  • Calcium Carbonate (Lime Stone Powder) F/M/C

PRODUCT DETAILS

DESCRIPTION :

Calcium Carbonate (Fine / Medium / Coarse) is a high-purity limestone-based bridging and weighting material used in drilling, completion, and workover fluids. It is acid-soluble, making it ideal for minimizing formation damage in producing zones.

APPLICATION :

Used as a bridging agent in drill-in and completion fluids and as a partial weighting agent in drilling muds. The different grades (F/M/C) allow for multi-modal bridging to seal permeable formations while enabling later clean-up with acid treatments.

ADVANTAGES :

  • Acid-soluble, allowing easy post-job clean-up.
  • Available in controlled particle size distribution (F/M/C).
  • Compatible with water-based, oil-based, and synthetic-based systems.
  • Helps control fluid loss and stabilize the wellbore.
  • Can be used to adjust mud density within desired limits.
  • Non-toxic, non-hazardous, and easy to handle.
