Title
(EN) METHOD OF REDUCING THE VISCOSITY OF HYDROCARBON FLUIDS
(FR) PROCÉDÉ DE RÉDUCTION DE LA VISCOSITÉ DE FLUIDES D'HYDROCARBURE
Abstract
(EN)
A method for reducing the viscosity of a hydrocarbon fluid encountered in petroleum operations is disclosed. The method includes contacting the hydrocarbon fluid with an effective amount of a composition comprising at least one polymer having at least 25 mole percent cationic monomers.
(FR)
L'invention concerne un procédé de réduction de la viscosité d'un fluide d'hydrocarbure associé à des opérations pétrolifères. Le procédé comprend le fait de mettre en contact le fluide d'hydrocarbure avec une quantité efficace d'une composition comprenant au moins un polymère contenant au moins 25 pour cent en moles de monomères cationiques.
