In the last few days I've seen several folks reference the "Volatile Oil Window" for the Utica.  I thought I've been pretty well-informed about this play, but the "excitement" I've recently seen referenced to the Volatile Window is fairly news to me.  Can people in the know please share their resources/sources that discuss why this is an exciting part of the play to O&G companies?  I get why it is exciting, but haven't seen many references from the O&Gs to this portion of the play.  It doesn't even seem to be getting much activity right now.  I see lots of trumpets blowing about the "core" in Noble, Harrison, Guernsey, etc. but to me that's the NGL/wet gas region.  What am I missing?
