“…In Fe 2p spectra, peaks at 710.30, 711.30, 712.30, 718.80, and 725.30 eV correspond to FeS x [22], Fe 2 O 3 , FeOOH, Fe, and FeCO 3 [23], respectively. FeS x is the typical products of SRB corrosion, and FeCO 3 is the typical products of CO 2 corrosion [24,25]. In Cr 2p spectra, peaks at 577.20 and 586.80 eV correspond to Cr 2 O 3 and Cr(OH) 3 respectively.…”

Microbiologically influenced corrosion has become a predominant cause of pipeline and equipment failure in oil and gas fields. This research examines the corrosion behavior of steels with varying chromium contents in simulated shale gas formation water environments. Weight loss testing, Scanning Electron Microscopy (SEM), Energy Dispersive X-ray Spectroscopy (EDS), Focused Ion Beam (FIB), Transmission Electron Microscopy (TEM), and X-Ray Photoelectron Spectroscopy (XPS) were employed. The findings suggest that an elevated Cr content in steel results in a gradual reduction in its uniform corrosion rate in a CO2-SRB coexistence environment. This can be primarily attributed to the significant distribution of Cr content throughout the entire product film, including both biofilm and corrosion products, thereby enhancing the product film's protectiveness. Additionally, the competitive corrosion between CO2 and SRB, as well as the influence mechanism of Cr on corrosion, were discussed.
