Walnut Bend Field Unit #23-4 (API 42-097-02440) is a well in Cooke County operated by Sydri Operating LLC, completed January 22, 2012 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued December 19, 1977, permitted to 4,963 ft.

It was permitted by Atlantic Richfield CO. and has since transferred to Sydri Operating LLC on the wellbore schedule.

Completion filings report 3 formation tops, including Cox, Bruhlmeyer, Consolidated.

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.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
