ABSTRACT:
A composition is provided which comprises an acrylamide-containing polymer comprising repeat units derived from at least two monomers, a polypropylene glycol, and optionally, a polysaccharide. Also provided is a water-based composition which can be used as drilling fluid wherein the composition comprises calcium chloride, an acrylamide-containing polymer which has repeat units derived from at least two monomers, a polypropylene glycol, and optionally, a polysaccharide. Additionally, a process for using a water-based fluid which has the characteristics of an oil-based fluid as to use in drilling a gumbo shale or highly hydratable formation is provided wherein the process comprises contacting the shale or formation with a composition comprising calcium chloride, an acrylamide-containing polymer, a polypropylene glycol, and optionally, a polysaccharide wherein the acrylamide-containing polymer, polypropylene glycol, and polysaccharide are each present in a sufficient amount to effect the control of fluid loss of a water-based composition.
