DLP Webinar with René-Edouard Plessix
Visco-Acoustic Full Waveform Inversion
|Wednesday 8 November 2017 - 10.00 AM (CET)|
|1 hour lecture + 30 minutes Q&A|
|Free for EAGE members|
|Computer with Internet connection and audio/video capabilities|
EAGE webinars are live presentations with lecturers selected from the best presentations at EAGE Conferences. After the lecture, participants can interact with the instructor and ask questions. Joining a webinar is simple: all you need is a computer with Internet connection and audio/video capabilities (no software installation required). This service is complimentary for EAGE members and places are limited.
After a briefly introduction on seismic attenuation and dispersion, I review a time-domain implementation of the visco-acoustic wave equation. I also briefly describe the inversion approach based on the adjoint state technique. With the help of a synthetic study, I then describe the advantages and issues we encounter when inverting for both velocity and quality factor. This synthetic study illustrates the trade-off between velocity and quality factor through sequential and simultaneous inversions. I finally present a visco-acoustic full waveform inversion on a data set recorded offshore Malaysia where gas pockets are presented in the sub-surface.
