Abstract:
A method for measuring viscosity in a borehole includes: pumping downhole fluid through at least one tube disposed in a carrier configured to be disposed in a borehole in an earth formation; taking at least one differential pressure measurement of the fluid in the at least one tube via a pressure transducer; and estimating a viscosity of the fluid based on the differential pressure measurement.
