Weighting Materials - Oil & Gas

Barite (ground barium sulphate – BaSO4) in its pure form is chemically inert in fresh water and oil-based drilling fluids. It can be used to increase mud densities to as high as 2400 kg/m³. Barite increases the hydrostatic pressure of the drilling mud allowing it to compensate for high-pressure zones experienced during drilling. The softness of […]

Calcium Carbonate (CaCO3) is a naturally occurring, ground limestone used in Oilfield and Cementing applications. As Cal Carb 0 grind, this finer grade of Calcium Carbonate is used primarily as a weighting material. Cal Carb 0 readily dissolves in the presence of hydrochloric acid. Because of this, it is an ideal weighting agent for use in drilling pressured zones […]

Cal Carb 325 is an acid-soluble calcium carbonate weighting and bridging material used in drilling, completion, and workover fluids. It helps build a filter cake that reduces fluid invasion and assists with loss control, while enabling easier cleanup of the production zone.
