Carbonate reservoirs make up a significant part of the world's hydrocarbon potential. These rocks are characterized by the complexity of the structure of the void space, represented by cracks, pores, caverns. The cracks in carbonate rocks promotes the movement of fluid in the void space. Each type of voids has a specific effect on the elastic properties of rocks, which makes it possible to evaluate the characteristics of a certain type of voids from the measured velocities of elastic waves. The aim of this work is to increase the reliability of the interpretation of experimental data on the velocities of elastic waves propagating in carbonate reservoirs in terms of the characteristics of the void space, represented by pores and cracks.
