Abstract:
1. A method of providing at least some degree of fluid loss control during a subterranean treatment, comprising: providing a treatment fluid comprising an aqueous liquid and a fluid loss control additive, the fluid loss control additive comprising a water-soluble polymer having at least one C4 to C22 alkyl hydrophobic modification, wherein the water-soluble polymer comprises a polymer backbone that comprises polar heteroatoms selected from the group consisting of nitrogen, sulfur, and phosphorous, and wherein the water-soluble polymer having at least one C introducing the treatment fluid into a well bore that penetrates a subterranean formation, wherein there is at least a partial reduction in fluid loss into at least a portion of the subterranean formation from at least the treatment fluid or another aqueous fluid introduced into the well bore subsequent to the treatment fluid.
