High solids pumpable cement additives


Jardine, L. A., Myers, D., & Ranganathan, A. (2004). IPC No. U.S.High solids pumpable cement additives (Patent No. 6800129.)


Exemplary liquid cement additive compositions have high solids loading which includes alkali or alkaline earth metal salts and other cement additive components. The liquid carrier is preferably aqueous in nature, although non-aqueous carriers are possible, and the carrier is modified using a viscosity modifying agent and dispersant to help load salt and other solids in high level amounts. Thus, methods for making the liquid cement additive compositions are also disclosed.
