Concentration and Composition of Hydrocarbons in the Area of the Kravtsovskoe Deposit in the Baltic Sea

摘要

The total concentration of hydrocarbons (HC) of various genesis coming to the Baltic Sea is estimated as 150000 tons per year; 56 wt % of which relates to autochthonous, 17.4 wt %, to allochthonous, 23.3 wt %, to antropogene, and 3.3 wt %, to petro-genic (coming from bottom sediments) components [ 1 ]. The two latter sources are located in the most nav?igable areas and in the places of exploitation of oil deposits. On average, the losses to modern oil deposits at the expense of flooding are 10~(-4) to 10~(-5) vol % of total oil production on the shelf [2].
