Abstract:
A system and a method are provided for determining a viscosity of a fluid in a rock formation. The method includes determining a Stoneley mobility using a Stoneley wave measurement in a rock formation containing a fluid; determining a wireline formation tester (WFT) downhole fluid analysis (DFA) mobility by using a wireline formation tester in the rock formation; and determining a viscosity of the fluid based on the Stoneley mobility and the wireline formation tester (WFT) downhole fluid analysis (DFA) mobility.
