What is fracking? | oilandgasinfo.ca

After fracking, natural gas or oil flows to the wellbore and then to the surface wellhead, bringing with it frac ,fluid, that was pumped along with natural occurring fluids that are present in the target rock formation. This ,flowback fluid, is separated from the gas and oil at the surface, and contained temporarily in tanks or lined ponds onsite.
