The RRC has issued one drilling permit, issued September 24, 2012, permitted to 2,500 ft.
It was permitted by Four C Oil & Gas Corp. and has since transferred to Saguaro Petroleum LLC on the wellbore schedule.
Completion filings report 2 formation tops, including Yates, San Andres.
Its lease has reported 1.25M barrels of oil and 35.7K mcf of gas since November 1993, last reporting in July 2026. The lease carries 38 wells, so these are lease totals, not this well alone.
