Process to optimize the yield of gas oils from a Fischer-Tropsch derived feed by performing the following steps: (a) performing a hydroconversion/hydroisomerisation step on part of the Fischer-Tropsch derived feed; (b) performing a hydroconversion/hydroisomerisation step on another part of the Fischer-Tropsch feed at a conversion greater than the conversion in step (a); and (c) isolating by means of distillation a gas oil fraction from the two reaction products obtained in steps (a) and (b).
