1. A method for at least partially removing catalyst fines from a heavy oil containing them, the method comprising:
introducing an additive into the heavy oil containing catalyst fines in an effective amount to at least partially remove the catalyst fines, where the additive is selected from the group consisting of:
an oxyalkylated acid-catalyzed alkylphenol formaldehyde resin;
a Mannich condensate base resin copolymer; and
combinations thereof; and
at least partially removing the catalyst fines from the heavy oil by a physical process.
