Under the real geological-physical conditions of displacement of viscous oil, the related anomalies are additionally strengthened also due to the content of asphaltenes, resins and paraffins therein, inhomogeneity of collectors with various properties, in particular, permeability; therewith, the displacement ratio is reduced with increase in viscosity. All that is complicated by insufficient knowledge of the mechanism of generation of asphalt, resin, and paraffin depositions, their impact on the properties of oils, in particular, temperature of saturation of oil with paraffin, surveys of the regularities of which do not provide the consensus as shown by the study. As it is known, a feature of development of oil and gas industry is the exploration of deposits of heavy high-viscous oil in order to increase the resource base of hydrocarbon raw materials, which is possible due to the development of energy-efficient and resourcesaving technologies for its development. That is explanation for the attention of the researchers to the problems related to production of the hard to recover and viscous oils in structurally complex strata. Therefore, this article is an attempt to analyze the interrelations between the composition and properties of oils and estimation of the temperature of saturation with paraffin subject to the experience gained by now. Prior to proceed with the results of the studies, it is necessary to analyze knowledge of this problem, pre-obtained results.
