Middleton-Sachs a Unit #12H
La Salle County · Eagleville (Eagle Ford-1) field · Producing · Horizontal
Middleton-Sachs A Unit #12H (API 42-283-33842) is a horizontal well in La Salle County operated by Verdun Oil EF II LLC, completed December 11, 2013 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued March 18, 2013, permitted to 8,450 ft.
It was permitted by Carrizo (Eagle Ford) LLC and has since transferred to Verdun Oil EF II LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Carrizo, Austin Chalk, Eagle Ford.
Its 2 leases have reported 200K barrels of oil and 1.21M mcf of gas since May 2013, last reporting volume in April 2026. The leases carry 3 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Mar 16, 2016. 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.
