Frequently Asked Questions
What is drilling grade bentonite
Drilling grade bentonite is a specially processed bentonite designed to prepare drilling fluids used in oil & gas water well horizontal directional drilling (HDD) geothermal and geotechnical drilling. It helps stabilize boreholes suspend drill cuttings control fluid loss and improve drilling efficiency.
What drilling applications is KORVANTO BENTO DRILL suitable for
Korvanto BENTO DRILL is suitable for a wide range of drilling applications including:
Oil & Gas Drilling
Water Well Drilling
