What is hydraulic (FRACKING) fracturing?
The Photo shows a Standard Fracking operation. The frac spread Equipment is used for Formation fracturing, with fluids – mostly water and sand, with a small percentage of chemical additives. From the blender unit then to the Pressure Pumping units, water and sand is injected down the well bore into the formation. The fluid, pumped under pressure, thousands of pounds per square inch, causes the rock to fracture along weak areas.
Hydraulic fracturing creates small cracks, or (FRACKING) fractures, in deep, underground geological formations to liberate oil or natural gas. The fluids that create the initial fractures is then mixed with thicker fluids that include sand and gelatin. These more compressed fluids lengthen the openings in the rock. When the fractures are complete, and pressure is relieved, the fluids flow back up the well where they are captured and stored for later treatment or disposal.
As the fluids flow back up, frac sand remains in the fractures and props the rock open.
