2017 SEISCOPE Presentation at SEG Houston
Since 2006, the SEISCOPE consortium has been in the forefront of research on Full Waveform Inversion (FWI) for high-resolution seismic imaging at exploration and crustal scales. We have developed new tools for seismic modeling and FWI both in the time and frequency domains, under finite difference and finite element approaches. We have performed many successful 2D and 3D real-data applications for multiple parameters FWI, under the acoustic, (…)
