XOG Operating, LLC v. Chesapeake Exploration Limited Partnership (Opinion)Annotate this Case
The Supreme Court affirmed the judgment of the court of appeals in this case requiring interpretation of retained-acreage provisions in oil-and-gas lease instruments, holding that acreage “included within the proration unit for each well…prescribed by field rules” refers to acreage set by the field rules, not acreage assigned by the operator.
XOG Operating, LLC conveyed to Chesapeake Exploration Limited Partnership and Chesapeake Exploration, LLC (collectively, Chesapeake) its rights as lessee under four oil-and-gas leases in three sections of land. Under a retained-acreage provision, the assigned interest would revert to XOG after the primary term. As relevant to appeal, Chesapeake would retain for each well drilled the acreage “included within the proration…unit” “prescribed by field rules.” The acreage not retained by Chesapeake would revert to XOG on termination of the assignment. Chesapeake completed six wells during the primary term of the assignment, five of which were located in an area for which the Railroad Commission had promulgated field rules. The sixth well was located in an area for which there were no field rules. In Chesapeake’s view, it retained all of the assigned acreage. XOG sued Chesapeake to construe the retained-acreage provision. The Supreme Court affirmed the trial court's decision that the none of the land at issue reverted to XOG under the retained-acreage provision.
