Fig. 4.29 The ratio d, of oil hydrocarbon content in the upper sea layer of 1 m depth to the content
in the thick water layer as a function of geographical coordinates. The modeling results are
averaged by all seasons. It is supposed that the oil hydrocarbon concentration in ʩ ∪ʩ P and in oil R

and gas extraction zone is constant and is equal to 0.06 mg L − 1

Fig. 4.30 The map-scheme of yearly-averaged distribution of the oil hydrocarbons in the oil and
gas extraction zone of Vung Tau city in 2001. These estimations are calculated by means of the
model based on the initial data of 1994. The scale step is 0.01 mg L − 1

As seen from Fig. 4.30 , the stabilized distribution R O ðu; k;

z ; t Þ dz is suf ciently

well co-ordinated with the direction of the currents. The formation of a field with

increased oil hydrocarbon concentration situated near the Vung Tau shelf zone is
explained by the supposition that in the oil and gas extraction site the following
