Definition - What does Inhibition mean?
Inhibition is the process of slowing down, preventing or stopping any process or reaction that may harm the equipment or overall efficiency of the oil and gas setup. There are various inhibition processes that help the industry to operate effectively at optimized levels. These processes include corrosion inhibition process which is done with the help of corrosion inhibitors and inhibitive mud system which slows down the hydration or swelling of clay and shale.
Petropedia explains Inhibition
Inhibition is usually done in the production process so as to avert any accident or situations that may affect the efficiency of the entire process. A good reason for performing inhibition process is to control corrosion of the inner and outer surfaces of the equipment in refineries because of high chemical oxidation reactions that take place during the refining of crude oil.
Such corrosion controlling tools are called corrosion inhibitors, which when added to an environment in small concentrations, effectively reduces the corrosion rate of a metal exposed to that environment. There are three types of corrosion inhibitors, i.e., anodic inhibitors, cathodic inhibitors and mixed inhibitors.
Similarly, Inhibitive mud is used along with the drilling fluids to stop or slow down the swelling or disintegration of clay and shale during directional drilling process.
