On the fundamentals of electrochemical corrosion of X65 steel in CO2-containing formation water in the presence of acetic acid in petroleum production

Electrochemical measurement, modeling, and prediction of corrosion inhibition efficiency of ternary mixtures of homologous surfactants in salt solution

“…The inductive semicircle is characteristic of dispersion in frequency probably due to the surface roughness and inhomogeneity [43,44]. The adsorption of species, such as [H + ] ads , or intermediate product [FeOH] ads on the electrode surface may also contribute to the inductive semicircle appearance during the relaxation process [7,10]. As surfactant concentration increases to the sac, the inductive semicircle gradually disappeared at low frequency and a 2nd capacitive semicircle started to appear and overlapped with the 1st capacitive semicircle in the middle of the whole frequency range, as shown in Fig.…”

“…However, carbon steel is easily corroded in environments that contain water and carbon dioxide (CO 2 ) [6][7][8][9][10]. As one of the main corrosion types in oil and gas industry, CO 2 attack can cause tremendous damage to pipelines and structural components in water and crude oil transportation [1,4,6,9,[11][12][13].…”

Experimental Investigation and Modeling of the Performance of Pure and Mixed Surfactant Inhibitors: Aggregation, Adsorption, and Corrosion Inhibition on Steel Pipe in Aqueous Phase

“…[1][2][3][4] However, carbon steel is easily corroded in environments that contain water and carbon dioxide (CO 2 ). [3][4][5][6][7] As one of the main corrosion types in the oil and gas industry, CO 2 related corrosion can cause tremendous damage to pipelines and structural components in water and crude oil transportation and thus threaten production and safety. [3][4][5][7][8][9] The annual direct cost of corrosion in United States has been estimated to be around 3.1% of the gross domestic product (GDP).…”

[3][4][5][7][8][9] The annual direct cost of corrosion in United States has been estimated to be around 3.1% of the gross domestic product (GDP). About 3.7% out of the total cost comes from the oil and gas industry, 7,10 which is mainly due to the corrosion of carbon steel.…”
