Not one formation; the well must be completed in one of them, and no target formation is stated.

Cook #8 (API 42-329-36713) is a well in Midland County operated by Xto Energy Inc., completed October 22, 2011 and listed as shut in on the RRC schedule, shut in April 1, 2025.

The RRC has issued one drilling permit (amended twice), issued August 10, 2010, permitted to 10,852 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.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.

Well logs

2 logs loaded from the RRC's log index, the latest received May 5, 2014. Cased hole, Neutron. 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.
