The RRC has issued one drilling permit, issued May 14, 1997, permitted to 6,000 ft.
It was permitted by Coda Energy, Inc. and has since transferred to Kerr-Mcgee Oil & Gas Onshore LP on the wellbore schedule.

Its lease has reported 382K barrels of oil and 867K mcf of gas since January 1993, last reporting in May 2006. The lease carries 10 wells, so these are lease totals, not this well alone.
