Ouch! certainly not good news for oil countries members of OPEC and more for those who only depend economically on the marketing of oil, as is the case of Venezuela ...
The fracking that is based on the injection under pressure of some material in the ground, usually water, with the aim of expanding the existing fractures in the rocky substratum that encloses the gas or oil, thus favoring its exit towards the exterior; for the United States it has turned out to be a great exploitation technique that has allowed it to reduce the importation of gas or oil, and even to be able to think of total self-sufficiency. And of course, with a cheaper energy cost companies will be more competitive.
Definitely will continue to be a hard blow to OPEC.
