ABSTRACT:
The invention concerns a process for reducing the tendency of hydrates in a fluid comprising at least water, a gas and a paraffin oil to agglomerate, by addition of a mixture of at least two organosoluble additives, namely at least one polyisobutene-polyethyleneglycol block copolymer and at least one copolymer of an alkyl (meth)acrylate and a nitrogen-containing monomer. These organosoluble copolymers are generally introduced at an overall concentration of 0.05% to 5% by weight with respect to the water present in the medium.
