Technology plays a very important role in our modern life, and this is also true for the petroleum industry. As more and more oil fields are entering brown field operation the need for new mechanisms to increase the recovery is very high. A technique that is not well established is the stimulation with seismic waves. The positive impact of acoustic waves on subsurface fluid flow was first observed in water wells following an earthquake, but also noise generated by humans such as the passing of a railroad was observed to cause fluctuations in the water level in the wells. Therefore it was tried to utilize this positive effect as a stimulation method. A very important part of this thesis was to find out under which conditions the application of the aforementioned stimulation method showed positive results. This was achieved by looking into the past successful applications of such a technology and the extraction of the reservoir conditions under which it was performed. Furthermore, the possibility to use the acoustic wave stimulation as an alternative to conventional acid stimulation as a more environmentally friendly approach, or the probability to use both methods combined in order to increase the effectiveness, was discussed. Based on that starting point oil fields currently under RAG operation that, are meeting the requirements were selected. The rendered results of this process are used as a base for further considerations concerning the application of the stimulation method.
