Marcellus (Appalachian Basin)

The Marcellus play is one of the smallest oil producers in the United States. This play only offers about 50,000 barrels of oil per day. On the other hand, it is one of the largest natural gas producers in the country. Drilling in Marcellus produces about 13 billion cubic feet of natural gas per day. This is because the majority of the drilling sites focus on the natural gas that is prevalent in the area. In fact, eight of ten drill spots on this play are focused on getting the natural gas.
