If Your Family Is Breathing Hydrogen Sulfide from Oil Operations in Odessa, This Is What the Law Says — and What the Companies Hope You Never Find Out
You wake up to the smell of rotten eggs. Your children have headaches again. Your toddler is nauseated. Across the street, a flare burns gas in a curling flame from a pipe jutting thirty-five feet into the West Texas sky, and behind it sit weathered 500-barrel tanks storing oil and water pumped from wells that have been here longer than most of the houses. You have called the state. You have filed complaints. An inspector came out, found the gas leaking from a damaged tank hatch or an unlit flare, wrote it up, and left. The company made a piecemeal repair. The gas kept leaking. That is not a failure of your persistence. It is a feature of a system designed to protect the operator’s economics, not your family’s lungs.
What the state’s own monitoring equipment has documented outside homes in Odessa — in Ector County, in the heart of the Permian Basin — is not a close call. State air analysts were hit with hydrogen sulfide so concentrated inside their monitoring van that their hearts raced, their heads split, and they became nauseated. They fled. Their internal notes called the levels “insanely high.” One reading outside a family home reached 62 parts per million — stronger than the maximum level the Occupational Safety and Health Administration allows for oilfield workers who are trained, equipped, and consenting to the risk. Another reading hit 81 parts per million in a family’s yard at midnight, approaching the 100 parts per million threshold the government classifies as “immediately dangerous to life or health.” The Texas residential limit is 0.08 parts per million averaged over thirty minutes. Your children are breathing air that has tested at levels dozens to over a thousand times that number. Nobody told you. Nobody stopped it.
We are Attorney911 — The Manginello Law Firm, PLLC. We handle toxic tort claims and catastrophic injury cases across Texas, and this page is for the one person reading at 2 a.m. whose family has been breathing this poison while the company across the street keeps flaring and the state keeps writing violations that lead to nothing. What follows is everything the senior trial attorney on our team knows about how a case like this is built — the law, the medicine, the companies, the money, the evidence that is disappearing while you read this, and the playbook the operator and its insurer will run against your family. You will know more when you finish this page than the company’s representative wants you to know. That is the point.
What Hydrogen Sulfide Does to Your Body — and Why “It Just Stinks” Is a Lie
Hydrogen sulfide — H2S, “sour gas” — is a colorless gas that smells like rotten eggs at low concentrations. That smell is your body’s warning system. But that warning system has a deadly flaw: at higher concentrations, H2S paralyzes the olfactory nerve. You stop smelling it. The silence is not safety. It is the moment the gas becomes most dangerous, because the alarm that was telling you to leave has been disconnected by the gas itself.
Here is the mechanism, explained the way the toxicologist on our team would explain it to a jury. H2S is a broad-spectrum poison. It crosses from the lungs into the bloodstream and attacks the body’s cellular energy systems — the same machinery that keeps your nerves firing, your heart beating, and your brain thinking. At the concentrations the state measured outside homes in Odessa, the effects are immediate and recognizable: racing heartbeat, headache, nausea, eye and nose irritation, coughing. Those are the symptoms the state’s own air analysts experienced when they fled the monitoring van. They are the symptoms families across the Odessa neighborhoods describe. They are not imagined. They are not coincidental. They are the expected medical consequences of breathing a cellular poison at the levels the state’s own equipment recorded.
But the deeper harm — the one that terrifies parents — is what chronic, low-level exposure does over months and years. Studies have linked long-term H2S exposure to neurological problems. An EPA toxicologist’s report, cited in the federal criminal prosecution of an Odessa-area oil operator for H2S-related deaths, identified the effects of chronic low-level exposure as including fatigue, poor memory, personality changes, hallucinations, shortness of breath, and increased emergency room visits. Those are not abstract risks in a medical journal. They are the exact symptoms parents in Odessa are watching their children develop — the headaches that keep a thirteen-year-old soccer player off the field, the nausea that wakes a mother at 2 a.m., the rashes, the coughing, the asthma, the fog that settles over a household that has been breathing sour gas for years while the state wrote violation notices and the company replaced a hinge.
Your children are not “fine for now.” Developing respiratory and neurological systems are uniquely vulnerable to chronic toxic exposure. The damage can be silent, cumulative, and latent — meaning the full extent of what this gas has done to your child’s lungs, brain, and future may not declare itself for years. This is why medical monitoring is not alarmism. It is responsible precaution backed by federal science.
The Scale of What Is Happening: 78,000 People and 88 Schools
This is not one family’s problem. Across Texas, more than 54,000 wells are associated with hydrogen sulfide concentrations high enough to be classified as “immediately dangerous to life or health” if the gas were to leak and people were exposed directly. An estimated 78,000 people live within a half-mile of those wells. Eighty-eight schools sit in the same footprint. In the Permian Basin alone, at two monitored sites, gas levels exceeded the state limit 1,590 times since the state started measuring in 2020.
At Murry Fly Elementary School in Odessa — where a statue of a spurting oil dicker displays the school’s nickname, the Oilers — a state monitoring station near the playground has recorded hydrogen sulfide above the state limit 185 times since 2020. The principal said he was never warned. The school district has no records it was ever notified of elevated levels by state officials. At Noel Elementary School, 800 feet from oil storage tanks, a parent called 911 because of the strong smell of H2S. The school has an H2S alarm system, but the principal does not know what concentration would set it off. The system does not log the levels it detects — so nobody knows to what concentration of toxic gas the students have been exposed while sitting at their desks.
A leading researcher on H2S, the dean of science at York University in Toronto, put it plainly: if people live within a half-mile radius of these leaks, they will be affected. An associate professor at Texas A&M who studies oil-field air pollution called the high levels in residential areas “shocking” and said nobody should be living close to the facilities. When a monitor picks up the gas at one level, that suggests it is swirling through the community at possibly much higher levels elsewhere.
Who Is Responsible: The Companies, the Corporate Structure, and the Money Trail
Understanding who to hold accountable in a case like this requires understanding how oil operations in the Permian Basin are structured — because the company whose name is on the tanks is often not the only entity whose decisions created the danger, and the entity with the deepest pockets is sometimes the one that made a single decision years ago that forced the pollution into your neighborhood.
The operator across the street. The oil and wastewater storage tanks and the flare across from the family home in Odessa were operated for years by Cambrian Management, a company co-founded in 2001 that has drilled and operated hundreds of wells in the Permian Basin. State inspectors documented Cambrian leaking H2S in violation of Texas regulations at least 14 times between 2015 and 2021 near the elementary school alone, and repeatedly at the site across from the family home. The company’s own 2001 filing with the Railroad Commission acknowledged that a catastrophic release of gas from that production site could overlap public areas with potentially life-threatening levels of H2S. TCEQ fined Cambrian $7,600 at one point. The company never complied with the agency’s order. The agency did not follow up — until a journalist asked about it in 2024, at which point TCEQ discovered the noncompliance and sent a follow-up letter. The agency currently lists the company’s compliance record as “satisfactory.”
The company’s co-owner, who retired from day-to-day operations in 2023, admitted in a published interview that living near the smell of H2S is annoying but said he sees it as more of an irritant than a safety concern. He said he “never lost an ounce of sleep about somebody getting hurt” because the volumes were low. He said it “stinks really bad” and “if it didn’t stink, we wouldn’t get any complaints.” This is the same person whose company filed a flaring permit application with the state in which it argued that the alternative to flaring — shutting down the site — would cause “economic waste since oil will go unproduced.”
The company’s own permit application told the state, in writing, that it chose to keep flaring gas into the residential neighborhood because stopping would mean leaving oil in the ground. That is not a safety analysis. That is a profit analysis. And it is an admission against interest in a government filing.
The current operator. In 2023, day-to-day management was transferred to Octane Energy. The managing partner of Octane acknowledged that the facilities are aging and that retrofitting them “may never actually pay for itself.” That sentence — spoken publicly, on the record — is a corporate executive admitting that his company knows the equipment is dangerous, knows what it would take to fix it, and has calculated that the cost of human health is not worth the capital investment. In a courtroom, that is called gross negligence. In Texas, gross negligence is the threshold for exemplary — punitive — damages.
The midstream company that forced the flaring. This is the money trail that most people miss. Cambrian used to pipe excess gas from its wells to a processor. In 2017, the company that operated the pipelines — DCP Midstream, now part of Phillips 66 — stopped accepting Cambrian’s gas stream, citing a “high level of operational risk.” That refusal forced Cambrian to begin flaring all its gas — the continuous billowing flame outside the family home. DCP Midstream’s decision was a proximate cause of the ongoing H2S releases into the community. Phillips 66 is a tier-one corporate defendant with the balance sheet and insurance tower that small independent operators like Cambrian often lack. The decision to refuse the gas stream was made with full knowledge that the alternative — uncontrolled flaring next to homes — would release H2S into a residential area. Following the money upstream from the small operator to the midstream giant is how a case that might be worth hundreds of thousands against a thinly capitalized LLC becomes a case worth millions against a Fortune 500 company.
The operator facing criminal prosecution. A separate Odessa-area operator, Aghorn Operating, faces federal criminal charges under the Clean Air Act and OSHA for the 2019 deaths of Jacob and Natalee Dean, who were killed by a cloud of highly concentrated hydrogen sulfide at an Odessa pump house. Federal prosecutors alleged a scheme to “enrich themselves by maximizing the production of oil at Aghorn while minimizing costs.” The prosecution cited a report by an EPA toxicologist warning that chronic, low-level exposure to the gas includes fatigue, poor memory, personality changes, and hallucinations. Prosecutors also alleged that “the hazardous plume traveled beyond the facility at levels sufficient to adversely impact public health” — meaning people living up to a mile away could have been exposed to enough gas to cause health problems. That criminal prosecution creates parallel evidence: the government’s own toxicological findings, the theory of cost-minimizing endangerment, and the finding that the plume reached beyond the fence line. All of it supports civil liability against operators with identical practices.
The operator near the school with the conflict of interest. In Breckenridge, Texas, a company called Petex operates wells and tanks adjacent to South Elementary School. Railroad Commission inspectors found H2S venting toward the school playground in at least six inspections from 2016 to 2019, with additional violations in 2021 through 2023. Petex’s chief operating officer is the president of the Breckenridge school board. That is not a footnote. It is a conflict of interest that, in litigation, becomes evidence of why the danger was tolerated — the person responsible for the tanks had institutional influence over the institution that was supposed to protect the children breathing the gas.
The Regulatory Failure: Two Agencies That Knew and Did Not Act
The regulatory story is not just background. It is evidence of notice — proof that the operators and the state both knew the danger existed and chose not to stop it.
The Railroad Commission of Texas regulates the oil industry under Rule 36, the safety regulation enacted after the 1975 Denver City disaster that killed nine people, including two teenage girls, when an oil-field leak of hydrogen sulfide overtook them as they tried to flee. Victims were found slumped in their vehicles. Rule 36 requires operators in high-H2S areas to measure concentrations, train employees, post warnings, and in some cases monitor for leaks. But the former statewide H2S coordinator at the Railroad Commission — a man who spent 30 years patrolling oil fields and whose personal H2S alarm would go off at someone’s front door — said the rule “needs some teeth and some muscle and blood in it.” He said it has not been substantively updated in nearly 50 years. He said he was hampered in his ability to stop companies from releasing toxic gas near people. At most, he could order short-term shutdowns and require companies to flare. But the flares themselves would sometimes go out, releasing more gas freely into the air.
The Texas Commission on Environmental Quality enforces the state ambient air standard for H2S at 0.08 ppm averaged over 30 minutes in residential areas. But the agency broadly disregards exceedances. It closes complaints after a single visit if inspectors do not detect the gas at the precise time they arrive — even though levels fluctuate with weather, wind, and oil operations, and are often worse at night when inspectors are not there. The agency has not added any sites to its Air Pollutant Watch List since 2007, ignoring the shale boom that has brought an explosion of oil and gas activity across the state since then. The agency’s spokesperson said “odorous levels are not necessarily harmful levels” and that health effects “should go away when the individual is no longer smelling the chemical.”
That statement — that the harm goes away when the smell goes away — is medically false. It contradicts the EPA toxicologist’s findings. It contradicts the peer-reviewed literature on chronic H2S exposure. It contradicts the agency’s own staff behavior, who evacuate when gas levels are far lower than what the agency claims is harmful. It is a position designed to minimize enforcement, not to protect public health. And it is the position the oil companies will adopt as their defense in your case.
Your Legal Rights Under Texas Law
Texas law provides multiple paths to hold oil operators accountable for releasing toxic gas into residential communities. Each path addresses a different aspect of the harm, and a well-built case pleads them together.
Private nuisance. Texas recognizes a cause of action for private nuisance — a substantial and unreasonable interference with your use and enjoyment of your property. The continuous H2S emissions, the unlit flare releases, the persistent rotten-egg odor, the nighttime spikes that wake your family with nausea — documented over years of complaints and state inspections — are the textbook facts of a private nuisance claim. Your home is your property. The company across the street has turned your yard into a place where your children cannot safely play. Texas law says that is not something you have to tolerate.
Public nuisance. When the harm extends to the community — to the 78,000 people estimated to live within a half-mile of dangerous wells, to the 88 schools in the footprint, to the neighbors who described the smell as “overpowering” but were too afraid to file a complaint — the interference becomes a public nuisance. It is an unreasonable interference with a right common to the general public: the right to breathe air that does not poison you.
Trespass. Texas courts have recognized trespass claims for intangible invasions — including gases and fumes — when the intrusion is substantial and causes demonstrable harm. H2S gas particles crossing the property line and entering your home and yard are a trespass. The gas does not need to damage the structure of your house. It needs to enter it, cause harm, and be traceable to the defendant’s conduct. The state’s own monitoring data — showing the gas at your property line at levels exceeding workplace safety standards — is the proof.
Negligence. The operators failed to maintain tank hatches, seals, flare ignition systems, and underground pipelines in reasonable condition. They failed to monitor for leaks. They chose flaring over safe gas processing for economic reasons. They failed to repair known corroded equipment despite repeated state citations. Each of those failures is a breach of the duty of reasonable care that an oil operator owes to the people living near its facilities.
Negligence per se. Violations of Texas Railroad Commission Rule 36 and TCEQ air quality standards constitute negligence per se — meaning the violation of the safety regulation itself is the negligence, and you do not need to separately prove that the operator acted unreasonably. The operator was repeatedly cited for releasing H2S in violation of state regulatory limits designed to protect public health. Those citations are the negligence.
Strict liability / ultrahazardous activity. The storage and handling of H2S at concentrations exceeding 186,000 parts per million — a substance classified as immediately dangerous to life and health — in close proximity to residential areas may constitute an abnormally dangerous activity. The gas is corrosive, toxic, and inherently incapable of being safely contained in aging infrastructure near homes. Under strict liability, you do not need to prove the operator was careless. You need to prove the activity was abnormally dangerous and that it caused your harm.
Gross negligence and exemplary damages. This is where the case transforms from a compensation claim into a punishment claim. Texas allows exemplary — punitive — damages when the plaintiff proves by clear and convincing evidence that the defendant acted with fraud, malice, or gross negligence. Gross negligence means the defendant acted with conscious disregard of a known extreme risk. The evidence here is devastating: 14-plus documented violations over years with only piecemeal repairs; the company’s own admission that it “never lost an ounce of sleep about somebody getting hurt”; the 2001 filing acknowledging catastrophic release could expose public areas to life-threatening levels; the economic-choice documentation showing flaring was chosen over facility upgrades because retrofitting “may never actually pay for itself”; DCP Midstream’s refusal to accept the gas stream for safety reasons followed by the choice to flare into a residential area. Each of these facts is a brick in a wall of conscious disregard. Texas caps exemplary damages by statute, but the cap is tied to the economic damages — which means the more medical bills, lost wages, and property devaluation you can prove, the higher the punitive ceiling climbs.
Medical monitoring. Residents with documented chronic exposure to H2S at levels exceeding state limits and OSHA worker standards are entitled to ongoing medical surveillance to detect latent neurological, respiratory, and other health effects. This is an evolving area of Texas law — whether medical monitoring is recognized as a standalone cause of action or requires present physical injury is a question that depends on the controlling authority in the relevant appellate jurisdiction. What is not in dispute is that the need is real: the EPA’s own toxicologist identified the latent effects, and the scientific literature documents them. A wrongful death claim and survival action would apply if exposure contributed to a death, as in the Dean family’s case.
The Texas Statute of Limitations — and Why the Discovery Rule May Save Your Claim
Texas imposes a two-year statute of limitations on personal injury claims. For most injuries, the clock starts on the date of the injury. But toxic exposure cases are different. The harm from chronic H2S exposure is cumulative and latent — you may not connect your child’s headaches, your own nausea, or your parent’s breathing problems to the gas from the facility across the street until years after the exposure began.
Texas law recognizes the discovery rule for latent injury and disease: the cause of action does not accrue — the clock does not start — until the plaintiff knew or by reasonable diligence should have known of the injury and its cause. In a community where the state itself did not tell residents that H2S levels outside their homes had soared to 82 times the legal limit, where the principal of an elementary school was never warned that a monitor on his playground had recorded 185 exceedances, where the agency charged with protecting public air quality told people the smell was harmless — the argument that residents could not have known, and should not have been expected to know, is strong.
But do not assume the discovery rule is automatic. Some statutes of repose can cut off claims even before discovery. The specific deadline that applies to your family depends on when the exposure occurred, when you first connected your health problems to the gas, and the particular legal theory you pursue. This is not a question to answer by reading a website. It is a question to answer by calling a lawyer who handles toxic tort cases in Texas and can evaluate your specific timeline. The two-year clock is real, and it is unforgiving once it starts.
What a Case Like This Is Worth
Every case is different, and the value of any specific claim depends on the severity of provable injury, the number of family members affected, the duration and concentration of exposure, the defendant’s collectibility, and the venue. What follows is the framework we use to evaluate a toxic tort case involving H2S exposure from oil operations, based on the categories of harm Texas law recognizes.
For an individual family — say, a household of four to six people living across from a facility documented by state inspectors as leaking H2S over multiple years, with children whose developing systems are uniquely vulnerable, with property that has lost value because of the industrial encroachment and the stigma, with medical monitoring needs, and with strong evidence of the operator’s conscious disregard — the case value can range from approximately $2 million to $15 million, depending on the severity of provable injury and the defendant’s ability to pay.
For a community mass tort — if framed as a multi-plaintiff action representing the Odessa neighborhoods near the leaking facilities, the families of children at the affected schools, and the broader exposed population — aggregate exposure could reach $50 million to $250 million or more, particularly if punitive damages are supported by the pattern of conscious disregard across multiple operators and the regulatory failure.
For a wrongful death case — such as the Dean family, where two people were killed by acute H2S exposure at an oil facility, with a federal criminal prosecution establishing corporate malfeasance — the case value can range from $10 million to $40 million or more.
Several factors increase the value of these cases. Phillips 66 / DCP Midstream provides a deep-pocket defendant with a direct causal link — its 2017 refusal to accept the gas stream forced the flaring. The Aghorn criminal prosecution creates parallel-evidence value: the EPA toxicologist’s findings, the government’s theory of cost-minimizing endangerment, and the finding that the plume traveled beyond the fence line. The state’s own monitoring data provides irrefutable exposure documentation — this is not a case where the plaintiff has to prove the gas was there; the government already measured it. Infrared video evidence — showing otherwise-invisible plumes of H2S escaping from tanks and unlit flares — is visually devastating for juries. And the children-in-schools narrative — 88 schools in the footprint, 185 exceedances at one playground, a principal who was never told — drives settlement pressure that transcends the individual-family dispute and frames the case as a community-safety crisis.
Several factors decrease value. Cambrian Management is a small independent operator with uncertain insurance depth and an uncertain asset profile. Causation for chronic low-level H2S health effects is contested by TCEQ and will require robust expert testimony. Texas tort reform provisions and venue in oil-dependent Ector County create headwinds. And the statute of limitations may bar older exposure periods. Honest evaluation requires confronting all of these.
Past results depend on the facts of each case and do not guarantee future outcomes.
The Evidence That Is Disappearing Right Now
This is the section that determines whether your case is built on paper or built on guesses. In a toxic tort case, the evidence exists in records held by multiple entities — and most of those records are on a clock. Some are already approaching the end of their legal retention. Some are being lost because the operator is transferring management and personnel are turning over. The preservation letter that freezes these records goes out the day you call a lawyer — not the day you file suit, and not the day you “decide whether it’s worth it.”
TCEQ mobile monitoring van data and internal communications. The state’s own monitoring data — the readings that documented “insanely high” H2S levels of 62 to 82 ppm near the family home, the internal emails where regulators acknowledged the severity and their own enforcement failures — are government records subject to retention schedules. Internal emails and field notes may be purged per agency record-disposition policies. These must be requested immediately through the Texas Public Information Act.
Railroad Commission inspection files and violation records. These document at least 14 violations at the facility near the elementary school between 2015 and 2021, six inspections showing H2S pluming toward the Breckenridge school playground, and repeated violations at the Aghorn and Petex sites. Older files may already be at disposition threshold. Request immediately.
Infrared video footage of gas leaks. TCEQ and the Railroad Commission obtained infrared video showing otherwise-invisible H2S plumes escaping from tanks and unlit flares adjacent to homes. This footage converts abstract parts-per-million numbers into visual proof a jury can see. Additional footage may exist in agency files or from continued monitoring. Request all infrared imaging through public records.
Cambrian Management maintenance records, flare repair logs, and tank inspection reports. These show whether the company performed regular maintenance, knew of corrosion and equipment failures, and made piecemeal rather than systematic repairs. This is critical for gross negligence and punitive damages. Cambrian transferred operations to Octane Energy in 2023. Personnel turnover and the operational transition create a high risk of document loss, destruction, or spoliation. A preservation letter to both Cambrian and Octane must go out immediately.
Text messages between residents and company representatives. The family’s text exchanges with a company representative — asking for help, reporting the smell, photographing the unlit flare — are direct admissions and document the company’s actual knowledge of ongoing leaks and resident suffering. The company-side text logs may be deleted during routine phone replacement cycles. Demand preservation of all mobile device communications.
DCP Midstream / Phillips 66 records regarding the 2017 refusal. The decision to refuse Cambrian’s gas stream — and the citation of a “high level of operational risk” — directly forced Cambrian to begin flaring adjacent to residential property. Corporate records from 2017 may be subject to routine document retention policies, and the DCP / Phillips 66 merger may have triggered records consolidation or destruction. A preservation letter is needed.
Independent H2S monitor data. The monitoring data collected in the family’s yard — which detected gas levels above the state limit on more than half the days recorded, with a peak of 81 ppm — and the family’s personal H2S alarm video from 2019 provide an earlier baseline. Secure the raw data files and metadata from the monitoring equipment and preserve the original video.
Medical records. Complete medical histories are needed to establish baseline health status, the temporal correlation between exposure events and symptom onset, and documented treatment for H2S-related conditions. Earlier medical visits may not have noted H2S exposure as the cause — obtain complete histories and have treating physicians correlate symptoms with the exposure timeline.
School district records. Records regarding H2S alarms, shelter-in-place events, and parent notifications — including Noel Elementary’s 2016 shelter-in-place, the alarm trigger history, the failure to log H2S concentrations, and Murry Fly Elementary’s 185 exceedances without principal notification — document school exposure to children. School districts may purge records per local retention schedules. Request immediately under the Texas Public Information Act.
The company’s flaring permit application. The application in which the company stated that shutting down rather than flaring would “result in economic waste since oil will go unproduced” is a government record. Obtain a certified copy. This is a direct admission that profit motivated continued pollution.
Employee testimony. Former pumpers, field workers, and operational staff have firsthand knowledge of equipment failures, repair practices, management awareness of leaks, and whether H2S monitoring was conducted as required by Rule 36. They know whether fixes were permanent or temporary. Personnel turnover is high in oilfield operations. The company’s co-owner has retired. The operational transfer to Octane creates turnover. Former employees relocate or forget details. Identifying and deposing key witnesses within months — not years — is critical.
What the Company and Its Insurer Will Try — and How Each Play Is Countered
The oil operator and its insurance representative are not your friends, no matter how friendly the text messages feel. Every communication is building the company’s defense file. Here are the plays they will run, and the counter to each.
Play 1: “The odor is not harmful.” The company will adopt TCEQ’s line — that odorous levels are not necessarily harmful levels, and that health effects “should go away when the individual is no longer smelling the chemical.” The counter: the state’s own air analysts became sick at levels the agency claims are harmless, and the EPA toxicologist’s report — cited in a federal criminal prosecution — identifies chronic low-level exposure effects including neurological damage. The agency’s own staff behavior contradicts its public statements. A board-certified toxicologist testifies that chronic H2S exposure at the documented levels causes the exact symptoms the family reports. The “it’s just a smell” defense collapses under the state’s own monitoring data.
Play 2: “It could be something else.” The company’s co-owner already telegraphed this defense publicly: “It’s possible that someone with asthma might be affected by the H2S, or it could be something else.” The counter: specific causation is established through dose reconstruction using the state’s own monitoring data, the temporal correlation between exposure spikes and symptom onset, the absence of alternative sources in the immediate vicinity, and the scientific literature linking chronic H2S exposure to the plaintiffs’ specific symptom profile. The eggshell-plaintiff doctrine — which Texas follows — means the defendant takes the victim as found. A child with asthma who is worsened by H2S does not have a weaker case. The defendant’s gas made a vulnerable child sicker. That enlarges damages, it does not erase them.
Play 3: “We fixed it every time.” The company will point to its piecemeal repairs — the replaced tank hatches, the relit flares, the fixed spark plugs — and argue it acted responsibly. The counter: the repairs were temporary by the company’s own admission. The flare kept going out. Birds nested and broke the spark plug. The underground pipeline was leaking. The state inspector wrote that “the tanks continue to leak” and that the site had “documented many violations over the past month.” A pattern of repeated violations followed by repeated temporary fixes followed by repeated violations is not diligence. It is evidence of conscious disregard — the exact standard for gross negligence and exemplary damages.
Play 4: “Our volumes are too low to hurt anyone.” The company’s co-owner said he “never lost an ounce of sleep about somebody getting hurt, because I knew our volumes were so low.” The counter: the state’s own monitoring van measured 62 to 82 ppm in the neighborhood — levels that exceeded OSHA worker-safety standards. The Texas A&M professor who studies oil-field air pollution said the measured levels were “crazy” and indicated leaks so large that if someone had been exposed closer to the source it could have been deadly. The volume argument is contradicted by the government’s own instruments.
Play 5: The “satisfactory compliance” dodge. TCEQ lists the company’s compliance as “satisfactory” despite years of documented violations and noncompliance with enforcement orders. The company will point to this designation. The counter: the “satisfactory” rating is an administrative artifact of an agency that closed complaints without investigation, failed to follow up on its own enforcement orders for years, and adopted a public position that the gas it was measuring at dangerous levels was harmless. The rating is not evidence of safety. It is evidence of regulatory failure.
Play 6: The quick-check with a release attached. At some point, a company representative or insurer may offer a modest payment — to “help with your medical bills” or “for the inconvenience” — with a release that, once signed, extinguishes every claim your family has, including future medical monitoring, including punitive damages, including the claims of your children who may not develop symptoms for years. Never sign anything presented by the operator, its representative, or any insurance adjuster without legal review. No release, no settlement, no access authorization. The text messages that feel like a helpful company representative responding to your complaints are building the company’s file. Everything you say can and will be used to minimize your claim.
The Permian Basin Context: Why This Happens Here
Odessa sits in Ector County, in the Permian Basin of West Texas — the most productive oil field in the United States, pumping more than 40% of the country’s oil. The region is naturally saturated with hydrogen sulfide. The shale boom of the past 16 years has tapped vast new quantities of oil, bringing explosive population growth and new residents into direct proximity with aging oil infrastructure that was built when nobody lived nearby. Homes, elementary schools, and oil storage tanks now coexist within hundreds of feet of each other. This is a land-use collision created by the industry’s expansion into residential areas — not by families choosing to live next to oil tanks, but by oil tanks continuing to operate as homes and schools were built around them.
Ector County is deeply oil-industry-dependent. Jury pools include oilfield workers, industry suppliers, and royalty recipients. That dynamic cuts both ways: there may be industry sympathy on a jury, but there is also intimate knowledge of how H2S dangers are managed — or not managed — in the field. An oilfield worker on a jury knows what it means when a flare is unlit. They know what H2S does. They know the company could have fixed the equipment and chose not to. That knowledge is an asset, not a liability, when the case is presented honestly.
Our firm has deep experience with the Permian Basin. We have spent years handling oilfield and industrial accident cases across Texas, and we know the region’s industries, its corridors, its courthouses, and the way oil operations intersect with the lives of the people who live among them. We also handle refinery and industrial accident cases that involve many of the same regulatory regimes — OSHA, the Clean Air Act, process safety management — that govern the facilities leaking H2S into your neighborhood.
What to Do If Your Family Has Been Exposed to H2S
First, protect your health. If you or a family member is experiencing acute symptoms — difficulty breathing, collapse, confusion, severe nausea — seek medical attention immediately. H2S exposure at high concentrations can be lethal. Tell the treating physician that you live near oil operations and have been exposed to hydrogen sulfide. Ask them to document the exposure in your medical record. If your child has chronic symptoms — headaches, coughing, rashes, nausea — take them to a doctor and make sure the record connects the symptoms to the residential proximity to H2S sources.
Second, document everything. Keep a daily log: the date and time of odor events, the wind direction, the symptoms each family member experiences, whether the flare across the street is lit or unlit, any visible emissions from the tanks. Photograph the flare when it is unlit. Photograph the tanks. Save every text message exchange with the company representative. Save every complaint you have filed with TCEQ or the Railroad Commission and every response you received. Request your complete medical records from every provider who has treated any family member for respiratory, neurological, or gastrointestinal symptoms.
Third, do not sign anything. Do not sign a release, a settlement, or an access authorization presented by the operator, Octane Energy, Cambrian Management, or any insurance representative. Do not give a recorded statement. Do not agree to let the company’s representative “inspect” your property. Do not accept a check with a release printed on the back. Everything the company does in the first weeks and months after you raise the issue is designed to limit its liability — not to help your family.
Fourth, call a lawyer who handles toxic tort cases. The preservation letter that freezes the company’s maintenance records, the state’s monitoring data, the infrared video, and the employee testimony goes out the day you call. Every day you wait is a day those records get closer to legal destruction. The evidence in this case is extraordinary — the state’s own instruments measured the poison in your air — but evidence does not preserve itself. It has to be demanded, in writing, by someone who knows what to demand and from whom.

Frequently Asked Questions
Can I sue the oil company for making my family sick with hydrogen sulfide gas?
Yes. Texas law provides multiple legal theories for holding oil operators accountable when they release toxic H2S gas into residential communities: private nuisance for the interference with your home, trespass for the gas entering your property, negligence for failing to maintain equipment, negligence per se for violating state safety regulations, strict liability for conducting an ultrahazardous activity near homes, and gross negligence — which opens the door to exemplary damages — when the operator knew of the danger and chose economics over safety. The state’s own monitoring data provides the exposure proof. The company’s own violation history provides the notice proof. The company’s own permit application — which said shutting down would cause “economic waste” — provides the conscious-disregard proof.
How long do I have to file a lawsuit for H2S exposure in Texas?
Texas imposes a two-year statute of limitations on personal injury claims. However, in toxic exposure cases, the discovery rule may toll — pause — the clock until you knew or reasonably should have known that your health problems were caused by the gas. In a community where the state did not tell residents that H2S levels outside their homes exceeded workplace safety standards, where school principals were never warned of dangerous readings on their playgrounds, and where the environmental agency publicly claimed the smell was harmless — the argument that you could not have known is strong. But statutes of repose and other deadlines can cut off claims even before discovery. The specific deadline for your family depends on your individual timeline. Do not wait to find out. Call a lawyer who can evaluate it.
What health problems can hydrogen sulfide cause in children?
Children are uniquely vulnerable to H2S exposure because their respiratory and neurological systems are still developing. Chronic low-level exposure — the kind that comes from living near leaking oil tanks and unlit flares for years — has been linked to headaches, nausea, eye and nose irritation, coughing, asthma, and rashes. An EPA toxicologist’s report identified fatigue, poor memory, personality changes, and hallucinations as effects of chronic low-level exposure. The full extent of neurological and respiratory damage may not declare itself for years, which is why medical monitoring — ongoing surveillance by a physician who knows what to look for — is a critical component of any claim involving a child exposed to H2S.
Who are the defendants in an H2S toxic tort case?
The defendant structure in these cases is multi-layered. The facility operator — such as Cambrian Management or its successor Octane Energy — is the primary defendant, responsible for the day-to-day leaks. The operator’s co-owner and management can be named individually where their personal decisions reflect conscious disregard. The midstream company — DCP Midstream, now part of Phillips 66 — whose decision to refuse the gas stream forced the flaring, is a deep-pocket defendant with a direct causal link to the pollution. If the exposure occurred at a different facility, the operator of that facility — such as Aghorn Operating, which faces federal criminal charges — is a separate defendant. In school-exposure cases, the school district may face claims for failing to protect students from a known environmental hazard. Identifying every responsible entity is the first step in building a case that can actually compensate your family.
What if the oil company says the smell is just a nuisance and not harmful?
That is a defense the company will use, and it is contradicted by the government’s own evidence. The state’s air analysts became physically ill — racing hearts, headaches, nausea — when they encountered the gas at the levels measured in the neighborhood. The EPA toxicologist cited in a federal criminal prosecution identified chronic low-level H2S exposure as causing neurological damage, respiratory problems, and increased ER visits. The Texas A&M professor who studies oil-field air pollution called the residential levels “shocking” and said nobody should be living near the facilities. The “it’s just a smell” argument is a position engineered to minimize enforcement, not a medical conclusion. A board-certified toxicologist testifying in your case will explain to a jury exactly what H2S does to the human body at the concentrations the state measured outside your home.
Can my children’s school be held responsible for H2S exposure?
Schools in the H2S footprint face potential claims for failing to protect students from known environmental hazards. At Murry Fly Elementary, a state monitoring station recorded 185 exceedances of the state H2S limit since 2020 — and the principal says he was never warned. At Noel Elementary, the H2S alarm system does not log the concentrations it detects, meaning nobody knows what levels the students were exposed to. A 2016 shelter-in-place event was triggered by the alarm. The school district has no records it was ever notified of elevated levels. When a school knows — or should know — that its students are breathing toxic gas and fails to act, that failure is a breach of the duty the school owes to the children in its care.
What is my H2S exposure case worth?
Case value depends on the number of family members affected, the severity and provability of injury, the duration and concentration of exposure, the defendant’s collectibility, and the venue. An individual family case — with four to six members exposed to H2S at levels exceeding state limits over multiple years, with children’s health impacts, property devaluation, and strong evidence of the operator’s conscious disregard — can range from approximately $2 million to $15 million. A community mass tort can aggregate to $50 million to $250 million or more. A wrongful death case — such as the Dean family, where two people were killed by acute H2S exposure — can range from $10 million to $40 million or more. The presence of a deep-pocket defendant like Phillips 66, the strength of the state’s own monitoring data, and the visually devastating infrared video evidence all amplify value. The small operator’s uncertain insurance depth, the contested causation landscape, and the oil-industry-dependent venue are deflators. Past results depend on the facts of each case and do not guarantee future outcomes.
Is it too late to file a claim if the exposure has been happening for years?
It may not be too late. The discovery rule in Texas can toll the statute of limitations in cases involving latent injury or disease — meaning the clock may not have started until you connected your health problems to the gas. In a community where the state itself withheld information about dangerous H2S levels from residents, where the environmental agency publicly claimed the smell was harmless, and where school officials were never notified of exceedances — the argument that residents could not have known of the cause of their symptoms is strong. But this is not a question to answer by reading a website. The specific deadline depends on your individual circumstances. Call a lawyer who can evaluate your timeline before you assume it is too late.
What should I do if the oil company’s representative texts me and offers to help?
Be careful. Every communication with the company is building its defense file. The text messages may feel helpful — the representative says he will “send someone back to the site” — but they are also documenting the company’s actual knowledge of ongoing leaks and resident complaints, which is evidence. Save every text. Do not sign anything the representative offers. Do not accept a check. Do not give a recorded statement. Do not agree to let the company inspect your property. The company’s representative is not your advocate. Contact a lawyer before responding to any offer, and let the lawyer handle communications from that point forward.

He knows how the other side values a file, how it selects IME doctors, how it runs surveillance, and how it uses delay tactics. Now he uses that knowledge for injured clients. Lupe is fluent in Spanish and conducts full consultations in Spanish without an interpreter. Lupe’s full background is here.
These cases are built on the company’s choices — the maintenance records that show what they knew, the permit applications that show what they valued, the violation history that shows what they ignored, and the internal communications that show what they said to each other when they thought no one was listening. We go find those things. The preservation letter goes out the day you call. The records demands follow. The experts are assembled — a toxicologist for causation, an industrial hygienist for exposure reconstruction, a pediatric pulmonologist for the children, a neurologist for the cognitive effects, a petroleum engineer for the industry-standard leak prevention that was not implemented, and a forensic economist and life-care planner for the medical monitoring cost projections.
We work on contingency. That means you pay nothing unless we win your case. The consultation is free. The call is confidential. And the phone is answered 24 hours a day, seven days a week, by live staff — not an answering service.
