La Salle County · Eagleville (Eagle Ford-1) field · Producing · Horizontal
Ledwig East Unit I Las #E 4H (API 42-283-35803) is a horizontal well in La Salle County operated by Ineos USA Oil & Gas LLC, completed February 16, 2017 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued August 11, 2016, permitted to 8,107 ft.
It was permitted by Chesapeake Operating, L.L.C. and has since transferred to Ineos USA Oil & Gas LLC on the wellbore schedule.
Completion filings report 10 formation tops, including Yegua, Queen City, Sparta, Wilcox.
Its lease has reported 866K barrels of oil and 964K mcf of gas since December 2012, last reporting volume in April 2026. The lease carries 4 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, 1 of it with a digital LAS file, the latest received Nov 27, 2019. Gamma ray. 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.
