With the decrease of production in conventional oil and gas resources, increasing attention is turning toward nonconventional oil sources to relieve the pressure caused by the lack of conventional stocks. Heavy oil and natural bitumen as two of the alternative sources are perhaps the most readily available to meet short- and long-term needs. As is well known, the physical and chemical properties of heavy oil and natural bitumen are quite different from conventional oils. Major differences include low content of th...

The current problem of the last decade in the world is the increase of oil production volume due to the extraction of its hard-to-recover reserves. The difficulty of its extraction is determined not only by the petro-physical characteristics of the oil-bearing formation, but also by the physico-chemical properties of the fluid itself. However, not all methods of enhancing oil recovery are ecologically safe. The most effective and ecologically-friendly method of soil purification from pollution by oil products is t...

With the decrease of conventional oil production, the role of heavy hydrocarbons in the world energy balance will continue to increase in the near future. Heavy oil and natural bitumen as two of the alternative sources are perhaps the most readily available to meet short- and long-term needs. Intrastratal oxidation requires a formation temperature in the range of 250-350пїЅC, at which it is possible to achieve an in-situ oil upgrading through the low-temperature oxidation reactions of petroleum hydrocarbons.
