Abstract
Abstract Corrosion of X80 steel was investigated in simulated acidizing fluids containing different concentrations of 3-(2-chloro-5,6-dihydrobenzo[b][1]benzazepin-11-yl)-N,N-dimethylpropan-1-amine (3CDA) at different temperatures using weight loss and electrochemical techniques. X80 steel used corroded at higher rates in the uninhibited acid solution than in the inhibited solutions. Inhibition efficiency of 3CDA was highest (88.8%) at 10 × 10−5 M concentration at 30 °C and decreased as temperature decreased. Some intensifiers were added to improve the inhibition efficiency at high temperatures. The 3CDA acts as mixed type inhibitor and adsorbs spontaneously on steel surface by physical and chemical interactive forces. Techniques such as FTIR, SEM and EDAX were also employed to characterize the potential of 3CDA as efficient steel corrosion inhibitor for oilfield application.
