Surface waiver and drill-site reservation agreements for Texas solar projects
Because the mineral estate is dominant in Texas, a severed mineral owner or oil and gas lessee retains an implied right to use the surface as reasonably necessary to explore for and produce oil and gas. Solar projects address that conflict through recorded surface waivers, drill-site island reservations, and subsurface directional windows.
This is general landman reference material, not legal advice. Every tract turns on its own deed chain, active oil and gas leases, and title underwriting requirements.
In Texas, the accommodation doctrine (Getty Oil Co. v. Jones, 470 S.W.2d 618; Merriman v. XTO Energy, Inc., 407 S.W.3d 244; Lyle v. Midway Solar, LLC, 618 S.W.3d 857) protects an existing surface use only when the mineral owner has reasonable alternatives available on the leased premises. Before a solar facility is built, or where a mineral owner has no other surface access, the accommodation doctrine alone does not satisfy project lenders or title underwriters issuing a Texas T-19.4 endorsement. Instead, landmen trace every severed mineral interest and active oil and gas lease under the solar footprint and negotiate recorded Surface Waiver Agreements or Surface Use Agreements (SUAs) that waive surface entry over the tracker arrays while reserving surveyed drill-site islands, access road corridors, and directional subsurface drilling windows below a stated depth (commonly 500 feet below surface).
1Why the accommodation doctrine is not a substitute for waivers
In Lyle v. Midway Solar, LLC (El Paso Court of Appeals, 2020, pet. denied), the court held that while the accommodation doctrine can apply to a solar array once constructed, the mineral owners' trespass and breach-of-contract claims were premature until the mineral owners actually sought to develop their minerals and were impeded by the arrays. For a solar developer seeking construction financing and a T-19.4 title endorsement, waiting for a future dispute after panels are in the ground is not an underwriting option.
Title companies underwriting T-19.4 look at the county mineral chain, active Railroad Commission permits and production units, and the recorded surface waivers or drill-site reservation agreements executed by the mineral owners and lessees.
2Core provisions in a solar surface waiver or SUA
| Provision | What it does on the ground |
|---|---|
| Waiver of surface entry | The mineral owner or oil and gas lessee waives the right to enter, drill, trench, or place facilities on the surface of the solar tract (or outside designated drill-site islands). |
| Subsurface depth reservation | Expressly preserves the mineral owner's right to explore, drill horizontally or directionally, frac, and produce oil and gas below a stated vertical depth (typically 500 feet below surface grade) from surface locations off the tract or on reserved drill-site islands. |
| Designated drill-site islands (DSIs) | Metes-and-bounds or surveyed polygons set aside outside the tracker rows where the mineral estate retains full surface rights for multi-well pads, tank batteries, and separators. |
| Access and flowline corridors | Defined 30-foot to 60-foot corridors connecting each drill-site island to a public road, with crossing standards where an oilfield road or flowline crosses an underground solar collection line. |
| No pooling or royalty impairment | Clarifies that signing the surface waiver does not reduce the mineral owner's royalty decimal, alter existing oil and gas leases, or restrict pooling the tract into a horizontal unit. |
3Who has to sign: unleased minerals vs. leased working interest
A surface waiver only binds the parties who sign it and their successors in title. Our mineral ownership report separates the mineral estate into four categories so the waiver campaign targets the right signatures:
- Unleased fee mineral owners: Each undivided cotenant holds an independent right to enter the surface or lease to an operator. We track their fractional decimals and contact them directly for surface waivers.
- Leased minerals (active primary term or HBP): While an oil and gas lease is in force, the lessee (operator and working interest owners) holds the present surface-use easement, and the mineral lessor holds the reversionary interest if the lease expires. Title underwriters often ask for ratifications or surface use agreements from the operator as well as waivers from the underlying mineral owners.
- Non-participating royalty owners (NPRIs): Because an NPRI owner holds no executive right to lease or enter the surface to drill (French v. Chevron U.S.A. Inc.), an NPRI ordinarily does not hold a surface-entry right to waive, unless the creating deed reserved special surface or consent rights.
- State of Texas Relinquishment Act or GLO minerals: On state-classified mineral tracts, the General Land Office has statutory surface and leasing rules that private waivers cannot override without GLO participation.
4Sizing drill-site islands and pipeline corridors
In active basins (Permian, Eagle Ford, Haynesville, Anadarko), mineral owners and operators rarely sign a blanket zero-surface waiver on a 1,000-acre section unless they have a practical place to set a horizontal pad. Before the solar civil engineer locks the array layout, we work with the developer and the operator's land department to place 5-acre to 10-acre drill-site islands along section lines or existing ranch roads where horizontal laterals can reach the full section without shading or trenching through the solar blocks.
