Corrosion mitigation in oil reservoirs during CO₂ injection using nanomaterials

Corrosion inhibition in metal structures particularly in the oil and gas sector has always been a crucial area of concern. From conventional cathodic and anodic protection, polymer coating, and alloying to the most recent techniques of laser ablation method were applied to reduce and/or prevent corrosion. Recently, various corrosion inhibitors were found to be more reliable in preventing or reducing the impacts of metal corrosion. Nonetheless, endeavors to develop noble nanomaterial-based, self-healing, and self-cleaning type of corrosion inhibitors is opening a new area in corrosion inhibition research. This chapter reviewed the current advances in the area of nanomaterials particularly nanofluids for corrosion inhibition purposes. The potential applications of various nanoparticles and the challenges were outlined. Different characterization and synthesis techniques were discussed, the mechanism of corrosion inhibition and the prospects were also highlighted.
