The ,flowback, water is considered produced water and must be handled in the same manner as other produced water. Haliburton’s strategic business manager speaking to Bakken Breakout said that water ,flowback, volumes can range between 600,000 to 900,000 gallons (roughly 14,000 to 21,000 barrels) per well. It’s a lot of water to handle and ...

At the end of ,fracturing,, the fracture ,fluid, was broken by a breaker to reduce molecular weight and ,fluid, viscosity. Therefore, the ,fluid, that remains underground may mostly be the gel ,breaking, liquid. Thus, it is important to investigate the influence of gel ,breaking, liquid on the stability of emulsion.
