We get calls at our office fairly regularly from mineral owners who have just stumbled across a frustrating piece of math. They look at the activity on their family land in New Mexico, do some back-of-the-napkin calculations, and realize their operator is quietly selling something besides oil and gas.

They are selling water. Millions of barrels of it.

For decades, the briny, chemical-laden fluid that comes up alongside oil—known in the industry as :produced water—was considered toxic garbage. It was a massive liability. Oil companies spent a fortune trucking it away and shoving it deep underground into disposal wells.

Then the technology changed. Operators figured out how to recycle this fluid and use it for new hydraulic fracturing jobs. Suddenly, in the bone-dry Delaware Basin of New Mexico, this “waste” became incredibly valuable. Oil companies started treating it and selling it to the operator next door.

Naturally, the families who own the land started asking a very reasonable question: If this fluid is coming out of my dirt and being sold for a profit, where is my royalty check?

The answer is simple, legal, and tough to swallow. You do not get one.

The state of New Mexico legally shifted control of that water away from landowners and handed it directly to the oil companies. Let’s look at exactly how that happened, why the state allowed it, and what it means for your family’s assets.

The Problem With Fresh Water in the Desert

To understand how we got here, you have to understand the sheer volume of water required to operate in the Permian Basin.

A single modern frack job can easily consume 15 to 20 million gallons of water. In the past, operators pumped that fresh water out of local aquifers. But New Mexico is a desert. There simply is not enough fresh groundwater to sustain the massive scale of modern drilling without eventually draining the local towns and agricultural communities dry.

At the same time, the wells themselves were generating an ocean of wastewater. Depending on the specific rock formation, a well might bring up four to ten barrels of produced water for every single barrel of crude oil.

This created a dual crisis. Operators were draining fresh aquifers on the front end, and desperately looking for places to dump toxic wastewater on the back end.

The solution was recycling. If an operator could treat the produced water to remove the heavy metals, salts, and solids, they could turn around and pump it back down a new well. It solved the disposal problem and the fresh water problem in one move.

But recycling facilities cost millions of dollars to build. To make the economics work, operators needed a way to monetize the treated water. They needed to be able to sell it to midstream companies or neighboring operators.

There was just one legal roadblock. Who actually owned the water?

Historically, property law in the United States generally assumes that if something comes out of your land, you have a right to it. If someone takes a resource from your property and sells it to a third party, you expect a cut.

This assumption created a massive gray area for recycled frack water. Operators were hesitant to invest millions in recycling infrastructure if surface owners or mineral owners were going to show up demanding a 20% royalty on every barrel of water sold.

So, the oil and gas lobby went to the New Mexico legislature to get clarity. They got exactly what they wanted.

In 2019, the state passed the Produced Water Act. The most critical part of this legislation is found in New Mexico Statutes Section 70-13-4. The language is completely unambiguous. It states that all produced water from an oil or gas well is the responsibility of, and under the control of, the operator and :working interest owners.

But the legislature did not stop at assigning responsibility. They explicitly assigned the money.

The law states that the operator shall have a :possessory interest in the produced water, including the right to take possession of it and to “use, handle, dispose of, transfer, sell, convey, transport, recycle, reuse or treat the produced water and to obtain proceeds for any such uses.”

Read that last part again. And to obtain proceeds for any such uses.

With a single sentence, the state of New Mexico decreed that the oil company—not the family who owns the surface, and not the family who owns the minerals—has the legal right to sell the recycled water and keep 100% of the profits.

Why the Surface Owner Also Loses Out

When mineral owners realize they aren’t getting a cut of the water, they often assume the surface owner must be getting paid instead. After all, groundwater is traditionally considered part of the surface estate.

But the surface owner does not get the money either.

New Mexico property law operates under the concept of a dominant mineral estate. As detailed in a legal breakdown by The Energy Law Group, the mineral estate holds dominance over the surface estate. This means the mineral owner (and their lessee, the operator) has the implied right to use as much of the surface as is reasonably necessary to extract the oil and gas.

Now, the operator cannot just destroy the surface without consequence. They are bound by the :accommodation doctrine and the New Mexico Surface Owners Protection Act (SOPA). SOPA requires operators to give notice before disturbing the land and mandates that they compensate the surface owner for damages. They even have to post a bond with a New Mexico financial institution to guarantee they will return the land to its original condition.

But surface damages are a one-time payment for dirt and disruption. It is not a royalty. The surface owner gets compensated for the tractor ruts and the footprint of the well pad, but they do not get a cut of the recycled water being piped off their land and sold down the road.

If you own minerals under a road or a neighbor’s farm, you already know how complicated severed estates can be. We explored this dynamic previously in The Invisible Estate: Who Owns the Minerals Under Your Road?. But in the case of produced water, the split estate does not matter. The law simply handed the resource to the operator.

The Environmental Fence: Why It Stays in the Oilfield

You might wonder why operators don’t sell this treated water to local farmers or municipalities. If it is cleaned up, couldn’t it help solve New Mexico’s broader drought issues?

The short answer is no. The state strictly regulates where this water can go.

According to an analysis by Holland & Hart, the New Mexico Environment Department’s Ground Water Quality Bureau explicitly limits the reuse of produced water outside of the oil and gas sector. The state categorizes produced water as both a “water contaminant” and a “water toxic” under New Mexico water quality statutes.

Even if an operator treats the water to near-drinking quality, they are outright prohibited from discharging it into any surface water. They cannot put it in rivers, and they practically cannot discharge it into groundwater aquifers. The state will only allow highly regulated “demonstration projects” for outside use, and even those cannot involve discharging the water into the natural environment.

Because of these environmental guardrails, the recycled water is legally trapped inside the oil and gas ecosystem. Its only real market is other oil and gas operators. This closed-loop system perfectly isolates the revenue stream, ensuring the money just trades hands between drilling companies while the original landowners watch from the sidelines.

The Bigger Picture: The Changing Value of Your Land

I completely understand why families feel cheated by this. You sign a lease thinking you are partnering with an operator to share the bounty of the land. Then you find out they lobbied the state to carve out a massive secondary revenue stream entirely for themselves.

But from a purely factual standpoint, the state made a calculated policy decision. They wanted to protect the state’s fresh water supply. The fastest way to force oil companies to stop using fresh water was to make it highly profitable for them to recycle their wastewater. Giving operators the exclusive right to sell produced water was the carrot the state used to achieve a major conservation goal. Landowners just became collateral damage in that transaction.

We see this kind of legislative shift happen constantly. The rules of mineral ownership are not static. The state can, and does, change the definition of what you own and how you get paid.

It is the same legal maneuvering we see happening right now with underground storage rights. As we noted in Your Minerals Aren’t the Target — Your Pore Space Is, operators and carbon capture companies are actively trying to figure out how to monetize the empty rock beneath your feet without paying you for it. The produced water situation is just an earlier, highly successful version of that exact same playbook.

Knowing What You Own

Managing family mineral rights today requires a lot more than just waiting by the mailbox for a check. The industry is getting incredibly efficient at extracting value from every possible angle, and they employ very smart attorneys to ensure they keep as much of that value as legally possible.

If you own minerals in New Mexico, particularly in the Delaware Basin, your operator is almost certainly recycling and transferring water. You will not see a dime of it, and because of the 2019 Produced Water Act, there is no legal mechanism to fight for it. It is just another reality of modern oil and gas law. (And if you own minerals under state lands, the rules get even more complex, which we break down in New Mexico State Trust Land Minerals: The “Third Regime” Nobody Understands).

Dealing with these shifting goalposts can be exhausting for families, especially when the minerals were inherited and the original lease was signed decades ago by a grandparent. You find yourself managing an involuntary partnership with a corporation that has a massive legal advantage.

We talk to families every week who are tired of playing defense. They are tired of tracking legislative changes, deciphering check stubs, and wondering what the operator is going to lobby for next. Sometimes, stepping away from the complexity and converting that uncertain future into a clean, lump-sum asset makes the most sense for a family’s peace of mind.

Whether you intend to hold your minerals for the next fifty years or you are just starting to wonder what they might be worth today, the most important thing you can do is educate yourself. Know the math. Understand the laws governing your specific state. And if you ever want a clear, no-pressure look at what your assets are actually worth in today’s market, it is always worth a conversation to at least know your options.
