The RRC has issued one drilling permit, issued May 31, 2013, permitted to 7,495 ft.
It was permitted by Anadarko E&P Onshore LLC and has since transferred to Javelin Energy Partners Mgmt LLC on the wellbore schedule.

Its 2 leases have reported 15.8M barrels of oil and 43.4M mcf of gas since June 2010, last reporting in July 2026. The leases carry 81 wells, so these are lease totals, not this well alone.
