Nanoclays in Drilling Fluids: Bentonite, Fibrous Clays, and What Goes Wrong

Thu, 19 Mar 2026 00:00:00 +0000

Bentonite’s largest single market by volume isn’t nanotechnology — it’s drilling. Every year, millions of tons of bentonite go downhole in drilling fluids used by the oil and gas, geothermal, mining, and water well industries. This is the oldest industrial application for the clay mineral that the nanoclay community has rebranded as a high-tech material, and it remains the application where clay performance is tested under the harshest real-world conditions: extreme temperatures, crushing pressures, corrosive brines, and rock formations that punish any formulation weakness.
