Attapulgite is a needle-like clay mineral composed of magnesium-aluminum silicate. Attapulgite and sepiolite have similar structures and both can be used in salt-water mud to provide low-shear rate viscosity for lifting cuttings out of the annulus and for barite suspension. Attapulgite and sepiolite are sometimes called "salt gel." attapulgite has no capability to control the filtration properties of the mud. For use as an oil-mud additive, the attapulgite clay is coated with quaternary amine, which makes it oil-dispersible and provides gel structure but does not improve the filter cake, unlike organophilic bentonite clay. Attapulgite has very good colloidal properties such as: specific features in dispersion, high temperature endurance, salt and alkali resistance, and also high adsorbing and de-coloring capabilities. Furthermore, this petroleum product has certain plastic and adhesive characters. When used in medicine, this lubricity additive physically binds to acids and toxic substances in the stomach and digestive tract. For that reason, it has often been used in antidiarrheal medications.
