At the recent IMAGE ’24 conference in Houston, full waveform inversion (FWI) was once again a hot topic. Notably, there was more focus on the inversion of elastic properties.
It was great to see Shell and Chevron showcasing the benefits of multi-parameter elastic FWI. Read about their work below:

Also at IMAGE ’24, BP presented papers on the limits of single-parameter FWI with respect to amplitude analysis, highlighting the importance of multi-parameter inversions to resolve crosstalk.

We were also at IMAGE ’24 where we launched our elastic MP-FWI imaging solution!
Our new elastic MP-FWI imaging technology solves for reflectivity, Vp, Vs, P-impedance, S-impedance and density. It delivers unsurpassed imaging along with elastic rock properties for quantitative interpretation and pre-stack amplitude analysis — directly from field-data input!
When using the full wavefield for simultaneous velocity model building and true-amplitude imaging a multi-parameter inversion is a necessity. A single-parameter FWI cannot separate velocity and reflectivity with validity.
