The present invention provides a method of cementing in a subterranean
formation that includes providing a cement composition that includes
water, cement, and a fluid loss control additive that includes a
water-soluble hydrophobically modified polymer or a hydrophilically
modified water-soluble polymer; placing the cement composition into the
subterranean formation; and allowing the cement composition to set
therein. In certain embodiments, the water-soluble hydrophobically
modified polymer or the hydrophilically modified water-soluble polymer
may include a polymer backbone that comprises polar heteroatoms. In
another embodiment, the water-soluble hydrophobically modified polymer
may be a reaction product of a hydrophobic compound with a
polyvinylamine, a poly(vinylamine/vinyl alcohol), or an alkyl acrylate
polymer.
