    Cal Carb 325

    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 completion and work over fluids where the cleanup of the production zone is critical to well productivity.

    • Prevent fluid invasion of permeable zones
    • Prevent loss of circulation during drilling, workover and completion activities
