Most oilfield workers have more than a workers’ compensation claim. Whether they know it depends on who employed them, who owned the pad, and whether the employer opted out of comp entirely.
The Railroad Commission maps the Eagle Ford across 27 South Texas counties — Karnes, La Salle, Dimmit, Frio, McMullen, Live Oak, Atascosa, Wilson, Gonzales, DeWitt, Webb and others, most of them within two hours of Bexar County. That is our backyard, and it is where these cases are worked and often tried.
The federal fatality data is blunt about how oilfield workers die. NIOSH’s Fatalities in Oil and Gas Extraction database recorded 470 deaths between 2014 and 2019: vehicle incidents 26.8%, contact injuries 21.7%, and explosions 14.5%. The Western Gulf Basin, which includes the Eagle Ford, accounted for 15.7% of them. OSHA puts it more plainly still — roughly four of every ten workers killed on the job in this industry die in highway incidents, and three of every five on-site fatalities come from being struck by, caught in, or caught between equipment.
In Texas, 62 people died in mining, quarrying and oil and gas extraction in 2024, up 22% from the year before. Twenty-six of those were in support activities for oil and gas operations — the contractor tier, where most third-party claims live.
About a quarter of Texas private employers are non-subscribers — they carry no workers’ compensation insurance at all. Workers often assume this leaves them worse off. Under Texas law it frequently leaves them far better off.
Tex. Lab. Code § 406.033(a) strips a non-subscribing employer of the three defenses that normally decide a workplace injury case. In a suit by an employee, the employer may not assert:
— that the employee was guilty of contributory negligence;
— that the employee assumed the risk of injury or death;
— that the injury was caused by the negligence of a fellow employee.
Read that against Texas’s ordinary rule. In a normal negligence case, Chapter 33 bars recovery entirely if the plaintiff is more than 50 percent responsible, and reduces it by whatever percentage the jury assigns. Against a non-subscriber, that reduction does not happen. The employer gave it up when it opted out. What remains to the employer under § 406.033(c) is narrow: an injury caused by the employee’s own act intended to bring about the injury, or intoxication.
Section 406.033(e) also makes pre-injury waivers void and unenforceable. And a post-injury waiver is valid only if it is voluntary, knowing, in writing, conspicuous, signed after a medical evaluation, and no earlier than the tenth business day after the injury was first reported. If someone put a document in front of you in the first week, it is worth having a lawyer look at it.
Where the employer is a subscriber, Tex. Lab. Code § 408.001(a) makes comp benefits the exclusive remedy against that employer. There is one carve-out, and it is narrow: § 408.001(b) preserves exemplary damages for the surviving spouse or heirs of the body of an employee whose death was caused by the employer’s intentional act or gross negligence. Only in death cases, only for those beneficiaries, and only exemplary damages.
But the exclusive remedy bars claims against the employer. It says nothing about anyone else — and a working Eagle Ford pad is crowded. There is an operator, a drilling contractor, a wireline company, a pressure-pumping company, a trucking company, a rental-tool supplier, and a well-site supervisor company, each a potential third-party defendant to the others’ employees. That is where most of the value in an oilfield case sits.
Expect two defenses. First, borrowed servant arguments trying to extend the comp bar to a company that was not your employer on paper. Second, Chapter 95 of the Civil Practice and Remedies Code, which limits a property owner’s liability to an independent contractor’s employee unless the owner retained control and had actual knowledge of the danger.
Nearly every relationship on an Eagle Ford pad is governed by a master service agreement, and the MSA — not the caption of the lawsuit — usually determines which insurance tower funds the case.
The Texas Oilfield Anti-Indemnity Act, Chapter 127 of the Civil Practice and Remedies Code, voids an agreement that purports to indemnify a party against liability for its own negligence in a contract pertaining to a well (§ 127.003). But § 127.005 creates an exception that swallows much of the rule: the chapter does not apply where the parties agree in writing that the indemnity will be supported by liability insurance. For mutual obligations, the indemnity is capped at the coverage each side agreed to carry; for unilateral obligations, the required insurance may not exceed $500,000.
The practical consequence is that virtually every South Texas MSA is a knock-for-knock mutual indemnity backed by insurance, engineered to fit § 127.005(b). Getting the MSA and its insurance schedules early is not housekeeping — it is how you learn what the case is actually worth.
H₂S is endemic to parts of the Eagle Ford, and its physiology is why sour-gas cases turn out the way they do. The odor threshold is between 0.01 and 1.5 ppm — you can smell it long before it can hurt you. But at roughly 100 ppm, the sense of smell is lost within two to fifteen minutes. The warning disappears precisely when the danger begins.
At 500 to 700 ppm a worker staggers and collapses within about five minutes. At 700 to 1,000 ppm, unconsciousness follows within one or two breaths. Above that, death is nearly immediate.
The exposure limits matter in litigation because they define the duty. OSHA’s general industry standard, 29 C.F.R. § 1910.1000 Table Z-2, sets a 20 ppm ceiling with a 50 ppm peak permitted for a single period of up to ten minutes if there is no other measurable exposure that shift. The construction standard, § 1926.55, is a 10 ppm time-weighted average. NIOSH’s recommended limit is 10 ppm as a ten-minute ceiling, and the IDLH value is 100 ppm.
The related cluster is manual tank gauging and flowback. OSHA and NIOSH issued a joint hazard alert (OSHA 3843) after a run of deaths at open thief hatches — hydrocarbon vapor overexposure and oxygen displacement, sometimes with ignition. If a worker was found down at a tank hatch, that alert and the employer’s response to it belong in the file.
Under 29 C.F.R. § 1904.39, an employer must report a work-related fatality to OSHA within eight hours, and an in-patient hospitalization, amputation, or loss of an eye within twenty-four hours.
Those reports, and the OSHA inspection file and any citations that follow, are early, independent, and frequently obtainable before suit is filed. They are also created by the employer at a moment when no one has yet retained a lawyer, which is often when the account is most candid.
Subscriber or non-subscriber changes the entire structure of the case. So does whether you were a direct employee, a contractor’s employee, or a leased worker.
The master service agreement, its insurance schedules, and the daily reports. These identify every company on the pad and which carrier will fund the case.
Equipment, gas monitor logs, JSAs, permits, training files, and the employer’s § 1904.39 report — before the site is cleaned and the equipment returned to a rental yard.
Burn injuries, traumatic brain injury, amputation and inhalation injury all require specialized medical and life-care proof. In a death case, the wrongful death and survival claims are proved separately.
Only if your employer actually carries workers’ compensation. Roughly a quarter of Texas private employers are non-subscribers, and against a non-subscriber you can sue directly in negligence — with the employer barred from arguing contributory negligence, assumption of the risk, or fellow-employee negligence under Tex. Lab. Code § 406.033. Even where the employer is a subscriber, the exclusive remedy only protects the employer. It does not protect the operator, the drilling contractor, the wireline or pressure-pumping company, the trucking company, or the equipment supplier.
Usually it helps, because it opens third-party claims that the workers’ compensation bar does not reach. It also brings Chapter 95 of the Civil Practice and Remedies Code into play, which limits a property owner’s liability to an independent contractor’s employee unless the owner retained control over the work and had actual knowledge of the danger. Whether that limitation applies is fact-intensive and turns on documents — the MSA, the daily reports, the safety program, and who was actually directing the job.
Only if you were working on a vessel. Drillships, semi-submersibles, liftboats, jack-ups under tow and crew boats can make a worker a seaman under Chandris v. Latsis, which requires a connection to a vessel in navigation substantial in both duration and nature. A fixed production platform is not a vessel — those injuries fall under the Longshore and Harbor Workers’ Compensation Act through OCSLA, with Texas law applying as surrogate federal law. Land-based Eagle Ford work is neither; it is a Texas case.
Two years from the injury for a Texas personal injury claim, and two years from the date of death in a wrongful death case. Maritime claims run three years. But the practical deadline is much shorter: equipment gets returned to rental yards, sites get cleaned, gas monitor data gets overwritten, and crews move on to the next job in another county. The investigation should start in days, not months.
Before you sign anything an employer hands you, find out whether they carried workers’ compensation at all. It changes everything about your claim.
