Brazos County Austin Chalk Mineral Rights

Brazos County in the Giddings Trend

Brazos County (Bryan/College Station) is positioned in the northern Giddings extension of the Austin Chalk Giddings trend. The county has been part of the Austin Chalk producing region since the play's commercial development in the 1960s, and modern long-lateral horizontal redevelopment from approximately 2018 onward has revitalized many sections.

Brazos County hosts Texas A&M University and the Bryan/College Station urban area, but the bulk of Austin Chalk production sits north and east of the urban core. Surface activity is generally well-coordinated with land use; mineral owners can typically lease and sell without surface complications.

Producing Formations in Brazos County

Austin Chalk — primary producing formation; Upper Cretaceous fractured carbonate; depths typically 7,000-10,000 ft TVD across Brazos County

Eagle Ford Shale — sits stratigraphically below the Austin Chalk; many Brazos County leases cover both depths
