Asphaltene Aggregation and Deposition in Porous Micromodel [PDF]

, 2015
Asphaltene deposition is a common cause of flow assurance problems in wellbores and production equipment as well as near-wellbore regions in oil reservoirs. Therefore, understanding the mechanism by which asphaltenes deposit onto solid surfaces is highly
