A mathematical modelling was developed based on the theory of mass balance for the oil spills dispersion simulation. The model was tested in Dumai waters, PT. Caltex Pacific Indonesia, and eventually compared with reference model of Worldwide Oil Spill Modelling (WOSM). Dispersion model calculation was based on the spills of 1000 Barrels of Sumatran Light Oil. The simulation demonstrated that the concentration of oil dispersion with 10 m depth after 24 hours was 1.84 x 10-1 gr/m3, while the simulation result of WOSM was 8.84 x 103 gr/m3. The difference was due to the fact that the model was developed by a very simple assumption, that is only taking into account the advection process but not the transformation factor.
