## Answer
Quick answer The Illinois Basin and Marcellus Shale are both major U.S. mineral-producing regions but differ on nearly every dimension. Illinois Basin is Mississippian-age conventional waterflood production at 1,500-3,000 feet across IL/IN/KY, predominantly oil, operated by small independents. Marcellus is Devonian-age unconventional horizontal shale production at 5,000-9,000 feet across PA/WV/OH/NY, predominantly dry gas, operated by large public producers (EQT, Range, CNX, Coterra, Antero).
