Calcium Carbonate is a weighting agent and acid-soluble bridging material with high purity which can increase the mud density and control fluid loss in drilling fluid systems. Our calcium carbonate products include a wide variety of particle sizes ranging from 325 mesh (35 µ) to 30 mesh (550 µ). 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 calcium carbonate powder manufacturers and suppliers for weighting agents in oil well drilling. We supply high quality ground calcium carbonate powder for sale in oilfield industry. Where to buy calcium carbonate powder like Baracarb, contact us!
♦Natural weighting material and easily degradable
♦Be acid-soluble and minimize formation damage
♦Effective bridging agent, inert and insoluble, less effect on fluid properties
♦Fine and medium grades can pass through most fine-mesh shale shaker screens

Package and Storage
Package: 25kg lined plastic woven bag and jumbo bags or packed according to the clients' requirements. Store in dry cool and ventilation environment. Ensure that packaging is completely sealed. Avoid moisture and damp.
Shelf time: two years
Recommended Dosage
Calcium Carbonate is added to the mud system through the hopper. The amount of CalCium Carbonate required to increase the mud density can be calculated with the following formulas:
  CalCium Carbonate, lb/bbl = (980 (w2–w1))/ (23.3–w2)
   w1= Initial mud weight in lb/gal
   w2= Desired mud weight in lb/gal
  CalCium Carbonate, kg/m3= (2,800 (w2–w1))/(2.8–w2)
   w1= Initial mud weight in specific gravity
   w2= Desired mud weight in specific gravity
Used in water-base drilling fluid and well completion fluid as acid soluble bridge blocking additive and inert fluid loss additive
Normal concentration: 40-150 kg/m3 as a bridging agent and fluid loss additive.
