Suspensions of bentonite in water are widely used across industries. The largest and best known use of bentonite suspension is as drilling mud. Due to its rheological properties and thixotropy of aqueous suspensions, bentonite is used as a mud constituent for oil and water well drilling. Its functions are mainly to stabilise the borehole, seal the borehole walls, and remove drill cuttings. Bentonite muds are thus employed for oil and water well drilling, tunnel, and microtunnel drilling.
