The Rockies region consists of properties located in Wyoming (Green River, Washakie and Powder River basins), northeast Utah (Uinta Basin) and North Dakota (Bakken and Three Forks formations in the Williston Basin).
Wells in this diverse region produce from both oil and natural gas reservoirs at depths ranging from 1,000 feet to 15,000 feet. The Company’s properties in the Jonah Field located in the Green River Basin of southwest Wyoming produce from the Lance and Mesaverde formations at depths ranging from 7,500 feet to 14,500 feet. The Company’s properties in the Washakie Basin produce at depths ranging from 7,500 feet to 11,500 feet. The Company’s properties in the Powder River Basin consist of a CO2 flood operated by Fleur de Lis Energy, LLC in the Salt Creek Field. The Company’s properties in the Uinta Basin produce at depths ranging from 5,500 feet to 15,000 feet. The Company’s nonoperated properties in the Williston Basin produce at depths ranging from 9,000 feet to 12,000 feet.
To more efficiently transport its natural gas in the Uinta Basin to market, the Company owns and operates a network of natural gas gathering systems comprised of approximately 95 miles of pipeline and associated compression and metering facilities that connect to numerous sales outlets in the area.
Rockies proved reserves represented approximately 28% of total proved reserves at December 31, 2016, of which 85% were classified as proved developed. This region produced approximately 330 MMcfe/d or 40% of the Company’s 2016 average daily production. During 2016, the Company invested approximately $41 million to develop the properties in this region.
