Windham -C- #11 (API 42-461-36857) is a well in Upton County operated by Civitas Permian Operating LLC, completed July 26, 2011 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued July 27, 2010, permitted to 10,500 ft.

It was permitted by Merit Energy Company and has since transferred to Civitas Permian Operating LLC on the wellbore schedule.

Completion filings report 3 formation tops, including Spraberry, Dean, Wolfcamp.

Its lease has reported 453K barrels of oil and 1.32M mcf of gas since January 1993, last reporting in July 2026. The lease carries 12 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.
