OBM Organophilic Clay For Invert emulsion fluids | Workover fluids        

OBM Organophilic Clay CP-160 mainly use for synthetic oil,linear and isomerized Alpha Olefins,modified vegetable oil, all oil based drilling fluids ,Invert emulsion fluids,workover fluids,fracture fluids.

OBM Organophilic Clay is an easy dispersing, self activating organoclay that exhibits high performance efficiency in diesel, low aromatic mineral oil, modified vegetable oil and synthetic base fluid formulation. CP-160 unique rheological structure suspends weighting materials and other solids with less increase in viscosity and gel strength than conventional bentonite. It is highly effective in distillate and mineral oil based invert fluids.
