Under extreme high hydraulic pressure, frac fluids (such as distillate, diesel fuel, crude oil, dilute hydrochloric acid, water, or kerosene) are pumped down through production tubing or drill pipe and forced out below a packer or in between two packers. The pressure causes cracks to open in the formation and the fluid penetrates the formation through the cracks. Sand grains, aluminum pellets, walnut shells, or similar materials (propping agents) are carried in suspension by the fluid into the cracks. When the pressure is released at the surface, the fracturing fluid returns to the well but leaves behind the propping agents to keep the formation cracks open. The fluid used for penetration of the frac must be clean and can not contain sand or other organics that may be harmfull for the process or the environment. The used frac fluid also have to be cleaned.
Twin Filter offeres several solutions for the filtration of Frac Fluids.
