... ABSTRACT Laboratory acoustic measurements are performed with Lucite fracture models to understand the reflection characteristics of a seismic wave in a fracture zone. The fracture models include single fracture, dual fracture, and fracture zones having different fracture geometries. First we...

Fracture modeling suggests that velocity anisotropy in conjunction with AVAZ (Amplitude variation with Angle and Azimuth) response should be utilized to understand fractured media. It is observed that as the number of fracture sets increases, critical angle moves towards...

.... However, incorporation of matrix elasticity for fluid-filled fracture model leads to the existence of slow Stoneley guided waves with distinct dispersive properties. Phase velocity and attenuation of these waves are described by simple formulas in a general case of a viscous fluid. Stoneley guided waves...

Here, through experiment studies in the laboratory with controlled fracture models and seismic physical modeling, we aim to investigate the effect of different fracture scale length and aperture on seismic properties...

... response to fractures Induction log response to hydraulic fractures have been studied by Anderson et al. (1996), Wang et al. (2001 and 2005), and Rabinovich et al. (2004). As in the previous studies, we model a hydraulic fracture with a wing-like fracture model (Figure 1). The fracture is assumed...
