RICHMOND, Va. – Preliminary assessment by Dominion (NYSE: D) shows that Hurricane Katrina caused only minimal damage to its major Gulf of Mexico offshore platforms. Further examination of the platforms’ underwater pipelines and inspection of facilities is proceeding.

Dominion, one of the nation’s largest energy companies, has resumed about 75 million cubic feet equivalent (mmcfe) of its current daily offshore production of 400 mmcfe of natural gas, most of that from the West Cameron area near the Texas-Louisiana border. Dominion’s total offshore and onshore production before Hurricane Katrina was about 1.2 billion cubic feet equivalent per day.

Dominion does not have firm information on pipelines or processing facilities that transport and process its offshore output.

Preliminary examinations by Dominion and its partners showed that platforms at its major sites, including Devils Tower, Front Runner, Neptune and Main Pass 281, suffered only minimal damage. A smaller platform, Main Pass 270, incurred severe damage and will require further assessment. Main Pass 270 was producing about 11.5 mmcfe per day net to Dominion before it was shut down prior to the hurricane.

Business interruption insurance will be activated after a 30-day deductible period should production be curtailed for a longer period. Business interruption coverage includes losses from Dominion facilities as well as losses resulting from damage to pipelines and processing facilities owned by others.

Because of damage to its New Orleans offices, Dominion is temporarily moving its Gulf of Mexico offshore operations headquarters to its Houston offices.

Dominion has an energy portfolio of about 28,100 megawatts of generation, about 6 trillion cubic feet equivalent of proved natural gas reserves and 7,900 miles of natural gas transmission pipeline. Dominion also operates the nation's largest underground natural gas storage system with more than 965 billion cubic feet of storage capacity and serves retail energy customers in nine states.
