The RRC has issued one drilling permit, issued September 20, 1988, permitted to 7,650 ft.
It was permitted by Voskamp Exploration, Inc. and has since transferred to Estancia Oil & Gas LLC on the wellbore schedule.

Its 2 leases have reported 316K barrels of oil and 99.8K mcf of gas since January 1993, last reporting in July 2026. The leases carry 14 wells, so these are lease totals, not this well alone.
