The operator usually has the deepest pockets on location and the biggest insurance policy. It also has one of the strongest legal shields in Texas. Here's how that shield works, where it stops, and what it takes to get past it.

What Is Chapter 95?

Chapter 95 is a Texas statute that limits a property owner's liability when a contractor or a contractor's employee is hurt while building, repairing, renovating or modifying an improvement on that property. It covers negligence claims of every kind, including claims that the owner failed to provide a safe workplace.

In the oilfield, the "property owner" is usually the operator that owns or leases the well site, and the "improvement" is the well, the pad and the equipment on it. The Texas Supreme Court has applied Chapter 95 squarely to well sites, including in Endeavor Energy Resources v. Cuevas (2019), where a drilling contractor's worker was killed on the operator's lease, and Energen Resources v. Wallace (2022).

The Two Things You Have to Prove

Under Civil Practice and Remedies Code 95.003, the operator is not liable unless both of these are true. Missing either one ends the claim against the operator.

1. The operator controlled how the work was done

The operator must have exercised or retained some control over the manner in which the work was performed. The statute spells out what doesn't count: the right to order work to start or stop, the right to inspect progress and the right to receive reports. Control means the operator told the crew how to do the job, not just when to start or stop.

Control can come from what the operator did on location or from what it wrote into the contract. A master service agreement or drilling contract that gives the operator the right to direct the method of the work can satisfy this part even if nobody exercised it that day.

2. The operator knew about the danger and didn't warn

The operator must have had actual knowledge of the danger or condition that caused the injury and failed to adequately warn. "Should have known" isn't enough. In Cuevas, the court made clear that knowledge is measured against the specific risk that actually hurt the worker.

What Control Looks Like on a Location

Operators always say the contractor ran the job. The paper trail often says something different. These are the facts that tend to prove control:

Why the drilling contract type matters

How the rig is paid often tracks who's in charge. On a daywork contract, the operator pays by the day and typically directs the operation through its company man. On a turnkey or footage contract, the drilling contractor usually runs the job and carries more of the risk. A daywork job is often where operator control is easiest to prove.

How We Prove Actual Knowledge

Actual knowledge is proven with the operator's own records and people. The documents that matter most:

Most of this lives on the operator's systems and on a rig that will move to the next location within days. A preservation letter sent early is often the difference between proving knowledge and guessing at it.

When Chapter 95 Doesn't Apply

The shield is strong, but it's narrow. It may not protect the operator when:

These lines are fought hard and decided case by case. In Energen, workers argued the danger came from a nearby oil well, not the water well they were drilling, and the Texas Supreme Court still applied Chapter 95. Don't assume you're outside it without reading the facts closely.

Watch for the operator that's also your employer

Some operators buy comp coverage for every contractor on the job through a wrap up program. Under Texas Labor Code 406.123, that can make the operator your statutory employer and protect it from suit entirely. Check the comp policy before you build a case against the operator. See when you can sue your employer.

If the Operator Is Out, Who's Left?

Plenty. Chapter 95 protects one company. The drilling contractor, service companies, crane outfits, frac crews and haulers on location are all judged by ordinary negligence rules, and equipment makers face product liability claims. The best oilfield cases look at every company on the pad, not just the name on the lease. See third party claims and comp liens and oilfield equipment failure claims.
