1: Asphalt inhibitor

Description

Asphaltene deposition in oil reservoirs is one of the most important problems in the production of reservoirs. Obstruction in the porous environment of the oil formation, wellhead and processing facilities are serious problems in the production of asphaltene oils. Asphaltines are generally heavy compounds found in oil. This compound has a complex molecular structure that can be described as a set of non-hydrocarbon molecules soluble in benzene and insoluble in low molecular weight solvents as well as normal alkanes. According to several laboratory studies, these compounds are thought to be dissolved in colloidal form in oil. Sediment formation factors in reservoirs are changes in pressure, temperature and oil composition. These factors upset the chemical balance in the reservoir, which results in the formation of sediment. Therefore, it is valuable to explore possible ways to prevent asphaltene deposition. One possible way to prevent asphaltene build-up is to add asphaltene stabilizers to the oil as a repellent. Asphaltene inhibitors act like resins, converting asphaltenes to colloids and keeping them in solution. The effectiveness of a inhibitor depends largely on its structural and chemical properties. The inhibitory ability to stabilize asphaltenes also depends on the solvent and dispersion medium.
