ABSTRACT:
Low and high solids drilling fluids containing high levels (i.e., at least 10,000 ppm) of divalent cations are provided with improved fluid loss control by employing high molecular weight water-in-oil emulsion copolymers of acrylamide and a water soluble salt of acrylic acid. The copolymers, produced by the copolymerization in water-in-oil emulsions form of acrylamide and acrylic acid or the salt thereof in molar ratios of 70:30 to 95:5 are particularly effective in drilling fluids containing high levels of calcium ions.
