Tile deasphalted oil can be exposed a first deasphalting process using a first solvent that can provide a lower severity of deasphalting and a second deasphalting process using a second solvent that can provide a higher seventy of deasphalting. This can result in forma- tion of at least a deasphalted oil and a resin fraction. The resin fraction can represent a fraction that traditionally would have been in - cluded as part of a deasphalter rock fraction.
