Summary:
Study of acoustic noise induced by fluid flow in porous media is a relatively new area of research. Special attention to this topic is motivated by the growing interest of oil and gas companies to develop new production control techniques with focus on analysis of flow dynamics in the reservoir. A set of approaches and setup designs was suggested by different research groups for laboratory measurements of the acoustic noise in rock samples but a generally accepted procedure for such measurement is still under discussion. In the paper, we discuss new design of experimental setup. Experimental results with several types of carbonate rocks and sandstones are provided. Analysis of noise signal intensity as a function of flow rate shows that acoustic noise signal in rock samples appears only when the Forchheimer number exceeds values in the range 0.1-0.3. Indiana Limestone samples generate noise within the frequency range from 2 to 30 kHz. Noise in Buffalo Berea sandstone significantly differs from that in the Limestone samples and occurs in the frequency range from 1 to 5 kHz. The heterogeneous rocks are more prone to noise generation than sandstones.
