Modular liquidadditivesystems deliver multiple metered amounts of liquidadditivesto thecementslurry for blending. These systems enable a high rate of accuracy with severaladditiveswhich can be metered simultaneously or in sequence. Operators remotely control a stand-alone human machine interface computer, which increases operational safety.

Additionally, specialadditivesare often used to reduce the occurrence of annular gas flow. The cement slurry, commonly formed by mixing Portland cement, water and assorted dry and liquid additives, is pumped into place and allowed to solidify (typically for 12 to 24 hours) before additional drilling activity can resume. The cement usually must reach a strength of 5000 psi [34,474 KPa] before drilling or …

Additivesare chemicals and materials blended into basecementslurries to alter the performance of thecement. Due to the inherent nature of base cements (Neat, Portland and Pozzolanic) and because of the demands placed on thecementsheath throughout the life of the well, the performance properties of the cementing slurry are modified to address the specific and unique conditions of each well.
