Vladivostok. July 2. VOSTOK-MEDIA - High oil prices, lingering for several years will not last forever.

According to the document, most current forecasts of oil prices do not take into account the importance of new technologies for the extraction of oil and gas from shale.According to the report, by 2020 the world oil market may change, equal to the turning point on the scale of the 1970s. However, if at that time the world price of oil jumped twice, this time the trend will be reversed direction.
