How Does the Texas Oilfield Anti-Indemnity Act (CPRC Ch. 127) Affect Insurance Coverage in Oil & Gas Lawsuits?

Direct Answer Under Texas Law

In the Texas oil patch, Master Service Agreements (MSAs) between oil companies (Operators) and oilfield service contractors (Drillers, Frac Crews, Wireline) almost always contain 'knock-for-knock mutual indemnity' clauses. Under the Texas Oilfield Anti-Indemnity Act (TOAIA, CPRC Chapter 127), an oilfield agreement indemnifying a party for its own negligence is void UNLESS it is backed by liability insurance: (1) for a Unilateral Indemnity agreement, the obligation is capped at $500,000 (§ 127.005(c)); (2) for a Mutual Indemnity agreement, the obligation is enforceable up to the equal dollar amount of insurance that each party agreed as a 'safe harbor' to carry in support of the indemnity (often $5,000,000 to $10,000,000 under Ken Petroleum v. Questor, 24 S.W.3d 344 (Tex. 2000))!

Critical Texas Procedural Trap to Watch Out For

Why does TOAIA matter to an injured roughneck? Because even if your direct employer has workers' comp immunity, if you sue the Operator or another contractor, their MSA mutual-indemnity insurance layer ($5M–$10M+) often ends up funding the settlement!

Recommended Action Plan for Texas Claimants

Request all Master Service Agreements (MSAs) and Additional Insured / Mutual Indemnity Certificates of Insurance under TRCP 194.2(b)(7) in every Permian Basin and Eagle Ford case.
