Investigation of sulfate-reducing bacteria in produced water from the “Neft Daslari” OGED wells

Abstract

Sulfate-reducing bacteria (SRB) are recognized as key contributors to microbiologically influenced corrosion (MIC), a major challenge in oil and gas industries. These anaerobic microorganisms are capable of reducing sulfate ions (SO???) to hydrogen sulfide (H?S), thereby accelerating electrochemical corrosion processes on metallic surfaces. Moreover, SRB activity promotes biofilm formation, which further enhances the persistence and severity of corrosion. In this study, the presence of sulfate-reducing bacteria were investigated in produced water samples collected from the production wells of the “Neft Daslari” Oil and Gas Extraction Department. The obtained results contribute to understanding the microbial diversity and corrosion potential of subsurface environments associated with offshore oil extraction.
