The Appalachian Basin features an enormous stacked pay play with geologic targets ranging from the Marcellus and Utica shales through upper Devonian formations. The region’s traditional industrial base and proximity to large urban markets creates a bright future for hydrocarbon production in the Northeast. Penn State geology professor Terry Engelder and DrillingInfo’s Allen Gilmer outline the vast hydrocarbon potential in the Appalachian Basin and shed insights on what makes the region unique.
