PVT
(Pressure-Volume-Temperature)
The introduction of microfluidic techniques into conducting PVT (Pressure-Volume-Temperature) tests offers the opportunity to more deeply understand and predict the behavior of fluids under reservoir conditions, as well as significantly reduce the costs of conducting research and increase the accuracy of results.
PVT tests
The application of microfluidic techniques to Pressure-Volume-Temperature (PVT) tests offers the opportunity to enhance understanding and predict fluid behavior under reservoir conditions, while also significantly reducing study costs and increasing accuracy.
LABADVANCE can fully replace traditional CCE (Constant Composition Expansion) and CVD (Constant Volume Depletion) tests.

Methodology of PVT tests
The constant volume depletion (CVD) test is typically used for gas condensate fluids and volatile oils. A constant composition expansion (CCE) test is used for other purposes when there is a need to determine the saturation pressure and two-phase volumetric behavior.
The PVT microfluidic test procedure involves filling a microfluidic chip with a hydrocarbon phase - gas or liquid - under thermobaric conditions of the reservoir. Further, by gradually reducing the pressure in the system, the first bubble that appears in the oil or the first drop of gas condensate in the gas is visually detected. Such approach is more accurate since the size of detectable object is much less than for standard PVT cells.
