Frequency response data from sinusoidal pressure experiments using liquids can be used to characterize the porous medium and its fluid properties. This paper examines the theory and presents correlations to help design experiments. Experiments were designed to check the theory. Measurements were made using a synthetic oil in an unconsolidated medium. Equipment was designed to generate pressure sine waves whose upper frequency limit was in excess of 1,000 rad/s. The theory indicates that there are definite frequency limits which may be used if the equations are to adequately describe the data. As the frequency and/or permeability increases, the inertial terms become important. This study shows that practical use can be made of existing theory to increase our ability to describe the flow of fluids in porous media.
