“,Flowback,” is the term for the ,fluid, that floats up to the surface of oil wells that are subjected to hydraulic ,fracturing,. This chemical soup is a mixture of clay, dissolved metal ions, salt and the chemical additives that are used in the fracking process – which most fracking companies keep secret.
