Key words: : reservoir temperature, reservoir pressure, gas saturation of oil, oil field, correlation method.
New oil fields of various regions of the Earth are characterized by significantly diverse basic properties of oil and gas, and thermobaric conditions, which in most cases are substantially high (formation temperatures reach 200 °С and the reservoir pressures exceed 40-50 MPa.
The difficulty of obtaining information on the main properties of oil and gas, as well as the considerable complexity of the sampling of the samples and their PVT-study, determines the need to investigate the correlation relationships between the individual properties of oil and gas.
The properties of the formation fluids change not only when the thermobaric conditions change, but also from the well to the well, and also depends on the current state of the field development. The main goal of the work is to obtain some correlation relationships for some oil fields in the Islamic Republic of Iran, which differ not only in terms of their thermobaric conditions, but also in the basic properties of their reservoir fluids.
