About 20 years ago, an entrepreneur named George Mitchell proved that it was possible to get lots of oil and gas out of parts of the earth long thought to be sucked dry, by injecting liquid at high pressure into a horizontal well below the surface. About 10 years ago, fracking — the common term for this process — began in earnest.
In that short amount of time, fracking in America has turned the energy world upside down. A decade and a half ago, Congress was hand-wringing about impending shortages of oil and natural gas. By the end of 2015, President Barack Obama lifted the ban against oil exports. Today, America is the world’s largest producer of natural gas and is an oil powerhouse, ready to eclipse both Saudi Arabia and Russia.
