There is no current production in North Carolina, to my knowledge. Their best bet would be coalbed methane or offshore where some wells found some non-commercial shows back the 1970-1980’s. There have only been 129 wells drilled in the entire state. That is less than a three-mile radius of where I am sitting in my office in Texas. Only seven wells have been drilled in NC since 1980. Next, Maine will ban fracing and then override it for show.

It's Triassic Basin, if that means anything to you geologically. All I know is the Triassic had dinosaurs. And cavemen!
