Abstract
An apparatus for estimating a viscosity or density of a fluid downhole includes a carrier configured to be conveyed through a borehole penetrating the earth. A pump is disposed at the carrier and configured to pump the fluid. A flow restriction element is configured to receive a flow of the fluid pumped by the pump and to reduce pressure of the fluid flowing through the flow restriction element. A sensor is configured to measure a differential pressure across the flow restriction element and to provide an output that is used to estimate the viscosity or density.
