Cook W. I. #6488A (API 42-417-38855) is a plugged well in Shackelford County, plugged January 27, 2011, last operated by Stasney Well Service LLC.
The RRC has issued one drilling permit, issued June 18, 2008, 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 6 formation tops, including Dog Bend Ls, Coleman Junction, Sedwick Ls, Stockweather Ls.
Its lease has reported 133K barrels of oil and 48.2K mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 58 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Aug 20, 2009. Resistivity. These are the logs loaded into Petrora from the Railroad Commission's inventories, not necessarily every log run on the well. The RRC holds the files; each opens from its log search for the well. The kind is the RRC's description of the log; the interval is the one filed for it.

"Spans" is by this well's own filed formation tops: a formation runs from its top to the next deeper top filed, and the deepest runs to the bottom of the log. Depths are measured along the wellbore, so on a horizontal the lateral counts in the formation it was landed in.
