Uncertainty-Weighted Robust Frequency-Scanning AVO Inversion for Fluid Prediction in Marine Low-Permeability Gas-Bearing Sandstones: A Case Study from the Xihu Sag, East China Sea

Journal of Marine Science and Engineering
Marine low-permeability gas-bearing sandstones are commonly characterized by thin sand–mud interbeds, poor reservoir properties, limited seismic bandwidth, and heterogeneous pore structures and fluid distributions, which make stable fluid prediction from

Imaging Continental Rifting Structures From Eastern Gondwana Breakup by Full‐Waveform Inversion of Marine Wide‐Angle Seismic Data

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract The Lord Howe Rise (LHR), a submerged continental fragment of Zealandia offshore eastern Australia, provides a rare opportunity to investigate the fine‐scale structure of a magma‐poor rifted margin. This study applies full waveform inversion (FWI) of 2D marine wide‐angle seismic data acquired with densely deployed ocean‐bottom seismometers ...

Machine Learning‐Based Seismic Subsurface Characterization: The State of the Art and Future Perspectives

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 4, December 2025.
Abstract Seismic subsurface characterization involves interpreting seismic records to delineate geological features and estimate the physical properties of subsurface rocks (such as lithofacies, porosity, and fluid saturation). As an effective remote sensing technology to characterize the large‐scale spatial distribution of subsurface properties ...

Oligocene—Miocene Tectono‐Stratigraphic Development of the Southern Levant Basin, Eastern Mediterranean Sea

Basin Research, Volume 37, Issue 6, November/December 2025.
Synthesis of Late Burdigalian tectono‐stratigraphic events occurring in and around the southern Levant Basin. Highlighted are the active NW‐Se‐striking normal faults nucleating onshore Sinai and across the southern Levant Basin. The offshore strike‐slip fault networks are also highlighted and are believed to be related to the same event which nucleated

Hellenic Subduction System and Upper‐Plate Structures Revealed by Deep High‐Resolution Seismic‐Reflection Profiles and Seafloor Bathymetry

Tectonics, Volume 44, Issue 9, September 2025.
Abstract The Hellenic forearc is one of the least understood forearc systems globally due to limited availability of high‐resolution imagery of its deep structure, especially landward of the Mediterranean Ridge. Here, we combine widely spaced high‐resolution multichannel seismic‐reflection profiles with seafloor morpho‐bathymetric analysis and ...

Image‐Domain Least‐Squares Migration Through Preconditioned Hessian

Geophysical Prospecting, Volume 73, Issue 7, September 2025.
ABSTRACT Image‐domain least‐squares migration (IDLSM), which typically employs a diagonally dominant Hessian with narrow bandwidth for the inverse problem, provides an efficient deconvolution strategy for subsurface reflectivity imaging. Conventional methods often rely on the adjoint of the Born/Kirchhoff modelling operator to compute the Hessian ...

Enhanced density estimation from prestack inversion of multicomponent seismic data

, 2010
Using 3C-2D seismic data in the Albacora block, Campos Basin, Brazil, we analyzed the potential of multicomponent data for density esti-mation by simultaneously inverting prestack compressional and mode-converted seismic data.
