CorrelationProperty

Similar…• Most shale basins fall in the Devonian-

Mississippian fairway• Economic shale reservoirs range between

150-450 feet• Devonian-Mississippian shale reservoir

wells average 7000-10,000’• Commercial shale basins generally range

between 0.2 and 1.1 microD• Shale plays are generally gas-focused• Shale plays generally have a single

economic target

Yet so different…• Some of the best shale gas basins are Mesozoic

and lie on the younger side of major thrust belts (Eagle Ford, Haynesville)

• Some of the best shale gas basins have deeper well depths of 10,000-13,000’ (Eagle Ford, Haynesville)

• Increasingly, shale plays are being developed as joint gas/oil assets (Barnett, Eagle Ford)

• Shale plays range from relatively flat with minimal faulting (Haynesville) to highly faulted and structural (Woodford, Marcellus, Eagle Ford) to other features like karst collapse chimneys (Barnett)

• Some shale plays have multiple, adjacent levels economic for development (Bakken)

• Differences in thickness, permeability and porosity drive gas-in-place differences between shale gas plays
