Cooke County · Walnut Bend (Consolidated) field · Vertical

Walnut Bend Field Unit #20-11W (API 42-097-01017) is a plugged well in Cooke County, plugged March 5, 2020, last operated by Sydri Operating LLC.

The RRC has issued 2 drilling permits between 1978 and 1979, permitted to 5,518 ft.

It was permitted by Arco Oil & Gas CO. and has since transferred to Sydri Operating LLC on the wellbore schedule.

Its 2 leases have reported 6.69M barrels of oil and 1.38M mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 370 wells, so these are lease totals, not this well alone.
