The RRC has issued 2 drilling permits between 1990 and 2004, permitted to 1,800 ft.
It was permitted by Cottonwood Petroleum CO. and has since transferred to Jacobs C. E. CO. on the wellbore schedule.
Completion filings report 6 formation tops, including B/Coleman Jct Ls, T/Dothan Ls, T/Saddle Creek Ls, T/Cook Ss.
Its 2 leases have reported 1.98K barrels of oil and 11 mcf of gas since January 1993, last reporting in November 2007. The leases carry 3 wells, so these are lease totals, not this well alone.
