Characteristics of Viscosity of a Scale Inhibitor: An Experimental Study

Abstract The use of chemical scale inhibitors in the oil and gas industry for subsea installations has been presented a long time, but ever-increasing exploration HPHT (high pressure high temperature) wells put demands on knowledge how rheological properties such as viscosity behave under large pressures. This work reports new experimental data high-pressure using rotational rheometer, measured across range 0.1 MPa to 15 MPa, at temperatures from 273 K 298 K, broad shear rates, 100 $$s^{-1}$$ s - 1 1000 inhibitor. are used construct power-law regression model with fitting parameters. Results indicate that inhibitor shows near Newtonian behavior.
