Abstract This work reports the characterization of organo-sepiolite (OSep) and the evaluation of the rheological properties of OSep in oil-based drilling fluids. Sepiolite was modified with benzyl dimethyl octadecyl ammonium chloride and OSep samples were prepared. X-ray diffraction, scanning electron microscope, specific surface area and thermal analysis were applied to characterize the structure of OSep. Viscosity, yield point, dynamic rheological behavior and thixotropy were used to appraise… CONTINUE READING
