Short answer
If you service oil, gas or water wells in Texas, probably yes. Chapter 127 of the Civil Practice and Remedies Code applies to agreements for "well or mine service," which the statute defines to include drilling, reworking, repairing, testing, treating, perforating, acidizing and logging, and transporting or storing oil, produced water, brine and other liquids, plus equipment rental and incidental transportation tied to that work.
- Pipeline construction and repair and gas or NGL pipeline transportation are excluded, and so are joint operating agreements.
- Even inside the chapter, some losses are carved out, including pollution property damage and wild well control. If it applies, the indemnity in your MSA generally needs agreed insurance behind it.
What the statute covers
Chapter 127 applies to an "agreement pertaining to a well for oil, gas, or water or to a mine for a mineral." Under Section 127.001, that means a written or oral agreement about rendering well or mine services, or an agreement to perform part of those services or a collateral act, "including furnishing or renting equipment, incidental transportation," and other goods and services furnished in connection with the services.
"Well or mine service" covers, among other things, "drilling, deepening, reworking, repairing, improving, testing, treating, perforating, acidizing, logging, conditioning," as well as purchasing, gathering, storing or transporting oil, brine water, fresh water, produced water, condensate, petroleum products or other liquid commodities, and other services for a well drilled to produce or dispose of oil, gas, other minerals or water. It also covers mine shafts and similar structures.
Read that list against typical service trades:
| Your work | Statute language it lines up with |
|---|---|
| Well servicing and workover | Reworking, repairing, improving, testing |
| Acidizing, hot oil and frac support | Treating, acidizing, conditioning, other services for a well |
| Wireline and logging | Logging, perforating, testing |
| Water hauling and SWD | Transporting or storing produced water and brine; services for a disposal well |
| Roustabout and lease maintenance | Repairing, improving, other services for a well |
| Equipment rental and hauling for well work | Furnishing or renting equipment, incidental transportation |
What is outside the statute
The definition of well or mine service expressly excludes:
- purchasing, selling, gathering, storing or transporting gas or natural gas liquids by pipeline or fixed associated facilities, and
- construction, maintenance or repair of oil, natural gas liquids or gas pipelines or fixed associated facilities.
A joint operating agreement among working interest owners is also not covered.
Section 127.004 then carves certain losses out of the chapter even when the work is covered: injury or damage from radioactivity; property injury from pollution, including cleanup and control; reservoir or underground damage, including loss of oil, gas, water or the well bore; injury or damage from services to control a wild well to protect public safety or prevent depletion of vital natural resources; and the cost of controlling a wild well. Indemnities for those losses are governed by the contract and general law, not Chapter 127.
Section 127.007 also leaves a surface owner free to seek indemnity from the lessee, operator or contractor working on its land.
If it applies, what changes
Inside the chapter, Section 127.003 voids indemnity for losses caused by the indemnitee's "sole or concurrent negligence," or that of its agent, employee or "an individual contractor directly responsible to the indemnitee," for personal injury, death or property injury.
The exception is insurance. Under Section 127.005, the chapter does not apply if the parties agree in writing that the indemnity will be supported by liability insurance furnished by the indemnitor. A mutual indemnity is then limited to the coverage each party agreed to obtain for the other. A one-way indemnity can be supported by required insurance of no more than $500,000.
For your insurance program, that means the limits in the MSA exhibit, and the wording of your own policies, can set how far the indemnity reaches. See does Chapter 127 require mutual insurance and the Texas oilfield anti-indemnity act.
Chapter 127: how insurance caps indemnity
Work across state lines
Chapter 127 is a Texas statute. If you cross into New Mexico, that state has its own oilfield anti-indemnity law, NMSA Section 56-7-2. As amended in 2003, it voids indemnity for the indemnitee's sole or concurrent negligence in agreements pertaining to oil, gas or water wells, and it also voids insurance or other contract provisions that would achieve the same result. There is no Texas-style insurance exception in that text. See Hobbs and Carlsbad for New Mexico work, and the Haynesville page for Louisiana.
Which state's law governs a given job depends on the contract and where the work happens. That is a question for your attorney, and the answer can change what your insurance needs to do.
Common questions
Does Chapter 127 cover water well work?
Yes. The statute applies to agreements pertaining to a well for oil, gas, or water, and the service definition includes services for wells drilled to produce or dispose of water.
I build gathering lines. Am I covered?
Probably not for that work. The definition excludes construction, maintenance or repair of oil, NGL or gas pipelines and fixed associated facilities. Have your attorney confirm for your specific scope.
Does Chapter 127 make my insurance void?
No. Section 127.006 says the chapter does not affect the validity of an insurance contract or workers’ comp benefits.
Does the statute apply to hauling equipment to a well?
The definition of an agreement pertaining to a well includes incidental transportation and furnishing or renting equipment in connection with well services.
