The RRC has issued 4 drilling permits (amended once) between 1984 and 2026, permitted to 11,300 ft.
It was permitted by Mud Creek Operating, LLC and has since transferred to Map Production CO. Inc. on the wellbore schedule.
Completion filings report 7 formation tops, including Goodland, Glen Rose, Rodessa, Pettit.
Its 3 leases have reported 32.1K barrels of oil and 110K mcf of gas since January 1993, last reporting in July 2026. The leases carry 4 wells, so these are lease totals, not this well alone.
