Agents

Cementing agents are used to obtain specific results in the performance of the cement.  This can include affecting cement during placement as well as throughout the life of the well.  Specific agents help facilitate the integrity of the hydraulic seal of cement to the formation and to the casing in specific conditions.  Another type of agent can decrease or increase the density of the cement as determined by the lb/gal weight.  Yet another type of agent can be used to enhance the consistency of solids suspended throughout the slurry and help prevent settling during cement hydration.

Optimizing cement slurries with agents is best done by considering field-proven technical solutions, laboratory-driven empirical data derived from testing of specific blends, and finite element analysis models such as that provided by Halliburton’s iCemSM Services, the industry’s most robust engineering design tool for assessing and monitoring specific slurry design variables before, during, and after a cement job.
