Walk onto a working lease and count the logos. Count them on the hard hats, on the trucks, on the trailers, on the tanks, and on the equipment. Every one of those logos is a different company. The oil company that holds the lease is one. The company that brought the rig is another. The frac crew, the wireline crew, the trucking outfit, the tank rental company, the safety consultant, etc., they are all separate businesses. A lot of them may have never worked together before this one job, and they will scatter to the next lease the day it is over.
So when a worker goes down out there, the first major question is not necessarily “who do we sue.” It is “who actually caused this.” And out in the oil patch, the answer is almost never just one name.
This page breaks down in plain words how Texas law sorts out responsibility after an oilfield injury or death. It talks about who the players are, why more than one company is usually on the hook, how the law splits the blame between them, and why the company that is easiest to sue is not always the one that caused the harm. It is written for the worker who got hurt out there, and for the family of a worker who never made it home.
Here is the part the companies do not talk about publicly. The system is built so that the moment somebody gets hurt, every company on that site starts pointing fingers at the others, and every one of them would rather you chase the smallest company in the chain and call it a day. The job of a qualified oilfield injury lawyer is the opposite of that. It is to map the whole chain and find every company that made a dangerous choice, hold them responsible so they have to repay what you lost, and try to make them change their ways so they will not hurt anyone else in the future.
The short and plain version
- An oil and gas site is crowded. The operator, the drilling contractor, a dozen service companies, the company man, and a chain of subcontractors are all out there at the same time.
- When a worker gets hurt, usually more than one of those companies is responsible. The job is to find every one of them, not just the easy one.
- A "third party" claim is a claim against a company that is not your employer. Those claims are often where the real recovery is.
- Texas uses a system called "proportionate responsibility." That means a jury can put a share of the blame on each company, and even on you.
- Your own employer is a separate question. It usually turns on workers' comp, and that one is covered in its own guide.
- The company that is easiest to sue is not always the one that caused the harm. The right lawyer maps the whole chain before deciding anything.
A well site is crowded: the who’s who of the patch
Before you can figure out who is responsible, you have to know who is even out there. On a normal oil and gas site, you are looking at five, six, sometimes ten or more separate companies, all working at the same time, all under different bosses. Here is the cast.
The operator
The operator is the oil company at the top. It holds the lease, it makes the decisions, and it makes the money.
The "operator" is the oil and gas company that holds the lease and runs the project. It decides where the well goes and who gets hired to drill it. Most of the time, the operator does not put its own people on the dangerous parts of the job. It hires contractors for that. In a lot of cases the operator is also the "property owner" that gets the Chapter 95 shield, which is its own subject. See the Chapter 95 guide.
The drilling contractor
The operator usually does not own the rig or employ the crew that runs it. It hires a drilling contractor for that. The drilling contractor brings the rig, the tools, and the hands who actually turn to the right and drill the hole.
The service companies
This is the biggest group, and it is where most of the workers come from. Service companies are the specialists the operator brings in for one piece of the job: the frac company, the wireline company, the cementing company, the coil tubing company, the well-servicing or workover company, the tank rental company, the company that hauls the water and the sand and the crude.
A "contractor" or "service company" is a company the operator hires to do a specific job, like drilling, fracking, cementing, hauling, or servicing the well. Each one is a separate business, with its own crew, its own equipment, its own insurance, and its own safety rules (or lack of them). On a busy lease, there can be a dozen of these working at once.
The company man
Out on location, the operator usually has one representative watching over everything. The hands call him the “company man.” He is the operator’s eyes on the ground, and he often has authority over what happens and when.
The "company man" is the operator's representative on the well site, the person watching over the work for the oil company. Sometimes he is an actual employee of the operator. Sometimes he is a "consultant" hired through a separate staffing company. Who actually signs his paycheck can matter a lot, because it changes which company is on the hook for what he does or fails to do.
The subcontractors
It rarely stops at the operator and the contractor. The contractor hires subcontractors, and those subs sometimes hire their own subs. The chain can run three or four companies deep before you get to the hands tripping pipe.
A "subcontractor" is a company hired by another contractor, instead of directly by the operator. So the operator hires the contractor, the contractor hires the subcontractor, and the worker who gets hurt often works for the smallest company at the very bottom of that chain. That bottom spot is not an accident. It is usually where the cost and the blame are set up to land.
The equipment and trucking companies
Last, there are the companies you do not always see standing on the location, but whose work is everywhere on it. The company that built or sold a piece of equipment. The company that rented it out or was supposed to maintain it. And the trucking companies hauling rigs, water, sand, and crude up and down the lease roads, which is its own enormous source of danger, because crashes kill more oilfield workers than anything else.
When you put it all together, a single well site is not simply one company with one crew. It is pretty much a temporary city of separate businesses, each one doing its own piece, each one with its own duty to do that piece safely. And here is the thing most people do not realize until it is too late: the workers doing the most dangerous parts of the job are almost never employed by the company at the top.
The people getting killed out there work for contractors, not the oil company. Federal researchers at NIOSH (the worker-safety arm of the CDC) tracked 470 oil and gas extraction worker deaths from 2014 through 2019. About 60 percent of the workers killed were employed by well-servicing companies, about 18 percent by drilling contractors, and only about 5 percent by the operators themselves. In plain terms, the overwhelming majority of people who die in the oil patch work for contractors and subcontractors, not for the oil company that runs the lease.
CDC, Morbidity and Mortality Weekly Report, "Fatalities in Oil and Gas Extraction Database, United States, 2014 to 2019" (Surveillance Summaries, September 1, 2023)The important first question: who caused this
People think the first question after an injury is “which company do I sue.” It is not, it goes deeper than that. The first real question is who actually caused this to happen.
That sounds obvious, but it is where a lot of cases go wrong. The easiest company to point at, usually the worker’s own small employer, is often not the company that made the dangerous decision. The dangerous decision may have been made somewhere else. Maybe the operator pushed the job too fast. Maybe a service company sent out broken equipment. Maybe the company man told the crew to keep working in conditions that should have stopped the job. Maybe a trucking company put a driver on the road who had been awake for twenty hours.
In the law, “fault” is not just a feeling or hunch. To hold a company responsible, you generally have to show three things: that the company owed a duty to be careful, that it broke that duty, and that breaking it actually caused the harm. The reason oilfield cases get complicated is that on a crowded location, more than one company usually owed you a duty, and more than one usually broke it. Sorting that out is the whole ballgame folks, and it is the subject of the next two sections.
Why more than one company is usually responsible
Let’s start with a simple idea. Every company on that site owes its own duties. The drilling contractor has to run the rig safely. The frac company has to run its spread safely. The equipment company has to send out gear that works properly. The trucking company has to put rested, qualified, safe drivers on the road. When any one of them cuts a corner and a worker gets hurt, that company can be responsible, all on its own, no matter what the others did.
But the bigger fights, and often the bigger recoveries, are about reaching the companies that sit above the worker’s small employer. There are a few legal paths to do that, and they come up over and over in oilfield cases.
The company that controlled the work. As a general rule, a company that hires an independent contractor is not responsible for how the contractor does the work. There is an important exception to that though, and it is a big one. If the company up the chain kept or used the right to control how the work was done, the means, the methods, the details, etc., then it can owe a duty too. The Texas Supreme Court put it plainly in Dow Chemical Co. v. Bright: it is the contractual right to control the work, not just whether the company actually stepped in, that creates the duty, and that control has to relate to the actual thing that hurt you. So if the operator or an upper-tier contractor was running the show, telling the crew how and when and in what order to work, that company is in the picture. (This same idea of “control” is the doorway past Chapter 95, which the Chapter 95 guide covers in detail.)
A note from me. Before I started my firm, I spent years as in-house corporate counsel, first as Associate General Counsel for a technology company and then as General Counsel for a global publishing company. A big part of that job was drafting and negotiating service contracts and the control language inside them. Different industry, but the same contractual architecture. When a Texas court asks whether the operator "retained the right to control" the work, it is reading the exact kind of language I used to write and negotiate, which usually lives in the Master Service Agreement. I know what the drafters were trying to accomplish, and I know where that language tends to crack when a real person actually gets hurt. The contract that often decides this question is covered in the Master Service Agreements guide.
The company that took on safety, and did it badly. Sometimes a separate company steps in and takes over a safety job. It could be a third-party safety company, a consultant, the operator’s own safety people, or an outfit hired to inspect or train or watch the site. Texas law says that when a company voluntarily takes on a job like that, it has to do it with reasonable care. Lawyers call this a “negligent undertaking” claim, and Texas courts have built it on a rule from the Restatement (Second) of Torts, Section 324A. The Texas Supreme Court laid out how it works in Torrington Co. v. Stutzman. The plain version: if a company stepped up to handle safety and then handled it carelessly, and people were counting on it or were put at greater risk because of it, that company can be on the hook, even though it was not your employer.
The company that made or maintained the equipment. If a defective tool, a worn-out line, or a piece of equipment that was never properly maintained caused the injury, the company that built it, sold it, rented it, or was responsible for maintaining it can be a defendant. That is a separate claim against a separate company, with its own insurance behind it.
The trucking company. Because crashes are the number one killer in this industry, an oilfield case is often, underneath it all, a trucking case. The driver’s employer, the company that loaded or dispatched the truck, and sometimes the operator that pushed the schedule can all be in the picture.
All of these are different ways of getting to the same honest place: the company that actually caused the harm. And when the company that caused the harm is not your employer, the claim against it has a name.
A "third-party claim" is a claim against a company that is not your employer. Your employer is one question (that one usually runs through workers' comp). A "third party" is everybody else on that site: the operator, the other contractors, the service companies, the equipment companies, the trucking companies. In a lot of oilfield cases, the third-party claim is where most of the real recovery is, because it reaches the companies with the most insurance and often the most responsibility. Some lawyers see a workers' comp check and stop looking. That is a mistake, because it can leave the third-party claim, the bigger part of the case, sitting on the table.
The reason this matters so much is simple math. The workforce out there is overwhelmingly contractor labor, which means the chain of companies, and the chain of possible defendants, is usually long.
The oilfield workforce is mostly contractors, which means a long chain of companies. From 2018 through 2022, there were about 2.1 specialist (contractor) workers in the U.S. oil and gas extraction industry for every 1 worker employed directly by an operator. The center of gravity has moved heavily toward the contractor and subcontractor side, which is exactly why an oilfield injury usually involves several separate companies, not one.
U.S. Bureau of Labor Statistics, Monthly Labor Review, "Describing the U.S. oil and gas extraction workforce with public data" (2025)If you got hurt on an oil and gas site and you are not sure who was even responsible, that is normal, and it is not your job to figure out alone. I am available for a free conversation, no pressure and no obligation.
Call or text (210) 460-0569How the law splits the blame: proportionate responsibility
So you may have several companies that share the blame. How does Texas decide how much each one owes? Through a system called “proportionate responsibility.” It lives in Chapter 33 of the Texas Civil Practice and Remedies Code, and you can read the actual statute on the Texas Legislature’s website.
"Proportionate responsibility" is the Texas way of splitting up the blame. Instead of one company being responsible for everything, the jury looks at everyone involved and assigns each one a percentage of the fault. Those percentages have to add up to 100. The dollars then follow the percentages. It is the law's way of saying each company pays for its own share of the harm.
Here is how it actually works, in plain words.
The jury puts a percentage on everyone. At trial, the jury is handed a list of everyone who might share the blame, and it assigns each a percentage of responsibility. That includes each company. It can also include you, the injured worker, if the company argues you were partly at fault. All the percentages together add up to 100.
Your own share can reduce or even erase your recovery. This is the part to understand clearly. Under Section 33.001, if the jury decides you were more than 50 percent at fault, you recover nothing. That is often called the “51 percent bar.” If your share is 50 percent or less, you can still recover, but your recovery gets cut by your percentage. So if your damages are 100 and the jury puts 20 percent of the blame on you, you collect 80. This is exactly why one of the first things the companies will try to do is pile the blame onto the worker. Naming the move out loud: shifting fault onto you is not a side issue for them, it is the whole defense.
Usually each company pays only its own share. As a general rule, each company is responsible for its own percentage and no more. A company found 30 percent at fault pays 30 percent of the damages.
But a company found mostly at fault can be on the hook for all of it. There is an important exception in Section 33.013. If a single company is found more than 50 percent responsible, it can be made “jointly and severally” liable, which means it can be forced to pay the entire judgment, not just its slice, and then go fight the other companies for their shares itself. That matters a great deal when some of the companies cannot pay.
The empty chair: “responsible third parties.” Here is a defense move you should know about. Under Section 33.004, a company you sue is allowed to point at someone who is not in the lawsuit and ask the jury to put a share of the blame on them. Lawyers call this designating a “responsible third party,” or pointing at the “empty chair.” The company in the empty chair might be one that went out of business, one that cannot be sued, or one nobody named. The jury can still assign it a percentage, and every percentage parked in the empty chair is a percentage the companies you did sue do not have to pay. That is exactly why finding and pursuing every responsible company early matters so much. Blame that lands on an empty chair can vanish, and take part of your recovery with it.
A short, plain summary of how Texas courts and the Texas Legislature handle who is responsible. This is legal background, not a prediction about any specific case.
Proportionate responsibility (Tex. Civ. Prac. & Rem. Code ch. 33). Texas law has the jury assign a percentage of fault to each party, including the injured worker. A claimant more than 50 percent at fault recovers nothing. A defendant more than 50 percent at fault can be jointly and severally liable for the whole judgment. Defendants may also designate absent "responsible third parties" for the jury to consider.
Dow Chemical Co. v. Bright, 89 S.W.3d 602 (Tex. 2002). A company that hires an independent contractor generally is not liable for the work, unless it kept the right to control the means, methods, or details of that work, and the control relates to the injury (at 606). The right of control is the key to reaching the company up the chain.
Torrington Co. v. Stutzman, 46 S.W.3d 829 (Tex. 2000). A company that voluntarily takes on a safety-related task must use reasonable care. This "negligent undertaking" theory, drawn from Restatement (Second) of Torts Section 324A, can reach a company that took over safety even when it was not the worker's employer (at 834-36).
Painter v. Amerimex Drilling I, Ltd., 561 S.W.3d 125 (Tex. 2018). A company can be responsible for the acts of a worker who was acting in the "course and scope" of work for that company. That is called "vicarious liability," and it applies when an employee is performing regular or specifically assigned duties for the employer's benefit, including under the "special mission" exception to the coming-and-going rule (at 139). The related question of which company a worker truly answered to also drives the borrowed servant subject.
In re East Texas Medical Center Athens, 712 S.W.3d 88 (Tex. 2025). The most recent Texas Supreme Court decision in this area. It held that the proportionate-responsibility system applies even to a worker's negligence claim against a non-subscribing employer, and that the employer may designate absent "responsible third parties" for the jury to weigh. A reminder that the percentage-of-blame framework, and the empty chair, reach across Texas injury cases.
Your own employer is a separate question
Everything above is about the other companies, the third parties. Your own employer is its own separate question, with its own rules, and it usually runs through workers’ compensation.
The short version is this. If your employer carried workers’ compensation insurance (a “subscriber”), you usually cannot sue that employer directly, even if it was careless. Workers’ comp is what is called the “exclusive remedy” against a subscribing employer. But that bar only protects your employer. It does nothing to stop your third-party claims against all the other companies on the site. If your employer did not carry workers’ comp (a “non-subscriber,” which Texas uniquely allows), the rules change in a big way, and you may be able to sue the employer directly. That whole subject, subscriber versus non-subscriber, and why it changes everything, is covered in the workers’ comp and non-subscriber guide.
There is one more wrinkle worth naming here, because it sits right at the line between “your employer” and “a third party.” Sometimes a company that is not on your paycheck controls your work so completely that the law treats it as your employer anyway, for the limited purpose of the workers’ comp bar. Lawyers call this the “borrowed servant” doctrine, and it turns on that same right-of-control question from Section 3. Companies use it both ways: an operator may argue you were its “borrowed servant” to try to claim the workers’ comp shield, or the facts may cut the other direction and open a claim. It is a technical area, and it is covered in its own guide.
The reason this split matters is money and responsibility, both. The workers’ comp check, if there even is one, comes from your employer’s side. The real accountability, and often the real recovery, usually comes from the third-party side, the companies that actually controlled the work or sent out the danger. A case worked from only one side is a case worked halfway.
What this means for you and your family
Here is the plain version of everything above.
When a worker gets hurt on an oil and gas site, there is almost never just one company to blame. There is a whole chain of them. The oil company sits at the top. The contractors and service companies work in the middle. The small company that signed your paycheck is at the bottom. Trucking and equipment companies move through it all. More than one of them is usually at fault.
Texas law splits the blame by percentage. A jury can put a share of the blame on each company, and on you. If they decide you were more than half at fault, you get nothing. So do not be surprised when the companies try hard to pin it on you. That is the game, and now you know it is coming.
Your own employer is a separate question. That one usually runs through workers' comp. But the bigger part of your case is often the claim against the other companies, the "third parties." That is where the most blame and the most insurance money usually sit. A workers' comp check is not the whole story. Anyone who tells you it is has not finished the job.
So here is what it all comes down to. The lawyer you pick matters more here than in almost any other kind of injury case. You need someone who will not stop at the easy company. You need someone who maps the whole chain, finds every company that made a dangerous choice, and goes after the ones who caused the harm. The next section gives you the questions to find that person.
You do not have to sort out who is responsible on your own. That is the lawyer's job, not yours. If you are not sure where your case stands after an oilfield injury, call me. The conversation is free, and I will be straight with you about who might be responsible and whether you have a real claim, even if the answer is not what you were hoping to hear.
Call or text (210) 460-0569Questions to ask any lawyer you are considering
You do not have to take anyone’s word, including mine. Test any lawyer you talk to. These questions will tell you fast whether they know this kind of case.
- Ask them how they would find every company that shares the blame, not just your employer. A real answer names the operator, the contractors, the equipment companies, and the trucking companies.
- Ask them to explain a "third-party claim" and why it might matter more than your workers' comp claim.
- Ask whether the company up the chain "controlled the work," and how they would find that out, including what the Master Service Agreement says.
- Ask what "proportionate responsibility" means and what happens if the other side blames you.
- Ask what happens if one of the responsible companies has gone out of business or cannot pay.
- Ask about their experience with oilfield cases, and whether they work with experienced co-counsel or law firms on serious ones.
- Ask how their fee works, what expenses they cover up front, and what happens if the case does not win.
A lawyer who knows this work will welcome these questions. A lawyer who gets vague, weird, or defensive is telling you exactly what you need to know.
Common questions
Can I sue more than one company? +
Yes. In oilfield cases you often can, and often should. A busy well site has many separate companies on it, and more than one is usually to blame. Texas law is built for this. A jury can place a share of the blame on each company. The goal is to find every company that made a dangerous choice, not just the easy one.
What is a third-party claim? +
A third-party claim is a claim against a company that is not your employer. Your own employer is one question. It usually runs through workers' comp. A "third party" is everyone else on the site. That means the operator, the other contractors, the service companies, the equipment makers, and the trucking companies. In many oilfield cases, the third-party claim is the bigger part of the case. Those companies often carry the most insurance and hold the most blame.
Who is the "company man," and can he be responsible? +
The company man is the operator's representative on the site. He watches over the work for the oil company. Whether he and his company can be on the hook usually comes down to how much control he had over the job that hurt you. If he was telling the crew how and when to work, that points back at the company he works for. Sometimes that is the operator. Sometimes it is a separate staffing company. So it matters to find out who really employed him.
What if the company that hurt me has gone out of business? +
It can still matter, and it may not end your case. Often there is insurance that still pays even after a company closes. And since more than one company is usually to blame, there may be others still standing. Watch out for one thing. The other side can try to pin the blame on the company that is gone. That is one more reason to find everyone responsible early, before that blame slips away onto an empty chair.
How does a jury split the blame? +
The jury gives each side a share of the blame, written as a percentage. All the shares add up to 100. That can include the companies, and it can include you. As a rule, each company pays its own share. But a company found more than half to blame can be made to pay all of it. And if the jury finds that you were more than half to blame, you get nothing.
Is the operator always responsible? +
No. The operator sits at the top of the chain, but it is not automatically on the hook. As a rule, a company that hires an independent contractor is not responsible for how that contractor does the work. The operator becomes responsible when it kept or used the right to control how the work was done, or when its own choices caused the harm. Whether that is true depends on the facts, and often on the contract.
What if I was partly at fault? +
You may still have a case. Texas does not cut you off just because you made a mistake. If the jury finds you were half to blame or less, you can still recover. Your share just gets subtracted from what you collect. You only lose it all if you are found more than half to blame. Do not let the other side talk you out of a claim by making you feel like it was all your fault. Making you feel that way is part of their job.
