    摘要： A method of servicing a wellbore comprising introducing to the wellbore a wellbore servicing fluid comprising an additive composition comprising a polysaccharide having carboxylate and sulfonate groups. A method of servicing a wellbore comprising preparing at the well site an additive composition comprising a polysaccharide having carboxylate and sulfonate groups, introducing the additive composition into a wellbore servicing fluid, and placing the wellbore servicing fluid into a subterranean formation. A method of preparing a wellbore servicing fluid comprising contacting a polysaccharide composition with an oxidizing agent to form an oxidized polysaccharide, and contacting the oxidized polysaccharide with a sulfonating agent to form a carboxylated sulfonated polysaccharide, and contacting the carboxylated sulfonated polysaccharide with a wellbore servicing fluid.

    摘要： The present invention provides treatment fluids useful for subterranean operations, and more particularly, in at least one aspect, a treatment fluid that comprises a carrier fluid and a cationic surfactant comprising a cationic head group, a polar group attached to the head group, and a hydrophobic group that is either a saturated or unsaturated, branched or straight chain alkyl, and comprises about 6 carbons to about 22 carbons. The treatment fluids of the present invention are at least suitable for use as a remedial treatment for the reduction of existing water blocks, oil blocks, and/or gas condensates.
