Bentonite for Drilling & Borewell Industry

Drilling-grade Bentonite for viscosity, cuttings suspension, lubrication and borehole support.

Bentonite for Stable Drilling-Fluid Systems

Rajeshri Natural Resources supplies Drilling Grade and Sodium Bentonite for water wells, borewells, geotechnical drilling and compatible drilling-fluid systems. After proper hydration, Bentonite helps develop viscosity, carry drill cuttings, lubricate drilling equipment and coat the borehole wall. Final performance depends on water chemistry, mixing conditions, dosage and the required drilling specification. API Specification 13A separately defines requirements for qualifying drilling-fluid materials, including Bentonite.

Viscosity Development

Properly hydrated Bentonite supports the required body and flow behaviour of drilling fluids.

Cuttings Suspension

Helps suspend and transport drilled soil and rock particles towards the surface.

Borehole Stability

Supports filter-cake development and helps reduce instability in suitable formations.

Frequently Asked Questions

What is the main function of Bentonite in drilling fluids?

It develops viscosity, suspends cuttings, supports lubrication and helps form a protective filter cake.

Is Sodium Bentonite suitable for borewell drilling?

It can be suitable where high swelling and viscosity are required, subject to water quality and field testing.

Is your Drilling Grade Bentonite API certified?

Material can be supplied against agreed specifications. API conformity or certification should only be considered confirmed when explicitly stated in the quotation and test certificate.

Does water quality affect Bentonite performance?

Yes. Hardness, salinity, pH and dissolved minerals can affect hydration and viscosity.

What packaging is available?

Drilling Bentonite can be supplied in standard bags, laminated bags or jumbo bags based on order volume.
