Increased oil production has resulted in the production of large amounts of produced water, which is a major problem for Kuwait Oil Company. Kuwait Oil Company generates large amounts of produced water daily and thus deserves special attention. A study of the characteristics of the produced water will determine how it can be treated and later used for irrigation or disposed without harming the environment. In this paper, samples of produced water from different oilfields in Kuwait were collected, and physiochemical analyses were carried out. The salt content, TDS and other physical characteristics of the Kuwait produced water samples were compared with those of other produced water samples from different oil-producing countries.展开更多

Only Al, Cr, Co, Cu, Fe, Pb, Ni, and Zn were found to be over-represented at the consumption point compared with the outdoor point, with wide variations among the sampling locations and elements. The highest increases were observed for Fe (135%) and Zn (123%), followed by Pb (69%), Co (58%), Cu (42%), Cr (31%), and Al (30%), and the lowest increase was observed for Ni (19%). In most cases, the increases in Cu, Fe, and Zn were inversely proportional to the conductivity and directly proportional to the Cl– concentration. In the outdoor samples, only Fe exceeded the US-EPA guideline (in 3% of the outdoor samples taken), whereas Fe, Pb, and Ni exceeded the US-EPA and WHO guidelines in 8.5%, 0.3%, and 1% of the indoor consumption point samples, respectively. Thus, leaching from household utilities may cause health concerns for consumers of drinking water in Kuwait. The increases in Fe were the highest in the summer (240%), and in this regard, Fe exhibited the greatest difference between summer and winter (the increase was 139% higher in the summer). The results of the present study may be useful for water production authorities and consumers in Kuwait and suggest the use of alternative new pipes with more resistant internal coatings and connecting techniques.展开更多
