removal of asphaltene deposition from well columns: impact of casing composition

The oil industry is at risk from asphaltene deposition in oil reservoirs and wells as well as in oil transportation and refineries. as a result, it would be of practical implication to discern its impact by implementing cutting-edge operational methods. the goal of the current study is to investigate how the casing material affects the threshold at which asphaltene may be removed from the well column using the shear force, rolling, and rebound processes. in order to show how the surface material would be practical in asphaltene abatement, the experimental size distribution of asphaltene particles and the theory of surface energy are used. the findings demonstrated that the casing substrate profoundly affects the critical velocities of asphaltene removal from the well column, where particle rebound played a decisive effect.
