Bayesian Variational Time-lapse Full-waveform Inversion
Xin Zhang, Andrew Curtis
Time-lapse seismic full-waveform inversion (FWI) provides estimates of dynamic changes in the subsurface by performing multiple seismic surveys at different times. Since FWI proble…
Variational Bayesian experimental design for geophysical applications: seismic source location, amplitude versus offset inversion, and estimating CO2 saturations in a subsurface reservoir
Dominik Strutz, Andrew Curtis
This paper introduces variational design methods that are novel to Geophysics, and discusses their benefits and limitations in the context of geophysical applications and more esta…
Travel times and ray paths for acoustic and elastic waves in generally anisotropic media
James Ludlam, Katherine Tant, Victorita Dolean +1
Wavefield travel time tomography is used for a variety of purposes in acoustics, geophysics and non-destructive testing. Since the problem is non-linear, assessing uncertainty in t…
Introducing Conceptual Geological Information into Bayesian Tomographic Imaging
Hugo Bloem, Andrew Curtis, Daniel Tetzlaff
Geological process models simulate a range of dynamic processes to evolve a base topography into a final 2D cross-section or 3D geological scenario. In principle, process parameter…
3D Bayesian Variational Full Waveform Inversion
Xin Zhang, Angus Lomas, Muhong Zhou +2
Seismic full-waveform inversion (FWI) provides high resolution images of the subsurface by exploiting information in the recorded seismic waveforms. This is achieved by solving a h…
Interrogating probabilistic inversion results for subsurface structural information
Xin Zhang, Andrew Curtis
The goal of a scientific investigation is to find answers to specific questions. In geosciences this is typically achieved by solving an inference or inverse problem and interpreti…
