Abstract:
A polyacrylamide friction reducer wherein the friction reducer contains surfactant functional groups, and wherein the polyacrylamide friction reducer is degradable, can be used for multi-functional, slickwater fracturing fluid projects. Under downhole conditions, the polymer degrades and releases the surfactant molecules to act as oil displacing agent to provide additional stimulation.
