Viscosity measurement dataset for a water-based drilling mud-carbon nanotube suspension at high-pressure and high-temperature

This data article presents the measured viscosity of a carbon nanotube (CNT) suspension in water-based drilling mud, also termed as nano-muds ("Rheology of a colloidal suspension of carbon nanotube particles in a water-based drilling fluid" Anoop et al., 2019). The apparent viscosity values of the nano-mud samples are measured using a high-pressure high-temperature viscometer at different shear rates, working based on a rotor and bob technique. The pressure and temperature of the samples are independently varied during the measurements from ambient conditions to 171 MPa and 176 degrees C, respectively, within two experimental schedules. Viscosity measurements for varying nanoparticle concentration, shear rate, pressure, and temperature are reported here for different CNT concentrations. (C) 2019 The Author(s).
