One of the primary functions of a fracturing fluid is to transport and distribute proppant through a fracture and to keep particles suspended till reservoir closes on the fracture. The proppant when suspended and uniformly distributed in a fracture improves productivity of the reservoir. Therefore, a question is frequently asked regarding the minimum fluid viscosity required for satisfactory proppant transport through a fracture. The knowledge is useful for evaluating fluids prior to their use in the stimulation treatment and for demonstrating the effectiveness of new fluid...
