Denver-based Gasco Energy (NYSE Amex: GSX) is an independent exploitation and production company focused on developing tight gas sands in the United States Rocky Mountains. The Company’s primary project is in the prolific hydrocarbon-bearing Uinta Basin of Utah. SEC-defined proved reserves at December 31, 2009 were 46.9 Bcfe, 100% of which were in Utah, 94% were natural gas and 100% were proved developed.

Gasco's properties are located near major pipelines in the Rocky Mountains. Questar's 20-inch diameter system passes through Gasco's Riverbend Project.
