Oil Was Discovered in Tom Green County in 1940

Oil was discovered in Tom Green County in 1940, adding petroleum to a local economy already built on ranching and wool.

Tom Green County sits at the eastern edge of the Permian Basin, one of the most productive oil regions in the United States. Commercial oil production began here in 1940 and added a new income stream alongside cattle, sheep, and wool.

For landowners today, this history matters. Mineral rights may have been severed from surface ownership long ago. If you are buying property here, confirm whether oil and gas mineral rights are included in the sale — and if not, understand what that means for surface use.
