API 13A Section 9 Bentonite – High Yield Sodium Bentonite in Mp
Filtron Envirotech (India) is a leading Manufacturer, Exporter & Supplier of Bentonite Extenders for drilling operations in Madhya Pradesh. With the state's large-scale infrastructure projects—including metro rail, expressways, and the Indore-Bhopal corridor—our bentonite extenders enhance the performance of drilling fluids, reducing costs and improving operational efficiency for contractors across Madhya Pradesh.
Bentonite Extenders are chemical additives that improve the yield and performance of bentonite-based drilling fluids, reducing the amount of bentonite required while maintaining viscosity and fluid loss control. In Madhya Pradesh, our extenders are used on infrastructure projects, for foundation piling, and for geotechnical drilling across the state. These products significantly reduce drilling costs and improve mud properties in the diverse soil conditions of Madhya Pradesh.

This bentonite grade rapidly disperses in fresh water, building a stable gel structure that keeps cuttings in suspension while the mud is static and flows easily when circulated. The fine particle size ensures deep filtration control, creating a smooth, low‑permeability wall cake that minimizes differential sticking. Beyond drilling, it serves in slurry trenching, diaphragm walls, and as a low‑permeability sealant for ponds and landfills. Its API compliance guarantees consistent performance across batches.
Advantages:
- High yield & rapid hydration – Reaches target viscosity quickly with less material.
- Superior cutting suspension – Prevents settling in deviated and horizontal sections.
- Low API fluid loss – Builds a thin, tough filter cake that seals porous zones.
- Excellent borehole stabilization – Reduces washouts and cavings in unconsolidated formations.
- Versatile mixing – Can be pre‑hydrated or added directly through hopper into fresh water.
