... wave and dipole S-wave are sensitive to fractures filled with fluid, manifested as energy attenuation. It suggests that both of these two types of mode wave can be used to identify and evaluate fractures near well. Furthermore, Stoneley wave is not sensitive to the fracture filled with calcite, while...

... Digital rock physics is an image-based computational technique used to study the physical properties of rocks. Digital rock studies originated in sandstones, which are quartz-dominated rocks with varying amounts of feldspar, calcite, and clay. However, there are significant differences...

... ABSTRACT Describing physical properties of reservoir rocks is of great interest. Lab testing can be expensive, and may not have the desired spatial sampling for long cores. Here, we describe a hand sample of a carbonate rock comprised of calcite and dolomite. We use digital rock physics...
