Calcium carbonate is composed of the crystalline mineral, calcite, which occurs naturally in the form of chalk, limestone or marble. Dolomite is also a naturally occurring crystalline mineral.
Imerys combine good quality feed materials, state of the art processing techniques and in depth market knowledge to generate a portfolio of products for the Drilling fluids industry.
Applications for Acid-soluble Carbonates
The high acid solubility of these calcium carbonates makes them readily removable.
The controlled particle size specifications of Imerys marble-based calcium carbonates makes them ideally suited for use as lost circulation materials especially as bridging materials and for the control of fluid loss in drill-in fluids, completion/workover fluids.
Carbonates are excellent acid soluble weighting agent in drilling, drill‐in and workover/completion fluids.
