The ongoing saga of Self, et al. v. BPX Operating Co., et al., has drawn a large audience due to its potential economic repercussions for Haynesville producers and mineral owners. Recall the question: Can the operator of a well on a Louisiana compulsory drilling unit who markets unleased mineral owners’ share of unit production deduct post-production costs from the mineral owners’ share of proceeds? The federal district court revisited this dispute and, for now anyway, the answer is yes.
The facts
The Selfs own a tract in a unit formed by the Louisiana Office of Conservation in Red River Parish. BPX is the operator. The Selfs have no lease and have not made arrangements to sell their share of production, so BPX markets the gas for them. La. R.S. 30:10(A)(3) requires the operator to pay the unleased mineral owner its “pro rata share of the proceeds of the sale of production”. The Selfs, suing on behalf of a putative class, alleged that netting post-production costs out of proceeds is improper per se.
The long road to where we are
In 2022, on a BPX motion for partial dismissal of Count 1 of plaintiffs’ complaint, the trial court ruled for BPX on the theory of negotiorum gestio, a Louisiana civil-law doctrine under which someone who manages another’s affairs may be reimbursed. The Fifth Circuit certified the question to the Louisiana Supreme Court . which held that the doctrine does not fit; a gestor acts “without authority” and an operator selling under the statute acts with statutory authority. Upon remand, BPX returned with alternative theories not addressed in the first round, including co-ownership, tacit mandate, legal representation, and unjust enrichment.
The ruling
In the end, the Court didn’t need BPX’s Civil Code theories to reach a conclusion. The answer came from a different Fifth Circuit case, Dow Construction, LLC v. BPX Operating Co.
La. R.S.30:103.1 requires the operator to send unleased mineral owners sworn, itemized reports of costs, including “operating costs and expenses” and “all other unit costs allocable to an owner”. An operator who fails to report surrenders its right to demand contribution for “the costs of the drilling operations”. Under Dow (citing Louisiana appellate opinions), post-production costs fall within that forfeiture provision. According to the Court here, Dow construed the meaning of operating costs consistently within the confines of both 30:10 and 30:103.1 et seq, thereby promoting statutory harmony and the consistent interpretation of conservation laws
The Court followed Dow to its logical end. A cost must be chargeable before an operator can forfeit the right to charge it. In the Court’s words, “there can be no reporting or forfeiture of costs for which an operator bears full responsibility”. A contrary rule, the Court said, would produce absurd results. The Court also read “operating costs” consistently across Sections 30:10 and 103.1. Post-production costs are therefore deductible as operating costs under 30:10(A)(2)(b)(i), and BPX’s motion to dismiss was granted.
The case is not over. There will be appeals, and the ruling is only on a motion for partial dismissal.
