The PIT-PVT-light installation is designed to study the reservoir fluids phase behavior at conditions from reservoir to normal. Main element of the system are pumps installed in a heating cabinet and providing a fluid sample circulation in a closed circuit. The circuit includes a high-pressure and temperature densitometer, a capillary for viscosity measuring, and a high-precision differential pressure sensor. The installation includes a manual gas meter.
Research is carried out in accordance with GOST 153-39.2-048-2003.
