Application possibilities of migration regularities of natural radioactive elements and their isotopes in the complex mineral resource exploration with special regard to hydrocarbon fluid prognose and reservoir study Pt. 1 and 2

Based primarily upon Soviet literature data, the author gives a survey, for the first time in Hungarian literature, of the most important results of radiometrical and radiohydrogeochemical research activity of more than 50 years. The extension of domestic hydrogeological and hydrogeochemical examinations to be performed for hydrocarbon exploration is suggested by determining the natural radioactive elements and their isotopes. Special emphasis is laid on the processing of water samples analyzed for some other purposes for U and Ra according to hydrocarbon geological (and uranium geological) aspects. These samples were taken in the mid-sixties from Hungary's hydrocarbon exploration wells. (A.L.)
