<p><br /> A fire caused by an explosion on an oil platform off the Louisiana coast has been extinguished, the Coast Guard has confirmed.<br /> </p><p><br /> Initial reports suggested that an oil sheen a mile long and 100 feet wide had begun to spread from the site of the blast, about 200 miles west of the site of BP's massive Deep Horizon oil spill.<br /> </p><p><br /> But hours later, Coast Guard officials said crews were unable to find any spill.<br /> </p><p><br /> "The fire is out, and Coast Guard helicopters on scene, and vessels on scene, have no reports of a visible sheen in the water. There is no report of an evidence of leaks," Coast Guard official Peter Troedsson said at a news conference in New Orleans.<br /> </p><p><br /> The company that owns the platform, Houston-based Mariner Energy, did not know what caused the explosion.<br /> </p><p><br /> Mariner officials said there were seven active production wells on the platform, and they were shut down shortly before the fire broke out.<br /> </p><p><br /> Louisiana Governor Bobby Jindal said the company told him the fire began in 100 barrels of light oil condensate, but officials did not know yet what sparked the flames.<br /> </p><p><br /> The platform is in about 340 feet of water and about 100 miles south of Vermilion Bay on the central Louisiana coast.<br /> </p><p><br /> Its location is considered shallow water, much less than the approximately 5,000 feet where BP's well spewed oil and gas for three months after an April rig explosion.<br /> </p>
