It was permitted by Cog Operating LLC and has since transferred to Diamondback E&P LLC on the wellbore schedule.

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

1 log loaded from the RRC's log index, the latest received Jan 27, 2015. 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.
