Cerf-A #2 (API 42-349-32828) is a plugged well in Navarro County, plugged March 13, 2018, last operated by KO Operating LLC.
The RRC has issued one drilling permit, issued September 3, 1982, permitted to 2,200 ft.
It was permitted by H. T. H. Oil CO. and has since transferred to KO Operating LLC on the wellbore schedule.
Completion filings report one formation top, including Lower Nachatoch.
Its 2 leases have reported 97.9K barrels of oil and 22.6K mcf of gas since January 1993, last reporting in July 2026. The leases carry 28 wells, so these are lease totals, not this well alone.
Operator of record
Permitted by H. T. H. Oil Co.; the EWA schedule now lists a different operator.
