JMI-FWI: Cascading Workflow Using Joint Migration Inversion (JMI) and Full Waveform Inversion (FWI)

Second EAGE/PESGB Workshop on Velocities, 2019
Summary Data driven Velocity Model Building (VMB) based on Full Waveform Inversion requires very broad band, especially low frequnecy data content to overcome the cycle skipping problem. In this paper we demonstrate how the Joint Migration Inversion method introduced by the DELHPI consortium group applied in a cascaded workflow to preduce a hich ...

Iterative direct waveform inversion (IDWI) plus Fourier-domain full waveform inversion (FWI)

2015 Workshop: Depth Model Building: Full-waveform Inversion, Beijing, China, 18-19 June 2015, 2015
Both full waveform inversion (FWI) and iterative direct waveform inversion (IDWI) were suggested for reconstruction of velocity model using seismic data. In FWI algorithm, the partial derivative wave field of parameter is used to define the amplitude of update.

Seismic Full Waveform Inversion (FWI) to characterise the structure of firn

2020
<p>The transformation of snow into ice is a fundamental process in glaciology. The yearly accumulation of fresh snowfall increases the overburden pressure, changing the snow’s properties such that it transitions into firn and pure glacier ice thereafter. Additionally, periods of melt and variations in subsurface and

Full-waveform inversion, Part 1: Forward modeling [PDF]

The Leading Edge, 2017
Since its reintroduction by Pratt (1999), full-waveform inversion (FWI) has gained a lot of attention in geophysical exploration because of its ability to build high-resolution velocity models more or less automatically in areas of complex geology. While
