ABSTRACT: Great efforts had been made to use indirect non-destructive tests in the geotechnical evaluation of rocks, especially sandstones ... porosity (n), bulk density (ρ), and ultrasonic P-wave ...

This is observed for fractures of both aspect ratios investigated here. EWAVE and MTEX-GassDEM models are used to calculate the fractured rock P-wave velocity. A key difference between the model is ...

Abstract: For oil and gas seismic exploration, rock velocities are essential parameters to ... Our 2D-3C FEM results show good agreement with experimental waveforms both in P- and S-wave velocity ...

To address the ill-posedness, in both the forward modeling and inversion, we introduce rock-physics constraints of frequency-independent S-wave velocity and limited variations of P-wave velocity with ...

1.Denser the materials higher are the velocity of earthquake waves. 2.P and S waves are types of surface ... Body waves interact with the surface rocks and generate new set of waves called surface ...
