Applications of a new, efficient hydraulic fracturing fluid system

This paper discusses low-temperature applications for an optimized low-gel berate fluid system that does not rely on a separate component to maintain system pH. This fluid system's viscosity, fluid loss, static proppant settl ing, and dynamic proppant transport were tested; experimental procedures an d results;are described. Case studies from Argentina, Ecuador, the Texas Pa nhandle, and Permian Basin are also included. A new, borate-crosslinked hydraulic fracturing fluid system has been develo ped. This new, optimized fluid system provides higher viscosity with lower gelling-agent concentrations compared to conventional, borate-crosslinked f luids. Application of the optimized low-gel berate (OLGB) fluid system at l ow temperatures is discussed. Viscosity, proppant transport, and fluid-loss data of the OLGB fluid system are compared to conventional, borate-crossli nked fracturing fluids. Treatment designs are also presented.
