Really? Controversial?
A dead give away to a liberal writer. It is nothing more than commonsense and a practice that has been in use for decades. I suppose the writer doesn't call EPA regulations or anything Obama does "controversial".
Controversial. You know, like the controversial process of exhaling Carbon Dioxide which will lead to Global Warming.
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.
