Short answer
No. Chapter 127 of the Texas Civil Practice and Remedies Code does not require mutual indemnity or mutual insurance. It voids oilfield indemnity for the other party’s negligence unless the parties agree in writing that the indemnity will be supported by liability insurance. A mutual obligation is then enforceable to the extent of the coverage each side agreed to carry, while the insurance required to support a one-way (unilateral) obligation may not exceed $500,000.
- "Mutual" here describes the indemnity, not a type of insurance company. You can meet a mutual indemnity obligation with ordinary liability policies or qualified self-insurance.
What Chapter 127 actually does
Chapter 127 is usually called the Texas Oilfield Anti-Indemnity Act. It applies to an "agreement pertaining to a well for oil, gas, or water or to a mine for a mineral," which includes MSAs for well services, equipment rental, and incidental transportation. Joint operating agreements are excluded.
The core rule is in Section 127.003. A promise in one of these agreements is void if it tries to indemnify someone against loss caused by their own "sole or concurrent negligence" when the loss comes from personal injury, death, or property injury. In plain terms: absent an exception, an operator cannot make a contractor pay for the operator's own negligence.
The exception that matters most is insurance. Section 127.005(a) says the chapter does not apply if "the parties agree in writing that the indemnity obligation will be supported by liability insurance coverage to be furnished by the indemnitor," subject to the limits in subsections (b) and (c). Our Texas oilfield anti-indemnity act page covers the full statute.
Chapter 127: how insurance caps indemnity
Mutual versus unilateral: the two paths in Section 127.005
The statute defines two kinds of indemnity and treats them differently.
| Mutual indemnity obligation | Unilateral indemnity obligation | |
|---|---|---|
| Definition (Sec. 127.001) | Each party indemnifies the other (and the other’s contractors) for injury, death, and property damage to its own people and invitees | One party indemnifies the other for injury or death to its own employees or its contractors’ employees, with no reciprocal promise |
| Insurance limit on the obligation | Limited to the coverage and dollar limits of insurance or qualified self-insurance each party agreed to obtain for the other (Sec. 127.005(b)) | The amount of insurance required may not exceed $500,000 (Sec. 127.005(c)) |
| Practical effect | Higher agreed limits can support a larger indemnity, as long as both sides commit in writing | The insurance behind a one-way indemnity is capped by statute |
So why do operators push for mutual indemnity?
Because the statute rewards it. A one-way indemnity from a contractor to an operator can only be supported by up to $500,000 of required insurance. A mutual indemnity, where each side covers its own people and property regardless of fault, can be supported up to whatever limits both parties agreed to carry. That's the legal backbone of the knock-for-knock structure you see in most Texas MSAs.
The tradeoff for you: in a mutual scheme, your insurance is expected to protect the operator group for injuries to your own employees, even where the operator was negligent. That is why the MSA will also require additional insured status, a waiver of subrogation, and primary and non-contributory wording. Those endorsements are how the agreed insurance actually reaches the other party.
Losses Chapter 127 does not reach
Section 127.004 carves out several categories. The chapter does not apply to loss or liability arising from:
- personal injury, death, or property injury from radioactivity
- property injury from pollution, including cleanup and control of the pollutant
- property injury from reservoir or underground damage, including loss of oil, gas, water, or the well bore itself
- injury or damage from services to control a wild well to protect public safety or prevent depletion of natural resources
- the cost of controlling a wild well
The pollution carve-out matters for water haulers and anyone handling produced fluids: an indemnity for pollution property damage is outside Chapter 127 entirely, so the contract language controls. See oilfield pollution liability.
What to check in your own MSA
Read the indemnity section and the insurance section side by side and answer three questions:
- Is the indemnity mutual or one-way? Look at whether the operator also indemnifies you for injuries to its people.
- Does the MSA say in writing that the indemnity is supported by insurance? That language is what triggers Section 127.005.
- Do the limits in the insurance exhibit match on both sides? In a mutual scheme the obligation follows the coverage each party agreed to obtain, so mismatched or vague limits create arguments later.
Indemnity language is a legal question, and it should be reviewed by your attorney. Our part is making sure the policies you carry actually deliver what the contract says they will.
Insurance contracts still stand on their own
Section 127.006 says the chapter does not affect the validity of an insurance contract or benefits under the Texas workers compensation statutes. Even if an indemnity clause is unenforceable, your insurer’s obligations are governed by the policy and its endorsements.
Common questions
Does Chapter 127 require me to buy insurance from a mutual insurance company?
No. "Mutual" in Chapter 127 refers to a mutual indemnity obligation between the contracting parties. Any liability insurance, or qualified self-insurance, the parties agree to can support it.
Is a one-way indemnity from me to the operator void in Texas?
Not automatically. It can fall under the insurance exception if the parties agree in writing that it is supported by insurance, but Section 127.005(c) caps the amount of insurance required for a unilateral obligation at $500,000.
Does Chapter 127 apply to pipeline construction work?
Generally no. The definition of well or mine service excludes construction, maintenance, or repair of oil, natural gas liquids, or gas pipelines or fixed associated facilities, and transporting gas or NGLs by pipeline.
Does knock-for-knock cover the operator’s gross negligence?
That depends on the contract language and Texas case law, not just the statute. See our separate page on knock-for-knock and gross negligence, and have your attorney review the clause.
