Mobile PVT system for field PVT tests


The elegant yet robust mobile Fluid Eval PVT system adequately performs PVT studies in a laboratory or under the harsh site conditions, e.g. dust, vibrations, temperature fluctuations etc. The system utilizes an embedded high-pressure pump to control and monitor the fluid’s pressure and volume within the cell. The apparatus warrants excellent reliability on black oil, volatile oil and gas condensate samples. 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 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 thermophysical equilibrium. Homogeneous sample heating is generated by an efficient isothermal heating jacket.
