Abstract (en)

[origin: WO2018206881A1] The present invention relates to a composition comprising at least one polymer in which the repeating unit comprises at least one amide function, at least one polyetheramine having a molecular weight (MW) of more than 100 g.mol-1, and having at least two secondary and/or tertiary amine functions, and optionally, but preferably, at least one organic solvent. The invention also relates to the use of said composition for delaying, or even preventing, the formation of gas hydrates, in particular in a method for extracting crude oil and/or gas and/or condensates, as well as to the method for delaying or even preventing the formation and/or agglomeration of gas hydrates, using a composition as defined above.
