Tetramethyl ammonium chloride has various uses and effects in the oil field extraction industry. The followings are several main aspects:
Inhibition of hydrate formation: During oilfield extraction, contact between groundwater and extracted crude oil can lead to hydrate formation, including mineralization and hydrated asphaltene. These hydrates can clog oil wells and pipelines, reducing oilfield production efficiency. Tetramethyl ammonium chloride can be used as an additive to control and inhibit the formation of hydrates, in order to reduce blockage problems.
Preventing sediment formation: In oilfield development, changes in reservoir temperature and pressure are often accompanied. These changes may lead to the accumulation of mineral salt deposits (such as sulfates and carbonates) on the surface of oil wells and pipelines. Tetramethylammonium chloride can be used as a scale inhibitor to prevent the formation of these deposits, maintain equipment smoothness and operational efficiency.
Reduce surface tension: There is interfacial tension between oil and water in oil wells, which limits oil flow and collection efficiency. TMAC has the properties of a surfactant, which can reduce the tension of the oil-water interface, promote the flow and collection of oil.
Improving oil recovery efficiency: Tetramethyl ammonium chloride can also be used as an oil displacement agent to improve the oil recovery efficiency of the oilfield. Injecting a solution containing Tetramethyl ammonium chloride into the reservoir can improve the fluidity of crude oil, reduce viscosity, and increase recovery rate.

Tetramethyl ammonium chloride, TMAC, easily soluble in water and alcohols, belongs to Quaternary ammonium compounds. It has a lot of applications in many fields, the following mainly introduces one of the most important functions of Tetramethyl ammonium chloride in oilfield exploitation.
Tetramethylammonium chloride is widely used as a shale inhibitor in oilfield exploitation. The clay content in shale is high. When water-based drilling fluid comes into contact with shale, it can cause clay to expand and disperse, leading to wellbore collapse. Shale swelling and dispersion when encountering water are caused by the dissociation and hydration of exchangeable cations on the surface of shale in water, forming a diffusion double layer with negative charge and generating electrostatic repulsion. Therefore, drilling fluid should have two major functions-preventing or delaying water migration from the wellbore to the wellbore, and increasing the connectivity between mineral particles on the wellbore. Cationic surfactants can produce surface active cations after dissociation in water, which can adsorb on the clay surface, neutralize the negative charge on the clay surface, and inhibit shale expansion and dispersion, thereby stabilizing the wellbore.
