Borregaard’s chrome-free BioDrill TM thinners are utilised to de-flocculate water-based bentonite clay systems, which in turn reduces low shear rate viscosity and gel strength. They also contribute to reducing fluid loss. The products have proven efficiency in various systems; including fresh water, brackish water and seawater, at bottom hole temperatures up to 100 °C (212 °F).
