The Hastings Oilfield is an approximately 20-square-mile petroleum reservoir in Brazoria and Galveston County, Texas, United States.

The Hastings Oilfield was discovered by J. W. Surface of Amoco, and was first drilled on December 23 or 29, 1934.

Within two days of the discovery, Edgar F. Bullard, also of Amoco, purchased the deed to the land, for $1 per acre.

[4][5] The Hastings Oilfield is situated in the Frio Deep-Seated Salt Dome Fields.

Its oil dates to the Oligocene, with the Marginlina, Frio and Vicksburg formations.
