Cementing Chemicals

In well cementing, Cement additives selected for cementing operations are an integral part of sound well design, construction and well integrity.
Additives are available to enhance the properties of oil well slurries and achieve successful placement between the casing and the geological formation,
rapid compressive strength development and adequate zonal isolation during the lifetime of the well.

Additives are commonly added to cement formulations to;

  • Disperse cement particles,
  • Modify the setting time under temperature and pressure conditions in the well,
  • Control filtration losses of the liquid from the cement slurry during and after placement,
  • Compensate for shrinkage of the cement as it sets and hardens, Improve interfacial bonding between cement and casing,
  • control influx and migration of formation fluids into the cement column during setting.

There are different types of cement additives that have been developed to allow the use of cement in many different oil and gas well applications.
Each type has different types of additives that have been developed to perform almost the same function during cement slurry design.
However, there are some additives under each major type that are commonly used in cement slurry design for oil and gas well cementing operations.
