The RRC has issued one drilling permit, issued January 24, 2011, permitted to 7,552 ft.
It was permitted by Anadarko E&P Company LP and has since transferred to Javelin Energy Partners Mgmt LLC on the wellbore schedule.

Its 3 leases have reported 1.38M barrels of oil and 4.09M mcf of gas since July 2010, last reporting in July 2026. The leases carry 16 wells, so these are lease totals, not this well alone.
