Provided is a composition comprising at least one polymer, the repeat unit of which comprises at least one amide functional group, at least one polyetheramine with a weight-average molecular weight (M) of greater thang.mo1and exhibiting at least two secondary and/or tertiary amine functional groups, and optionally, but preferably, at least one organic solvent. Also provided is method of using of the composition for delaying, indeed even preventing, the formation of gas hydrates, in particular in a process for extracting oil and/or gas and/or condensates, and also to the process for delaying, indeed even preventing, the formation and/or the agglomeration of gas hydrates, employing a composition as defined above.

Composition which makes it possible to delay the formation of gas hydrates

Provided is a composition that includes (i) at least one compound represented by formula (I) as defined herein or a salt thereof and (ii) a nonionic surfactant. The composition is useful for limiting or preventing the formation and/or agglomeration of gas hydrates, by combining the composition and a production fluid that includes an aqueous phase and one or more gases.

Composition for limiting the formation and/or agglomeration of gas hydrates

Provided is a process for limiting or preventing the formation and/or agglomeration of gas hydrates, comprising combining (1) a production fluid comprising an aqueous phase and one or more gasses and (2) at least one compound represented by formula (I) or a salt thereof as defined herein.

Use of a particular carboxylic amino acid in order to limit the formation and/or agglomeration of gas hydrates

The subject-matter of the present invention is multifunctional corrosion inhibitors for protecting from top of line corrosion and bottom line corrosion for pipes used in particular in the petroleum industry. The corrosion-inhibiting compositions comprise, as inhibitors, at least one amine with a boiling point of between 105 and 130&#xb0; C.
