LA Salle County · Eagleville (Eagle Ford-1) field · Producing · Horizontal
Stephenson Unit I Las #B 3H (API 42-283-36820) is a horizontal well in La Salle County operated by Ineos USA Oil & Gas LLC, completed October 14, 2019 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued July 18, 2019, permitted to 9,000 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 590K barrels of oil and 450K mcf of gas since January 2014, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
