A bitumen is rendered pipelineable by partially hydroconverting the bitumen and then adding sufficient diluent to the partially hydroconverted bitumen to provide a mixture having an API gravity at 15.degree. C. of at least 19.degree. and a viscosity at 40.degree. C. in the range of about 35 to about 60 cP.
[ What is claimed is:] [1.] A method for rendering a heavy hydrocarbon pipelineable using reduced amounts of diluent which comprises:subjecting the hydrocarbon to hydroconversion under conditions and for a time sufficient to provide a product oil having a viscosity in the range of about 60to 250 cP at 40.degree. C.; and,adding a diluent to the product oil in an amount sufficient to provide a mixture having an API gravity at 15.degree. C. of at least about 19.degree. and a viscosity of about 40 to about 50 cP at 40.degree. C. whereby reduced amounts of di...
