The Company received its formation capital and subsequent equity infusions from Riverstone Holdings LLC, a private equity firm, headquartered in New York, with investments across the entire energy spectrum. Three Rivers operates assets located in the Permian Basin, one of the most prolific and largest producing oil and gas regions in the United States. Benefits of operating in the Permian Basin include numerous producing zones ranging from 1,000 to 25,000 feet, fully developed infrastructure, and a large, mature group of oilfield service providers.
