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 optimal weighting agent for drilling in pressured zones and for completion and workover fluids, ensuring easy cleanup of the production zone to enhance well productivity. Its ability to dissolve in hydrochloric acid effectively prevents fluid invasion and loss of circulation during drilling, workover, and completion activities.
