CEMENT ADDITIVES AND SPECIALTY PRODUCTS

The most important function of oil & gas well primary cementing is to isolate the various zones within the wellbore. In others words, the cement must prevent fluids or gases in one particular zone from mingling with those of another. A properly designed and placed cement slurry accomplishes this by creating the necessary seal between the casing and the formation. The cement must prevent migration or fluid channeling throughout the cement.

Today's well cement systems must perform in a variety of down hole conditions, from 0 °C - over 350 °C., and at bottom hole pressures in excess of 30,000 psi. Messina has developed a complete line of cement additives, which modify the characteristics and performance of the cement slurry. This means that a slurry can be designed to function over the wide range of conditions that occur in the wellbore.
