The results of the application of the statistical method for forecasting the oil and gas potential of tectonic-concentric structures of the Far East of Russia using reference territories

Abstract

The paper presents the results of using the statistical method to analyze geological and geophysical data measured within several tectonic-concentric structures in oil and gas-bearing regions in the Far East of the Russian Federation (depth of the Mohorovichi surface, depth of the the lithosphere bottom, values of geothermal energy). The distribution and values of some statistical parameters (histograms, distribution densities, probabilities, median and mean values) used for forecasting zones of hydrocarbon deposits location have been calculated. It was found that the most informative initial data used for statistical prediction of areas of location of oil and gas deposits are the presence of concentric zones at the depth of the Mohorovichich surface, and concentric inhomogeneites at the lower boundary of the lithosphere associated with the «root» structures of paleo-mantle plumes. Based on the calculated statistical parameters, four local tectonic-concentric structures promising for prospecting new oil and gas fields were identified.
