The RRC has issued one drilling permit (amended 3 times), issued October 27, 2017, permitted to 7,166 ft.

It was permitted by SN EF Maverick, LLC and has since transferred to Javelin Energy Partners Mgmt LLC on the wellbore schedule.

Its lease has reported 873K barrels of oil and 3.27M mcf of gas since August 2018, last reporting in July 2026. The lease carries 6 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
