Cerf #1B (API 42-349-34645) is a well in Navarro County operated by Corsicana Oil & Gas, completed July 12, 2001 and listed as no production on the RRC schedule.
The RRC has issued one drilling permit, issued June 7, 2001, permitted to 2,300 ft.
It was permitted by Reilly, K. L. and has since transferred to Corsicana Oil & Gas on the wellbore schedule.
Completion filings report 3 formation tops, including Nacatoch, Pecan Gap, Wolf City.
Its lease has reported 29.9K barrels of oil since January 2000, last reporting in July 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
Operator of record
Permitted by Reilly, K. L.; the EWA schedule now lists a different operator.
