Workshop Description

Full Waveform Inversion has been a real breakthrough for velocity model building of complex structures. It also offers opportunities and perspectives in terms of automation and resolution of the velocity model building process. Its ability to deliver high resolution velocity models is maybe its most impressive aspect from a visual point of view. 

The trend to push for higher and higher resolution (or frequencies) is however now more and more questioned in terms of benefits for imaging and interpretation. It is also more and more recognized that these high resolution recovered features should be considered with care. Indeed, the corresponding physical parameters are coupled and not always correctly taken into account in the process (density, attenuation, anisotropy, elasticity, …). 

Despite these limitations there is a trend to use high resolution models obtained by FWI for interpretation purposes (Routh et al., 2017; Shen et al., 2018). 

The workshop will focus on the following questions:

• What is the use of a high resolution model? 
• How high is high? 
• Are there any benefits for interpretation? 
• Is better physics more important than high frequencies?
