Flower Mound's Gas Wells Went Quiet. The Paperwork Didn't.

A lot of Flower Mound sellers assume that once a wellhead comes down and the pad site gets graded over, the gas well question on the contract goes away with it. It doesn't. Texas real estate contracts don't ask whether a well is currently pumping. They ask whether a lease, a reservation, or a mineral interest still exists on paper, and in a town built on top of the Barnett Shale, that paper often outlives the equipment by decades.

That gap between what's physically gone and what's still legally attached to the deed is the thing worth understanding before you list.

What Actually Closed in 2022

Flower Mound sits partly over the Barnett Shale, a natural gas formation the town's own records describe as holding an estimated 26 trillion cubic feet of gas roughly 1.5 miles below the surface. Drilling here peaked in the 2000s and early 2010s, and it didn't happen quietly. In 2011, residents of the Lakeview Estates neighborhood fought a 90-acre drilling site operated by Titan Operating after the Railroad Commission of Texas granted the company exceptions allowing hydraulic fracturing within 330 feet of homes. One resident who led the fight, Eric Jellison, told reporters at the time, "it was the last thing we could have done to stop those two wells." They lost that fight, and the wells went in.

More than a decade later, the town found a different kind of leverage. After three years of litigation over gas well inspection fees, Flower Mound settled with EagleRidge Operating in 2022. As part of that agreement, EagleRidge agreed to plug 26 of its 35 wells in town within 12 months, closing four of its seven pad sites, roughly 75 percent of that operator's wells inside town limits. Mayor Derek France called it an outcome that "led to the closure of the majority of gas wells in our community."

That's a real, verifiable retreat of drilling activity in Flower Mound. It's also not the end of the story for anyone selling a house here.

Why Closing a Well Doesn't Close the File

Texas is what's called a split estate state. The surface of a property and the minerals beneath it can be, and often are, owned by two completely different parties. When a landowner sells the surface but keeps the minerals, or sells the minerals but keeps the surface, that split gets recorded and it sticks with the property indefinitely. The Railroad Commission of Texas is direct about the practical effect: once minerals and surface are separated, the mineral estate remains dominant, meaning its owner retains the right to use the surface as reasonably necessary to reach what's underneath it, whether or not the current homeowner has any relationship with that mineral owner at all.

Many Flower Mound lots have that kind of history sitting quietly in the county deed records from the drilling boom years. A lease signed in 2007 doesn't expire just because the well tied to it was plugged in 2023. It has to be affirmatively resolved, disclosed, or reserved in writing at the time of sale, every time, regardless of whether a rig has been on the property in fifteen years.

What the Contract Actually Requires

This is where sellers get caught off guard, because the obligation isn't buried in a city ordinance somewhere. It's built into the standard Texas residential contract itself. The TREC One to Four Family Residential Contract includes a Natural Resource Lease provision, which defines a Natural Resource Lease broadly enough to cover any existing oil and gas, mineral, geothermal, water, or wind lease affecting the property. If one exists and isn't delivered to the buyer on time, the buyer gets a contractual right to terminate the deal within a set number of days after finally receiving it, with earnest money refunded.

Separately, the contract's default position on minerals is generous to buyers by design. Absent any addendum, a Texas residential sale conveys the entire fee simple estate, meaning all mineral interests the seller owns transfer automatically to the buyer. If a seller wants to keep any portion of what they own beneath the property, they can't just mention it verbally at the closing table. They need the Addendum for Reservation of Oil, Gas, and Other Minerals attached to the contract, and if they're not reserving everything, they have seven days after the contract's effective date to hand the buyer current contact information for any mineral lessee still in the picture.

Here's how that plays out depending on what a seller actually owns:

None of these paths are optional once the facts of a specific title are known. Skipping the step doesn't make the mineral history disappear. It just moves the problem to whoever finds it during the option period, which is exactly the moment a buyer has the easiest possible exit from the deal.

The Ordinance Still on the Books

Flower Mound's own gas well ordinance adds a layer specific to this town. Since 2011, any water well located within 1,500 feet of a gas well has been subject to mandatory testing, both before and after drilling, with violations carrying a fine of up to $2,000 per day. That ordinance never got repealed when EagleRidge's wells started getting plugged. It's still active town code, and it matters more now than it did a few years ago because of a change at the state level.

As of July 1, 2026, Texas sellers statewide are required to complete a new standalone Water Notice form, separate from the main Seller's Disclosure Notice, covering groundwater and surface water rights, including whether the property sits in a groundwater conservation district or has a water well on it. Combined with the updated Seller's Disclosure Notice that took effect May 28, 2026, sellers now have more paperwork touching water and mineral history than they did a year ago, not less. For a Flower Mound property with a documented well-testing history, that's not boilerplate. It's a form that can actually surface a decade-old drilling record the seller had genuinely forgotten about.

What This Actually Means If You're Listing

None of this requires panic. It requires sequencing, done early enough that it doesn't collide with a buyer's option period.

• Pull the title commitment before you list, not after you're under contract, and ask specifically whether minerals were severed from the surface at any point in the property's history.
• If a lease from the 2000s drilling era still shows up in the chain of title, get current lessee contact information lined up now so the seven day delivery window under the mineral addendum isn't a scramble.
• Decide before you write the listing whether you intend to reserve any mineral interest you hold. That decision drives which addendum, if any, gets attached to the contract.
• If your property sits near a former EagleRidge pad site or any other historical well location, expect the water well testing history to be part of the conversation under the new Water Notice form.

A buyer's agent working a competitive Flower Mound listing is going to ask these questions during the option period regardless. Having the answers ready before the sign goes in the yard is the difference between a routine step in escrow and a surprise that reopens negotiations.

A Few Common Questions

Does a plugged well mean the mineral lease is dead too? Not automatically. Plugging closes the physical well. It doesn't terminate a lease or resolve a severed mineral estate. Those are separate legal questions that require a title review to answer for a specific property.

Do I need a lawyer for this? Texas REALTORS guidance is consistent on this point: if a seller has any question about their specific mineral interests, the recommendation is to seek an attorney's advice rather than guess on the form. A straightforward case with no known severance or lease history is usually handled by title company and disclosure paperwork alone.

Does this apply to every house in Flower Mound, or just older ones near former well sites? It applies wherever a title search finds a mineral severance or an existing lease, which can be true of properties built well after drilling stopped in a given area, since the mineral history attaches to the land itself, not to when the house on it was built.
