Cement slurries are designed to lower the heat of hydration while meeting or exceeding the other properties needed for successful deepwater cementing. Heat of hydration is reduced by a factor of more than two when compared to the conventional cement-slurry design. The improved cement-slurry designs lower considerably the thermal conductivity of the set cement sheath.

Laboratory tests designed to measure and optimize the heat of hydration are discussed and field implementation of these slurries and results are presented. Results presented in this paper should help the industry construct and produce wells without destabilizing the hydrates, thus, promoting well safety and economics.

We may provide customer with the cement slurry design and validate the formulation of slurry via test.
