Fifth Circuit Clarifies Insurance Floor and Ceiling in Oilfield Mutual Indemnity Agreements Under TOAIA

Century Surety Company v. Colgate Operating, L.L.C. United States Court of Appeals, Fifth Circuit 23-50530 resolved
By Joel Reese · July 06, 2026 United States Court of Appeals, Fifth Circuit

Century Surety, as subrogee of Triangle Engineering after paying $5 million on a personal injury settlement, sought reimbursement from Colgate Operating under a master service agreement requiring indemnity insurance "not less than $5 million" or the maximum amount permitted without violating TOAIA. The Fifth Circuit affirmed summary judgment for Colgate, holding that the MSA's insurance language established both a floor and ceiling of $5 million, rendering Colgate's $75 million excess policy irrelevant to Triangle's indemnity rights.

Fifth Circuit TOAIA Mutual Indemnity Master Service Agreement Oilfield Insurance

Background and Business Context

This dispute arose from a February 2020 oilfield accident in Pecos County, Texas, where Jeremy Miller, an employee of a contractor, was crushed and injured by a pipe rack while working on a well operated by Colgate Operating, L.L.C. Colgate had hired Triangle Engineering, L.P., an oilfield consultancy, to provide a workover consultant to coordinate the installation of an electronic submersible pump. Triangle's consultant, Brian Bell, was coordinating with Colgate's other contractors when the accident occurred. The parties had entered into Colgate's form Master Services/Sales Agreement ("MSA") in April 2017, which contained mutual indemnity provisions and insurance requirements governed by Texas law and the Texas Oilfield Anti-Indemnity Act ("TOAIA").

The Insurance Coverage Dispute

After Miller and his wife sued multiple parties including Colgate and Triangle, the case settled for an undisclosed total. Triangle's primary insurer, Hallmark National Insurance Company, paid $1 million, and its excess insurer, Century Surety, paid $5 million pursuant to Triangle's policies. Notably, Colgate's insurer, Markel International Insurance, paid $6 million into the settlement for the benefit of Triangle and Bell. Century, acting as Triangle's subrogee, then sued Colgate for breach of contract, seeking reimbursement of the $5 million it paid toward the Miller settlement. The central question was whether Colgate's obligation to indemnify Triangle was limited to $5 million under the MSA, or whether Triangle could access Colgate's $75 million excess liability policy.

The MSA's Insurance Requirements and TOAIA

The MSA required both Colgate and Triangle to purchase indemnity insurance with limits the lesser of: (1) "not less than $5 million", or (2) "the maximum amount which may be required by law, if any, without rendering this mutual indemnification obligation void, unenforceable or otherwise inoperative." While Colgate purchased a $1 million general liability policy and a $75 million excess liability policy from Markel, Triangle purchased only a $1 million general liability policy and a $5 million excess liability policy from Century. The district court had rejected affidavits from Colgate's vice president and Triangle's sole member regarding their subjective intentions when signing the MSA, finding them inadmissible under the parol evidence rule. The Fifth Circuit agreed, holding that

the parol evidence rule prohibits extrinsic evidence of subjective intent that alters a contract's terms, but does not prohibit consideration of surrounding circumstances that inform, rather than vary from or contradict, the contract text.

The Fifth Circuit's Analysis

The Fifth Circuit affirmed the district court's grant of summary judgment to Colgate, though on different grounds. The court held that the MSA's insurance language established both a floor and a ceiling of $5 million for the parties' mutual indemnity obligations. The court reasoned that

once parties agreed to mutually indemnify each other for the same amount, there was no risk of agreement being invalidated by Texas Oilfield Anti-Indemnity Act (TOAIA), and operator's excess policy with $75 million limit provided no rights to consultant.
The court explained that TOAIA was originally passed in 1973 to prevent oil well operators from shifting liability onto contractors through one-sided indemnification agreements, but it expressly authorized mutual indemnification agreements supported by liability insurance. Once the parties agreed to the $5 million threshold, they satisfied TOAIA's requirements and eliminated any risk of the agreement being void. The court distinguished the district court's reliance on the "lowest common denominator rule" from Ken Petroleum Corp. v. Questor Drilling Corp., 24 S.W.3d 344 (Tex. 2000), noting that Ken Petroleum interpreted a prior version of the statute.

Implications for Oilfield Service Agreements

This decision provides critical guidance for drafting mutual indemnity and insurance provisions in oilfield master service agreements. Operators and contractors must carefully consider whether insurance requirement language creates only a floor or both a floor and ceiling for indemnity obligations. The Fifth Circuit's interpretation means that specifying a minimum insurance amount coupled with language about avoiding TOAIA violations can effectively cap mutual indemnity obligations at that minimum amount, even where one party purchases substantially more insurance coverage. For operators with large excess policies, this ruling clarifies that such policies may not be accessible to contractors unless the MSA explicitly provides higher insurance ceilings. The decision also reinforces the parol evidence rule's application in this context, making clear that parties cannot use affidavits about subjective intent to alter unambiguous contract terms. In-house counsel should review existing MSAs to determine whether insurance provisions create unintended ceilings on indemnity obligations and consider whether current insurance requirements adequately protect their companies' interests in light of this precedent.
