One of the main directions determining the development of the oil industry is the discovery of new super-deep oil deposits. The super-deep deposits are the most promising objects for increasing the hydrocarbon resource base in industrially developed areas. It is necessary to develop deep drilling technologies to extract oil from super-deep deposits, which in turn requires reliable data on the phase behavior of oils at ultra-high thermobaric parameters. Understanding the phase behavior of oils with changes in thermobaric parameters is of interest not only from an applied point of view but also from the physics of disordered multicomponent systems. The results of the experimental study of two oil samples with a change in pressure to 1,4 GPa in the temperature range of 240–340 K presented in this paper allow us to expand our understanding of the phase behavior of complex hydrocarbon systems at ultra-high pressures.
