A Physics-Based Neural-Network Way to Perform Seismic Full Waveform Inversion

open access: yesIEEE Access, 2020
Seismic full waveform inversion is a common technique that is used in the investigation of subsurface geology. Its classic implementation involves forward modeling of seismic wavefield based on a certain type of wave equation, which reflects the physics ...

Frequency Domain Full Waveform Inversion Method of Acquiring Rock Wave Velocity in Front of Tunnels

open access: yesApplied Sciences, 2021
Ahead geological prospecting, which can estimate adverse geology ahead of the tunnel face, is necessary in the process of tunnel construction. Due to its long detection range and good recognition effect on the interface, the seismic method is widely used

Inversion of Love waves in earthquake ground motion records for two-dimensional S-wave velocity model of deep sedimentary layers

open access: yesEarth, Planets and Space, 2021
We propose a new waveform inversion method to estimate the 2D S-wave velocity structure of deep sedimentary layers using broadband Love waves. As a preprocessing operation in our inversion scheme, we decompose earthquake observation records into velocity

Geology differentiation by applying unsupervised machine learning to multiple independent geophysical inversions [PDF]

open access: yesGeophysical Journal International, 2021
SUMMARYEffective quantitative methods for integrating multiple inverted physical property models are necessary to increase the value of information and advance interpretation further to produce interpretable geology models through geology differentiation.

New perspectives on Solid Earth Geology from Seismic Texture to Cooperative Inversion [PDF]

open access: yesScientific Reports, 2019
AbstractSeismic and electromagnetic methods are fundamental to Solid Earth research and subsurface exploration. Acquisition cost reduction is making dense 3D application of these methods accessible to a broad range of geo-scientists. However, the challenge of extracting geological meaning remains.

Geology-geophysics integrated inversion in Mount Isa South, Queensland

open access: yes, 2023
Taking advantage of all available information including geological and geophysical datasets is important to understand the subsurface. Integration of geological and geophysical datasets is commonly limited to the interpretation of areaspecific case studies and has seldom been addressed by automated techniques. Considering, the geometry of rock units as

Synthetic modelling of downhole resistivity data to improve interpretation of basin morphology from magnetotelluric inversion

open access: yesEarth, Planets and Space, 2020
Prospective Proterozoic units in the southern Mount Isa Province are concealed by a poorly defined extent of younger basin cover, leading to poor exploration success.
