The deployment of plant extracts as inhibitors in corrosion protection of carbon steel is widely praised considering their biodegradability, availability and nontoxic attributes. However, their performance as corrosion inhibitors for a wellbore in an unmodified state is limited due to solubility-related issues and thermal degradation in the environments obtainable during oil well acidizing. The present study synthesized a Dillenia suffruticosa leave extract (DSLE)-mediated NiO nanocomposite for a matrix acidizing oil well environment using biosynthesis technique. The biosynthesized DSLE-NiO nanocomposite was intensively characterized using UV–vis, XRD, TEM and SEM/EDX techniques. The corrosion inhibition performance of the synthesized nanocomposite studied by gravimetric and electrochemical characterization (PDP and EIS) revealed that this nanocomposite could moderately inhibit corrosion of C-steel in an oil well acidizing environment up to an average inhibition efficiency (IE) of 65.4 % at an optimum concentration of 1000 ppm. This efficiency was significantly increased by modifying the DSLE-NiO nanocomposite with sodium iodide (NaI) to 95.2 % at the same concentration. The surface assessment using SEM/EDX affirmed that iodide species significantly enhanced the inhibition performance of the DSLE-NiO nanocomposite in corrosion protection of C-steel in the acidizing solution. This investigation promotes the application of carbon steel-made well casing for matrix acidizing oil well operations in the oil and gas industry.
