As operators continued to explore for the Middle Devonian, Marcellus Shale throughout western and northern Pennsylvania, shallower Upper Devonian shales were looked at with a whole new set of tools and with a different perspective. Are the shallower Upper Devonian shales perspective unconventional shale reservoirs?
The shallower than the Marcellus Shale black shales include the Geneseo/Burket Shale, Middlesex shale, Rhinestreet Shale and Dunkirk Shale. All are currently being produced to some extent in Pennsylvania and West Virginia. What, if any, are the implications for these shallower than Marcellus Shale reservoirs in western New York?
