Abstract
The processes of asphaltene precipitation are specific due to the heterogeneity of the oil reservoir system and the non-stationary nature of the ongoing processes. Therefore, to design technologies for injecting solvents into an oil reservoir in order to increase oil recovery, detailed and comprehensive studies of the colloidal stability of petroleum dispersed systems are required. An important task is the selection of the optimal formulation and composition of inhibitors, the use of which would ensure a reduction in asphaltene precipitation and an increase in the stability of the dispersed oil system of each individual well planned for the implementation of the technology.
The work provides a review of the asphaltene inhibitors used. It has been established that despite the large number of works devoted to the selection of inhibitors that prevent the process of deposition of high molecular weight hydrocarbon deposits, there is no methodology for selecting inhibitors for each potential object of implementation, and therefore this is a promising area for research. The use of spectrophotometry makes it possible to accurately assess the ability of inhibitors to keep asphaltene clusters or aggregates in suspension and not precipitate from solution. This method can be used to select the type of inhibitors.
