Actually, the difference came from horizontal directional drilling.
When that was applied to the tight formation, the difference started. The same wells are hydro frac’d, but that alone would not make the difference.
Who cares whether it’s “HORIZONTAL DRILLING” or hydro fracking or both. It accomplished the problem of having to produce more oil and gas than those Middle Eastern Muslim countries that had us over a barrel. In the past, all they had to do was threaten to cut their oil production, when ever they wanted the western countries to do as they demanded. You remember what they did during the Carter administration, and the long gas lines we had to endure? Now, they can’t do that again. We are producing more oil and gas now than Saudi Arabia. Now, all we have to do is TELL THIS ADMINISTRATION to open up all those GOVERNMENT LANDS for oil and gas drilling.
