... or the fracture plane may be tilted from the borehole axis. A 3D finite-difference time domain (FDTD) formulation of equations of motion for elastic waves in such fractured formations has been used to calculate synthetic waveforms at an array of receivers in a liquid-filled borehole. The synthetic waveforms...

... SUMMARY We present a novel FD scheme which can solve accurately elastic wave propagation in the presence of topography in 3D. It is based upon a Fully Staggered Grid and employs grid deformation and mimetic operators to obtain results with very few points per wavelength when compared to other...

... SUMMARY A perturbation method for elastic waves and numerical forward modeling are used to calculate the effects of seismic wave scattering from arbitrary shape shallow subsurface heterogeneities. Wave propagation is simulated using elastic finite difference for several earth models...

... Summary A recent advance in single-well reflection imaging is the utilization of a dipole acoustic system in a borehole to radiate and receive elastic waves to and from a remote geological reflector in formation. This paper substantiates this dipole-acoustic imaging technology by numerically...

In this study, we calculated the incident angle for each receiver using tangential angles, one of which using amplitudes of acquired three component data and the other using tau-P transform. After the comparison, we used the latter considering...
