Abstract

Summary

Full waveform inversion (FWI) produces high-resolution earth models, the use of which can improve seismic imaging. FWI can also help create absolute inversion products, by filling the low frequency spectral gap in the integration with amplitude seismic data. However, what frequency should be used for FWI to cost-effectively estimate absolute elastic properties remains an open question. We present analysis from a case study in the Norwegian Sea. Initially we demonstrate how imaging challenges have been overcome by the use of FWI and high-end imaging. Following this, we reveal there is a cost-benefit sweet-spot for the low frequency models from FWI and broadband seismic amplitude data in the generation of absolute seismic inversion products.
