Panhandle Eastern Pipe Line Co. v. Isaacson

Isaacson's term mineral interest, reserved in a deed covering portions of two sections, was later subjected to an Oklahoma Corporation Commission spacing order treating the sections as separate drilling units; a producing test well was drilled only within the unit covering one section, and Isaacson argued this production extended his entire deeded interest, including the other section, while the lessees argued the interest in the non-producing section had terminated.
