CALCIUM CARBONATE (FINE)
DescriptionCalcium carbonate ( CaCO3 ) is an acid soluable, bridging and weighting agent for drilling, work over and completion fluids. DDC Calcium Carbonate is available in three recomended grades. Fine , Medium and Coarse . Fine is used as a weighting material for drilling and work over fluids . Medium and Coarse grades are generally used for bridging or can be used for a weighting material with a larger particle size.
