PVT Systems

System for PVT Studies & Wax/Asphaltene Precipitation Studies

Manufacturer: Vinci Technologies
Model Number: Fluid Eval

The Fluid Eval PVT system is designed to study phase behavior of hydrocarbon fluids at reservoir conditions of pressure and temperature. It can be used to perform PVT tests on black oil, volatile oil and gas condensate samples. It can also be configured with additional infrared, laser based solid detection system (SDS) and high pressure microscope (HPM) to perform a variety of asphaltenes and wax solid deposition experiments. The system uses an embedded high pressure pump to control the pressure and volume of the reservoir fluid in the cell. The unit can be configured for either oil or gas condensates studies by inverting the position of the cell using the motorized rocking system. A video camera system automatically determines the gas/liquid interface and measures the volume of retrograde condensate during gas condensate studies. 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 a controlled temperature air bath which can also be configured for sub-ambient temperature.



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.



Mobile PVT System for Field Tests

Manufacturer: Vinci Technologies
Model Number: Fluid Eval Mobile

The mobile Fluid Eval PVT system is designed to perform PVT tests on reservoir fluids at the field location or in the laboratory. The system uses an embedded high pressure pump to control the pressure and volume of the reservoir fluid in the cell. The unit can be configured for either oil or gas condensates studies by inverting the position of the cell. A video camera system automatically determines the gas/liquid interface and measures the volume of retrograde condensate during gas condensate studies. A magnetic coupled stirrer mounted inside the sample chamber provides efficient fluid mixing and ensures fast equilibrium of sample phases. Sample heating is provided by an heating jacket wrapped around the cell.



PVT System – Educational

Manufacturer: Vinci Technologies
Model Number: Fluid Eval - Educational

The educational Fluid Eval instrument is a compact PVT cell designed for the study of PVT, thermodynamic properties and phase behaviour of black oil and gas condensate samples requiring a small volume of fluid sample. The PVT cell is composed of an efficient fluid mixer mounted on the piston, a dedicated visual head, two sampling valves, an accurate pressure transducer and an electric heater for homogeneous temperature control . A digital camera system permits observation of the liquid/gas interface through the sapphire windows. During differential vaporization and flash test, the removal of the gas phase is facilitated by the full visibility of the gas/oil interface through the window of the cell. The unit can be configured for either oil or gas condensates studies by inverting the position of the cell.
