A process for preparing a hydrocarbon fluid includes a step of oligomerising an initial hydrocarbon composition which contains, in relation to the total weight of said initial hydrocarbon composition, at least 2% by weight of 3-methyl-but-1-ene, at least 5% by weight of 2-methyl-but-2-ene and at least 5% by weight of 2-methyl-but-1-ene. |
