Environmental damage occurs throughout the stages of exploration, production, refining, transportation and end use consumption. Potential impacts include water contamination due to effluent of wash and cooling water discharges, seepage from storage and waste tanks, discharges of water effluents rich in inorganic salts without appropriate treatment and water contamination of oil spills which could be very catastrophic such as the incident of The Deepwater Horizon oil spill in the Gulf of Mexico in year 2010 and the oil spill resulting from the Gulf War in 1991. Also, this industry adds a considerable amount of NOx, SOx and particulate emissions and largely contribute to the soil and groundwater contamination resulting from the different chemical compounds and the produced
