Geography: Illinois Basin = IL, IN, KY. Marcellus = PA, WV, OH, NY.
Geologic age: Illinois Basin Mississippian (~340 Ma). Marcellus = Middle Devonian (~390 Ma).
Depth: Illinois Basin 1,500-3,000 ft. Marcellus 5,000-9,000 ft.
Hydrocarbon profile: Illinois Basin = predominantly oil. Marcellus = predominantly dry gas.
