Marcellus Shale - Appalachian Basin Natural Gas Play
A resource that moved from "marginal" to "spectacular" as a result of new drilling technology.
Super Giant Gas Field in the Appalachians?
Twenty years ago every geologist involved in Appalachian Basin oil and gas knew about the Devonian black shale called the Marcellus. Its black color made it easy to spot in the field and its slightly radioactive signature made it a very easy pick on a geophysical well log.
However, very few of these geologists were excited about the Marcellus Shale as a major source of natural gas. Wells drilled through it produced some gas but rarely in commercial amounts. Few if any in the natural gas industry suspected that the Marcellus might soon be a major contributor to the natural gas supply of the United States - large enough to be spoken of as a "super giant" gas field.
