Galveston, UNITED STATES: An oil refinery is pictured 22 September 2005 on Galveston Bay in Texas City, TX. Hurricane Rita threatens a large portion of the US oil and gas operations industry in the Gulf of Mexico and along the Texas coast just weeks after a devastating blow to the sector from Katrina. Oil producers and refiners were attempting to secure their facilities in the face of a storm that threatens about 27.5 percent of the industry, said Red Cavaney, president of the American Petroleum Institute.
