The RRC has issued one drilling permit (amended once), issued October 13, 1998, permitted to 8,500 ft.
It was permitted by Concho Resources Inc. and has since transferred to Estancia Oil & Gas LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Yates, San Andres, Spraberry.
Its 2 leases have reported 489K barrels of oil and 143K mcf of gas since January 1993, last reporting in July 2026. The leases carry 19 wells, so these are lease totals, not this well alone.
