Blok-R750 additive is ground marble that is a high-purity, acid soluble, calcium carbonate used for wellbore strengthening in conventional drilling fluids. Because of its high purity, it is not only used for wellbore strengthening applications but also as a bridging agent to prevent lost circulation in reservoir drill-in fluids and workover/completion fluids. Higher purity also provides better acid solubility.
