Abstract
We tested the effect of three types of soil inSaudi Arabiaon SABIC carbon steel grade X60 (SCSX60) specimens. The results showed that the environment effect of different condition was very clear, indicating that the studied soils were very corrosive SCSX60 specimens. The composition and morphology of corrosion were different in the tested soil based on moisture content and immersion period. In addition, the results showed that bacteria play an important role in the corrosion of SCSX60. The morphologies of corrosion products were analyzed using scanning electron microscopy to further elucidate the complex systems found in the studied soil.
Highlights
In oilfield operations, deteriorating effects such as the corrosion of equipment and installations, plugging of petroleum formation, and souring of the reservoir and fluids are caused by the activity of microorganisms [1,2,3]
We tested the effect of three types of soil in Saudi Arabia on Saudi Basic Industries Corporation (SABIC) carbon steel grade X60 (SCSX60) specimens
The aim of this study was to elucidate the effect of the environment on SABIC carbon steel grade X60 (SCSX60) specimens, which are a pipeline type of steel that extend beneath the soil in several areas of Saudi Arabia
Summary
In oilfield operations, deteriorating effects such as the corrosion of equipment and installations, plugging of petroleum formation, and souring of the reservoir and fluids are caused by the activity of microorganisms [1,2,3]. For example in the oil and gas industry, 34% of corrosion damage experienced by one oil company was believed to be related to microorganisms [4,5]. Microorganisms from a biofilm on the metal surface, thereby contributing to corrosion reactions [6,7,8]. The dissolution of metals both directly and indirectly related to the activities of microorganisms is known as biocorrosion or microbiologically influenced corrosion (MIC). This process is not a distinct mechanism of corrosion; rather, it consists of the activity of microorganisms during normal corrosion processes [9,10,11]. One of the most useful methods for studying the behavior of steel in soil with different concentrations of the masstour is the activity of microorganisms in soil
