ABSTRACT OF THE DISCLOSURE A process for upgrading heavy crude comprises the hydroconversion of asphaltenes and resins in the presence of steam and ammonia at high temperatures, followed by deasphalting to eliminate metals and remaining asphaltenes. By way of the process of the present invention, conversion of asphaltenes and resins is accomplished while at the same time insuring a low formation of gases and coke so as to obtain an end product with a high yield of distillates and low metal content. The process is particularly suitable for any type of heavy crude, for example those of the Orinoco zone, which possess a high content of asphaltenes and metals.
