Drive south out of San Antonio on Highway 16 or Highway 281 and you’ll pass through it without a sign telling you so. The Eagle Ford doesn’t announce itself. It shows up in the truck traffic, the flare stacks burning at night, the new motels in towns that didn’t used to need them, and in the data, if you know where to look.
This is the part of Texas that pays for a lot of the country’s oil. It runs under counties most people only see through a windshield on the way to the coast: Karnes, DeWitt, La Salle, Dimmit, Webb, and a dozen more. The boom brought real money and real jobs to small towns out here. It also brought funerals.
This page goes county by county. It uses public records on drilling, on worker deaths, and on road crashes, so you can see where the danger sits and why. It’s not about any one accident, and it can’t tell you what your case is worth. What it can do is show you the pattern, in the government’s own numbers, and explain why where you got hurt is part of your story, not just a detail.
The short and plain version
- The Eagle Ford Shale runs across South Texas, through counties most people just drive past: Karnes, DeWitt, La Salle, Dimmit, Gonzales, Webb, and more.
- The boom brought jobs and money to small towns like Cotulla, Cuero, Three Rivers, and Pleasanton. It also brought death, destruction, and funerals.
- This page goes county by county, using public data on drilling, injuries, and road crashes, so you can see where the danger is concentrated.
- The lease roads are part of the danger. Oilfield truck traffic turned quiet two-lane highways into some of the deadliest roads in Texas.
- Oil and gas work is roughly four times deadlier than the average Texas job, and the number one way these workers are killed is on the road.
- Where you were hurt can affect your case, including which county's court hears it.
- The jobs are worth having. The funerals are not worth accepting.
What the Eagle Ford is, and the towns it changed
The Eagle Ford is a “shale play,” and that phrase is worth slowing down on, because the whole region runs on it.
A "shale play" is a large underground rock formation that holds oil and natural gas, plus the whole business of drilling it. The oil and gas are locked inside dense shale rock, so companies drill down and then sideways through the layer and use "hydraulic fracturing" (fracking), pumping water, sand, and chemicals at high pressure to crack the rock and let the oil and gas flow out. "The play" is shorthand for the formation and all the work happening on top of it.
The Eagle Ford formation runs across South Texas in a long band, roughly 50 miles wide and 400 miles long, sitting somewhere between 4,000 and 12,000 feet down. The Railroad Commission of Texas, the state agency that regulates oil and gas, lists 26 affected counties. It’s one of the biggest oil-producing regions in the country.
The Eagle Ford is named after the rock layer it produces from. When people say someone "works in the Eagle Ford," they mean the oilfield jobs across South Texas: drilling, fracking, well servicing, hauling sand and water and crude, building and running the pipelines and tank batteries. It's a job, a region, and a way of life all at once.
The scale shows up in the government’s own numbers. In 2025, the Eagle Ford produced about 1.2 million barrels of crude oil a day, which the U.S. Energy Information Administration counted as 9 percent of all the crude oil produced in the entire United States. Only the Permian Basin in West Texas produces more. Roughly 18 percent of all the oil pumped in Texas comes out of the Eagle Ford formation, by the Railroad Commission’s own production records. The Federal Reserve Bank of Dallas counts close to 399,000 jobs in the Eagle Ford counties.
That money is real, and the people earning it are real. So is the cost. The boom filled up the motels in Kenedy and Cotulla, put new trucks on the road in Cuero and Pleasanton, and brought paychecks to towns that had been losing young people for a generation. It also filled cemeteries. The same boom that pays the bills out here is the one that puts a family in a funeral home, and both of those things are true at the same time.
How to read this page: the data and where it comes from
Most law firm websites tell you the oilfield is dangerous and stop there. This page shows you the receipts, county by county, from the agencies that actually count.
Six public sources do most of the work here:
- The Railroad Commission of Texas (RRC) tracks drilling permits and oil and gas production.
- The U.S. Energy Information Administration (EIA) tracks how much the region produces.
- The U.S. Bureau of Labor Statistics (BLS) counts workers who are killed on the job.
- The National Institute for Occupational Safety and Health (NIOSH), part of the CDC, studies how and why oilfield workers die.
- The Texas Department of Transportation (TxDOT) records every reported crash in the state.
- The U.S. Census Bureau measures who lives in each county, and what they earn.
The data has limits, and you should know them up front. Government numbers run a year or two behind. Some of these counties are so small that a single bad year can swing the percentages. And the state does not publish a clean, county-by-county table of oilfield injuries, so for production rankings I lean on the Federal Reserve Bank of Dallas, which compiles the county figures from RRC and EIA data, and for crashes and population I use the TxDOT and Census county tables directly.
There’s one more thing the count misses, and it matters out here. A lot of the workforce doesn’t live in these counties at all. They drive in from Houston, the Valley, or across the border, work a hitch, and sleep in a “man-camp” (temporary worker housing, often RVs or modular units thrown up near the drilling). The Census counts permanent residents, so it undercounts the people actually on these roads and lease sites every day. Keep that in mind when a county’s population looks small. The danger doesn’t care whether you’re counted.
The core counties, one by one
Start with the compilation. The table below pulls together what each core county is, how many people the Census counts there, what a typical household earns, and what the roads did to people in a single recent year. Everything in it is from a government source, and the back matter lists each one.
| County | County seat | Population (2025 est.) | Median household income | Traffic deaths, 2024 | Fatal crashes involving a commercial truck, 2024 |
|---|---|---|---|---|---|
| Karnes | Karnes City | 15,018 | $60,214 | 8 | 2 |
| DeWitt | Cuero | 20,309 | $63,730 | 2 | 0 |
| La Salle | Cotulla | 6,517 | $57,716 | 7 | 1 |
| Dimmit | Carrizo Springs | 8,024 | $38,808 | 16 | 3 |
| Gonzales | Gonzales | 20,159 | $58,672 | 7 | 2 |
| Atascosa | Jourdanton | 53,590 | $70,770 | 9 | 3 |

| Webb | Laredo | 281,224 | $63,058 | 23 | 1 |
Population: U.S. Census Bureau QuickFacts (2025 estimate). Income: American Community Survey 2020–2024. Crashes: TxDOT 2024 crash records. "Commercial truck" follows TxDOT's commercial-motor-vehicle category.
A second table tells you where the oil and gas actually come from. The Federal Reserve Bank of Dallas, using EIA and RRC data, ranked the top producers at the end of 2024.
| Product | Number one | Number two | Number three |
|---|---|---|---|
| Crude oil | Karnes | DeWitt | La Salle |
| Natural gas | Webb | La Salle | Karnes |
Karnes, DeWitt, and La Salle together produced about 46 percent of the Eagle Ford's oil. Webb is by far the region's biggest gas producer. Source: Federal Reserve Bank of Dallas, "Energy in the Eleventh District: Eagle Ford Shale," 2024 figures.
Now the counties themselves.
Karnes County
Karnes is the heart of Eagle Ford oil. Around Karnes City and Kenedy, this one county pumps more crude than any other in the play, and together with DeWitt and La Salle it accounts for nearly half of all the Eagle Ford’s oil. But the Census counts only about 15,000 people in Karnes County, and that number has barely moved since 2010. That’s what a boom really looks like up close. The money came through, but most of the workers didn’t stay, so the boom shows up as truck traffic and production instead of families putting down roots. In 2024, eight people died on Karnes County roads.
DeWitt County
DeWitt, around Cuero and Yorktown, is the number two oil county and one of the steadier ones, with about 20,000 residents and a median household income just over $63,000. Its 2024 road numbers were the quietest in this group, with two traffic deaths and no fatal truck crashes. That’s a single year, and a single year can flip. It does not mean DeWitt is safe so much as it means the danger moves around the basin from year to year.
La Salle County
La Salle, with Cotulla sitting right on Interstate 35, is the number three oil county and the number two for gas. It’s small and getting smaller, around 6,500 people, with a poverty rate near 27 percent. The roads tell the story plainly. In 2024 the whole county had only 84 reported crashes, but three of them were fatal and killed seven people, and about half of all its crashes involved a commercial truck. When you mix interstate freight with loaded lease trucks on the same stretch, a low crash count can still carry a high body count.
Webb County
Webb is the gas heart of the Eagle Ford and a different animal from the rest. Laredo makes it the biggest county in the play by far, with about 281,000 people, and it’s one of the busiest freight corridors in North America, where I-35, US-59, and US-83 all funnel border trade. It produces more natural gas than anywhere else in the Eagle Ford. Its crash totals are huge, more than 6,700 in 2024, but those blend oilfield trucks with border freight and city traffic, so read Webb carefully. The oilfield is one current in a much bigger river here.
Dimmit County
Dimmit, around Carrizo Springs, is hard frac country, and it carries the marks of it. It has the lowest median household income of any county in this group, under $39,000, and a poverty rate near 28 percent. In 2024 it had eight fatal crashes, but those crashes killed 16 people. That gap is what high-speed, two-lane roads do: when a wreck happens out here, more than one person tends to die in it.
Gonzales County
Gonzales sits on the eastern edge of the play, around the towns of Gonzales and Nixon, with about 20,000 residents. It saw seven traffic deaths in 2024 across 480 crashes, more than 100 of which involved a commercial truck. It’s a reminder that the Eagle Ford reaches well east of the counties people usually name.
Atascosa County
Atascosa, around Pleasanton and Jourdanton, is the gateway south from San Antonio, where US-281 and I-37 carry the traffic into the field. It’s the second-largest of the inner-ring counties, near 54,000 people and growing as San Antonio spreads south. In 2024 it logged more than 900 crashes and nine traffic deaths, three of those fatal wrecks involving a commercial truck.
Live Oak County
Live Oak is the junction county. Around Three Rivers and George West, I-37, US-59, and US-281 come together, which puts a lot of oilfield iron through a county of only about 12,000 people. It had eight traffic deaths in 2024 across 435 crashes. If you’ve hauled in the southern Eagle Ford, you’ve driven Live Oak, probably tired, probably at night.
Frio County
Frio, around Pearsall on I-35, posted the most lopsided truck number in the whole group in 2024. Of its eight road deaths, seven came out of crashes that involved a commercial truck, and six of its seven fatal crashes were truck-involved. That’s about as clear a fingerprint of heavy industrial traffic as the crash data ever leaves.
Wilson County
Wilson, around Floresville and La Vernia, is the county where the oilfield meets the San Antonio suburbs. It has the highest income and the most college graduates in this group, and it’s the fastest-growing, which makes it more of a bedroom community than a pure oil patch. It’s on the list because the eastern Eagle Ford doesn’t stop at the county line, and a lot of workers who live a normal suburban life still drive into the field every morning.
McMullen County
McMullen is the purest picture of what an oilfield county looks like with everything else stripped away. Around Tilden, it’s one of the least-populated counties in all of Texas, about 544 people. There’s almost no town and almost nothing but lease road. In 2024 it had only two fatal crashes, and both of them involved a commercial truck, and trucks were in more than half of every crash the county recorded. When a place is nothing but pads, pipe, and the roads between them, the road is the whole risk.
The roads: oilfield trucking and the crash data
If you remember one thing from this page, make it this. The most dangerous piece of equipment in the Eagle Ford is the truck, and it isn’t close.
The federal researchers at NIOSH studied oil and gas worker deaths across the country and found that the single leading cause of death isn’t a blowout or a fall or a fire. It’s vehicle crashes, and most of those happen out on the public highway. A single fracked well can take hundreds of loaded truck trips, by some estimates more than a thousand, hauling the water, sand, pipe, chemicals, and crude in and out. Multiply that across thousands of wells and you get what South Texans already know: the two-lane roads out here carry a river of heavy iron they were never built for.
The Eagle Ford's roads got measurably deadlier when the boom hit. The Texas A&M Transportation Institute compared crashes before and during the boom. In the Eagle Ford, rural crashes involving commercial vehicles rose 61 percent from 2006–2009 to 2010–2013, even as total crashes across the rest of Texas fell about 7 percent. Counting quality-of-life losses the way the federal Department of Transportation recommends, the institute put the added cost of those industry-linked crashes at roughly $2 billion in the Eagle Ford alone, and estimated energy-boom damage to Texas roads at nearly $2 billion a year.
Texas A&M Transportation Institute, "Oil and Gas Energy Developments and Changes in Crash Trends in Texas," 2015The corridors carrying most of it are easy to name. Interstate 37 is the spine, running San Antonio to Corpus Christi through Atascosa and Live Oak. US-281 and US-59 feed in from the north and east. US-90, SH-72, SH-97, SH-16, and SH-44 thread the field. And under all of those sit the FM and county roads, built decades ago for a farm truck and a cattle trailer, now carrying 80,000-pound rigs day and night.
Two things stack on top of the traffic and make it worse, and both of them trace back to choices a company made.
The first is fatigue. Oilfield hands work long hitches, often 12-hour shifts, sometimes for many days straight, and then climb into a truck or a crew van for a long drive back to a man-camp or a motel. When a company schedules a worker for a 14th straight long shift and a 90-minute drive afterward, the exhaustion behind the wheel isn’t bad luck. It’s the predictable result of how the work was set up.
The second is the undercount, and it cuts in the worker’s favor to understand it. Highway crashes are not required to be reported to OSHA, the federal workplace safety agency. So OSHA’s own numbers miss most oilfield road deaths. When NIOSH cross-checked Texas crash records for just three years, it found 56 oil-and-gas motor-vehicle deaths that never showed up in the OSHA data at all, and in more than half of them the worker wasn’t wearing a seat belt. The official count of how many oilfield workers die on the road is almost certainly low, and the true number is worse.
Texas has not had a single day without a traffic death since November 7, 2000, a streak TxDOT marks with its #EndTheStreakTX campaign. In 2024, 4,150 people died on Texas roads, and just over half of those deaths happened in rural areas, where most Eagle Ford driving is.
TxDOT, "Texas Motor Vehicle Traffic Crash Facts," Calendar Year 2024; TxDOT #EndTheStreakTXThis is where the community-safety part stops being abstract. The loaded sand hauler doing 70 on a county road shares that road with the rancher’s wife, the school bus, and the family driving home from Sunday dinner. When a carrier skips maintenance, or pushes a driver past safe hours, or puts a barely-trained driver in a fully-loaded truck to keep up with the boom, the people they put at risk aren’t only their own workers. It’s everybody else on that two-lane road too.
If you or someone in your family was hurt or killed in an oilfield crash in the Eagle Ford, you can talk it through with me before you decide anything. The call is free, there's no pressure, and there's no obligation.
Call or text (210) 460-0569The pattern across the basin
Step back from the individual counties and three things come through clearly in the data.
First, this work is far deadlier than ordinary work. The Bureau of Labor Statistics measures a fatal-injury rate for each industry. For 2024, the rate for mining, quarrying, and oil and gas extraction was 13.8 deaths for every 100,000 full-time workers. For all American workers combined, it was 3.3. Doing this work is roughly four times more likely to get you killed than the average job in the country.
Second, the Eagle Ford sits inside one of the deadliest oil regions in the United States. When NIOSH studied oil and gas deaths nationwide from 2014 to 2019, the Western Gulf Basin, which includes the Eagle Ford, accounted for nearly 16 percent of all the deaths it counted, second only to the Permian Basin in West Texas. South Texas ranks among the deadliest oil regions in the whole country.
Third, the people doing the most dangerous work usually don’t work for the oil company whose name is on the gate. They work for the contractors and service companies the operator hires, and hires below that. That fact matters a great deal to who can be held responsible, and it has its own guide, but keep it in your head as you read these numbers. The worker is at the bottom of the chain. The operator is at the top. The risk gets pushed down, and the paycheck gets pushed up.
Texas leads the nation in workplace deaths. In 2024, 557 Texas workers were killed on the job, and the single leading cause was transportation incidents, with 242 deaths. Within the state's mining and oil-and-gas sector, transportation was again the top killer.
U.S. Bureau of Labor Statistics, Census of Fatal Occupational Injuries, Texas, 2024There’s a legal piece to “where,” and it’s worth a plain word here even though the depth lives on the legal spokes. Where you were hurt is not just a fact about geography. It can decide which courthouse hears your case.
"Venue" is the legal word for which county's court hears your lawsuit. It's a separate question from whether you have a case at all. Under the Texas general venue rule (Civil Practice and Remedies Code Section 15.002), a personal-injury suit can usually be filed in the county where a substantial part of what happened to you took place, which in an oilfield injury is normally the county where you got hurt. It can also often be filed where the company lives or keeps its main Texas office. When more than one county would work, the injured person usually makes the first choice, though the other side can challenge it and the venue facts have to be proven.
So a worker hurt on a lease in Dimmit County will often have his case heard in a Dimmit County district court, in front of a local judge and a jury drawn from the people who live out there. That can cut more than one way, and a qualified lawyer thinks about it early. It’s one reason the county on the accident report is never just a line on a form.
This is legal background, not advice about any specific case.
- Texas's general venue statute, Civil Practice and Remedies Code Section 15.002, generally allows a suit in the county where "all or a substantial part of the events or omissions giving rise to the claim occurred," among other options. In an oilfield injury, that's typically the county where the worker was hurt.
- The injured worker generally makes the initial venue choice among counties of proper venue (Wilson v. Texas Parks & Wildlife Department, 886 S.W.2d 259 (Tex. 1994)). That choice is subject to a timely venue challenge and the worker's burden to prove the venue facts (Alcus Reshod Fortenberry v. Great Divide Insurance Co., 664 S.W.3d 807 (Tex. 2023)).
- If a mandatory venue statute applies, it controls instead (Fortenberry, 664 S.W.3d 807). Chapter 95 and the question of who can be held responsible are covered in the legal guides linked below.
Here's the plain version of everything above.
The numbers on this page aren't about your accident. Your case is its own thing, with its own facts, and no chart decides it. What the data does show is that the danger out here is real and it's not evenly spread. The roads are the biggest killer. The work is about four times deadlier than a normal job. And the people getting hurt are usually working for a contractor, not the oil company whose name is on the sign.
Where you were hurt matters, and not only because it's where it happened. It can affect which county's court hears your case, and that can change how things go.
One worry I hear a lot: "I got hurt way out in the county, do I have to use some lawyer from out there?" No. You don't. A San Antonio injury lawyer can handle a case from Karnes, Dimmit, La Salle, or any Eagle Ford county. You get to choose who represents you, and you can choose someone who knows this work.
If you're in the middle of it right now, the most useful things you can do are simple: get the right medical care and make sure it's written down, keep every record, and find out whether your employer carries workers' comp or not. The first-30-days guide walks through exactly that.
Questions to ask any lawyer you are considering
You don’t have to take anybody’s word, including mine. The right questions will tell you fast whether a lawyer actually knows this kind of case or just runs ads.
- Ask whether they've handled oilfield cases in South Texas, and how they work them.
- Ask whether the county you were hurt in changes anything about your case, and why.
- Ask who else besides your employer might be responsible, and how they'd find out.
- Ask how they investigate an oilfield crash: the truck, the carrier, the driver's hours, the company that scheduled the work.
- Ask whether they bring in experienced co-counsel on big oilfield cases when it helps the client.
- Ask how the fee works, what expenses they cover up front, and what happens if the case doesn't recover.
A lawyer who does this work won’t be bothered by any of these. If the answers get vague or defensive, that tells you something.
You don't have to figure this out alone, and you don't have to decide anything today. If you're not sure where your case stands after an Eagle Ford injury, call me and I'll be straight with you about it, including whether the news is good or bad. The conversation is free and confidential.
Call or text (210) 460-0569Common questions
What counties are in the Eagle Ford Shale? +
The Railroad Commission of Texas lists 26 affected counties across South Texas. The core oilfield counties most people mean include Karnes, DeWitt, La Salle, Dimmit, Gonzales, Atascosa, Live Oak, McMullen, Frio, Wilson, and Webb. The play runs in a long band from the Mexican border up toward East Texas, roughly 50 miles wide and 400 miles long.
Does it matter which county I was hurt in? +
Yes, in a couple of ways. Where you were hurt is usually where your case can be filed, which decides the courthouse and the jury pool. It also shapes the practical side, like which records to pull and which companies were working that area. It does not decide whether you have a case. That depends on the facts and who was at fault.
Why are the roads in the Eagle Ford so dangerous? +
Because the boom put enormous truck traffic onto rural two-lane roads that were never built for it, and added tired drivers on long hitches to the mix. A single fracked well can take hundreds of loaded truck trips to drill and complete. The Texas A&M Transportation Institute found rural commercial-vehicle crashes in the Eagle Ford rose 61 percent during the boom, and federal researchers found vehicle crashes are the number one cause of death for oil and gas workers.
Which Eagle Ford counties have the most oilfield activity? +
For crude oil, Karnes leads, followed by DeWitt and La Salle. Those three alone produce close to half of the Eagle Ford's oil. For natural gas, Webb County around Laredo is by far the largest producer. That ranking comes from the Federal Reserve Bank of Dallas, using state and federal production data for late 2024.
Can a San Antonio lawyer handle a case from a rural county? +
Yes. You are not required to hire a lawyer from the county where you were hurt. A San Antonio injury lawyer can represent you in a case out of Karnes, Dimmit, La Salle, Webb, or any other Eagle Ford county. What matters is whether the lawyer understands oilfield work, not which town the office is in.
Where will my case be heard? +
Usually in the county where you were hurt, because Texas's general venue rule lets a suit be filed where a substantial part of the events happened. It can sometimes be filed where the company is based instead. When more than one county is proper, the injured person usually makes the first choice, though the other side can challenge it and you'd have to show the county is the right one. Some claims fall under special venue rules, so this is something to confirm with a lawyer early.
Is my immigration status a problem if I want to bring a claim? +
Immigration status does not automatically bar a Texas personal-injury claim, but it can affect case strategy and damages issues in some situations, so it's something to discuss with a lawyer directly. If this is a worry for you or your family, bring it up early so you get advice tailored to your situation.
How long do I have to do something about it? +
Many Texas personal-injury claims have a two-year deadline, but deadlines and exceptions can vary depending on the facts and who's involved, and key evidence like truck records and driver logs can disappear fast. If you think a deadline might be close, talk to a lawyer right away rather than guessing.
