Abstract
A process is described for retarding or inhibiting the growth and/or aggregation of hydrates in production effluents comprising water and a gas under thermodynamic conditions in which hydrates can form, characterized in that a low concentration (0.05% to 5% by weight with respect to the water) of water-soluble copolymer containing hydrophobic groups is incorporated into the effluent.
