Calcium carbonate

Calcium carbonate (CaCO2)

Calcium carbonate (CaCO2) is a white, slightly alkaline, acid-soluble mineral widely used in oilfield fluids as a bridging and weighting material, and in many other industries as a filler and pigment.

  • Calcium carbonate in both offshore and onshore oilfield use, you can describe it like this:
     Used as an acid-soluble weighting agent to increase mud and drill-in fluid density while still allowing easy clean-up with acid (land and offshore wells).
  • Acts as a bridging / lost-circulation material, plugging pores and fractures to stop mud losses in onshore and offshore formations.
  • Builds a thin, tight, acid-soluble filter cake on the wellbore wall to control fluid loss in drilling, workover and completion fluids.
  • Plastics/rubber: Filler to improve stiffness and finish, and cut cost.
  • Paints/coatings: White extender for opacity and brightness.
  • Paper: Filler/coating for brighter, smoother sheets.
  • Construction: Component of cement, concrete and aggregates.
  • Agriculture: Liming agent to raise soil pH.
  • Pharma/food: Calcium source, antacid, and tablet/food filler.
