ABSTRACT OF THE DISCLOSURE Heavy crude oils unsuitable for pipelining without addition of solvent or cutter stock are upgraded by a mild thermal treatment which is more severe than conventional visbreaking but less severe than delayed coking, followed by a mild, solvent- deasphalting step. The mild solvent-deasphalting is effective in rejecting a major fraction of the metals and Conradson Carbon Residue of the crude, and directly produces a pipelineable syncrude of much better quality than the original crude for cracking and/or hydrocracking. The asphalt by-product is burned to produce process steam necessary for the production of the crude. The process described minimizes investment and operating cost, and is adaptable to skid-mounting for on-site operation.
