Cooke County · Walnut Bend (Consolidated) field  · Vertical

Walnut Bend Field Unit #256 (API 42-097-05352) is a former disposal or injection well in Cooke County, last operated by Sydri Operating LLC; its UIC permit is no longer active.

The RRC has issued one drilling permit, issued August 16, 2005, permitted to 5,000 ft.

It was permitted by Gruy Petroleum Management CO. and has since transferred to Sydri Operating LLC on the wellbore schedule.

Completion filings report 3 formation tops, including Bruylmeyer, Ramsey, Best.

Its 2 leases have reported 6.69M barrels of oil and 1.38M mcf of gas since January 1993, last reporting in July 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.
