Pena-Butts Unit #1H
La Salle County · Eagleville (Eagle Ford-1) field · Producing · Horizontal
Pena-Butts Unit #1H (API 42-283-33057) is a horizontal well in La Salle County operated by Verdun Oil EF II LLC, completed April 2, 2012 and listed as producing on the RRC schedule, shut in April 1, 2024.
The RRC has issued one drilling permit, issued February 18, 2012, permitted to 9,627 ft.
It was permitted by Eog Resources, Inc. and has since transferred to Verdun Oil EF II LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Anacacho, Austin Chalk, Eagle Ford.
Its 2 leases have reported 90.7K barrels of oil and 198K mcf of gas since April 2012, last reporting volume in December 2023. The leases carry 2 wells, so these are lease totals, not this well alone.

"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.
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.
