Deep tight oil: regularity of distribution and physical and chemical properties

The article gives a classification of the different types of hard-to-recover oils, considered as the basis of growth in oil production in the medium term due to the depletion of easily accessible reserves. Based on analysis of data from the database of the Institute of Petroleum Chemistry, studied the characteristics of spatial distribution and physical and chemical properties of deep tight oils. The results can be used in the development of new and improvement of existing methods and technologies of refining and transportation of oil with abnormal physical and chemical properties, as well as to solve other problems of the oil industry.
