Abstract
Fracturing methods include introducing a relatively high concentration of a surfactant in an initial portion of one or more fluids used in a fracturing treatment and then cutting or ramping back to a relatively low concentration of the surfactant in the remaining fluid used in the treatment. By using such a method, the volume of surfactant to provide superior treatment can be reduced significantly from the normal recommendations, leading to a high cost savings while still obtaining the desired effect upon cleanup.
