Oil Valley Petroleum v. Moore

Summary

The Oklahoma Supreme Court vacated the Court of Civil Appeals' decision granting Clay Moore partial summary adjudication and reversed it, remanding for further proceedings. The Court held that the record did not establish the commercial profitability of the Ball #1‑24 well required for the habendum clause, that an overriding royalty interest is extinguished by the surrender of the underlying working interest unless fraud or breach of fiduciary duty is shown, and that prevailing‑party status for attorney‑fee awards must be determined by the trial court.
