Claim Text:
1. A method comprising: providing a treatment fluid comprising an aqueous base fluid, a hydrophobically modified flocculating water-soluble polymer, a corrosion inhibitor present in the treatment fluid in an amount in the range of about 0.1% to about 3% by volume of the treatment fluid, and separate supplemental polymers present in the treatment fluid in an amount in the range of about 0.5% to about 5% by weight of the treatment fluid, wherein the separate supplemental polymers are a combination of a non-hydrophobically modified flocculating polymer of a poly(diallyldimethylammonium chloride) and a relative permeability modifier polymer; introducing the treatment fluid into a wellbore in a subterranean formation having unconsolidated particulates therein; flocculating at least a portion of the unconsolidated particulates by exposure to the hydrophobically modified flocculating water-soluble polymer; removing the treatment fluid comprising the flocculated unconsolidated particulates from the wellbore in the subterranean formation.
