Mineral Rights
Oil and Gas Are a Big Deal in McMullen County
McMullen County has thousands of active oil and gas wells, so mineral rights can be a major part of any land deal here.
Oil was discovered in McMullen County in the early 1900s. Today the county has a large number of drilled wells and multiple active operators. If you buy land here, pay close attention to whether mineral rights come with the property. In Texas, mineral rights can be split from the surface. A prior owner may have kept or sold them separately.
The Railroad Commission of Texas (RRC) regulates all oil and gas activity in the state. It tracks well permits, production records, and plugging reports. You can search wells and production data by county on the RRC website. This is public information, so you can look up any tract before you buy.
