The inhibitory impact of low-cost synthesized pyrazoline derivatives named Pz series ( Pz1 and Pz2 ) on the corrosion of API 5L X60 carbon steel in 5 M HCl was inspected to serve as corrosion inhibitors against such a solution for its usage in the oilfield well acidization process. Also, the same compounds were unitized as biocides for sulfate-reducing bacteria (SRBs) to inhibit the microbial-induced corrosion effect. This study was conducted via several electrochemical techniques, namely, electrochemical potentiodynamic polarization (EP) and electrochemical impedance spectroscopy (EIS), in addition to computational density functional theory (DFT). The inhibition efficiency (IE) of Pz series on the corrosion of 5L X60 carbon steel in 5 M HCl was found to increase whenever the Pz series molecule concentration was increased. EP measurements revealed that Pz1 and Pz2 have both cathodic and anodic features (mixed inhibitor) and their corrosion IEs were around 90%. The physicochemical properties of the Pz1 and Pz2 compounds were studied using Langmuir adsorption isotherms, where the equilibrium adsorption data were found to follow it accurately. EIS outputs were found to comply with the values obtained from EP. Scanning electron microscopy was used to examine the topographic anisotropy between the inhibited and uninhibited 5L X60 carbon steel samples to double-check the electrochemical findings. DFT calculations and Monte Carlo simulations were utilized to predict the behavior of inhibitors and to rationalize the experimental results. The serial dilution bioassay technique was used to assess the Pz series as potential biocides to counter the effect of SRBs in compliance with the TM0194-2014-SG standard test method, and the results showed the potency of Pz series in inhibiting such bacterial growth.

Biokorosi atau Microbiologically Influenced Corrosion (MIC) adalah salah satu bentuk korosi lokal yang dihasilkan dari mikroorganisme dan aktivitasnya yang mempunyai dampak negatif pada fasilitas di industri minyak dan gas. Keberadaan mikroorganisme dan aktivitasnya yang kompleks memainkan peranan penting dalam pembentukan biofilm dan produk korosi yang menyebabkan kerusakan peralatan. Meskipun beberapa teknik mitigasi dan pencegahan dalam usaha pengendalian mikroorganisme telah dilakukan, tinjauan tentang mitigasi korosi yang dipengaruhi mikroorganisme masih terbatas. Dalam tinjauan ini, dibahas jenis mikroorganisme terkait biokorosi, pembentukan biofilm, teknik deteksi dan evaluasi mikroorganisme, teknologi pencegahan dan pengendalian mikroorganisme di industri minyak dan gas. Perkembangan teknologi terkini pengendalian mikroorganisme di industri lainnya juga turut dibahas.

“…Additionally, the XPS results further confirm the existence of sulfides in corr products, which is consistent with the EDS results. FeS is the typical metabolic su generated by SRB activities, which can be embedded in an SRB biofilm [14,35,36]. The composition of corrosion products formed on the specimen surface in the SRBcontaining solution was further analyzed by XPS.…”

The influence of sulfate-reducing bacteria (SRB) on the corrosion behaviors of X80 pipeline steel was investigated in a soil environment by electrochemical techniques and surface analysis. It was found that SRB grew well in the acidic soil environment and further attached to the coupon surface, resulting in microbiologically influenced corrosion (MIC) of the steel. The corrosion process of X80 steel was significantly affected by the SRB biofilm on the steel surface. Steel corrosion was inhibited by the highly bioactive SRB biofilm at the early stage of the experiment, while SRB can accelerate the corrosion of steel at the later stage of the experiment. The steel surface suffered severe pitting corrosion in the SRB-containing soil solution.
