There is described a process for the stimulation of an oil reservoir or an oil well for enhanced oil recovery and/or seismic mapping of the reservoir, wherein a sound source is used. This sound source is operated by pressurized oil from the oil well by a hydraulic power unit at the surface, and the oil is conducted to an accumulator located in the sound source via a supply line.

[ What is claimed is:] [1.]1. A process for stimulating oil recovery in an oil well having a lower end and an upper end, the well comprising a housing with a sound source and oil accumulator at the lower end of the well, the process comprising steps of:using a hydraulic power unit to provide pressurized oil to the oil accumulator via a supply line;operating the sound source with said pressurized oil;expelling the pressurized oil back to the well;opening a valve when oil pressure in the accumulator reaches a certain level;providing pressurized oil to an upper side of a piston, thereby pressing the pistonand a plunger downward;striking an expansion pipe with the plunger, the resulting sound waves creating a pressure peak that reverses the direction of the valve; andproviding oil from an underside of the piston, thereby lifting the piston and plunger back to their previous position.
