Abstract


Since the past decades, the increasing of anthropogenic activities, especially in oil and gas industrial areas have affected the environment (air, water and soil). This is a global issue which happening throughout the world. Sudanalso faces these problems as it has been started development and production of oil since 1997 (over 20 years) at Muglad Basin (Heglig oilfield - Western Kordofan State).
Produced water is considered as a by-product of oil and gas production and most commonly treated as a waste for disposal rather than reuse and is the largest volume waste stream associated with oil and gas exploration and
production. Recently produced water quantities in Sudan oilfields (Western Kordofan State) increased rapidly due to the increase of the water cut percentage of the produced wells for all productive oilfields. Bioremediation projects were constructed to treat the produced water coming from Central Processing Facilities (CPF) at Heglig, Baleela,
Al barasaya and other Field Production Facilities (FPF). The discharge of the treated produced water used ONLY for irrigation of forests area in GNPOC & PE oil fields located in Western Kordofan State in which the study was
carried out.
Globally as weather changes its pattern and climate in the worldwide, the demand of freshwater supply has increased. This problem is particularly occurring in Western states of Sudan includes Western Kordofan State where water resources are particularly stressed given unprecedented drought and competing demands for ever scarcer water.
This research paper will evaluate the integrated management system of the produced water for Heglig oilfield (case study) and its disposal for potential options of reuse.
