First Claim
Patent Images
1. A method of stimulation of near well zone by vibration comprising the steps of:
- arranging a vibration sensor in the vicinity of a productive layer of the active well;
measuring the eigen frequency bandwidth of filtration process for each sublayer of the productive layer using the vibration sensor by means of movement of the vibration sensor up and down along the productive layer;
providing a source of vibration installed in the region of the productive layer/sublayer said vibration sensor is located in the vicinity of the source of vibration generating vibrations on a frequency bandwidth corresponding to the eigen frequency bandwidth of the productive layer, said vibration sensor measures the frequency of said vibration source for adjusting a frequency bandwidth of said vibration source to the said eigen frequency bandwidth of the said productive layer.

Abstract
A process is provided to enhance fluid production, recovery, and/or injection from and/or into fluid-bearing formations. The process includes the stimulation of the formation by vibrations, generated by the vibration source installed in the vicinity of the productive layer so that the stimulation is performed on the frequency coinciding with the eigen frequency bandwidth of filtration process of productive layer/sublayer.
