Walnut Bend Field Unit #1581 (API 42-097-31735) is a well in Cooke County operated by Sydri Operating LLC, completed December 4, 2006 and listed as producing on the RRC schedule.

The RRC has issued 4 drilling permits between 1981 and 2001, permitted to 5,500 ft.

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

Completion filings report 10 formation tops, including Hudspeth, Main Snuggs, Snuggs, Snuggs "D".

Its 2 leases have reported 8.16M barrels of oil and 1.91M mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 427 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.
