The RRC has issued one drilling permit, issued November 30, 1989, permitted to 1,800 ft.
It was permitted by Enwest Corporation and has since transferred to Vinson Exploration on the wellbore schedule.
Completion filings report 2 formation tops, including Queen, Grayburg.
Its 2 leases have reported 30K barrels of oil and 90.6K 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.
