The Barnett Shale is an upper Mississippian aged organic rich shale.  It serves as the reservoir, source and seal for the Newark East field.  It is also the primary source for petroleum in the Fort Worth Basin, and has been the source rock  of oil and gas for other conventional reservoir systems in the basin such as the Ellenburger, Strawn, and others.  Jarvie Et Al, 2007, Montgomery,<ref>Montgomery, S.
