How is seismic data recorded
Web13 apr. 2024 · ABSTRACT P/S-wave separation is a key step for data processing in multicomponent seismic exploration. The conventional methods rely on either the prior information of near-surface elastic properties or the carefully selected parameters to estimate the polarization directions of the P- and S-modes when arriving at the … Web12 nov. 2024 · The seismic reflection method provides the highest resolution images of the structure of the crust and Moho. There are two reasons for this. The first reason is that this method uses densely recorded data from closely spaced shots and seismic recorders (geophones). The second reason is that the seismic reflection method uses high …

WebSeismic exploration of the Earth has a long history, dating back almost 200 years. Working by generating propagating waves of alternating pressure that cause localized regions of compression and rarefaction, the seismic method is dependent upon the elastic properties of the host medium. WebSeismic data have the potential to provide the bridge between well logs and core analysis on the one hand, and tracer and well-test analysis on the other. Most …
