Subject: GEOPHYSICAL METHODS OF EXPLORATIONS FOR DEPOSITS OF HYDROCARBONS


The goal of the course is to provide students with theoretical fundamentals for optimal complex of geophysical research in oil and gas industry. Main and supplementary methods of explorations for and survey for hydrocarbon raw materials in conditions of Western, Eastern and South oil and gas basins of Ukraine. Interpretation of geological-geophysical data using modern computer technologies. Geological-economic evaluation of prepared perspective sites and objects.
