It’s often helpful when courts are asked to construe joint operating agreements. Not always, though. Courts sometimes don’t understand or fail to take into account industry custom and practice and the underlying purposes behind the JOA, especially the Model Form. Evans Resources LP v. Petroplex Energy Inc. appears, at first blush, not to be one of those cases on the facts considered by the trial and appellate courts.
The dispute
Evans granted an oil and gas lease to Diamondback for minerals over 651 acres in Midland County. Diamondback as operator and the Anwars (Petroplex) as non-operators entered into what appears to be an AAPL Model Form 610 Joint Operating Agreement to which Diamondback contributed the Evans acreage.
Diamondback released portions of the lease effective as of November 2018. Diamondback drilled horizontal wells that included the Evans expired acreage. Evans sued the Anwars seeking royalties that Diamondback allegedly paid to the Anwars on production from those wells. The claim was the Anwars owed a duty to pay received royalties to Evans because the JOA assigned Diamondback’s royalty obligation to the Anwars. Evans also asserted that it and Diamondback became co-tenants in the released acreage.
How the courts saw the claims.
Not favorably. The Court of Appeals affirmed summary judgment for Anwars on all claims. The basis for the ruling was the words of the JOA (Homework: retrieve a copy and follow along if you wish).
Evans lacked standing to enforce the JOA’s royalty provisions because:
- Evans had no privity of estate with the Anwars (Art. III.B disclaims cross-conveyances of contributed interests);
- Evans was not a third-party beneficiary (Art. VII.A expressly disclaims third-party liability, and Texas law disfavors such claims anyway);
- Evans had no privity of contract with the Anwars (Under Art. VII.A each party is responsible only for its obligations and no party is obligated to satisfy the default of any other party. Art. III.B requires each party to pay or deliver burdens on its share of production from the Contract Area).
The Court also rejected Evans’s co-tenancy/money-had-and-received claim. There was no co-tenancy relationship between the Anwars and Evans that would create a duty to pay Evans profits from co-tenant operations. Further, the Anwars presented evidence via an affidavit from a Diamondback employee that they received no proceeds attributable to Evans. Rather, they received only revenue based on the leases they contributed to the JOA. Evans’ was not one of those leases.
Lagniappe
Evans knows the courthouse well. While maybe not a “vexatious litigant”, it (or them, or he, or her) is persistent. The Court noted that this is Evans’ third defeat in suits against Diamondback or related parties relating to the same 651 acres. The other opinions are here and here.
