Contour Maps Showing Depth and Thickness of Eagle Ford Shale
The Eagle Ford shale lies at different depths across South Texas. The northern part of the Eagle Ford shale is becoming known as the “oil window” since it is mostly low pressure and liquid rich. The central part of the play has been called the “condensate and gas window”, with higher pore pressures and more gas but still significant amounts of free liquids. Farther south in the more thermally mature deep Eagle Ford shale, high pressure dry gas is the general rule. The following map of Eagle Ford depth contour lines shows the shale anywhere from 2000 feet deep in southern Bexar County,to over 13,000′ farther south. Farther down the page is a map showing depths of the Eagle Ford shale to 17,000′ +. Maps of Eagle Ford shale depth below from Petrohawk Energy
Second map of Eagle Ford shale depths.
Shows the depth of the Eagle Ford shale in southern Gonzales county at over 13,000′. Both maps are from Petrohawk Energy. In southern LaSalle county, in the dry gas window of the Eagle Ford shale, depths reach up to 15,000′.
The map below shows the thickness of the Eagle Ford shale in several key counties.
