About lost soldier
Developing Domestic Energy For A Country That Needs More Power
Lost Soldier Oil and Gas is focused on a simple but important idea: America needs reliable energy, and domestic natural gas remains a critical part of that equation. The company is dedicated to responsibly developing Wyoming's Bison Basin with a practical operating plan built around field work, drilling execution, and infrastructure development.
Founder Marc Bruner has spent his career pursuing large-scale oil and natural gas opportunities in overlooked basins. Lost Soldier reflects that same mindset: find the resource, prove the geology, build the right team, and develop the asset with discipline. The company takes its name from the nearby Lost Soldier District and the historic Lost Soldier oilfield southeast of the discovery area.
Wyoming-Based Development
The company's core work is centered in central Wyoming, north of Rawlins, within the Bison Basin, a sub-basin of the Green River Basin.
Integrated Operating Model
Lost Soldier's platform includes upstream oil and gas development, midstream pipeline planning, and drilling operations designed to support the Wild Mustang project.
Domestic Energy Focus
The company's work is tied to U.S. oil and natural gas development, regional infrastructure, and local field operations.
Local Economic Impact
Lost Soldier has stated that development activity has the potential to support the local economy around Jeffrey City and the surrounding Wyoming energy region.
