The RRC has issued one drilling permit, issued April 29, 2004, permitted to 7,026 ft.
It was permitted by Henry Petroleum LP and has since transferred to Highmark Energy Operating LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Clear Fork, Tubb, Top Fullerton.
Its lease has reported 5.61M barrels of oil and 1.5M mcf of gas since February 1995, last reporting volume in April 2026. The lease carries 79 wells, so these are lease totals, not this well alone.
