Abstract
A system and method for matrix stimulation field monitoring providing real time control, optimization and post job evaluation of matrix treatments is disclosed herein. Using calculated or measured bottom hole pressures or coil tubing reflective pressures, the system and method predicts pre-treatment damage or skin from a step rate test, then shows the evolution of skin removal versus treating fluid volume in real time. The method and system provides real time information about diverter use, treatment height, damage radius and other important well parameters.
