Calcium Carbone

Calcium carbonate, or CaCO3, comprises more than 4% of the earth’s crust and is found throughout the world. Its most common natural forms are chalk, limestone, and marble, produced by the sedimentation of the shells of small fossilized snails, shellfish, and coral over millions of years. Although all three forms are identical in chemical terms, they differ in many other respects, including purity, whiteness, Particle Size, Thermal Conductivity, Solubility, Alkalinity and homogeneity. 

Calcium Carbonate is one the most useful mineral which known by man and uses in expanded fields like water-based drilling or even in medicines and uses for many industries specially in drilling as primary substance of drilling mud, limestone or in color making as filler.

Paint industry, PVC and Plastic industry, construction chemicals, adhesives, rubber industry. Etc are the main customers for our Calcium Carbonate products. Particle size  ranging from 7 microns and up to 75 microns

Calcium Carbonate in Drilling
it is used as a bridging agent and/or weighting material in oil base and water base drilling fluids, work over fluids, and completion fluids. It comes in a wide variety of particle sizes ranging from 325 mesh (35 µ) to 30 mesh (550 µ). Custom sizing for particular applications is also available. It is used to prevent fluid invasion of permeable zones, and to prevent loss of circulation during drilling, workover, and completion activities.

Particle Size. 

  • Calcium Carbone                          = D50 : 1-8          Micron

  • Calcium Carbone Extra Fine       = D50 : 10-30      Micron

  • Calcium Carbone F (fine)            = D50 : 40-60      Micron

  • Calcium Carbone M (medium)  = D50 : 130-170  Micron

  • Calcium Carbone C (coarse)      = D50 : 250-350   Micron

  • Calcium Carbonate                     = D50 : 450-550   Micron

  • In addition to the above standard grades we also Supply special grades (2-2500 Micron) as per customers requirement to meet their own specifications.
