----- Section 5-Wastewater Characterization and Management In wells that are hydraulically fractured, fracturing fluid - typically consisting of water, a number of chemical additives and a proppant (such as sand) - is pumped down the well bore under pressure to create and hold open fractures in the target formation that allow for the flow of oil and gas. Some fracturing fluid, as well as water from the …

Hydraulic ,fracturing, of multi-lateral horizontal wells for shale gas prodn. usually requires a great amt. of water. Field data indicate that only a small fraction of the injected water can be recovered during the clean-up phase. Esp., when shale oil and gas wells undergo month-long shut-in periods after multi-stage ,fracturing, processes.

Fluids, from blowdown piping and or discharge lines are usually pumped to a knock-out drum separator, where vapor, oil-water ,separation, and recovery take place. After separating the entrained liquid from the vapor, the stream is fed to the flare unit, where it automatically ignites and burns in the atmosphere.

After the hydraulic fracturing procedure is completed and pressure is released, the direction of fluid flow reverses, and a portion of the water and excess proppant flow back through the wellbore to the surface, referred to as "flowback." Water may also continue to flow to the surface—along with the natural gas—for the life of the well.
