Description Maybe nothing lasts forever, but Infinity Energy Resources hopes that US demand for fossil fuels won't go away for a long, long time. The company focuses its oil exploration and production operations in the Fort Worth Basin of Texas, in the Rocky Mountain region in the Greater Green River Basin in Wyoming, and the Sand Wash and Piceance Basins in Colorado. It is also pursuing an opportunity in offshore Nicaragua. The company has proved reserves of 7.8 billion cu. ft. of natural gas equivalent. Infinity Energy Resources has exited the oil services business.
