Property rights collide in South Texas when an inactive oil well sits just yards from a major river. You own the land, but an energy company demands the legal right to cross your gates. Who wins?
A Texas appeals court recently answered that question, ruling that an oil operator can legally cross private ranchland to plug a long-dormant well. It is a decision that exposes the raw tension between private property ownership and the rigid environmental liabilities tied to old energy infrastructure.
The Battle Over South Texas Access
The legal fight centers on the Remora Oil Unit, a drilling site located on the Wright Land property. For years, accessing this remote infrastructure followed a predictable pattern. Operators used a private road cutting across the Dierlam Ranch, part of the historic McFaddin family property network that dates back to the nineteenth century. Between 1996 and June 2015, previous operators paid more than $120,000 for that road usage.
Money talks, until the wells go dry.
When the well was shut in, the payments stopped. Negotiations between landowners and successive operators broke down completely. By 2021, Allegiant Resources LLC took over operations of the Remora Oil Unit and faced a brick wall. Mark Clayton Dierlam, who manages the ranch, slammed the door on access after initial exploratory visits in 2022. Financial terms could not be reached, and private property lines suddenly became fortifications.
Why the Oil Company Needed Through
Allegiant wasn't trying to squeeze fresh crude out of a dying field. They wanted in for one reason: plugging an abandoned well.
According to testimony from Lee Lawrence Lawson, Allegiant's HSE director, the physical location of the well made it an acute liability. It sits roughly fifteen to twenty yards from the San Antonio River. Leaving a decaying, shut-in well that close to a major waterway invites disaster. State regulators do not look kindly on neglected infrastructure sitting in floodplains.
Lawson pointed to staggering stakes. If Allegiant failed to complete the required plugging and surface equipment removal mandated by the Texas Railroad Commission, the financial blow could hit $50 million in potential losses and severe regulatory penalties. They weren't fighting for profit; they were fighting to escape a massive compliance nightmare.
The Legal Reality of Accommodation
Texas property law walks a tightrope between surface owners and mineral estate holders. Minerals are traditionally dominant, meaning the oil and gas operator usually possesses an implied easement to use the surface to extract resources. But what happens when extraction stops, and the mission shifts entirely to environmental remediation?
The Texas Thirteenth Court of Appeals sided with Allegiant on October 1st, affirming a lower court ruling. The message is clear: operators retain a limited right to cross neighboring private land if that entry is strictly necessary to fulfill state-mandated plugging obligations.
You cannot block an operator from cleaning up a toxic or regulatory hazard just because you are tired of them driving across your pasture. At the same time, the ruling does not grant open-ended access. It is surgically targeted at getting the plugging job done, removing the old equipment, and mitigating ecological risks near the riverbank.
What This Means for Landowners and Operators
This case offers a blunt lesson for anyone managing rural property near legacy energy assets.
If you own land crossed by old oil and gas paths, cutting off access out of frustration rarely works long-term. State regulators hold immense power over orphaned or abandoned wells, and courts will generally side with operators who are trying to satisfy those regulatory demands. Refusing to negotiate often leads to protracted litigation that costs both sides dearly in legal fees.
For operators, ignoring surface owners is a recipe for expensive court battles. Building collaborative relationships with ranch managers prevents years of delays. When an inactive well sits yards from a vital waterway like the San Antonio River, cooperation beats courtroom combat every single time.
Keep your legal agreements clear, understand your state's accommodation doctrines, and remember that old wells never truly die until they are properly plugged.
