The migration of oil in sediments and the accumulation in oil traps is still a problem not yet solved. After BAKER, KENNEDY and others, hydrocarbons may be solubilized by natural surfactants, i.e. salts (soaps) of fatty acids or naphthenic acids, and migrate in an emulsified stage or in micellar distribution. Accumulation in a trap is inaugurated by separation of the components. In a model experiment with columns filled with sand, we succeeded herewith in a system of paraffine oil, solubilized by sodium palmitate, and an enrichment of denitrifying bacteria adapted to palmitinic acid as a carbon source. Gas production in the sand was visible already the second day. Almost 99% of the hydrocarbons were entrapped in the sand after 30 days by the activity of the denitrifiers while in the control experiment, about 50% migrated through the column and the rest was filtered off nearly unchanged by the sand.
