A Houston-based company operates the oil production platform that caught on fire in the Gulf of Mexico Thursday morning.

Mariner Energy confirms the fire occurred at a platform located on Vermilion Block 380, which is about 100 miles off the coast of Louisiana. Patrick Cassidy, the company's director of investor relations, said all 13 crew members have been rescued.

Pictures from the scene indicate the workers were stranded in life jackets in the water before being brought to safety.

Coast Guard officials confirmed the fire was extinguished. Although there have been conflicting reports, officials said there are no signs of oil in the water.

This production platform is a smaller, less complex operation than the Deepwater Horizon -- the site of the BP oil spill earlier this year. Cassidy said seven wells feed into the platform, which put out about 2 percent of Mariner's overall daily oil production.

"This is a relatively small field. Production in the order of about 1,400 barrels a day. We produce in the order of 60,000 barrels a day [total]," Cassidy said.

According to Mariner's website, about 85 percent of their production came from offshore drilling as of 2009. At that time, they had nearly 350 federal offshore leases.

There was no word on the cause of the fire Thursday evening.
