Sell Mineral Rights
in La Salle County,
Texas.
La Salle County sits in the heart of the western Eagle Ford in South Texas, across the volatile oil and condensate windows. Wells here produce a mix of oil, condensate, and natural gas. If you own minerals here, you are in one of the longest-developed unconventional plays in the country. We are happy to help you understand what you have.
The western Eagle Ford,
where oil meets condensate.
La Salle County sits in South Texas, roughly between San Antonio and Laredo, with the county seat at Cotulla. The Eagle Ford shale runs in a broad arc across South Texas, and La Salle sits across the volatile oil and condensate fluid windows of the broader Eagle Ford play. That position shapes everything about how wells produce here.
The Eagle Ford was one of the first major US unconventional plays to be developed at scale, with significant horizontal drilling beginning in the late 2000s and continuing through today. La Salle County was an early focus, and many of the older wells in the county date to that initial wave. Modern activity is more selective than the boom years, but operators including EOG Resources and ConocoPhillips (through the 2024 Marathon Oil acquisition) continue to drill, refrac older wells, and develop the Austin Chalk above the Eagle Ford in places. Mineral owners across the play often hold positions that span La Salle and neighboring Karnes and DeWitt counties.
If you are reading this, you may own a piece of that. Maybe your family has held minerals here since the original ranching days. Maybe you inherited a small fractional interest and have been getting royalty checks in the mail for years. Maybe an operator just sent you an offer and you are not sure what to make of it. This page walks through the rock, the operators, the geography, valuation, and the regulatory landscape.

Two productive horizons
in the South Texas column.
La Salle County's productive geology is anchored by the Eagle Ford shale, with the Austin Chalk sitting directly above as a secondary horizontal target in many areas. Older vertical production from various intervals also exists across the county.
The Eagle Ford is an organic-rich, calcareous shale deposited during the Late Cretaceous. Across La Salle County it generally runs around nine to eleven thousand feet deep, varying with location. The formation is divided into a Lower Eagle Ford (the primary target across most of the play) and an Upper Eagle Ford that has seen selective horizontal development.
Because La Salle sits across the volatile oil and condensate windows, Eagle Ford wells here produce a mix of oil, condensate, and natural gas, with the ratio shifting as you move across the county. For mineral owners, this means royalty income comes from multiple revenue streams rather than just oil, and post-production cost deductions for gas processing and gathering are typical.
The Austin Chalk sits directly above the Eagle Ford and has produced in South Texas for decades, going back to early vertical fracture-fairway development in the 1970s and through several modern horizontal cycles. The Chalk is a fractured carbonate, and producibility depends heavily on natural fracture density and rock quality, which varies across La Salle.
For mineral owners, an Austin Chalk well on your section can be a meaningful additional revenue stream on top of Eagle Ford production. Some operators have developed both horizons on the same units. Where Austin Chalk inventory remains, it adds optionality to mineral valuations.
Before the Eagle Ford and Austin Chalk became horizontal targets, La Salle County had decades of vertical production from various Cretaceous intervals. Some of that legacy production continues at low rates and still generates royalty income for owners.
The practical implication is that some mineral interests in La Salle have layered production: legacy vertical wells, modern Eagle Ford horizontals, and in some cases Austin Chalk horizontals, all on the same minerals. Each carries its own decline curve and revenue stream.
Who is drilling on your
La Salle County minerals.
The Eagle Ford operator landscape has consolidated meaningfully over the last decade, with several large public and private operators holding the bulk of the active drilling positions. The operators below are leaders in current La Salle County activity, but the county has many more meaningful operators than this list captures.
We know how these operators develop in La Salle County. Happy to give you context on yours.
Not all La Salle County
minerals are built the same.
La Salle County covers about 1,500 square miles in South Texas, with Cotulla as the county seat and largest town. The Eagle Ford fluid window shifts as you cross the county, with northern and central areas typically in the volatile oil window and southern areas pushing into condensate. Where in the county your minerals sit shapes activity, fluid stream, and economics.
What your La Salle County
mineral rights are worth.
Valuation in La Salle County reflects the maturity of the Eagle Ford as a play. The county has been drilled actively for over a decade, so remaining inventory varies meaningfully section by section. Producing wells, refrac potential, Austin Chalk overlay, and lease terms all factor in. The four scenarios below cover what we see most often.
We would rather look at real facts than speak in generalities. Send us what you have.
Texas rules,
South Texas realities.
La Salle County operates under the Texas oil and gas regime, administered primarily by the Texas Railroad Commission. The on-the-ground realities of operating in South Texas reflect a long-developed play with mature unit structures, established midstream infrastructure for processing condensate and gas, and county-level practices that have been refined over more than a decade of horizontal drilling.
The Railroad Commission and how Texas regulates
The Texas Railroad Commission (RRC) regulates oil and gas operations across the state. La Salle County falls within RRC District 1, which covers a large portion of South Texas. The RRC permits wells, oversees spacing and pooling, maintains the public well database, and handles complaints about production accounting and royalty payment. Texas is a private-mineral state with comparatively limited state mineral ownership, which means most leasing in La Salle is between private mineral owners and operators.
Pooling, units, and production sharing
Texas does not have compulsory pooling in the same way some other states do. Operators in the Eagle Ford typically form pooled units by including pooling clauses in leases or by negotiating separate pooling agreements. Production sharing agreements and allocation wells are also used to allow long laterals to cross multiple lease boundaries. Mineral owners receive royalties based on their proportionate share of production allocated to the unit or tract.
Post-production costs and condensate streams
Eagle Ford wells in La Salle produce a mix of oil, condensate, and natural gas. Gathering, processing, and transportation all carry costs that may be deducted from royalty payments depending on the lease language. Texas case law on post-production cost deductions is meaningful and lease language matters. Reading your specific lease's royalty clause carefully is worth doing.
Surface use and South Texas ranching
La Salle County has a deep ranching tradition, and many mineral and surface estates have been split over the years. Surface use agreements between operators and surface owners are common, and the legal framework distinguishes between mineral and surface rights. If you own minerals but not the surface (or vice versa), that distinction shapes what you do and do not control.
