PCT No. PCT/NO86/00080 Sec. 371 Date Jul. 8, 1987 Sec. 102(e) Date Jul. 8, 1987 PCT Filed Dec. 3, 1986 PCT Pub. No. WO87/03643 PCT Pub. Date Jun. 18, 1987.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 frequeny pulses causing the reservoir to perform like an electrode furnace.
