Imerys produces a range of ground carbonate powders which can be used 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.
A high-specific gravity and finely divided solid material used to increase density of a drilling fluid. Sufficient fluid density is required to maintain borehole stability and to prevent invasion of formation fluids into the well.
The use of acid-soluble weighting agents to drill producing zones is advantageous as they can be removed during well completion, thereby eliminating any formation damage that may have been caused.
Products from our large portfolio of carbonates (marble-based, limestone calcium carbonates and dolomite) have a specific gravity of 2.6 to 2.8 and unlike other weighting agent materials they are acid soluble.
To find a suitable product for your application from our large portfolio, go to our carbonates page.
All of our products are supported by a high standard of technical service and research and development from a team of highly experienced scientists and specialists.
