It was permitted by Fiml Natural Resources, LLC and has since transferred to Discovery Natural Resources LLC on the wellbore schedule.

Its 2 leases have reported 3.59M barrels of oil and 42.1M mcf of gas since September 2011, last reporting volume in April 2026. The leases carry 71 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Dec 23, 2014. Density, 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.
