LA Salle County · Eagleville (Eagle Ford-1) field · Producing · Horizontal
Zcw Unit C #3H (API 42-283-36366) is a horizontal well in La Salle County operated by Crescent Energy Operating LLC, completed May 5, 2021 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued December 31, 2018, permitted to 8,800 ft.
It was permitted by Cheyenne Petroleum Company and has since transferred to Crescent Energy Operating LLC on the wellbore schedule.
Completion filings report 10 formation tops, including Sparta, Queen City, Wilcox, Escondido.
Its lease has reported 414K barrels of oil and 441K mcf of gas since July 2014, last reporting in July 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
