The principal objective of well cementing operations 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. Using NRG-RETARDER LR for low and moderate circulating temperatures up to 176°F (80°C), allows to extend the time during which a cement slurry is pumpable.
