Abstract The current research aimed firstly to investigate the inhibiting effect of some novel gemini surfactants as corrosion inhibitors for pipeline steel grade API 5L X52 during acidizing process as well as during transportation of formation water in oilfields. The testing media were acidic medium (1 M HCl) and western desert well formation water in inhibitor concentration range (1-200 ppm). The second aim is to calculate some computational quantum-chemical parameters of the inhibitors by Chem Bio Draw Ultra 12 software and relate it to the inhibition efficiency. |
