Title (EN) APPARATUS AND METHODS FOR ENHANCING PETROLEUM EXTRACTION
(FR) APPAREIL ET PROCÉDÉS D'AMÉLIORATION DE L'EXTRACTION DE PÉTROLE
Abstract:
(EN) An apparatus and method for enhancing the extraction of hydrocarbons from an underground reservoir using a well is disclosed. The apparatus comprises a power source operable to supply periodic electrical power at a first frequency; at least one impulse generator unit operable to convert the periodic electrical power at the first frequency into periodic electrical power at a second frequency and to couple electromagnetic energy generated by the periodic electrical power at the second frequency into the reservoir, the second frequency being at least ten times higher than that of the first frequency; and a conducting cable being operatively coupled between the power source and the at least one impulse generator unit.
(FR) L'invention concerne un appareil et un procédé d'amélioration de l'extraction d'hydrocarbures d'un réservoir souterrain au moyen d'un puits. L'appareil comprend une source de puissance conçue pour une alimentation en puissance électrique périodique à une première fréquence ; au moins une unité de générateur d'impulsions conçue pour convertir la puissance électrique périodique à une première fréquence en puissance électrique périodique à une seconde fréquence et pour coupler l'énergie électromagnétique générée par la puissance électrique périodique à la seconde fréquence dans le réservoir, la seconde fréquence étant au moins dix fois supérieure à la première fréquence ; et un câble conducteur couplé de manière fonctionnelle entre la source de puissance et ladite au moins une unité de générateur d'impulsions.
