Cook Ranch 85 #71 (API 42-417-39173) is a well in Shackelford County operated by Stasney Well Service LLC, completed December 7, 2011 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued March 21, 2011, permitted to 2,000 ft.

It was permitted by Stasney, H. R. & Sons, Ltd. and has since transferred to Stasney Well Service LLC on the wellbore schedule.

Completion filings report 4 formation tops, including Coleman Junction, Dothan Ls, Noodle Creek Ls, Saddlecreek Ls.

Its lease has reported 6.29K barrels of oil and 12K mcf of gas since November 2008, last reporting in July 2026. The lease carries 3 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.
