BLM Rock Springs Issues Decision
on Table Rock Oil and Gas Development

The Bureau of Land Management (BLM) Rock Springs Field Office (RSFO) is releasing the environmental assessment (EA), finding of no significant impact (FONSI), and decision record (DR) authorizing Chevron U.S.A., Inc. to expand the Table Rock Field with development of up to 88 new wells.  

The Table Rock Field encompasses 13,644 acres of primarily federal and private land, with a small amount of state-owned land, approximately 40 miles east of Rock Springs, Wyo. in Sweetwater County. The project straddles the boundaries of the Rock Springs and Rawlins field offices, with the RSFO acting as project lead. The Table Rock Field was developed in 1945, and presently has 100 producing wells, along with a gas processing plant operated by Chevron. The new development includes a combination of vertical and directional drilling of 33 shallow oil wells, 20 deep gas wells, and up to 35 water injection wells at depths ranging from 7,000 to 15,000 feet depending on geologic formation. Eighteen existing wells will also be converted to water injection wells. Chevron plans to develop the wells during the next 14 years. The maximum surface disturbance is anticipated to be slightly more than 300 acres, with the life of the wells projected to be between 40 and 55 years.  

Initial public scoping on the oil and gas development was conducted in May-June 2011. The EA was made available for public comment in November-December 2011, and all comments concerning potential impacts were addressed in the EA. The DR is subject to administrative review through the appeal process, which is outlined in the Decision Record. A copy of the EA, FONSI, and DR are available at:

The BLM manages more than 245 million acres of public land, the most of any Federal agency. This land, known as the National System of Public Lands, is primarily located in 12 Western states, including Alaska. The BLM also administers 700 million acres of sub-surface mineral estate throughout the nation. The BLM's mission is to sustain the health, diversity, and productivity of America’s public lands for the use and enjoyment of present and future generations. In Fiscal Year 2015, the BLM generated $4.1 billion in receipts from activities occurring on public lands.
