Weighting Materials - Geotechnical & Environmental

Barite is a weighting material possessing a specific gravity ranging from 4.2 to 4.3  It is used in all muds to increase the density or weight. Mud weights up to about 20 ppg can be obtained without incurring strains on pump equipment. 

Calcium Carbonate (CaCO3) is a naturally occurring, ground limestone. As Cal Carb 325 grinds, this finer grade of Calcium Carbonate is used primarily as a weighting material. Calcium Carbonate readily dissolves in the presence of hydrochloric acid. Because of this, Cal Carb 325 is an ideal weighting agent for use in drilling pressured zones or in …
