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 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
