In two recent cases, the Texas Supreme Court reviewed what are called “retained acreage” clauses in gas and oil leases. Consistent with recent precedent, the Court instructs that these clauses are to be interpreted based on the language used and that the intent of the parties is to be the guiding principle.
In Endeavor Energy Resources, L.P. v. Discovery Operating Inc., the conflict involved the interpretation of so-called “retained acreage” clauses where the parties intended the retained-acreage definition to be based on the plats filed with the Texas Railroad Commission (“RRC”). The Court also decided a companion case, XOG Operating LLC v. Chesapeake Exploration LP, that came to a different conclusion. The difference between the cases hinges on the language in the leases. We will discuss XOG separately.
