Lost Circulation Material
Product Description
Calcium Carbonate (CaCO3) is a high-purity ground limestone, used to increase the density of drilling and workover fluids, to reduce fluid loss and as a lost circulation material.
Application/Function
Used as a weighting agent, a bridging agent to reduce filtration loss (for F, M or C)
Used as a lost-circulation material in both water-based and nonaqueous drilling fluids (for F, M or C)
Current uses include wellbore strengthening
Advantages
Environmentally benign
Compatible with formate systems, as well as general water and nonaqueous fluids
Resists attrition
