Abstract

This invention refers to a process as well as to the equipment required to enhance the recovery of petroleum from onshore and offshore reservoirs. The pro-cess includes the simultaneous stimulation of the forma-tion by means of elastic sound waves, created by a sonic source installed at the oil well so that the elastic sonic waves which are superimposed reduce the adherence forces in the layer between oil/water and the rock forma-tion, and by means of the oscillating electrical stimula-tion of the same layer, as from the same wells subject to sonic treatment, where the electricity heats the formation by means of resistive heating, and thus increases the pressure, eliminating, thus, the surface tensions between the faces of the fluid as a consequence of the oscillatory action of the ions in the surfaces of the fluid and, in addition, reducing the viscosity of the fluids. The pro-cess is achieved as the petroleum is produced in the wells thus treated, and the flow of petroleum acts then as a cooling agent which removes the heat released by the well area and thus allows a larger input of energy than in any other method known so far.
