Welcome to Imerys Performance Minerals

Oilfield solutions

Oilfield solutions

Imerys has a long history of supplying materials to the Oil & Gas sector. Our products are used mainly  upstream, specifically in  drilling fluids,  oil-well cementing and completion phases.

Drilling fluids

Imerys minerals are key components in drilling fluids.  Drilling fluids are designed to control downhole pressure and support the wellbore; to remove cuttings from the bit and to effectively carry them to the surface; and to cool and lubricate the bit and drill string.

Calcium Carbonate

Imerys Calcium Carbonate is produced from high-purity marble deposits with high acid solubility.  It is used as a bridging agent for fluid loss applications and as a weighting agent.

We offer a wide range of particle size distributions ranging from 2 micron to 2,400 micron.

Diatomaceous Earth

Imerys supplies Diatomaceous Earth as a LCM (lost circulation material). DE is typically blended with other minerals and fibers to create a “squeeze” treatment.   DE is highly permeable which makes it effective to rapidly form a plug and create a seal in the loss zone.


Imerys Mica is produced from a high-purity phlogopite Mica deposit. It is used as LCM (lost circulation material).

We offer fine, medium and coarse grades.


Oil Well cementing is the process of mixing and placing a cement slurry in the annular space between a string of casing and the open hole. The cement sets, bonding the casing to the wall of the wellbore for additional stability.


Imerys supplies ground Perlite as a strength enhancer additive. Perlite which is high in amorphous silica, reacts with cement providing increased strength. In addition to its super pozzolanic properties, Perlite is lightweight.

Diatomaceous Earth

Imerys Diatomaceous Earth is used as cement extender additive. Extender additives are useful in loss circulation applications. Unlike other cement extenders, Diatomaceous earth will result in an increased compressive strength.

We offer a full range of custom formulation and technical and process support services to help you match the right mineral grade to your application requirement.
