摘要:
Methods comprising providing a carrier fluid comprising an aqueous-based component, a water-soluble relative permeability modifier, and gravel particulates wherein the water-soluble relative permeability modifier suspends at least a portion of the gravel particulates; and introducing the carrier fluid into a well bore penetrating a subterranean formation, such that the gravel particulates form a gravel pack near the well bore. In some embodiments, the carrier fluid is substantially free of a viscosifying agent.
