Abstract: A workflow to optimize a fracturing fluid for injection into a subterranean formation is provided. The workflow comprises measurement of fundamental properties and characteristics of reservoir rock and fluid, their interaction with fracturing fluid, computer-based models and laboratory performance testing to select preferred fracturing base fluid and additives package for use in fracturing/re-fracturing stimulation of specific shale formations to enhance hydrocarbon recovery.
