The writer acts like getting oil is new, too. I have been working Horizontal Bakken wells pretty steadily since 2000—long before it ever got to be big news—and the natural gas is the byproduct of drilling for oil here, not the other way around.
What has changed over time is the methods of getting out of the ground in a profitable manner. Most people never see it in PA, but there are still a lot or old, I mean old, wells that still produce .. I am not talking about great quantities, but enough to keep pumping. With horizontal drilling (newer) and fracking (not new) it is amazing what can come out of the ground. What is even more amazing is what can come out of new ground ... Stuff that has been cut off from exploration by liberals and echo wackos for decades.
