Anderson, Navasota, Iola: we buy minerals and royalties throughout Grimes County, quiet acreage on the southeastern edge of Giddings.
Grimes County is Navasota, Anderson, and the quiet southeastern edge of the Giddings field, where the chalk thins out and the Eagle Ford drilling that transformed Burleson County has not followed. There is Woodbine oil at Madisonville West on the Madison County line, a few Magnolia chalk wells on the Washington County line, and a lot of ranch land in between with a mineral deed from the 1940s and no well. Offers that show up here are usually bets on the neighbors, and we will tell you that plainly.
What produces here. Railroad Commission production for August 2026: 12,139 barrels of oil, 1,504 barrels of condensate, and about 312,000 Mcf of gas (78,000 casinghead, 234,000 gas well), from 33 fields and 35 operators. Madisonville West (Woodbine A) makes most of the oil; Giddings (Austin Chalk-3) and Giddings (Austin Chalk, Gas) make most of the gas, with Iola (Sub-Clarksville), Aguila Vado (Eagleford), and Fort Trinidad East (Buda) small. The operators you will see on checks and in the county records include CML Exploration (the largest oil producer), Magnolia Oil and Gas (the largest gas producer), WildFire Energy Operating (now part of Magnolia), Trailblazer Energy Resources, Pride Energy, Sandel Operating, Paleo Oil, Vess Oil, and Southwest Resources. The Commission approved a single new drilling permit in 2026 through November 7, CML Exploration's horizontal Nevill AC 1 at 8,950 feet, on September 15.
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.
The county's main oil, a Woodbine field shared with Madison and Brazos counties, mostly operated by CML Exploration.
The far southeastern edge of the Giddings chalk, where Magnolia's wells make most of the county's gas but little oil.
Iola (Georgetown and Sub-Clarksville) and BB (Cockfield): small conventional fields with a handful of wells each.
