Patterns of distribution of hard-to-recover oils with high content of resins and asphaltenes Available to Purchase

The spatial distribution of world reserves of high-asphaltene and high-resin oils as an important source of hydrocarbon raw materials in the future is studied. It is shown that one third of the world's oil and gas basins contains reserves of these oils. More than 88% of the world's reserves are located in Canada and Russia. About 94% of all Russian reserves of high asphaltene and high resinous oils are located in three basins: Timan-Pechora, West Siberian and Volga-Ural basins. It has been established on the basis of statistical investigations that high asphaltene and high resinous oils are characterized by increased density and viscosity, high content of sulfur, nitrogen, and oxygen, as well as vanadium and nickel. Regularities of changes in the content of resin-asphaltene components depending on the age of deposits, depth and lithological characteristics of reservoirs have been revealed. Maps of oil and gas basins were constructed on the basis of information from the database. These maps reflect the patterns of distribution of oil fields with high asphaltene and high resin oils on the territory of the basins and allow identifying areas of preferential localization of reserves of the oils under consideration.
