Who Anschutz is, and what they hold.
A privately held single-basin operator and the dominant developer of the modern Powder River Basin oil play.
Anschutz Exploration is the privately held oil and gas exploration and production arm of The Anschutz Corporation, controlled by Phil Anschutz. Headquartered in Denver, Colorado, Anschutz Exploration is among the largest privately held oil producers in the United States, with the bulk of its activity concentrated in a single basin: the Powder River Basin of Wyoming. By production volume, Anschutz is among the largest oil producers in the state.
Anschutz acquired a substantial Powder River Basin position from Occidental Petroleum in 2021, an acreage package that traced back to Anadarko Petroleum’s pre-2019 development of the basin. Since the acquisition, Anschutz has been an active developer of the position with consistent rig activity in Converse and Campbell counties, with additional acreage extending into Johnson County. Drilling primarily targets the Niobrara, Turner, Parkman, and Mowry formations through horizontal development.
