The RRC has issued one drilling permit, issued July 12, 2017, permitted to 11,000 ft.
It was permitted by Carrizo (Eagle Ford) LLC and has since transferred to Javelin Energy Partners Mgmt LLC on the wellbore schedule.

Its lease has reported 774K barrels of oil and 1.61M mcf of gas since December 2012, last reporting in July 2026. The lease carries 9 wells, so these are lease totals, not this well alone.
