The “PIK-PVT” installation for reservoir fluid samples PVT studies

The PIT-PVT installation is designed to study the reservoir fluids phase behavior at conditions from reservoir to normal. The system includes a high-pressure cell with transparent window and movable piston for accurate volume and pressure measurement of reservoir mixture and test sample complete visualization. Phase boundary determination with volumes estimation is carried out using an optical-digital subsystem with a video camera. Magnetic mixer increases mixing speed and efficiency.

Research is carried out in accordance with GOST 153-39.2-048-2003.
