Brookshire Dome is a shallow piercement salt dome with caprock as shallow as 3150'. It is a large dome approximately 4 miles by 3.5 miles in dimension covering approximately 5,000 acres.

Salt movement may also create reservoirs entirely extrinsic to the flanks and crests of salt domes. As the salt stocks rise and penetrate the surrounding sediments, salt is withdrawn from contiguous areas resulting in depressions termed "rim synclines." It two or more salt domes are in relative proximity to each other, counterporaneous salt withdrawal may result in an interdomal positive structure. An example of this would be the Katy Field that is near Brookshire and is created in part by salt withdrawal from that domal area.
