| description | A method of acquiring viscosity of a downhole fluid is provided. The downhole fluid is in a downhole tool positionable in a wellbore penetrating a subterranean formation. The method involves obtaining a viscosity signal of the downhole fluid using a vibrating wire viscometer of the downhole tool, and acquiring viscosity parameters of the viscosity signal. The acquiring involves adjusting the viscosity signal by removing offsets from the viscosity signal, generating a complex signal from the adjusted viscosity signal, obtaining a low frequency component of the complex signal by filtering the complex signal into a high frequency component and the low frequency component and removing the high frequency component, and determining the viscosity parameters from the low frequency component. |
