Wild Mustang gas field

The Wild Mustang gas field in central Wyoming, operated by Lost Soldier Oil and Gas, is an emerging natural-gas development located within the Wild Mustang Federal Unit in the Bison Basin, a sub-basin of the prolific Green River Basin north of Rawlins. The project is regarded by the company as one of the largest natural gas discoveries in the western United States in several decades, with estimates suggesting resources of around 6 trillion cubic feet (Tcf) of gas. Exploration drilling-particularly the Green Mountain #4 discovery well and the Found Soldier #1 appraisal well-has confirmed approximately 3,400 ft of stacked gas-bearing pay zones across multiple reservoirs, indicating significant vertical and lateral resource potential. Development is progressing through a phased program that includes additional drilling, horizontal well planning, and the construction of midstream infrastructure to bring gas to market.

A key step is the installation of a 5.3-mile connector pipeline linking the field to existing regional pipeline networks capable of transporting roughly 400 MMcf/d, with first commercial gas sales targeted around Q4 2026 depending on regulatory approvals and infrastructure completion. In parallel, Lost Soldier has assumed full operational control of the federal unit and is advancing annual development plans, further drilling campaigns, and studies for a gas-processing facility, positioning the Wild Mustang project for gradual scale-up toward large-volume production later in the decade.
