Abstract
A method to determine the velocity of static proppant settling in fracturing fluids. The proppant carrying capability of different friction reducer products can be compared, so the appropriate friction reducer product can be selected for hydraulic fracturing operations. The effect of friction reducer concentrations in the fracturing fluids, the salinity and hardness of the fracturing fluids, and the proppant size on the velocity of static proppant settling can be studied to optimize the chemical structures of the friction reducers in the process of synthesis and optimize the hydraulic fracturing operation, e.g. to determine the proper concentration of friction reducers according to the salinity and proppant size.
