The RRC has issued one drilling permit, issued September 15, 1986, permitted to 2,999 ft.
It was permitted by Quita, Inc. and has since transferred to Dorondoco Operating CO. Inc. on the wellbore schedule.

Its 2 leases have reported 27K barrels of oil and 37.6K mcf of gas since January 1993, last reporting in July 2026. The leases carry 9 wells, so these are lease totals, not this well alone.
