38432 - Viscosity Reduction Of Hydraulic Fracturing Fluids Through Enzymatic Hydrolysis

SPE Journal, 1997

Abstract

High viscosity formulations of guar are used as fracturing fluids to enhance oil and gas production. Following fracturing, these fluids are hydrolyzed and flushed out of the well to provide outflow for oil or gas. Enzymes offer an effective and environmentally benign ...
