HYDROCARBON PROSPECTS OF THE CHULAKANSKAYA AREA IN THE KRANOYARSK TERRITORY ACCORDING TO GEOCHEMICAL DATA

Abstract

Soil vapor survey o soil deposits exposed by erosion has been carried out on the Chulakanskaya area. The areal migration arch-like anomalous zone coinciding with the Chulakan uplift and the semicircular zone around the East Chulakan uplift have been mapped. The field of increased helium concentrations reflects elem of deep fault tectonics. The deposits prediction was conducted on the basis of the neural network modeling by the mathematical apparatus technique; the forecast is correlated with specified uplifts. The presence of the hydrocarbon migration shows on the Chulakanskaya area and the results of statistical processing of geochemical data indicate the possible existence of gas condensate accumulations with oil rims similar to the Sobinskoye one. The area is recommended for exploratory drilling.
