Experimental Modelling of Hydrocarbon Migration Processes

Abstract

One of the most important questions in the frame of the concept of deep abiogenic origin of hydrocarbons is how hydrocarbons generated under the upper mantle conditions could migrate upward to the Earth's crust to form hydrocarbon deposits. Two different ways of fluid migration were proposed and simulated - slow migration during hundreds of years and fast migration-eruption. Influence of the fluid's migration speed on the final hydrocarbon mixture composition was studied. The received results show that the relative chemical composition of the hydrocarbon mixtures probably does not depend on the cooling conditions (the speed of the fluid migration).
