Geothermal rights and leasing for landowners.

If an energy developer has approached you regarding a geothermal lease, option, or surface access agreement, here is how subsurface rights are defined under state law.

Who owns the heat under your land?

For decades, Texas law had ambiguity regarding whether geothermal heat belonged to the surface owner or the mineral owner when estates were severed. In 2023, the Texas Legislature enacted Senate Bill 785, codified in Texas Natural Resources Code Section 141.004(a):

"Except as otherwise expressly provided by a conveyance, contract, deed, reservation, exception, limitation, lease, or other binding obligation, the geothermal energy and associated resources below the surface of land are owned as real property by: (1) the landowner; or (2) if the surface estate and the mineral estate of the land have been severed, the owner of the surface estate of the land."

This means that under Texas law, if you own the surface of the land, you own the geothermal heat beneath it by default, even if an oil and gas company or former owner holds the oil, gas, and mineral rights. However, any specific reservation in your chain of deed records can alter this default, which is why a thorough courthouse title search is essential.

Surface Use Agreements (SUA): Protecting your property

A geothermal operation involves large drilling equipment, circulation pumps, piping networks, and electrical interconnect lines. Never sign a bare lease without an enforceable Surface Use Agreement that defines:

Key lease clauses to scrutinize

Before executing any contract, review these critical terms with your qualified oil and gas attorney:

Existing wellbores on your property

Developers frequently look to repurpose idle, shut-in, or unplugged oil and gas wells for geothermal heat extraction. If a company approaches you to evaluate a wellbore on your land, ask:

  1. Who is the current operator of record? Check Texas Railroad Commission records to confirm whether the well has an active Form P-5 operator or is currently an orphan well.
  2. Will the developer assume all regulatory liability? A transfer of operator status requires Railroad Commission approval (Form P-4) and financial security under 16 TAC Section 3.14. Never permit operations without documented liability transfer.
  3. What mechanical integrity testing will occur? Old oilfield casings may have corrosion or pressure limitations that make them unsuitable for high-temperature fluid circulation without major recompletion.
