Assessment of the prospects of oil and gas-bearing areas in the waters of the Sea of Okhotsk based on the results of the application of probabilistic and statistical analysis of geological and geophysical data

The article presents the results of the application of the probabilistic and statistical method of forecasting the prospects of oil and gas-bearing areas in the waters of the Sea of Okhotsk. The method is based on the use of a preliminary analysis of statistical series of several different types of geological and geophysical parameters. The object of the study of this article is the local concentric structures in the waters of the Sea of Okhotsk. The subject of this article is the forecast of oil and gas bearing areas. The results of using a probabilistic statistical method for predicting the prospects of oil and gas-bearing areas for four types of different geological and geophysical data (crustal thickness, lithosphere thickness, sedimentary rock thickness, heat flux values) measured within the location of fifteen local concentric structures in the Sea of Okhotsk are considered. Based on these data, statistical histograms of the spatial distribution of the values of the thickness of the earth's crust, the thickness of the lithosphere, and the values of heat flux were previously constructed according to measurements in the main oil-producing regions of the Okhotsk, Black, and Caspian Seas. As a result, using the probabilistic forecasting method, the values of the probability distribution densities were calculated according to the data of various four geological and geophysical parameters. According to the calculated probability values for fifteen concentric structures of the Sea of Okhotsk, according to four types of geological and geophysical parameters, a summary data table was compiled and eight local concentric structures promising for the search for new oil and gas fields were identified.
