: liquid used in fracking that returns to the surface after being injected into shale The drillers then shoot millions of gallons of highly pressurized water, mixed with sand and small amounts of additives known as fracking chemicals, down the well, widening the shale fractures. Natural pressure forces the liquids back up the well, producing what's known as flowback, and the gas rushes from the fractures into the pipe.— Bryan Walsh Methane within the shale diffuses into these fissures and flows up the well.
