Abstract: A crude oil is upgraded by thermal treatment at a temperature of at least 400.degree. C. under at least autogenous pressure and preferably from 100 to 1000 psig for about 20 to 30 minutes in order to increase the proportion of distillable components in the crude.

The process reduces the nondistillable residue and enables subsequent processing to be carried out with lower gas and coke make. The process may be operated with a whole crude or a topped crude as feed.
