Crystal City, La Pryor, Batesville: we buy minerals and royalties throughout Zavala County, on the Eagle Ford's western edge in the Winter Garden.
Zavala County is the spinach capital and the shallow western edge of the Eagle Ford, which is a less glamorous address than La Salle but a real one. The wells are shallow, the laterals are short, and the operators are smaller, which keeps offers for Zavala minerals low and sometimes lazy. The spinach is still in Crystal City; the royalty owners mostly are not.
What produces here. Railroad Commission production for August 2026: 462,294 barrels of oil, 33,621 barrels of condensate, and about 806,000 Mcf of gas (515,000 casinghead, 291,000 gas well), most of it from Briscoe Ranch (Eagleford), with Pearsall (Austin Chalk), Pearsall (Buda) and Pena Creek (Georgetown) behind it. The operators you will see on checks and in the county records include EXCO Operating, Buffco Production, Trinity Operating (USG), CML Exploration, Magnolia Oil and Gas (which sold its non-core Zavala and Dimmit wells in the third quarter of 2026), U.S. Energy Development, Formentera Operations, and Etoco. The Commission approved 18 new horizontal drilling permits in 2026 through November 7: Rosewood Resources 9, BlackBrush Oil and Gas 5, GulfTex 2, and one each for Buffco and Formentera, with Rosewood's three Holdsworth C wells approved September 28.
Whatever you own here, producing royalties, non-producing acreage, or an inherited fraction split among family, we will identify it from whatever paperwork you have, value it off the actual wells and activity, and show you the reasoning with the offer. Free, no obligation, and no pressure: if keeping it is the right answer, we will say so. Inherited it? Start with inherited mineral rights in Texas.
