Advanced vibroseismic technique for water flooded reservoir stimulation, mechanism and field tests results

Theoretical and experimental studies show significant changes in flow properties of water-oil and water-oil- gas systems within the field of elastic vibrations. It results in multiple acceleration of the gravity segregation, increase of gas saturation of the reservoir fluids, rate and efficiency of capillar displacement as weIl as enhancement of the oil displacement by water. Newly designed technology of vibroseismic stimulation incorporating surface energy sources has been successfully tested in two depleted oil fields being at the late stage of waterflooding.
