The RRC has issued one drilling permit (amended twice), issued February 9, 1988, permitted to 6,000 ft.
It was permitted by Mitchell Energy Corporation and has since transferred to Bulwark Oil & Gas LLC on the wellbore schedule.
Completion filings report 2 formation tops, including Caddo, Ellenburger.
Its lease has reported 102K barrels of oil and 193K mcf of gas since January 1993, last reporting in July 2026. The lease carries 14 wells, so these are lease totals, not this well alone.
