Process for reducing the viscosity of a highly viscous hydrocarbon charge containing 10-30% b.w. of constituents distilling above 375/sup 0/ C., said treatment comprising hydrovisbreaking said charge to such an extent as to convert 10 to 30% of the 375/sup 0/ C. /sup +/ fraction to a 375/sup 0/ C. /sup -/ fraction, fractionating the hydrovisbreaked product to separate a fraction comprising at least 90% of the constituents boiling below 375/sup 0/ C. from a distillation residue, deasphalting said distillation residue and admixing at least a portion of the deasphalted distillation residue with at least a portion of said fraction comprising at least 90% of the constituents boiling below 375/sup 0/ C.
