Oil in Water, Radioactivity, Physical and Chemical properties Study for Produced Water from Heglig and Neem Oil Field

This study investigates the physical and chemical parameters, heavy metals, oil contents and radioactivity of Neem and Heglig field produced water to find adequate technique to be used for treatment of pollution measurements that exceed the limits of environmental legislation. For Heglig produced water all the analysis results were within the acceptable limits according to Ministry of Energy and Mining except for the oil content, TDS, NH3 and Fe which exceeded the allowable limits because of the cumulative effect due to the evaporation. Moreover, conversion of Heglig field produced water into a source of fresh water is feasible for field scale application by using bioremediation technique for oil in water treatment. For Neem field produced water the results of total hardness, alkalinity, pH, TDS, and E conductivity exceeded the acceptable limits according to Ministry of Energy and Mining and the elements Pb, Ag and radioactivity exceeded by a large margin the acceptable limits while the result for oil in water was less than 1ppm, which is in the acceptable limit. Bioremediation treatment for Neem field produced water is useless, and the plantation of Phragmites Australis is suggested to be replaced by phytoremediation plant such as (Brassica juncea L, Sorghastrum nutans, Helianthus annuus, Gleditsia triacanthos, and Brassica) for treatment of heavy metals (Pb and Ag) that exceed the acceptable limits.
