Currently in Brazilian deposits of bentonite clays there are clays with a high percentage of coarse fractions, which have a negative influence on the rheological properties of dispersions prepared with these clays, precluding its use in aqueous drilling fluids of oil wells. The use of a blending with available samples has been industrially used successfully. Therefore, the present study aimed, and using the methodology of modeling blends with simplex centroid network planning with subsequent purification by hydrocycloning and drying in kiln and by spray dryer, optimize the rheological properties of dispersions prepared from mixtures of little noble bentonite clays, from the city of Boa Vista PB, in order to obtain drilling fluids that ans...
