Abstract

gas reservoir stimulation.Surfactant micellar fluids structured very low-molecular-weight surfactants into elongated micelles have been used as stimulation fluids trying to remove the drawback of polymer fluids. The viscoelastic behavior of these surfactant micellar fluids is believed to be rooted in the overlap and entanglement of elongated micelles which yields both the viscous and elastic characteristics to the fluid.High fluid leak-off and difficult cleanup associated with traditional surfactant micellar fluidshave, however, limited their utilityintight gas stimulation applications. Our recent work has shown that the addition of carefully selected inorganic nano-crystals - less than 100 nanometers in size – to the new surfactant micellar fluid formulation can overcome the above limitation without negatively effecting the internal breaking mechanisms.Our recent results highlight the mechanism of fluid loss control and easy cleanup of this nanoparticle reinforced surfactant micellar fluid system for tight gas stimulation applications.
