Tight-oil production in the US set new records in 2019, but the banner year ended with an important caveat: more than two-thirds of crude production from shale plays flowed from wells drilled in the past 2 years.

Hydraulic Fracturing or “Fracking” has been in common use in the oil and gas industry since 1947. Basic questions about fracking are discussed, what it is, how it works; misperceptions and myths about fracking are debunked.[cont'd]
