The RRC has issued one drilling permit, issued May 9, 1986, permitted to 3,000 ft.
It was permitted by Parten, J. R. and has since transferred to Ocean Energy Inc. on the wellbore schedule.

Its lease has reported 21K barrels of oil and 6.9K mcf of gas since January 1993, last reporting in December 2002. The lease carries 4 wells, so these are lease totals, not this well alone.
