Sour-Gas Drilling in Verhalen, Texas: What Hydrogen Sulfide Is Doing to Your Family — and What the Law Says About It
You wake up with a headache so heavy it feels like something is pressing on your skull from the inside. The house smells like rotten eggs. Your child’s nosebleeds have become routine. Your asthma — or your spouse’s — is worse than it has ever been, and you live a mile from a well that the company promised would never send gas into your home. If you are reading this from a kitchen table in Reeves County, or from a house you fled to Fort Davis, or from anywhere in the Permian Basin where a drilling rig appeared on the horizon and your health started falling apart — you are not imagining it, you are not alone, and you are not the first family this has happened to.
We are Attorney911 — The Manginello Law Firm. We handle toxic exposure cases across Texas, and we have built this page for one reason: to tell you, in plain language, exactly what hydrogen sulfide does to the human body, why the state agency that was supposed to protect you didn’t, who can be held responsible in a Texas courtroom, what your case is worth, and what you need to do right now before the evidence that proves it disappears. This is legal information, not legal advice. Nothing here is a guarantee. But every word is written by a trial team that knows how these cases are built — because we build them.
The situation in Verhalen is not an isolated complaint. Public reporting and independent analysis have documented that more than 10,000 wells in Texas sour-gas fields — over half of the 19,000 total wells surveyed — lacked the required hydrogen sulfide paperwork on file with the Railroad Commission. Nearly 2,000 wells without proper H2S documentation were nonetheless granted flaring permits. The agency that regulates oil and gas drilling in Texas, by its own design, does not visit these sites to verify what operators report on their forms. It is a worksheet with checkboxes. And the gas that this system was built to contain is reaching families like yours.
That is the system. Here is what you can do about it.
What Hydrogen Sulfide Does to the Human Body
Hydrogen sulfide — H2S — is a colorless gas that occurs naturally in sour-gas oil fields like the ones surrounding Verhalen. It is produced when organic matter decomposes in the absence of oxygen, and it is released during drilling, production, and flaring operations in formations where the gas is trapped underground. ThePermian Basin sits on some of the most H2S-rich geology in North America. That is why drilling here is not just oil and gas work — it is hazardous-materials work, and the companies that do it know that.
The rotten-egg smell is the first thing most people notice. At very low concentrations — we are talking about parts per billion — the human nose is exquisitely sensitive to H2S. It is one of the most detectable substances on earth. That sensitivity is your body’s early warning system, and at the concentrations most people encounter near a drilling operation, it works. You smell it. You know something is wrong.
But here is the cruelest feature of this gas: at higher concentrations, the warning system fails. H2S causes olfactory fatigue — it paralyzes the very nerve that detects it. At around 100 parts per million, the rotten-egg smell disappears. The gas has not gone away. It has gotten worse. Your body has simply stopped being able to tell you. This is why people die from H2S in oilfields: the last thing they smell is nothing, and by then the concentration is already lethal. The Railroad Commission’s own safety regulations recognize this threshold — 100 ppm is the concentration that triggers heightened safety protocols and employee training requirements under the state’s H2S rules.
What the gas does to your body at the cellular level is block cellular respiration. H2S inhibits cytochrome c oxidase — the enzyme your cells use to process oxygen. In effect, it suffocates you from the inside, even when you are breathing air. At low to moderate concentrations, the effects are what the Franklins and families like them across the Permian Basin have described: headaches, dizziness, nausea, irritation of the eyes and respiratory tract, nosebleeds, and aggravation of existing conditions like asthma. At higher concentrations, the effects escalate to pulmonary edema — fluid in the lungs — and collapse. At the highest concentrations, H2S causes “knockdown,” a sudden loss of consciousness that oilfield workers call “the knockdown,” and death can follow within minutes.
For residents living near sour-gas operations, the exposure profile is different from a worker’s. You are not getting a single acute dose on a rig floor. You are getting chronic, intermittent exposure — the gas drifting over your property when the wind shifts, when flaring occurs, when a well is being completed or worked over. The headaches that wake you in the morning. The asthma that gets worse over months. The nosebleeds that become routine. These are the documented effects of chronic low-to-moderate H2S exposure, and they are what a board-certified toxicologist will connect to the drilling operation through exposure modeling, symptom-timeline correlation, and the medical literature on H2S health effects.
The defense will argue that your headaches have many causes. That your asthma was pre-existing. That the nosebleeds could be from the dry West Texas air. These are the standard toxic-tort defense arguments, and they are exactly why the medical record matters so much — a pulmonologist’s evaluation that documents the temporal relationship between your symptoms and drilling activity, combined with an environmental engineer’s air-dispersion model showing how H2S from the well would have reached your home, is how specific causation is proven when you cannot point to a number on a monitor that was never installed.
Who Is Responsible — The Defendant Map
A sour-gas exposure case in the Permian Basin is rarely one defendant. The operating entity — the company that drilled the well, promised the gas would not reach your home, and continued producing after the Railroad Commission temporarily shut it down — is the primary target. But the full defendant universe is wider, and identifying every responsible party is the difference between a case that fully compensates your family and one that leaves money on the table.
The operating entity / well operator. In the Verhalen situation, this is a Canadian energy company that drilled sour-gas wells within approximately one mile of the residence. The operator owed a duty to conduct its drilling operations with reasonable care and to prevent H2S migration onto neighboring properties. Its breach — the failure to contain H2S despite assurances, the continued production after a regulatory shutdown, the possible underreporting of concentrations — is the spine of the negligence claim. If this entity is a subsidiary of a Canadian parent, the parent’s assets may be reachable, and the foreign corporate structure adds both complexity and leverage to the case.
The midstream / pipeline operator. If H2S migrated through pipeline infrastructure or venting rather than solely from the wellhead, the midstream entity handling transport and processing of the gathered sour gas may share liability. These entities are identified through Railroad Commission pipeline and gathering-line records — the same database that tracks who holds permits for the infrastructure moving gas from the well to the processing plant.
The flaring-permit holders. Flaring of sour gas releases H2S and methane directly into the atmosphere. Operators who flared without proper H2S forms on file — and the reporting found nearly 2,000 such instances — face not only negligence per se claims for operating outside regulatory compliance but also punitive exposure if the underreporting was willful.
The Railroad Commission and TCEQ. We are asked whether the agencies themselves can be sued. The honest answer is that sovereign immunity under the Texas Tort Claims Act makes this extraordinarily difficult. The state waives immunity only in narrow, specifically defined circumstances, and the agencies’ failure to enforce their own regulations — as opposed to an affirmative negligent act — generally does not clear the immunity bar. We do not promise that the agencies will be held accountable, because the law makes that unlikely. What we can do is use their regulatory framework as the standard of care the operating entity violated.
The corporate structure of energy defendants is designed to obscure responsibility. The entity that holds the well permit may be a subsidiary. The entity that employs the drilling crew may be a contractor. The entity that profits from the gas may be a parent three entities up the chain. Each layer is a separate investigation, and each must be identified through Railroad Commission well-permit records, lease assignments, and Secretary of State filings — not from the name on the sign at the wellsite.
The Company’s Playbook — What They Will Do to Fight You
Lupe Peña spent years inside a national insurance-defense firm before he came to this side of the table. He sat in the rooms where adjusters and their software decided how to deny, delay, and devalue claims from people exactly like you. He knows the plays because he ran them. Here are the ones you will face in a sour-gas exposure case, and here is how each one is answered.
Play 1: “We were operating under a valid permit.” The company will point to its Railroad Commission permit and argue that it was authorized to drill and produce. The counter is simple and the law supports it: a permit is permission to operate, not a license to negligently release hazardous gas onto your property. The permit does not immunize the company from the consequences of its own failure to contain H2S. A drilling permit is not a waiver of your right to sue for the harm the drilling caused.
Play 2: “You can’t prove H2S was at harmful levels in your home.” This is the defense’s strongest card, and it is exactly why the evidence-preservation work matters so much. If no ambient air monitor was installed at your residence, the company will argue that you cannot prove the concentration you were exposed to. The counter is a three-part combination: (1) an environmental engineer’s air-dispersion model showing how H2S from the well would have reached your home under the prevailing conditions, (2) the temporal correlation between your documented symptoms and drilling activity, and (3) the company’s own H2S concentration data from the well — which it was legally required to report and which discovery can force into the open. You do not need a number from a monitor in your living room if the modeling, the medical timeline, and the well data all point the same direction.
Play 3: “Your health problems have other causes.” The defense will argue that headaches, asthma, and nosebleeds are common conditions with many potential causes — allergies, dry climate, stress, pre-existing conditions. This is where the eggshell-plaintiff doctrine and the medical record intersect. Under Texas law, the defendant takes the victim as found — if you had asthma before the drilling started and H2S aggravated it, the company is responsible for the aggravation. And a pulmonologist who documents the timeline — symptoms onset or worsening correlating to drilling activity — provides the specific causation link that defeats the “many causes” argument.
Play 4: “You signed a release when you sold your property.” If you sold your land to the drilling company, the company will produce the sale documents and argue that all claims were released. The counter depends on the specific language of the agreement — did it release personal-injury claims, or only property claims? Were injury claims expressly reserved? Was the release knowing and voluntary, or was it part of a distress sale negotiated under the pressure of ongoing toxic exposure? This is a threshold legal question that requires immediate review of the sale documents by an attorney who reads releases for a living.
Play 5: Delay. The most effective play in any toxic exposure case is the clock. The company knows that Texas imposes a two-year statute of limitations on personal injury claims. It knows that evidence degrades. It knows that memories fade and witnesses move. The longer the case sits, the weaker it gets. The counter is speed — a preservation letter that freezes the evidence, medical evaluation that documents the harm, and a lawsuit filed within the limitations period that forces the company to engage on your timeline, not its own.
The Proof Story — How a Sour-Gas Exposure Case Is Actually Built
Here is the chronological walk of how a case like this moves from your kitchen table to a courthouse in Reeves County.
Week one: the preservation demand. The day you call, a litigation-hold letter goes to the operating entity and any midstream or pipeline operators identified through Railroad Commission records. The letter demands preservation of all H2S concentration data, internal communications about the well and about your complaints, safety reports, flaring records, site-perimeter monitoring data, and the documents underlying the company’s assurance that H2S would not enter your residence. A separate open-records demand goes to the Railroad Commission for well permits, sour-gas forms, inspection records, and any correspondence related to the temporary shutdown. A third demand goes to TCEQ for complaint records and any air-quality data from the Verhalen area. These letters are not courtesy — they are the legal mechanism that converts routine document destruction into sanctionable spoliation if the company lets evidence die after receiving them.
Weeks two through four: the medical and expert foundation. If you are still experiencing symptoms, you are evaluated by a pulmonologist — not your family doctor, a specialist who can document respiratory function, diagnose H2S-related injury, and create a medical record that ties your symptoms to the exposure timeline. Your medical records are pulled and organized chronologically against the drilling timeline. A board-certified toxicologist is engaged to provide general causation testimony — the medical literature establishing that H2S exposure at the concentrations modeled causes the symptoms you experienced. An environmental engineer is engaged to build the air-dispersion model — using meteorological data, well location, H2S concentration data from the operator’s own reports, and the topography of the Permian Basin terrain between the well and your home.
Months one through three: the property sale review and entity identification. If you sold your property to the company, the sale documents are reviewed for release language. This is a threshold issue — if personal-injury claims were released, the case may need to pivot to current residents who are still exposed and have not sold. If claims were reserved, or if the release is narrowly drawn to property only, the case proceeds. Through Railroad Commission records and Secretary of State filings, the operating entity’s corporate structure is mapped — the well permit holder, the parent company, any affiliated entities, and the insurance tower behind each.
Months three through twelve: discovery and depositions. The lawsuit is filed in the appropriate venue — Reeves County falls under the 83rd Texas Judicial District and the Pecos-based 143rd Judicial District, and venue strategy must account for the reality that oil and gas is the economic lifeblood of the region. The company’s internal H2S data comes out in discovery. Its communications about your complaints come out. The basis for its assurance that the gas would not enter your home comes out. The depositions of the company’s safety director, its drilling supervisor, and the individuals who made the decision to resume production after the regulatory shutdown are where the punitive-damages case is built — under oath, with documents in front of them, explaining the choices they made.
The number at the end is built from all of it — the medical costs, the property loss, the pain and suffering, the lost earning capacity, the medical monitoring, and the punitive exposure that a jury’s finding of gross negligence unlocks. That number is not a guess. It is an arithmetic problem assembled from the life-care planner’s cost stream, the forensic economist’s present-value calculation, and the trial team’s assessment of what a jury in this venue will do with this evidence against this defendant.

The Bottom Line
The Permian Basin is the engine of Texas oil and gas production, and the people who live there — in Verhalen, in Pecos, in every unincorporated community where a drilling rig appeared on the horizon — have a right to be safe in their homes. A company that drills in a known sour-gas field has a duty to contain the gas it releases. A company that tells you the gas will never reach your home has made a promise it can be held to in court. And a regulatory system that relies on self-reporting and unchecked boxes is not a defense — it is the reason private litigation exists.
If hydrogen sulfide from sour-gas drilling has harmed your health, forced you from your home, or made the place you planned to spend the rest of your life unlivable, you have rights under Texas law. The evidence is on a clock. The company has lawyers. You should too.
