Abstract:
Systems and methods for modifying rheology of a cement slurry are described. Methods may include forming a cement slurry composition and placing the cement slurry composition in a subterranean formation. The cement slurry composition contains water, diutan, and a magnesium oxychloride-based Sorel cement and can have specified properties for a ratio of diutan to water, a thixotropic index value, and a yield point.
