Imerys is the world's largest producer of diatomite, which is a natural filter aid used extensively in the filtration of high value completion fluids.
Once a reservoir section has been drilled, it is vital that formation damage is not caused by any subsequent completion operations before the well is brought on stream. At this stage well control is achieved using a completion fluid – usually a high density brine that contains no solids. Such fluids must be carefully filtered before injection downhole.
Calcined diatomaceous earth or diatomite and perlite are natural filter aid used widely in many industries. It is ideal for filtration of completion and workover fluids, and is commonly used in plate and frame filter units.
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.
