Walnut Bend Field Unit #2359 (API 42-097-31504) is a well in Cooke County operated by Sydri Operating LLC, completed September 18, 2007 and listed as producing on the RRC schedule.
The RRC has issued 3 drilling permits between 1979 and 1985, permitted to 5,590 ft.
It was permitted by Arco Oil & Gas CO. and has since transferred to Sydri Operating LLC on the wellbore schedule.
Completion filings report 12 formation tops, including Cox, Bruhlmeyer, Hudspeth, Hud D.
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.

Surface location
No coordinates on the permit record yet. The RRC's GIS record usually lands within days of issuance; historical master-file permits never carry one.
Wells nearby
Every well with a location on file around this well, in any state, nearest first.
Texas locations come from drilling permits, so most older Texas wells have none and are not listed.
