Abstract:
1. A well treatment composition for use in a cement composition comprising: an aqueous liquid; a fluid loss additive, wherein the fluid loss additive comprises a high molecular weight, water-swellable polymer, wherein the polymer for the fluid loss additive comprises: cellulose; guar; xanthan; starch; a monomer or monomers selected from the group consisting of acrylamido-methyl-propane sulfonate (AMPS), N-vinyl-N-methylaceamide, N-vinylformamide, N-vinylpyrrolidone, acrylonitrile, acrylamide, acrylomorpholine, vinyl alcohol, maleic anhydride, acrylic acid, methacrylic acid; and any combination thereof; and an amphiphilic dispersant, wherein the dispersant is a non-ionic surfactant, and wherein the surfactant has the following chemical formula: wherein the well treatment composition has an activity of at least 10%, wherein the well treatment composition does not include cement, wherein the fluid loss additive is in a concentration of about 20% to about 50% by weight of the treatment composition, and wherein the non-ionic surfactant is in a concentration of about 5% to about 50% by weight of the treatment composition.
