Scope: Measurement of Reservoir Fluid Viscosity by Rolling Ball Method


The Rolling Ball Viscometer is specially designed to determine the viscosity of reservoir liquids under reservoir conditions.

Experiment Description


The principle of operation is to measure the time that it takes for a ball to fall through the sample fluid. This effective approach is the most reliable technique to estimate oil viscosity at high pressure and high temperature conditions to simulate reservoir conditions.
