Visual PVT System for Reservoir Fluid Analysis

Manufacturer: Vinci Technologies
Model Number: Fluid Eval Visual

The fully visual Fluid Eval PVT system is designed to study phase behavior of reservoir fluids at reservoir conditions of pressure and temperature. The PVT cell is based on a window through cell offering full sample visibility. It is particularly interesting when visual observation of the fluid must be accomplished such as swelling tests, volatile oil studies, gas condensate studies, etc. The system uses an embedded high pressure pump to control the pressure and volume of the reservoir fluid in the cell. A motorized rocking system permits to rock the cell for faster recombination and also put the cell in the correct position before the fluid volume measurement takes place. A video camera system records in real time the fluid phases while video tools enable the end-user to retrieve the volume of each phase versus pressure and temperature. A magnetic coupled stirrer mounted inside the sample chamber provides efficient fluid mixing and ensures fast equilibrium of sample phases. Homogeneous sample heating is provided by heating cartridges inserted in the cell body.
