FEIZHOU suspension agent is an inorganophilic attapulgite which controls the settling of solids in WATER-based drilling fluids. FEIZHOU suspension agent' of low viscosity muds with u s unique rheological structure suspends weighting materials and other solids with less increase in viscosity and gel strength than conventional bentonite or hectorite based organoclays. This allows the formulation ndiminished penetration rates and cutting removal. FEIZHOU suspension agent can be used alone or in conjunction with conventional organoclays. The solids suspension capacity of a fluid which is already thickened with an organoclay can be increased by the addition of FEIZHOU, without substantially increasing the viscosity of the system.
