Forward and inverse modelling in geophysics
WebFWI is commonly formulated as an iterative process that seeks to improve the model by minimizing the differences between the synthetic traces obtained using a reference model (which can be poor in high-frequency content) with the real seismic trace recorded experimentally, hereafter referred to as “data”, by means of a cost functional. WebThe model is used to simulate geoelectric targets in mineral exploration and to test a procedure to obtain current source terms by inverting an SP data set. Data inversion is …
