The RRC has issued one drilling permit (amended twice), issued June 22, 2011, permitted to 10,376 ft.
It was permitted by Carrizo Oil & Gas, Inc. and has since transferred to Javelin Energy Partners Mgmt LLC on the wellbore schedule.

Its lease has reported 1.43M barrels of oil and 1.53M mcf of gas since August 2011, last reporting volume in March 2026. The lease carries 7 wells, so these are lease totals, not this well alone.
