This study evaluated the physiochemical properties of produced water. The effective management of offshore E&P wastes is one of the challenges facing the oil and gas industry in Nigeria. Sampling points were carefully selected to obtain samples that are truly representatives of the post-treated produced water. The pH of the recipient marine water showed compliance with the DPR(Department of Petroleum Resources) standards unlike that of the produced water with a mean value of 6.33.The study concludes with the recommendation that the provisions of Environmental Guidelines and Standard for the Petroleum Industry (EGASPIN ) should be followed strictly to facilitate effective management of offshore E&P wastes in Nigeria as it is not in line with contemporary international standards as most of the parameters tested and analyzed are not within limit.
