BLM Rock Springs Issues Monell-Arch Oil and Gas Development Decision

The Bureau of Land Management (BLM) Rock Springs Field Office is releasing the finding of no significant impact (FONSI) and decision record (DR) for the 125 well Monell-Arch Oil and Gas Development in the Patrick Draw Field.

The 32,781 acre Patrick Draw Field has 128 producing wells and includes the 22,657 acre Monell and Arch units which have 21 producing wells. The field is located in the checkerboard of mixed federal, private and state land about 30 miles east of Rock Springs, Wyo., and is bisected by Interstate 80.

The DR approves the vertical and directional drilling of 105 oil wells, 18 carbon dioxide injector wells and two water injection wells within the Monell and Arch units over nine years with a projected well life of roughly 30 years and a maximum surface disturbance of 238 acres as analyzed in the environmental assessment (EA). The DR is subject to administrative review through the appeal process which is outlined therein.

Initial public scoping on the Monell-Arch Oil and Gas Development was conducted in fall 2012. The EA was made available for public comment in summer 2013; nine members of the public, partnerships and government entities submitted comments. All comments concerning potential impacts were addressed in the EA.

The EA, FONSI and DR are available online at
