International practice lacks a clear-cut unified definition of shale hosted energy resources, namely, oil and gas. In the USA, same companies produce conventional and shale hydrocarbons on the basis of the common infrastructure. Preferential tax treatment additionally encourages oil companies to expand production. Some of the US states possessing large resources of shale oil and gas are sparsely populated, and therefore, actually no one can feel negative environmental effects of shale hosted energy resource development. Apparently, negative environmental consequences of shale hydrocarbon production will be minimized. Presumably, some volumes of shale oil and gas will be produced in Russia, as advanced methods and approaches are already available there.
