Oil & Gas Drilling

Ground Calcium Carbonate UNICARB NRS 1500 is sized and high purity calcium carbonate, is used to increase mud density to about 1.44 kg/m3 and is preferable to barite because it is acid-soluble and can be dissolved with hydrochloric acid to clean up production zones.

Its primary use today is as a bridging agent material in drill-in, completion, and workover fluids. Sized Calcium Carbonate UNICARB NRS1500 particles, along with polymers, control fluid loss in brines or drill-in, completion, and workover fluids. Insoluble calcium carbonate is the precipitated by-product of mud treatments used for removal of either Ca+2 or CO3–2 by addition of the other ion.
