Fracturing (aka
Fracturing (aka : Frac or Fracing): A means of stimulating and increasing production from a well by opening new channels in the formation. Fluids and chemicals are pumped into the formation under extremely high pressure, causing cracks to open in the reservoir rock. The fracing fluids also carry sand grains or other materials (propping agents) 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 hold open the formation cracks
