EXCO Resources was once a sizable player in the Marcellus. They still have 145,000 net acres in the Marcellus, with 124 horizontal Marcellus wells drilled and in production. However, EXCO, as we pointed out in March, has pretty much abandoned the Marcellus at this point (see EXCO: No Marcellus Drilling in 2015/2016, NYSE Threatens Delisting).
