Abstract

A method and composition is provided for a relative permeability modifying polymer for use with drilling fluids that comprises a water soluble polymer formed from a hydrophobic or hydrophobically modified hydrophilic monomer and a hydrophilic monomer. In an alternative embodiment, a method is provided for producing a water soluble polymer formed from a hydrophilic monomer for use as a relative permeability modifying polymer.
