Leaves extract of Gingko biloba (GBE) was characterized using mass spectrometry (MS) and Fourier transform infrared spectroscopy (FTIR) methods. The influence of GBE on corrosion of carbon steels (J55,N80, P110SS and C110 steels) in 3.5 wt.% NaCl solution saturated with CO2 was evaluated using static high pressure and high temperature (HPHT) autoclave. The surface was further evaluated by X-ray diffraction (XRD), scanning electron microscopy (SEM), and contact angle measurements. SEM, XRD, and contact angle measurement studies reveal that the surface of metals are quite unaffected after use of inhibitor in 3.5% NaCl solution saturated with CO2.
