cement slurry produced

free water

The aqueous phase that separates from a slurry or mixture of fluids In cementing operations free water is undesirable since channels tend to form through the set cement providing potential gas migration paths When processing reservoir fluids the water that separates easily under gravity separation is known as free water In some cases additional water may be locked in an emulsion

Slurry Densities

14 ensp 0183 ensp Slurry concentration by weight can be measured by evaporating a known weight of slurry and measure the weight of dried solids Example Calculating Slurry Density The density of a slurry where the density of the solids is 2500 kg m 3 the density of the liquid is 1000 kg m 3
