Into the details

This page is under development Our main research areas are seismic modeling, wave equation migration velocity analysis (WEMVA) and full waveform inversion (FWI). In this page we give short introductions to the different areas. To make the text easy to read, and not require too much background knowledge, the most technical details are leaved out.

Seismic modeling

Wave Equation Migration Velocity Analysis (WEMVA)

Full Waveform Inversion (FWI)

Example

Below is the result of estimating the velocity model from synthetic data using Wave equation Migration Velocity Analysis (WEMVA) based on reverse-time migration (right). The true velocity model is displayed on the left.

 Best velocity model using WEMVA  True velocity model

The image below shows the result of Full-Waveform Inversion (FWI) using the WEMVA velocity model as an initial guess.
