Patent abstract
A fluid loss control pill or solution includes a polymer having a functional group that can be hydrolyzed by a base or a nucleophile. A method for fluid loss control in a subterranean formation includes placing a fluid loss control pill or solution in a wellbore penetrating the subterranean formation, wherein the fluid loss control pill or solution comprises a polymer having a functional group that can be hydrolyzed by a base or a nucleophile; and converting the polymer into a soluble form by hydrolyzing the functional group with a base or a nucleophile, when fluid loss control is no longer needed.
