Abstract
In order to improve the transport of oilfield effluents comprising water, a gas and possibly a liquid hydrocarbon phase under thermodynamic conditions which can lead to the formation of hydrates, a formulation containing at least two additives, one of which behaves as a hydrate crystal nucleation agent, is added to the effluent to be transported.
