North Walnut Bend Unit #11 (API 42-097-31365) is a well in Cooke County operated by Sydri Operating LLC, completed September 20, 1988.

The RRC has issued one drilling permit, issued March 13, 1979, permitted to 2,650 ft.

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

Completion filings report 4 formation tops, including Canyon, Strawn, Hudspeth, Montgomery.

Its lease has reported 633K barrels of oil and 152K mcf of gas since January 1993, last reporting in July 2026. The lease carries 26 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit, with 341K barrels injected in the 12 months reported through August 2025.

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