Cook #5 (API 42-329-36697) is a well in Midland County operated by Xto Energy Inc., completed August 23, 2011 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued July 2, 2010, permitted to 10,875 ft.
It was permitted by Berry Oil Comp. and has since transferred to Xto Energy Inc. on the wellbore schedule.
Completion filings report 4 formation tops, including Clear Fork, Spraberry, Dean, Wolfcamp.
Its lease has reported 575K barrels of oil and 1.13M mcf of gas since October 2009, last reporting volume in April 2026. The lease carries 10 wells, so these are lease totals, not this well alone.

Well logs
3 logs loaded from the RRC's log index, the latest received May 28, 2014. Density, Neutron, 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.
