DRILLING GRADE BENTONITE POWDER

It has been finally balanced and believed to give optimum result in oil well drilling tube well drilling, pilling and grouting. this type of bentonite has high gelling and swelling capacity, small percentage of this type of bentonite gives very viscose slurry and at the same time fluid loss most satisfactory.
