The RRC has issued 3 drilling permits between 1978 and 2002, permitted to 7,981 ft.
It was permitted by Acock/Anaqua Operating CO., LC and has since transferred to Atlantic Richfield CO. on the wellbore schedule.
Completion filings report 3 formation tops, including Greta, Catahoula, Top Of Sinton.
Its 3 leases have reported 124K barrels of oil and 353K mcf of gas since January 1993, last reporting in July 2026. The leases carry 9 wells, so these are lease totals, not this well alone.
