The RRC has issued 2 drilling permits (amended once) between 2003 and 2004, permitted to 4,000 ft.
It was permitted by Tanglewood Oil & Gas CO. and has since transferred to Three J Energy Inc. on the wellbore schedule.
Completion filings report 3 formation tops, including Anacacho, Austin Chalk, Eagle Ford.
Its lease has reported 10.5K barrels of oil and 698 mcf of gas since November 2003, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
