The RRC has issued one drilling permit (amended once), issued May 27, 2014, permitted to 12,000 ft.
It was permitted by Sanchez Oil & Gas Corporation and has since transferred to Javelin Energy Partners Mgmt LLC on the wellbore schedule.
Completion filings report 10 formation tops, including Yegua, Wilcox, Navarro, Escondido.
Its lease has reported 483K barrels of oil and 488K mcf of gas since March 2012, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
