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.]1. A pipelineable mixture comprising:a major amount of an oil obtained by subjecting a heavy hydrocarbon to hydroconversion under conditions and for a time sufficient to provide the oil with a viscosity at 40.degree. C. in the range of 60 to 250 cP and an API gravity at 15.degree. C. in the range of about 15.degree. to 17.degree. and a diluent selected from the group consisting of naphtha and natural gas condensates in an amount sufficient to provide the mixture of oil and diluent with an API gravity at 15.degree. C. of at leas...
