What's Bentonite?
Bentonite is a clay minral predominantly consisting of mineral Montmorillonite mixed
with some related minerals like Nontronite and Beidelite. These are three layered
aluminosilicate with molecules of water between layers. For natural Sodium Bentonite,
exchangeable sodium cations are predominant, rather than other cations like calcium,
magnesium etc. Similarly in Calcium Bentonite, calcium cations are predominant.
Generally speaking, the sodium variety has high swelling and gelling properities
as well as good viscosity and liquid limit. So the properties of Sodium Bentonite is
better than Calcium Bentonite. Sodium Bentonite is more popularly used in industries.
Feature:
good adhesion/good suspension/good lubricity/good thixotropy
good plasticity/good catalytic/good exchangeability/good adsorbability

Advantage:
Bentonite has the characteristic of high mud yield, high gel strength and low shear.
It can improve the borehole stability especially in unconsolidated formation. The
high performance and low concentration of bentonite can reduce the dosage,
cost and intensity of labor.
Application:
Used for oil and gas well drilling and civil-engineering including drilling fluid system for
horizontal directional drilling, fluid solution for diaphragm walls and piles, lubrication
fluids for micro tunneling or pipe jacking, drilling fluids for water well, exploration and
mining, fluid solution for shield tunneling.
