    Durability and Rheological Evaluation of Cement Slurries

    Class G oil well cement is used as a basic well cement and, mixed with additives, to covers a wide range of well depths and temperatures (Vidick and Schlumberger, 1990). Silica fumes use as a cement slurry additive to reduce the density of cement and increase slurry performance and control hydrostatic pressure during drilling cementing.

    On the Rheological Parameters Governing Oilwell Cement Slurry Stability

    Rheology plays important roles on slurry design: • In assuring that the cement slurry can be mixed at the surface and can be pumped into the well with minimum pressure drop. • In governing the flow regime for optimum cement slurry placement. • In maintaining the solid particles in suspension during the fluid state of the cement slurry.
