Wellbore servicing compositions and methods of making and using same
Abstract:
A method of servicing a wellbore in a subterranean formation comprising preparing a wellbore servicing fluid comprising a water-soluble crosslinkable composition, a particulate water-swellable superabsorber, and an aqueous base fluid, placing the fluid in a treated portion of the formation, wherein the treated portion comprises a first region having a first region permeability and a second region having a second region permeability, wherein a permeability contrast is a ratio between first region permeability and second region permeability, and wherein the permeability contrast is equal to or greater than 10 prior to placement of the fluid, allowing the superabsorber to occupy at least a portion of the first region, thereby reducing the first region permeability, and allowing the crosslinkable composition to penetrate at least a portion of the second region, thereby reducing the second region permeability, wherein the permeability contrast is reduced to less than 10 after placement of the fluid.
