The RRC has issued one drilling permit, issued May 14, 1990, permitted to 4,999 ft.
It was permitted by Throco, Inc. and has since transferred to Breck Operating Corp. on the wellbore schedule.
Completion filings report one formation top, including Mississippian.
Its lease has reported 305 barrels of oil and 61 mcf of gas since January 1993, last reporting in February 2016. The lease carries 2 wells, so these are lease totals, not this well alone.
