Achieving a high enough injection rate is a major problem in deep wells. Both the bottom hole pressure required to fracture a formation and the pressure loss due to friction increase directly with well depth. This is due to the cumulative effect of the overburden pressure and the length of tubing or casing that the fluid has to travel through to reach the bottom hole. If the injection rate is below a critical value, the proppant may fall out of the frac fluid and cover the perforations forcing the treatment to be stopped.
Friction Reducer is widely used to reduce the frictional pressure loss so that a higher bottom hole pressure and injection rate can be achieved. The drag reduction effect can be as much as 50 to 70% during a fracturing treatment.
