On the modeling and inversion of seismic data

WebGiven the initial three-dimensional distribution of water saturation and porosity and a well-log derived height-saturation-porosity function as an inversion constraint, synthetic modeling suggests that time-lapse seismic data can potentially be directly inverted for the change in free water level, and time-lapse changes in the spatial variation of water saturation can … WebAs an important geophysical data processing technique, seismic inversion estimates subsurface rock properties with seismic observations. However, anisotropic inversion, …

LINEARIZED INVERSION OF SEISMIC REFLECTION DATA

WebAbstract: In order to investigate the velocity structure, and hence shed light on the related tectonics, across the Narmada–Son lineament, traveltimes of wide-angle seismic data along the 240km long Hirapur–Mandla profile in central India have been inverted. A blocky, laterally heterogeneous, three-layer velocity model down to a depth of 10km has been … WebSeismic inversion is a process to obtain the spatial structure and physical properties of underground rock formations using surface acquired seismic data, constrained by known geological laws and drilling and logging data. The principle of seismic inversion based on deep learning is to learn the mapping between seismic data and rock properties by … greetings for mothers birthday https://taffinc.org
