Obtaining interval velocities using an adaptive hybrid inversion multiscale approach
Rodrigo de S. Santos, Milton José Porsani · 2017
The understanding of the interior of the planet through the seismic method requires the mapping of the velocities with which the elastic waves propagate. The main objective of this work is the development of improved techniques to obtain interval velocities in time, by inversion of RMS velocities. In this article, the data inversion is performed with a combination of local and global optimization methods. In order to reduce the problems related to the large number of inversion parameters, a multiscale approach will be presented in the parameter domain. The proposed method is tested in subdetermined problems and with addition of noise. The results shown in the M3 model simulate how this methodology it can be applied applied to real data, which raises the relevance of this research.
