Calcium Carbonate has always been in great demand because of its benefits and being valuable filler in countless industries such as Paint, Paper, Powder coating, Plastic & Polymer as well as Rubber. Delcray has always been keen to be capable of matching requirement of any industry, and it offers customized grades as per the requirements of its industrial customers. At present, Calcium Carbonate is manufactured in two different methods, Natural / Ground Calcium Carbonate (GCC) and Surface-Coated Calcium Carbonate.
Calcium carbonate (CaCO3) is an acid soluble, bridging and weighting agent used in drilling, drill‐in and workover/completion fluids. Calcium carbonate is available in three grind sizes: Fine (F), Medium (M), and Coarse (C).
Calcium carbonate is an acid‐soluble bridging and weighting agent for controlling fluid loss and density. It can be used in fluids ranging from conventional oil‐base and water‐base drilling fluids. As a bridging agent and fluid loss additive, normal concentrations are in the 10 to 50 lb/bbl (29 to 143 kg/m3) range. Calcium carbonate F (fine) is used as the standard weighting material. Calcium carbonate M (medium) and calcium carbonate C (coarse) are used for bridging and seepage control or can be used as a weight material with a larger particle size.
