The RRC has issued one drilling permit (amended twice), issued July 27, 2010, permitted to 10,829 ft.
It was permitted by Aurora Resources Corporation and has since transferred to Crescent Energy Operating LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Carrizo, Olmos, Eagle Ford.
Its lease has reported 1.6M barrels of oil and 2.44M mcf of gas since December 2010, last reporting in July 2026. The lease carries 5 wells, so these are lease totals, not this well alone.
