Wiederkehr L. #97 (API 42-131-05066) is a well in Duval County operated by Black Gold Operating CO LLC, completed November 8, 1979.
The RRC has issued 2 drilling permits between 1979 and 2003, permitted to 5,480 ft.
It was permitted by El Campo Operating, LLC and has since transferred to Black Gold Operating CO LLC on the wellbore schedule.
Completion filings report one formation top, including Gas Stringer.
Its 2 leases have reported 52.7K barrels of oil and 114K mcf of gas since January 1993, last reporting in July 2026. The leases carry 11 wells, so these are lease totals, not this well alone.
