Abstract

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.
