In order to contend with bottom hole conditions (wide range of pressure and temperature), a number of additives are usually used in the OWC slurries, which exhibit different characteristics depending on the combination of admixture used. The objective of this research is to develop a fundamental understanding of the important mechanisms that affect the rheology of OWC slurry incorporating various chemical and mineral admixtures. The partial replacement of OWC using different
