Title
(EN) COMPOSITION THAT CAN BE USED TO DELAY THE FORMATION OF GAS HYDRATES
(FR) COMPOSITION PERMETTANT DE RETARDER LA FORMATION D'HYDRATES DE GAZ
Abstract
(EN)
The present invention relates to a composition comprising: at least one co-polymer of which at least one of the repeating units comprises at least one amide function; and at least one polyether having a molecular weight (M W) greater than 60 g.mol -1. 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 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.
(FR)
La présente invention concerne une composition comprenant au moins un co-polymère dont au moins un des motifs répétitifs comprend au moins une fonction amide, au moins un polyéther de poids moléculaire en poids (MW) supérieur à 60 g.mol-1. L'invention concerne également l'utilisation de ladite composition pour retarder, limiter voire empêcher, la formation d'hydrates de gaz, notamment dans un procédé d'extraction de pétrole et/ou de gaz et/ou de condensats, ainsi que le procédé pour retarder, limiter voire empêcher la formation et/ou l'agglomération d'hydrates de gaz, mettant en œuvre une composition telle que définie ci-dessus.
