Calcium Carbonate (also carbonate de calcium) is an acid-soluble bridging and weighting agent with high purity which can control fluid loss and density in mud systems ranging from conventional water-based and oil-based drilling fluids to drill-in, completion and workover fluids. Calcium carbonate is available in fine, medium and coarse grades. Calcium carbonate fine grade is used as a standard weighting material. Calcium carbonate medium and coarse grades can be used for bridging and seepage control or can be used as a weighting material with a larger particle size.Bichan is one of reliable CaCO3 calcium carbonate powder manufacturers and suppliers for oilfield bridge blocking additive and inert lost circulation material.
