    Silica Flour

    Silica Flour is powdered sand that inhibits strength retrogression in oil-well cements at elevated temperatures. As a cement extender, it prevents cement sedimentation by increasing low shear viscosity.

    Silica Flour adjusts the phase transformation of cement-water mixture that occurs at high temperature which helps oil-well cement maintain its compressive strength and low permeability.

    Silica Flour has been widely used in cementing SAGD wells in combination with refractory-type cements. It is compatible with all cements as well as commonly used additives such as retarders, friction reducers, fluid loss additives, weighting and lost-circulation materials.
