Corrosion in oil and gas industry promotes persistent challenges, affecting material integrity, and operational costs. Acidizing treatments commonly employed to enhance oil recovery increase corrosion, particularly in operations exposed to strong acidic environments. The need for efficient inhibitors is therefore essential for protecting pipeline and oil well materials. Imidazolium Ionic liquids offer several advantages, including negligible vapor pressure, high thermal and chemical stability, non-flammability, strong ionic conductivity, and structural tunability. The potential of these Ionic liquids as inhibitors makes them eco-friendly corrosion mitigation products compared to conventionally inhibitors. This study investigates the corrosion inhibition performance of two Imidazolium-based Ionic liquids on carbon steel alloy, 1-ethyl-3-methylimidazolium acetate (EMIM-Ac) and 1-methylimidazolium bis (trifluoromethyl sulfonyl) imide (BMIM-TFSI) in 0.5 M H₂SO₄ solution. Their performance is tested using weight-loss analysis, electrochemical measurements, and surface characterization via scanning electron microscopy (SEM) along with energy-dispersive X-ray spectroscopy (EDX).
