Ohio has gotten most of the attention regarding tapping the Utica shale. But the Utica shale is much, much larger and extends well into Pennsylvania, New York and other states. Much of the Utica is underneath the well-publicized Marcellus shale, reports RealClearEnergy.
RealClearEnergy: "To date most of the attention has been focused on development of the Marcellus Shale in Pennsylvania while exploration of the Utica Shale has been limited to Ohio.
