The Fourth Circuit affirmed the District Court for the Northern District of West Virginia's summary judgment for defendants Antero Resources Corporation, Key Oil Company, and Franklin L. Butler on Count II of plaintiff McArdle Family Partnership's breach of contract claim concerning oil and gas royalty interests. The court agreed that a May 30, 1996 assignment from James Drilling Corporation and the Shearers to Key Oil was a clear, broad conveyance of all their interests in the relevant leases, with no exceptions or reservations, and therefore James Drilling Corporation conveyed no royalty interests to MFP in 2008. The case was affirmed in part, vacated in part, and remanded.
