Exploring the interplay of under-deposit corrosion and microbiologically influenced corrosion in the presence of deposits with varied electrical conductivities.

ABSTRACT: In oil and gas pipelines, the coexistence of native microorganisms with various solid compounds, such as corrosion products, scales, and reservoir sand, is well-established. However, research focused on understanding the collective impact of these components on carbon steel corrosion has been limited, with most studies concentrating on inert deposits like clay and sand. This study assessed the impact of electrically conductive deposits - magnetite (Fe₃O₄) and troilite (FeS) - on UDC and UDMC of carbon steel, employing silica (SiO₂) as an inert control. A multifaceted approach, combining international corrosion standards, microscopy, and molecular microbiology techniques demonstrated that abiotic corrosion rates correlated with the electrical conductivity of
