1. A process for upgrading heavy oil or bitumen to formulate synthetic hydrocarbons, comprising:

  • (a) providing a source of heavy oil or bitumen feedstock;

    (b) treating said feedstock to form one or more distilled fractions and a non-distilled bottom fraction;

    (c) feeding said bottom fraction to a syngas generating circuit to generate a hydrogen lean syngas stream via a non-catalytic partial oxidation reaction, wherein said hydrogen lean syngas stream has a hydrogen to carbon monoxide ratio of less than one part hydrogen to one part carbon monoxide;

    (d) adding an external source of hydrogen to said hydrogen lean syngas to generate a hydrogen rich syngas stream optimum for Fischer-Tropsch reaction; and

    (e) reacting said hydrogen rich syngas stream in a Fischer-Tropsch reactor to formulate said synthetic hydrocarbons, at least one of which is synthetic crude oil.
