  • Enhanced friction reducers for water-based fracturing fluids
    Patent number: 11479715
    Abstract: A fracturing fluid can include: a base fluid, wherein the base fluid comprises water; proppant; a friction reducer; and a friction reducer enhancer, wherein the friction reducer enhancer is a surfactant. The friction reducer enhancer can be in a concentration greater than or equal to a critical micelle concentration. Methods of fracturing a subterranean formation can include introducing the fracturing fluid into the subterranean formation. The friction reducer enhancer can increase the hydration rate of the friction reducer, whereby friction reduction of the fracturing fluid can occur much faster than without the friction reducer enhancer.
    Type: Grant
