WELL CEMENTING COMPOSITIONS AND METHODS
A well cementing composition that includes water, portland cement, a retarder and colloidal amorphous silica, present at a concentration between 0.2% and 1.0% by weight of cement. When added at such concentrations, the colloidal amorphous silica behaves as a retarder aid at bottomhole circulating temperatures exceeding 100°C. Methods for employing these compositions in well cementing operations are also disclosed.
