The RRC has issued one drilling permit (amended once), issued July 15, 2022, permitted to 10,200 ft.
It was permitted by Callon (Eagle Ford) LLC and has since transferred to Javelin Energy Partners Mgmt LLC on the wellbore schedule.

Its lease has reported 942K barrels of oil and 1.27M mcf of gas since April 2015, last reporting in July 2026. The lease carries 5 wells, so these are lease totals, not this well alone.
