178:: Some studies have shown that certain pyridines can inhibit corrosion caused by the presence of acid gases, such as carbon dioxide and hydrogen sulfide, which are common in the oil industry. Pyridine and its derivatives have been shown to be effective inhibitors for a wide range of metals, such as carbon steel, stainless steel, and copper alloys. They act by adsorbing to the metal surface and forming a protective film, which can be physical or chemical in nature. Pyridine and its derivatives are also effective in inhibiting localized corrosion, such as pitting and crevice corrosion (Figure 4).

Environmentally friendly inhibitors such as some biomass wastes, amino acids, and ionic liquids have been investigated.

It is critical to choose the right corrosion inhibitor based on environmental conditions (temperature, pressure, and type of metal to be protected) and to ensure that the right amount is applied for maximum protection. The corrosion progress should also be monitored periodically to adjust the dosage

in several steps, including drilling, production, transportation, and storage of oil and gas. They can mitigate different types of corrosion in the petroleum industry, such as generalized corrosion, pitting corrosion, erosion corrosion, stress corrosion, galvanic corrosion, cavitation corrosion, and
236:: These polymers are used as corrosion inhibitors in the industry due to their good adsorption capacity on metal surfaces and their high solubility in oil and drilling fluids. They offer protection against the corrosive effects of hydrogen sulfide (H2S) present in the drilling fluid. (Figure 6).

Anodic inhibitors and cathodic inhibitors are the two main categories of corrosion inhibitors. While cathodic inhibitors act as catalysts to slow down corrosion, anodic inhibitors protect metal surfaces by acting as physical barriers. They can also be divided into organic and inorganic corrosion

d and citric acid are used as corrosion inhibitors. These acids react with metal ions to form insoluble compounds that protect the metal surface. These inhibitors are often used in combination with other corrosion inhibitors and techniques, such as cathodic protection and coatings, to provide
218:: Polymers are large molecules used in the petroleum industry as corrosion inhibitors. These polymers can adsorb onto the metal surface and form a protective coating. They can also be used as dispersants to prevent the formation of corrosive deposits. Some examples are:

comprehensive corrosion protection. CO2 and H2S are regularly seen in oilfields and are notorious for causing corrosion of metal sections. Fortunately, they can be kept under control with measures that have been found to be effective (Figure 3).
230:: These polymers are used as corrosion inhibitors in the industry due to their good compatibility with oil and drilling fluids. They are effective against corrosion caused by the presence of hydrochloric acid (HCl) in drilling fluids.
120:: These are imidazole-based compounds, usually with a long unsaturated chain length, derived mainly from oleic acid. They are very effective in preventing acid corrosion of carbon steel (Figure 1).
