000 barrels per day of crude oil processing capacity, as well as the Marathon-operated offshore oil and gas production platforms at South Pass (located 100 miles south of New Orleans) and Ewing Bank (located 130 miles south of New Orleans).

Gross production from these facilities of approximately 18,500 barrels of oil per day (bpd) and 25 million cubic feet of natural gas per day (mmcfd), remains shut-in as a result of the storm.

Marathon's total net production from these operated facilities, as well as other non-operated properties, is approximately 43,000 bpd and 110 mmcfd and this production remains shut-in as a result of the hurricane.

Murphy Oil Corporation

The company announced today based on preliminary inspections, only minimal damage has been sustained as a result of Hurricane Katrina to the Company’s operated producing facilities at Front Runner (37.5%) and Medusa (60%) in the Gulf of Mexico.

The Front Runner field is located in 3,500 feet of water on Green Canyon Blocks 338 and 339, approximately 135 miles south-southeast of Houma, Louisiana. The Medusa facility is located in 2,200 feet of water on Mississippi Canyon Blocks 538 and 582 approximately 70 miles south of New Orleans.

No assessment has been made regarding pipelines nor can any estimated timeline be given at this time for restarting either facility or any of our other offshore Louisiana production. Some flooding occurred at the Company’s 125,000 barrel a day refinery in Meraux, Louisiana.

While repair to part of the plant’s electrical equipment and instrumentation, as well as a general cleanup of the facility, will be necessary, the refinery appears to have sustained no major damage from the storm. However, no estimate can be provided regarding timing of start-up.

The Convent Refinery is located 30 miles southeast of Baton Rouge, Louisiana near Interstate 10. The majority of the refinery’s 4000 acres are within St. James Parish on the Mississippi River. Just 750 acres have processing equipment on them and the balance of the property is maintained as a farmed greenbelt around the facility.

The Norco Refining Company is located next to the Mississippi River, about 20 miles west of New Orleans, Louisiana. The refinery has a capacity of 240,000 barrels per day. Norco is actually an acronym for New Orleans Refining Company.



ConocoPhillips

Several ConocoPhillips facilities were impacted by hurricane Katrina:
Alliance refinery remains shut down and access is limited due to flooding in the area. Most of offshore production remains shut in, however we are moving employees back to the platforms to begin assessing the situation.

In addition, many of employees have been affected by the devastation left by hurricane Katrina and the resultant flooding in Louisiana, Mississippi and Alabama.

Chevron continues to produce some oil and natural gas in the Western Gulf of Mexico region. Chevron’s New Orleans office is temporarily closed and employees and contractors who work there were advised to follow evacuation recommendations made by government agencies where they reside.
