Acid-Soluble Carbonates

Imerys produces a range of ground carbonate powders which can be used as lost circulation materials, as drill-in fluids and as weighting agents. Imerys carbonate portfolio is composed of highly soluble sized marble, limestone calcium carbonates and dolomite powders from a range of global locations.

Properties
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.
