Manufacturer: Vinci Technologies

Model Number: Fluid Eval

The Fluid Eval PVT system performs hydrocarbon phase behavior studies at reservoir-representative conditions of pressure and temperature. The apparatus warrants excellent reliability on black oil, volatile oil and gas condensate samples. It can also be configured with an infrared laser-based solid detection system (SDS) and high pressure microscope (HPM) to enable a variety of asphaltene and wax solid deposition experiments. The system utilizes an embedded high pressure pump to control and monitor the fluid’s pressure and volume within the cell. A single cell is employed for both oil and gas condensates studies. For oil studies, the cell is in the upright position whereas for gas condensate studies, it is inverted to maximize the dew point detection efficiency. Cell rotation is achieved via a powerful motorized rocking mechanism. A video camera system continuously surveils the gas/liquid interface and measures the volume of retrograde condensate during gas condensate studies. A magnetically coupled stirrer mounted inside the sample chamber provides efficient fluid mixing and ensures fast thermos-physical equilibrium. Homogeneous sample heating is generated by a controlled temperature air bath which can also be configured to deliver sub-ambient temperatures down to -20°C.
