It was permitted by Mitchell Energy Corporation and has since transferred to Mash Oilfield Services LP on the wellbore schedule.
Completion filings report one formation top, including Caddo.
Its 2 leases have reported 46.4K barrels of oil and 154K mcf of gas since March 1998, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
