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.

Claim (Index 26):
A method for injecting a fracturing fluid composition into a subterranean formation, the method comprising:\n preparing a fracturing fluid composition for injection into a subterranean formation, wherein the fracture fluid composition is selected based on rock-fluid interactions stored in a database, wherein the database was generated using:\n rock parameters representative of a rock matrix within the subterranean formation; \n brine parameters being representative of formation brines of the subterranean formation; \n hydrocarbon parameters being representative of hydrocarbons recoverable from the subterranean formation; \n contact angle properties, zeta potential properties, wettability properties, interfacial tension properties, or any combination thereof generated from an interfacial tension test; \n ion selectivity properties generated from an ion selectivity test; \n cation exchange capacity properties generated from a cation exchange capacity test; \n disjoining pressure properties generated from a disjoining pressure test; \n cation exchange and charge compensation properties generated from an adsorption desorption simulation test; \n kinetic and mass transfer properties generated from a forced imbibition test; or \n any combination thereof; and \n injecting the fracturing fluid composition into the subterranean formation to increase production of hydrocarbons from the subterranean formation.
