The oil and gas industry is celebrating a milestone on Monday: the birth of hydraulic fracturing, otherwise known as fracking.
The controversial process of pumping water underground to release gas—which has helped grease the resurgence of U.S. energy production—was created 65 years ago, according to a statement by the American Petroleum Institute released on Monday. By all indications, the old girl is aging well: fracking has generated a surge in shale vaulting the U.S. into the upper strata of global oil and gas producers.
To commemorate the occasion, the oil and gas lobby created digital birthday cards featuring the first fracking well in Duncan, Okla. The first fracking patent was issued in 1949, with exclusive rights granted to Halliburton Oil Well Cementing Co., an early incarnation of the oil and defense contracting giant.
