Corrosion Inhibitors for Acidizing Process in Oil and Gas Sectors

The inhibition performance of a novel benzenesulfonamide-based benzoxazine compound in the corrosion of X60 carbon steel in an acidizing environment

“…40 Table 3 gives the values of the PDP parameters aer tting the plots. The inhibition efficiency of the BSB inhibitor was calculated using eqn (6).…”

“…[3][4][5] Mineral acids such as hydrouoric acid (HF), nitric acid (HNO 3 ), hydrochloric acid (HCl), and organic acids; formic acid (HCOOH), acetic acid (CH 3 COOH), chloroacetic acid (ClCH 2 COOH), sulfonic acid (RSO 2 OH), and sulfamic acid (H 2 NSO 2 OH), are used to dissolve rubble, remove mud and to create channels through rocks to access the crude oil. 6 The carbon steel employed for oil explorations in wells is susceptible to corrosion, due to the harsh working conditions of the oil wells, with acid solutions used as solvents to dissolve the rocks at the drilling sites. Today, this practice is adopted worldwide to enhance large oil and gas production, and the method of using (5-28%) HCl is reported as the most prominent.…”

“…17 In the oil wells, the use of corrosion inhibitors has proven to be easily practicable, efficient, and nancially more economical. 6 The inhibitors are adsorbed to form protective layers over the surface of the substrates, to prevent it from the ions of the corrosion environment. 18 Some inorganic inhibitors such as salts of nitrate (NO 2 À ), molybdate, (MoO 3 À ), chromate (CrO 4 2À ), phosphate (H 2 PO 3 À ), and silicate, in the presence of arsenic, zinc, nickel, and copper have been used to mitigate corrosion at high temperature with efficient performance and are relatively inexpensive compared to the organic inhibitors.…”

Multifunctional Aspects of the Synthesized Pyrazoline Derivatives for AP1 5L X60 Steel Protection Against MIC and Acidization: Electrochemical, In Silico, and SRB Insights

“… 4 − 7 On the other hand, corrosion induced by hydrochloric acid well stimulation job is considered as a major problem in the oil and gas industry as it leads to significant loss due to the severe corrosive act and high maintenance cost. 8 …”

The synergistic influence of polyethyleneimine-grafted graphene oxide and iodide for the protection of steel in acidizing conditions

“…Accordingly, to protect and prolong the life of steel structures, it is a common practice to use organic compounds as corrosion inhibitors. [16][17][18][19][20][21][22][23] These organic inhibitors are mainly nitrogen-containing organic compounds such as azoles, imidazolines, pyridines, and pyrimidines. [24][25][26] However, the synthesis of these organic compounds requires long synthetic steps, and the requirement of high concentrations in strongly acidic environments increases the cost of their application.…”
