An oil-well dot does not show who owns the minerals

A Wilson County deed can convey the surface, the minerals, or both. The words in the deed, earlier reservations, and mineral leases decide what moves with the sale. A well shown nearby does not answer that ownership question.

Texas generally treats the mineral estate as dominant, which gives it a limited right to use the surface for mineral work. That right is not endless. Deeds and leases can change it, and the accommodation doctrine can protect an existing surface use in some cases.

The Railroad Commission GIS viewer is useful for seeing wells and permits around a tract. It is not a mineral-title map. For a purchase, ask the title company or a qualified lawyer to trace the recorded documents rather than reading ownership from the dots.
