The discharge of produced water accounts for the largest volume of waste associated with offshore oil and gas production operations. With the development and expansion of Iran's offshore gas reserves in the South Pars fields, there is concern over the potential long-term impacts of produced water discharges in the Persian Gulf. To deal with this emerging issue, the present study focused on modeling and assessment of environmental impacts associated with produced water discharges based on the integration of Gulf hydrodynamic and oily components dispersion models. It provides three-dimensional hydrodynamic input to a Random Walk model focused on the dispersion of oily pollutant components within the produced water effluent stream at a regional spatial scale. In this paper at first the quantity and quality of produced water are measured and reported for one year and some statistical reviews has done. Determination of the oil content of effluent water - Extraction and infra-red spectrometric and OSPAR Reference Method which is the standard method for dispersed oil in produced water analysis in the UK for both oil and gas facilities was used as standard method. Advection, diffusion and fate of oil spills by wind and tidal currents and transport are indirectly taken into account in this study. Hydrodynamic, oil spill and path of the oil pollutants in Offshore Gas Platforms in South Pars Gas Field in 3 month has been simulated in a few scenarios. The results of modeling in this research approved the risk of oily components pollution nearby of onshore ecosystems through 3 months.
