[57] Abstract: System, methods, and apparatuses for determining properties of a production fluid downhole are presented. In one instance, a system includes a sample-filled sensing device for vibrating a first suspended tube containing a sample of production fluid and producing a first response signal. The system also includes a reference-fluid sensing device with a second suspended tube containing a viscosity-tunable fluid therein. The system vibrates the second suspended tube to create a second response signal. The viscosity of the viscosity-tunable fluid is varied until it is deemed to match that of the sample production fluid. Other systems and methods are presented.
