A process for treating a raw material, consisting of a well stream comprising crude oil and natural gas, or of a stream of non-stabilised crude oil, for storage/transportation of a stabilised crude oil and a stabilized gas product in separate tanks. Gaseous and volatile components are separated from the raw material and are contacted with water under hydrate-forming pressure and temperature conditions in a hydration zone to produce a hydrate mass. Said mass is cooled down to a final temperature lower than the freezing point of water, to form a liquid gas hydrate-containing hydrocarbon product comprising particles of gas hydrate suspended in a hydrocarbon-containing liquid supplied during the production or cooling of the hydrate mass.
