A process for upgrading heavy oils and bitumen to a crude oil with properties acceptable as a refinery feedstock includes the steps of solvent de-asphalting by separating the polynuclear aromatics including asphaltenes from the heavy oil or bitumen and contacting the de-asphalted oil with biological and chemical reagents to reduce the concentrations of contaminants so as to render the resulting oil an acceptable feedstock for petroleum refineries.

Procédé de valorisation d'huiles lourdes et de bitume en pétrole brut ayant des propriétés acceptables comme un produit d'alimentation de raffinerie, qui consiste à désasphalter le solvant de désasphaltage par séparation des composés aromatiques polynucléaires comprenant des asphaltènes à partir de l'huile lourde ou du bitume et à mettre en contact l'huile désasphaltée avec les réactifs biologiques et chimiques pour réduire les concentrations de contaminants de manière à transformer l'huile obtenue en une charge acceptable pour les raffineries de pétrole.
