Bentonite in Drilling Mud

More about Bentonite: As bentonite contains of 60-80% montmorillonite it provides special properties such as swelling and adsorption. The triple-layer silicate can absorb an exceptional quantity of water and expands by a multiple of the original size. The inner surface of a gram of bentonite is 400–600 m – normal clay only has 2 m.

Bentonite: Properties and Occurrences

Bentonite usually forms from weathering of volcanic ash, most often in the presence of water. However, the term bentonite, as well as a similar clay called tonstein, has been used to describe clay beds of uncertain origin. For industrial purposes, two main classes of bentonite exist sodium and calcium bentonite.

1. Introduction

Bentonite has strong hygroscopicity and expansibility. It can absorb water by as much as 8–15 times its dry mass. When wet, it can expand by even up to 30-fold of its dry mass. Bentonite can be dispersed in aqueous medium as a viscous and suspended material. Bentonite solutions have viscous, variable, and lubricant properties.
