Eagle Ford Shale Runs Under La Salle County

The Eagle Ford is not just a map label in La Salle County. It is a shale trend about 50 miles wide and 400 miles long, running from the Mexican border toward East Texas. La Salle is one of the affected counties, so a land file here should be read with oil and gas in mind.

Texas can split the surface estate from the mineral estate. A deed may give you the pasture, fence, and gate while someone else owns the oil and gas below. If a mineral owner leases those minerals, the operator has broad rights to use the surface for drilling and production.

RRC places La Salle in Oil and Gas District 01, served by the San Antonio office. Its public GIS map and online queries let you match a tract with nearby permits, wells, and operators. The same lookup helps with a seller's old lease name, permit number, plugged well, or operator name. That record search does not answer who owns the minerals; the deed chain does.
