The RRC has issued one drilling permit, issued July 20, 1977, permitted to 7,300 ft.
It was permitted by Enerco Exploration & Mgmt. CO. and has since transferred to First Rock Inc. on the wellbore schedule.
Its lease has reported 18.3K barrels of oil and 15.1K mcf of gas since January 1993, last reporting in December 2001. The lease carries 2 wells, so these are lease totals, not this well alone.
