Get a Free Mineral ValuationWashington County (Brenham) is positioned in the central Giddings core 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.
Brenham (Washington County seat) is the historic center of the Texas dairy industry; the county also hosts substantial Austin Chalk production. Long-lateral redevelopment in the 2018+ era has been particularly active in the central and northern parts of the county.
Austin Chalk — primary producing formation; Upper Cretaceous fractured carbonate; depths typically 7,000-10,000 ft TVD across Washington County
Eagle Ford Shale — sits stratigraphically below the Austin Chalk; many Washington County leases cover both depths
Buda Limestone — sits above the Austin Chalk; selective production in some Washington County areas
