<p>The aim of this work is to critically discuss the feasibility of the implementation of electrochemical processes for the treatment of offshore oilfield produced water, including insights, gaps, challenges and opportunities. The main novelty of this article is the literature-based analysis of the benefits of applying electrochemical processes to produced water treatment, considering their implementation at different stages of the conventional treatment flow already adopted on oil platforms. In addition, the advantages and limitations reported in the literature are discussed when these processes are integrated with other technologies, such as membrane filtration and other advanced oxidation methods. Based on the comprehensive analysis performed, it can be stated that electrochemical processes represent a highly efficient method to reduce the content of organic contaminants and oils in oilfield produced water, although challenges such as the formation of chlorinated by-products still need to be overcome. The combination of electro-oxidation reactions and electrocoagulation processes emerge as an alternative to the disadvantageous formation of gaseous products by adjusting the operational conditions. In addition, coupling electrochemical processes with other treatment technologies has been shown to reduce oil and grease content by more than 90%, depending on feedwater characteristics and process configuration. Finally, this work emphasizes the need for further research at pilot and industrial scales to validate not only the economic but also the environmental viability of these technologies. This is crucial to advancing their technology readiness level, achieving up to large-scale applications.</p> Graphical abstract <p></p>
