This paper describes the construction and testing of a simple, experimental tool setup that enables determination of the pressure-viscosity relationship for high viscosity oils. Comparing the determined pressure-viscosity relationship with a reference rheometer measuring the viscosity at ambient pressure yields reasonable agreement. The computed viscosity at elevated pressures where well represented by the Chu and Cameron model.
