Unigel 21 is a cost-effective organically modified bentonite used as a gelling and viscosifier for primarily diesel-based drilling fluids.

Unigel 21 is used in the 2-10 lb/bbl (5.7-28.5 kg/m3) range depending on the desired viscosity properties, mixing system, and temperature. Higher concentrations are used when preparing spotting fluids, packer fluids or other special systems. Maximum viscosity is normally attained after a complete circulation of the fluid thru the bit, so care must be taken not to over-treat upon initial mixing.
