Abstract
A method for mixing cement with water is provided. Dry cement is first slurried in oil. The slurry is easily metered and mixed with water to obtain a cement/water/oil slurry having the desired density. Cement/water/oil slurries thus produced can be used in all applications and have properties, when cured, comparable to cements not containing oil. The method allows precision metering of the cement and therefore precision control over the density of the final cement slurry.
