Zusammenfassung:Methods and compositions for hindering asphaltene deposition. One method comprising: identifying an interval of the subterranean formation to be treated with a relative permeability modifier to hinder subsequent asphaltene deposition; introducing the relative permeability modifier into the subterranean formation; and allowing the relative permeability modifier to contact the interval, thereby attaching to surfaces within the subterranean formation and hindering subsequent asphaltene deposition.
