Controlled delivery and release of asphaltene inhibitors [PDF]

, 2019
Asphaltene is a poly-disperse distribution of the heaviest and most polarizable fraction of crude oil. The asphaltene aggregation and subsequent precipitation in nonpolar media may have a profound effect on plugging wellbores and production equipment ...
