This patent describes a process for converting a metals-contaminated heavy crude oil characterized by an API gravity less than about 20{degrees} and a substantial Conradson Carbon Residue to a pipelineable and substantially upgraded syncrude with concomitant recovery of blown asphalt. It comprises: air-blowing at least the 650{degrees} F.{sup +} fraction of the heavy crude oil at a temperature of 390{degrees} to 600{degrees} F. under conditions effective to increase its combined oxygen content by at least 0.5 weight percent; deasphalting the air-blown crude oil with solvent whereby separately recovering a blown asphalt and an intermediate syncrude having a substantially lower concentration of metals and less Conradson Carbon residue than the heavy crude oil; and, visbreaking the intermediate syncrude at 800{degrees} to 950{degrees} F. and at a severity effective to impart to it pipelineable viscosity characteristics.
