The produced water in oil and gas fields and its management methods are of great importance in oil and gas industry. Considering increasingly stringent environmental regulations, the industry is burdened with large costs annually due to treatment and disposal of such volumes. Global oil to water volume ratio is about 1:3 according to world average. Currently, due to water shortage and industry developments, a lot of researches are being conducted in order to find new water sources. Recent studies demonstrated that treated produced water has the potential of consumption in different industries. Consequently, high-quality water consumption can be prevented where such a quality is not required. In this paper, produced water treatment and different options of water reuse is studied.
