Title (EN) TUBULAR PROTECTION FOR RADIOFREQUENCY SYSTEM TO IMPROVE THE RECOVERY OF HEAVY OILS
(FR) PROTECTION TUBULAIRE POUR SYSTÈME RADIOFRÉQUENCE AFIN D'AMÉLIORER LA RÉCUPÉRATION D'HUILES LOURDES
Abstract:
(EN) The present invention relates to a system for facilitating the extraction of hydrocarbons, in particular a tubular protection for an extraction system using the RF heating of highly viscous hydrocarbons in situ by means of an antenna having a coaxial array of mode converters.
(FR) La présente invention concerne un système pour faciliter l'extraction d'hydrocarbures, en particulier une protection tubulaire pour un système d'extraction à l'aide du chauffage RF d'hydrocarbures hautement visqueux in situ au moyen d'une antenne ayant un réseau coaxial de convertisseurs de mode.
