Devon Energy Production Co., L.P. v. Sheppard (Opinion)
Annotate this Case
The Supreme Court affirmed the summary judgment in favor of Landowners in this oil-and-gas dispute over how to calculate Landowners' royalty under the terms of a mineral lease with Producers, holding that there was no error in the proceedings below.
At issue in a declaratory judgment action was whether, based on language in the subject leases, Landowners' royalty was payable not only on gross proceeds but also on an unaffiliated buyer's post-sale postproduction costs if the producers' sales contracts stated that the sales price had been derived by deducting such costs from published index prices downstream from the point of sale. The trial court granted summary judgment for Landowners as to these types of marketing arrangements. The Supreme Court affirmed, holding that the broad language of the lease unambiguously contemplated such a royalty base.
