The RRC has issued one drilling permit, issued May 24, 1991, permitted to 5,000 ft.
It was permitted by Townsend The CO. and has since transferred to R & R Well Service on the wellbore schedule.
Completion filings report 4 formation tops, including Palo Pinto, Goen, Jennings Sand, Lower Gardner.
Its lease has reported 8.93K barrels of oil and 4.79K mcf of gas since January 1993, last reporting in April 2003. The lease carries 3 wells, so these are lease totals, not this well alone.
