Mineral Rights in Texas Explained: What Every Central Texas Landowner Needs to Know

If you've ever read through a real estate contract for a Central Texas farm or ranch and stumbled across language about "surface rights," "mineral estates," or "executive rights," you're not alone. Mineral rights in Texas can feel like a foreign language the first time you encounter them, yet understanding how they work is one of the most important things you can do before buying or selling land in Coleman, Brown, Callahan, Concho, McCulloch, Runnels, or Taylor County. The stakes are real. In some transactions across the Big Country, the mineral estate can be worth as much as—or more than—the surface land itself.

Texas follows what's known as the "split estate" doctrine, which means the ownership of the surface of the land and the ownership of the minerals beneath it can be held by entirely different people. This is not the exception in Central Texas—it's incredibly common. When the state of Texas began issuing land grants and patents in the 1800s, minerals were often reserved or conveyed separately, and over the course of multiple generations and countless transactions, those mineral interests have been divided, inherited, sold, and leased in ways that can make tracking full mineral ownership remarkably complex. A landowner in Runnels County might hold a beautiful 500-acre ranch with a strong cow-calf operation and a productive coastal Bermuda pasture—and own absolutely none of the oil, gas, or other minerals beneath it.

Understanding the mineral estate starts with knowing what it actually includes. In Texas, the mineral estate typically covers oil, gas, coal, lignite, uranium, sulphur, and other naturally occurring substances of commercial value found beneath the surface. When you own minerals, you generally hold several "sticks" in that bundle of rights, including the right to lease those minerals to an operator, the right to receive bonus payments when a lease is executed, the right to receive royalty income from production, and something called the "executive right"—the right to make the decision to lease and to negotiate those lease terms. These rights can be held together or separated individually, which is why you'll sometimes see references to royalty interests, non-participating royalty interests (NPRIs), or overriding royalty interests in the chain of title.

One concept that surprises many first-time land buyers in the Big Country is the dominance of the mineral estate over the surface. Under Texas law, the mineral estate is considered the "dominant estate," meaning that if a mineral owner—or more commonly, an oil and gas company operating under a mineral lease—needs to use the surface to access and produce those minerals, they have a legal right to do so. They must accommodate the surface owner's existing use and can be held liable for damages, but they are not required to get surface owner permission. This is precisely why buying land with severed minerals, particularly in areas with active oil and gas exploration, deserves careful attention. In McCulloch and Concho counties, for example, the Permian Basin's eastern margins and various other plays have historically generated exploratory activity, and understanding what's been leased beneath a property—and under what terms—matters enormously for how you can use and enjoy your land.

When evaluating a property purchase anywhere in Coleman, Brown, Callahan, or surrounding counties, the first question you want answered is what percentage of the minerals are available with the surface. A property described as having "100% minerals" available is increasingly rare and genuinely valuable. More commonly, you might find a property where 50%, 25%, or even a fractional share of the minerals can be conveyed. A title company or oil and gas attorney can run a mineral title search to help establish what's actually in the ground—meaning what's actually available to convey. This search, sometimes called a "runsheet," traces the chain of title back to the original land patent and identifies every conveyance of mineral interest along the way. It's not inexpensive, but for properties where mineral activity is possible or probable, it's money well spent.

For Central Texas landowners considering selling, understanding your mineral position before going to market is just as important. If you've owned land in Brown or Taylor County for decades and inherited it from family, there's a reasonable chance that some portion of your mineral estate may have been conveyed away in a prior transaction that you're not even aware of. Reviewing your deed and getting a mineral title opinion from a qualified oil and gas attorney before listing helps you represent your property accurately and avoid complications later in the transaction process.

The lease itself—the oil and gas lease—is another area where surface owners and mineral owners alike benefit from understanding the basics. When a company wants to explore for minerals beneath your property, they will approach the mineral owner (which may or may not be the surface owner) to negotiate a lease. Key terms include the bonus, which is an upfront payment per acre for the right to explore; the royalty, which is the percentage of gross production revenue the mineral owner receives if production occurs; and the primary term, which is the initial period during which the company must begin drilling or lose the lease. In the Big Country, royalty rates have historically ranged from 1/8 (12.5%) on older leases to 1/4 (25%) or higher on more recent negotiations, depending on how active the play is and how much leverage the mineral owner has. If you're approached about leasing your minerals, consulting with an oil and gas attorney before signing anything is strongly advisable.

For surface owners in Central Texas who don't own their minerals, the Surface Damage Act provides some protection. Any operator who enters your property to conduct oil and gas operations is required to negotiate a surface use agreement with you, which can address the placement of roads, pipelines, tank batteries, and equipment, as well as compensation for crop damage, lost agricultural productivity, and restoration of the land after operations conclude. This is a negotiation, and surface owners are not without leverage. A well-drafted surface use agreement can protect your operation—whether you're running stocker cattle on native grasses and brush, maintaining a wildlife management program for whitetail deer and wild turkey, or farming dryland crops in the more level terrain of Runnels County.

It's also worth understanding how mineral ownership—or the lack of it—can affect property taxes and agricultural exemptions. In Texas, mineral interests are assessed and taxed separately from surface property. If you own minerals that are under a producing lease, those interests will carry their own appraised value and generate a separate tax bill through the county appraisal district. Meanwhile, your surface agricultural exemption—which is one of the most valuable tools available to Central Texas landowners running cattle, raising crops, or managing wildlife under a 1-d-1 ag use valuation—is based entirely on the surface's productive use and is unaffected by mineral ownership. A consultation with your county appraisal district and a tax professional can help you understand how your specific situation is classified and taxed.

One area of growing interest in the Big Country is the distinction between oil and gas minerals and other subsurface resources—particularly water. In Texas, groundwater is treated entirely differently from oil and gas. Groundwater is generally owned by the surface owner under the "rule of capture," and it is managed by groundwater conservation districts rather than the Railroad Commission, which oversees oil and gas. In Taylor, Callahan, and Coleman counties, where average annual rainfall runs roughly 22 to 26 inches and water availability is a significant factor in land value and agricultural productivity, understanding your water rights and your groundwater district's rules is a separate but equally important conversation. Don't assume that having strong mineral rights means you have strong water rights—or vice versa.

The bottom line for anyone buying or selling land in Central Texas is this: minerals matter, and the details matter. Whether you're evaluating a 200-acre hunting property in McCulloch County, acquiring a working ranch in Coleman County with established coastal pastures and a solid cow-calf history, or putting family land in Brown County on the market for the first time, understanding the mineral estate—what you own, what you can convey, and what obligations run with the land—is fundamental to making informed decisions. Texas mineral law is nuanced enough that no blog post is a substitute for qualified legal counsel, and I always encourage buyers and sellers to work with a licensed oil and gas attorney when mineral interests are part of the transaction.

What I can do is help you look at a property through the lens of someone who works this land every day—someone who understands how the mineral picture, the surface conditions, the water availability, and the agricultural or wildlife potential all fit together into the full value of a Central Texas farm or ranch.
