The RRC has issued one drilling permit, issued November 2, 1982, permitted to 6,500 ft.
It was permitted by Hamilton, J. R. & Archer, J.R. and has since transferred to Hamilton J. R. on the wellbore schedule.
Completion filings report 4 formation tops, including Miocene (undifferentiated), Frio, Transition, First Hockley.
Its 2 leases have reported 9.53K barrels of oil and 19.8K mcf of gas since January 1993, last reporting in March 2008. The leases carry 2 wells, so these are lease totals, not this well alone.
