De Witt County · Eagleville (Eagle Ford-2) field · Temp Abandoned · Horizontal
Henderson #1H (API 42-123-32712) is a horizontal well in De Witt County operated by Ensign Natural Resources II LLC, completed June 9, 2012 and listed as temp abandoned on the RRC schedule, shut in October 1, 2021.
The RRC has issued one drilling permit (amended twice), issued February 24, 2012, permitted to 13,351 ft.
It was permitted by Marathon Oil EF LLC and has since transferred to Ensign Natural Resources II LLC on the wellbore schedule.

Its 2 leases have reported 568K barrels of oil and 3.85M mcf of gas since June 2012, last reporting volume in May 2025. The leases carry 11 wells, so these are lease totals, not this well alone.

Well logs
3 logs loaded from the RRC's log index, the latest received Oct 6, 2015. 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.
