Oil Valley Petroleum v. Moore

Summary

The Oklahoma Supreme Court reversed the district court’s partial summary adjudication in favor of Moore and remanded for further proceedings, holding that the exhibits did not establish the well’s commercial profitability, that an overriding royalty interest is extinguished by the surrender of the underlying working interest unless fraud or a fiduciary breach is shown, and that prevailing‑party status for attorney‑fee awards must be determined by the trial court.
