| 1. A process for the production of a pipeline-transportable crude oil from a bitumen feed, the process comprising;
(1) dividing the bitumen feed into two fractions, the first fraction comprising between 20 and 80 wt % of the feed, the second
fraction comprising between 80 and 20 wt % of the total feed, the two fractions together forming 100 wt % of the feed;
(2) distilling of the first fraction obtained in step (1) into a light fraction boiling below 380° C. and a residual fraction;
(3) thermal cracking of at least part of the residual fraction obtained in the distillation process described in step (2);
(4) distilling of the product obtained in step (3) into one or more light fraction(s) boiling below 350° C., optionally one or more intermediate fractions boiling between
350 and 510° C. and a heavy fraction boiling above at least 350° C.;
(5) combining the second fraction obtained in step (1), the light fraction obtained in step (2) and the light fraction(s) obtained in step (4) to obtain a pipeline-transportable crude oil; and,
(6) using the heavy fraction obtained in step (4) for the generation of power and/or heat.
