To date, the urgent task is to create PVT models that adequately reproduce the properties of reservoir hydrocarbon mixtures, based on both Black oil-type models and composite PVTi, PVTsim. Availability of reliable data on PVT properties of reservoir fluids plays a leading role in calculating oil and gas reservoir reserves, estimating oil recovery factors, well studies, numerical reservoir modeling and for making informed decisions when designing field development. In practice, the results of field, laboratory and theoretical studies are used simultaneously to justify the properties of natural hydrocarbon mixtures. At each of the noted stages, specialists strive to increase the reliability of the obtained data and to develop methods of their interpretation. Determination of the properties of reservoir fluids in the oil field is a prerequisite for the effective use of various methods of exposure to the bottomhole zone, the selection of equipment for well operation. Properties of formation fluids are determined by different thermobaric conditions and change depending on the current state of the reservoir and the characteristics of reservoir pressure changes. All known methods for determining the properties of reservoir fluids are divided into two groups: experimental and computational. Each group has both advantages and certain disadvantages.
