ABSTRACT
Oilfield wastewater is one of the single most significant waste streams in the oil and gas industry, and because it is a residue of complex chemical composition, it can't be simply discarded in the environment, it should receive appropriate treatments before disposal. This paper presents a mapping of the quantitative evolution, referring to the leading publications on the study of water produced with a focus on treatments. A qualitative method was then adopted to build a structured database with the selected articles and then analyzed the areas of impact, keywords, periodicals, and affiliations. The thematic has proved to be an essential line of research over the years. Several indicators were observed regarding the development of academic and technological research on water produced as well as its treatment processes. The study was performed and database was gotten from onfield experts, and 125 documents were identified, with 20 articles investigated more specifically. This paper highlights the need for constant future studies about the Oilfield wastewater to minimize not only pollution but also reduce operating costs.
