Seismic full-waveform inversion (FWI) is a nonlinear computational imaging technique that
can provide detailed estimates of subsurface geophysical properties. Solving the FWI …

Monitoring the rock physics properties of the subsurface is of great importance for reservoir
management. For either oil and gas applications or CO2 storage, seismic data are a …

Time-lapse 4D full-waveform inversion (FWI) is a valuable technology for high-resolution
imaging of reservoir changes caused by hydrocarbon production and CO 2 storage …

Time-lapse seismic, also known as 4D seismic, is a powerful tool for monitoring subsurface
changes over time. By comparing seismic data acquired at different intervals, it enables the …

Detecting and inverting the imprint of changing subsurface elastic parameters on seismic
data lies at the heart of time-lapse seismic imaging for reservoir monitoring. In this work we …

Hydrocarbon production modifies several lithological parameters of a reservoir, as P
velocity, density and electrical conductivity, which may have a dominant effect. Anelastic …

This thesis describes new interferometric imaging methods for migration and waveform
inversion. The key idea is to use reflection events from a known reference reflector to” …
