Title (EN) PROCESS FOR INCREASING THE DEGREE OF OIL EXTRACTION
(FR) PROCEDE PERMETTANT D'AUGMENTER LE DEGRE D'EXTRACTION DU PETROLE
Abstract:
(EN) A process for increasing the degree of extraction of oil or other volatile liquids in oil reservoirs on land or at sea, by making the formations in said reservoir vibrate as close to the natural frequency of said formations as possible, so that the binding forces between formations and oil are degraded and oil is, thus more easily recovered from the formations. Furthermore, the pressure in said reservoir is maintained by evaporating some oil and water in the reservoir, due to the fact that heating is achieved both as a consequence of said vibrations, and by the aid of electrical high frequency pulses causing the reservoir to perform like an electrode furnace.
(FR) Un procédé, destiné à augmenter le degré d'extraction du pétrole ou d'autres liquides volatiles dans des réservoirs de pétrole sur terre ou en mer, consiste à faire vibrer les formations présentes dans lesdits réservoirs à une fréquence aussi proche que possible de leur fréquence naturelle, de telle sorte que les forces de liaison entre les formations et le pétrole soient réduites et que celui-ci soit par conséquent extrait plus facilement desdites formations. En outre, la pression dans lesdits réservoirs est maintenue en évaporant une partie du pétrole et de l'eau contenus dans les réservoirs, puisque l'augmentation de la température est due d'une part à l'effet desdites vibrations et d'autre part à l'aide d'impulsions à haute fréquence électrique qui permettent aux réservoirs d'agir comme un four à électrodes.
