CEMENT SYSTEMS AND ADDITIVES Achieve reliable zonal isolation and enhanced performance . The wide selection of Halliburton chemicals and additives enables any slurry to be customized for the demands of each well.
· In addition, more than 100 cement additives are available to adjust cement performance, allowing engineers to customize a cement formulation for a particular well environment. The principal objective is to formulate a cement that is pumpable for a time sufficient for placement in the annulus, develops strength within a few hours after placement and remains durable throughout the well's lifetime.
· Amphoteric additives, among them amidobetaines, are socalled cosurfactants that support the airentraining of concrete and also stabilize the durability of air bubbles. The invention of concrete in antiquity created many new possibilities for architecture, thanks to which buildings such as the Pantheon and the Coliseum were created and have survived to this day.
