Bentonite Drilling Powder – PetroDMO

Bentonite Powder. The term Bentonite was first used for a clay found in about 1890 in upper cretaceous tuff near Fort Benton, Montana. The main constituent, which is the determinant factor in the clay’s properties, is the clay mineral montmorillonite. This in turn, derives its name from a deposit at Montm.
