Texas Oilfield Anti-Indemnity Act Explained

Short answer: the Texas Oilfield Anti-Indemnity Act, Chapter 127 of the Civil Practice and Remedies Code, voids an indemnity clause in a well or mine services agreement to the extent it protects a party against its own negligence. The exception in Section 127.005 keeps the clause alive if the parties agreed in writing that insurance supports it. That turns the indemnity question into an insurance limits question, and the limits are what you negotiate.

Most of the indemnity fights in Texas energy contracts are not about whether the clause was signed. They are about whether it survives the statute, and if it survives, how much money sits behind it. Those are two different problems with two different answers, and operators regularly win the first and lose the second.

This post walks the statute in the order it actually works: what it reaches, what it voids, how the insurance exception rescues the clause, and where the carve-outs sit. It is written for the operator, drilling contractor, or oilfield vendor reading a master service agreement, not for the courtroom.

Where the Act lives and what the Legislature said

Chapter 127 is titled Indemnity Provisions in Certain Mineral Agreements. The industry calls it the Texas Oilfield Anti-Indemnity Act, or TOAIA.

Section 127.002 contains the findings. The Legislature stated that the indemnity provisions in some of these agreements create an inequity for certain contractors, and that an agreement providing indemnity for a negligent indemnitee is against public policy. That is unusual candor for a statute, and it matters: a court reading an ambiguous clause knows what the Legislature was trying to stop.

Section 127.003 then does the work. Subject to the chapter's exceptions, a provision is void and unenforceable if it indemnifies a party against loss or liability for damage caused by the sole or concurrent negligence of the indemnitee, its agent or employee, or an individual contractor directly responsible to the indemnitee, where the loss arises from personal injury, death, or property injury.

Read that twice. The trigger is the indemnitee's own negligence, and concurrent negligence counts. A clause that would make a pressure pumping company pay for a loss the operator helped cause is exactly what the statute was built to void.

Which agreements the Act reaches

This is the first place contracts fall outside the statute, and parties are often surprised by which direction that cuts.

Chapter 127 applies to an agreement pertaining to a well for oil, gas, or water, or to a mine for a mineral. The definition in Section 127.001 covers written or oral agreements for well or mine services, and it extends to collateral agreements for furnishing or renting equipment and for transporting goods connected with those services. Well or mine service is defined broadly and includes drilling, well work, and shaft and structure work, with a catch-all for otherwise rendering services in connection with a well.

Section 127.001 excludes specified pipeline and fixed-facility activities and excludes joint operating agreements from covered well agreements. A mixed construction and well-service project needs review of each work order. Identify the work, location, contracting entities, and equipment supplied before assuming the statute applies.

Mutual versus unilateral: the distinction that controls the money

Section 127.001 defines two shapes of indemnity, and the entire economic analysis follows from which one you signed.

A mutual indemnity obligation is reciprocal. Each party agrees to indemnify the other, and the other's contractors and their employees, for injury, death, or property damage involving each side's own employees, contractors, and invitees arising out of performance of the agreement. This is the knock-for-knock structure that dominates Texas drilling contracts and master service agreements: I take care of my people and my property, you take care of yours, and fault does not drive the allocation.

A unilateral indemnity obligation runs one way. The indemnitor covers the other party for personal injury or death involving the indemnitor's own employees, agents, or its contractors' employees or agents, with nothing coming back the other direction.

Knock-for-knock is the norm for a reason that is purely statutory. When the 1989 amendments set the insurance framework, they placed no cap on the insurance that can support a mutual obligation. A unilateral obligation is capped. If you are the party receiving the indemnity, mutual is worth more. If you are the party giving it, mutual is usually the price of admission.

The insurance exception is the entire negotiation

Section 127.005 is where the money is.

Subsection (a) says the chapter does not apply to an agreement that provides for indemnity 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 subsection (b) or (c).

Then the two limits:

• Mutual indemnity obligation. The indemnity obligation is limited to the extent of the coverage and dollar limits of insurance or qualified self-insurance each party as indemnitor has agreed to obtain for the benefit of the other party as indemnitee. Section 127.005(b).
• Unilateral indemnity obligation. The amount of insurance required may not exceed $500,000. Section 127.005(c).

Three things follow, and all three get missed in practice.

First, the support has to be in writing. An MSA that recites a knock-for-knock indemnity but never ties it to insurance the indemnitor agreed to furnish is relying on a clause that Section 127.003 may void. The insurance schedule or exhibit is not administrative paperwork. It is the mechanism that makes the indemnity work.

Second, a mutual obligation is limited by the agreed insurance support. If the MSA says each party will indemnify the other and the insurance exhibit identifies primary and umbrella limits each party agreed to obtain for the other's benefit, subsection (b) limits the mutual obligation to that coverage and those dollar limits.

Third, the unilateral exception has a specific ceiling. When only one side indemnifies, Section 127.005(c) says the amount of insurance required may not exceed $500,000. A larger one-way demand should be reviewed by counsel rather than treated as if the statute plainly validates it.

The carve-outs in Section 127.004

The chapter does not apply at all to loss or liability arising from five categories:

• Personal injury, death, or property injury resulting from radioactivity
• Property injury resulting from pollution, including cleanup and control of the pollutant
• Property injury from reservoir or underground damage, including loss of oil, gas, other minerals, or water, or damage to the well bore
• Personal injury, death, or property injury from services performed to control a wild well, where the services are to protect public safety or prevent depletion of vital natural resources
• The cost of controlling a wild well, whether underground or above ground

Section 127.001 defines a wild well as one where the escape of oil or gas is unintended and cannot be controlled with normal drilling equipment.

These excluded exposures need review under the contract, other applicable law, and the insurance program. Exclusion from Chapter 127 does not establish that every allocation is enforceable. Whether that exposure is insured is then a question about the actual forms on the policy, including control of well, operators extra expense, and pollution coverage, which are not standard parts of a commercial general liability policy. TDI's general liability overview notes that pollution may be excluded entirely from a CGL form, with limited exceptions.

Two further provisions round out the chapter. Section 127.006 states that the chapter does not affect the validity of an insurance contract or benefits under the state's workers' compensation statutes. Section 127.007 preserves a surface estate owner's ability to obtain indemnity from a lessee, operator, contractor, or other person conducting mineral exploration or production on the owner's land.

Joint operating agreements sit outside

The definition of an agreement pertaining to a well expressly excludes a joint operating agreement, defined as an agreement among holders of working interests or operating rights for jointly exploring, developing, operating, or producing minerals.

Section 127.002 goes further and affirms that JOA provisions sharing costs or losses, including losses arising from a party's negligence, are generally enforceable unless the parties expressly exclude them in writing. Cost sharing among working interest owners is not the inequity the statute targeted.

The label on the document does not decide it. A services arrangement dressed as a joint operating agreement is still a services arrangement. If the real relationship is operator and vendor rather than co-owners sharing costs, expect Chapter 127 to be argued.

Where Chapter 127 meets the construction anti-indemnity act

Texas runs two anti-indemnity regimes that are easy to confuse.

Insurance Code Chapter 151, the Texas Anti-Indemnity Act, took effect January 1, 2012 and governs construction contracts. Section 151.102 voids a provision requiring indemnity for a claim caused by the indemnitee's negligence or fault, its statutory violation, or its breach of contract. Section 151.104 extends the same limit to additional insured requirements, so additional insured coverage is void to the extent it would provide what the indemnity could not.

Section 151.105 lists the exclusions, and one of them is agreements subject to Chapter 127 of the Civil Practice and Remedies Code. A wellsite agreement is analyzed under Chapter 127. A commercial building contract is analyzed under Chapter 151. The two statutes do not stack.

That line is clean in theory and messy on a mixed project. Tank battery foundations, compressor station buildings, gathering facilities, and access road work can look like construction and like well service depending on how the scope is written. If one master agreement covers both, the indemnity analysis can change by work order. We cover the construction side in the contractual risk transfer guide.

Review drafting before insurance is placed

Ask counsel whether the obligation is mutual in substance, whether fair-notice requirements apply, and how defense expenses interact with agreed insurance limits. Different words and facts can produce different outcomes.

Then compare the policies. A contractual defense promise can exceed the insurer's obligation. A recovery waiver can require an endorsement. A declarations limit does not establish coverage for an excluded exposure.

For some temporary placement arrangements, Chapter 127A requires disclosures before assignment. Where its definitions apply, the disclosure must describe indemnification obligations, insurance furnished for the subcontractor, amounts and limits, and how it covers tort and contractual indemnity liability.

What this means for the insurance program

The statute turns a legal clause into a purchasing decision, which means the insurance file and the contract file have to agree.

Match limits to the agreed support. Section 127.005(b) ties mutual indemnity to the coverage and dollar limits each party agreed to obtain for the other's benefit. Ask counsel about unequal limits or missing insurance rather than assuming the same outcome for every MSA.

Read additional insured coverage separately. Chapter 127 does not contain Chapter 151's parallel restriction on additional insured provisions. The endorsement and any incorporated contract terms determine coverage. A policy can tie coverage to assumed obligations, but this is a wording question. See the additional insured guide.

A certificate is not coverage. Texas Insurance Code Chapter 1811 governs certificates of insurance, and TDI's certificate FAQ is explicit that a certificate may not alter, amend, or extend the coverage in the policy. A certificate showing a blanket additional insured endorsement exists is not the same as the endorsement granting status to that party. Ask for the endorsement.

Waiver of subrogation needs to be obtained, not just promised. A waiver keeps a paying carrier, often the workers' compensation carrier, from coming back against the other party. A contract that requires one and a policy that does not carry it is a breach waiting to surface during settlement.

Watch the trucking and hauling pieces. Vendors hauling to and from the wellsite carry their own federal and state requirements that sit on top of the MSA. The commercial trucking insurance requirements guide covers those.

Questions to ask before signing

• Is this agreement one pertaining to a well under Section 127.001, or is it general construction under Insurance Code Chapter 151?
• Is the indemnity mutual or unilateral, and does the document say so clearly?
• Does a written provision state that insurance supports the indemnity, and does it reference the indemnity article specifically?
• What dollar amount of insurance does each party agree to obtain for the benefit of the other, and are the amounts equal?
• If the amounts differ, do you understand that the lower figure may cap both obligations?
• Do defense costs erode the supporting limit, and does the contract say which way?
• Do the policies actually carry the additional insured endorsements and waivers of subrogation the contract requires, by endorsement and not just by certificate?
• Is the indemnity conspicuous and does it satisfy the express negligence test?
• Are well control, pollution, and underground damage exposures addressed, given that Section 127.004 leaves them to the contract?
• Does the scope of work cross into activities a court might find too remote from the well for Chapter 127 to apply?

Frequently asked questions

What is the Texas Oilfield Anti-Indemnity Act?

Chapter 127 limits indemnity for a protected party's sole or concurrent negligence in covered well or mine agreements, subject to statutory exceptions.

Does Chapter 127 void every oilfield indemnity clause?

No. Section 127.005 creates a written insurance-support exception. Its requirements and limits must be assessed with the actual agreement.

How do mutual and unilateral obligations differ?

Mutual obligations are reciprocal as defined by the statute and are limited by agreed coverage and dollar amounts. Required insurance supporting a unilateral obligation may not exceed $500,000.

Does the statute govern every energy job?

No. Scope definitions exclude joint operating agreements and specified pipeline and fixed-facility activities. Counsel should review mixed scopes and work orders.

Does additional insured status automatically solve the problem?

No. Read the endorsement and incorporated contract terms. Chapter 127 does not contain Chapter 151's parallel additional insured restriction, but policy wording can still limit coverage.

What losses need a separate review?

Section 127.004 excludes specified radioactivity, pollution property damage, underground damage, and wild-well exposures. Other law, contract terms, and insurance determine the allocation.

Where Argo fits

Bring the master service agreement and insurance endorsements so Argo can compare the requested insurance with the policy. Have Texas oilfield counsel assess the indemnity wording.

Request an insurance policy review to compare your options.

This is general information about insurance and is not legal advice. Indemnity enforceability turns on the exact contract wording and the facts of the loss, coverage varies by carrier and form, and the policy issued controls. Have contract language reviewed by a Texas attorney.
