The Bureau of Land Management (BLM), within the Department of the Interior (DOI), is responsible for leasing oil and gas for development throughout the federal onshore mineral estate.  These leases may be issued on BLM lands, but also U.S. Forest Service lands, other federally owned lands, and tens of millions of acres of private lands where the federal government holds the subsurface mineral estate. At the end of fiscal year 2022, the BLM was managing around 23.8 million acres leased for oil and gas development.
