A method for determining viscosity, eta, of a fluid downhole, calls for performing a nuclear magnetic resonance (NMR) survey of the fluid; determining a longitudinal relaxation time, T1, and an apparent transverse relaxation time, T2app, for the fluid; forming a ratio R of T1/T2app for the fluid; and determining the viscosity, eta, according to the ratio, R. A computer program product for implementing the method is provided. |
