Cerf Eugenia #1G (API 42-349-34892) is a well in Navarro County operated by KO Operating LLC, completed June 24, 2009 and listed as shut in on the RRC schedule.
The RRC has issued one drilling permit, issued May 8, 2009, permitted to 2,200 ft.
It was permitted by Corsicana Oil & Gas and has since transferred to KO Operating LLC on the wellbore schedule.
Completion filings report 2 formation tops, including Nachatoch, Pecan Gap.
Its lease has reported 20K barrels of oil since November 2001, last reporting in July 2026. The lease carries 6 wells, so these are lease totals, not this well alone.
