The graph above gives some useful perspective to the U.S. shale boom. Sourced from the Energy Information Administration’s Petroleum Supply Monthly, it places the recent uptick in American field production of crude oil and lease condensates in a historical context, and in so doing makes fracking’s feats even more impressive.The shale energy revolution has been unprecedented, both in the speed in which it has transformed our country’s energy outlook and in the overwhelmingly positive impact it’s had on production numbers. Pessimists might point to declining global oil prices as a potential needle to burst this bubble, but producers are already working on ways to tap these unconventional reserves more efficiently. Production is at its highest level since 1986, and we haven’t yet found the limits of shale’s potential. Frack, baby, frack.
