Chesapeake, Cabot, Epsilon Energy, etc. are drilling both the Upper Marcellus and Lower Marcellus in NE PA.
The well-cross sections on the DEP plats are not detailed enough for my project... does anyone have another source I can take a look at? or a list of the wells that are targeting the Upper Marcellus?
I do not know if knowing the vertical depth would give that Upper/Lower information, but the vertical depths of virtually all unconventional wells can be had on the Fracfocus site.
While I usually punch in the API #, other well identifiers can be used.
