Bentonite: The Clay That Drinks Water and Built an Industry
Drop a gram of sodium bentonite in water and watch geology perform: the clay swells to many times its volume, unfolding into billions of microscopic plates that turn water into structured, cutting-carrying mud. That single property — montmorillonite’s thirst — underwrites the entire water-based drilling industry, and India’s Kutch belt sits among the world’s great sources of it.
Eleven grades, because one clay serves many masters
Drilling writes the deepest specification ladder in the mineral world. API 13A Sections 9, 10 and 11 (OCMA) define the certified drilling grades global tenders demand. High Yield and Extra High Yield stretch sack economics for water wells and remote logistics; Reduced Fluid Loss, High and Extra High Viscosity grades tune the clay’s contribution to the mud’s exact need; and Single Sack HDD pre-blends clay with polymer for trenchless crews boring under roads worldwide. Beyond drilling, Foundry grade binds the green-sand moulds of metal casting, and Bleaching grades absorb and decolourise. Every grade is a certificate: yield, viscometer readings, filtrate.
From Kutch to the wellsite
SIPL supplies the full matrix in 25 kg bags, jumbo bags and bulk, exporting from Gujarat’s mining belt to drilling and foundry customers across the Middle East, Africa and the USA.
