Shackelford County · Cook Ranch (Strawn Sand) field · Producing · Vertical
Cook Strawn 85s/86s Pooled Unit #64 (API 42-417-39040) is a well in Shackelford County operated by Stasney Well Service LLC, completed May 17, 2010 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued December 15, 2009, permitted to 3,290 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 Coleman Junction, Dothan Ls, Tannehill, Crystal Falls Ls.
Its lease has reported 66.5K barrels of oil and 67.1K mcf of gas since May 2010, with no volume in the three years through April 2026. The lease carries 12 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 23, 2010. 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.
