Eagle Ford Formation
The Eagle Ford Shale is a major tight oil and condensate play stretching across South Texas, producing both oil and associated natural gas. The formation's oil, condensate, and gas windows offer diverse drilling targets.
Formation Type
Tight Oil/Condensate
Depth Range
4,000–14,000 ft
Basin(s)
Eagle Ford
States
TX
Geology & Formation Overview
The Eagle Ford is an Upper Cretaceous calcareous shale and marl deposited along a carbonate ramp. It transitions from a dry gas window in the northeast to a condensate window in the center and an oil window in the southwest. The formation dips to the southwest, increasing depth and temperature — shifting production from oil to gas.
