DEUTERIUM DISTRIBUTION IN CRUDE-OIL

The aim of this paper is to rehabilitate informative potential of usin g deuterium as a natural tracer in geofluids investigations and to ill ustrate how the deuterium concentration from geological fluid links th e micro-scale effects to the macro-scale processes. Research on the de uterium concentration of crude oils formerly has highlighted the role of deuterium as a natural tracer during diagenesis. We discuss how the deuterium abundance in oil and water from sedimentary basins provides information on dynamics of hydrocarbons reservoirs. We can obtain qua litative and quantitative information about the dynamics of fluids fro m deposit by deuterium concentration monitoring from geofluids (gas-oi l-water).
