In the article above it states:
In a gas shale such as the Marcellus shale, the host rock constitutes both the hydrocarbon source and reservoir, with either natural or man-made fractures needed to induce the gas to flow from the rock. That, then, raises a question regarding the feasibility of producing gas from the Marcellus shale. Engelder and Lash have presented evidence for fracturing in the shale that could provide a key to successful gas production.
Yeah I read that. I was refering to the end of the article where it discusses Range Resources Corp decision to frac their wells. If their problem was simply perforating the wrong zones (intact rock between fractures) then it is an easy fix.
