Three-dimensional numerical wave propagation in a digital core sample derived from three-dimensional X-ray tomography images


Abstract
To clarify the relationship between seismic attenuation phenomena observed in various seismic methods at widely different frequencies and fractures developed in carbonate reservoirs, we propose a novel method to measure dynamic properties of fractures in a broadband frequency by visualization of seismic wave propagation. The advantage of our proposed method over existing methods is that we can measure local properties of a core sample, which may enable us to obtain more reliable information about fractures than existing methods measuring the average properties of a core sample. In the present paper, we describe the concept and workflow of our proposed method. In the proposed workflow, the key technology is 3D numerical wave propagation in a digital core sample derived from 3D X-ray tomography images. We show our preliminary results and clarify technical challenges that need to be overcome to realize our proposed method.
