Vertical Seismic Profiling and Piggyback Experiment for Seismic Characterization of Geothermal Reservoirs: Case Study From Southern Tuscany, Italy

Geophysical Prospecting, Volume 74, Issue 6, July 2026.
ABSTRACT We present an approach for seismic characterization of a deep supercritical geothermal reservoir in the direct vicinity of an exploration well. Our investigation area is the Larderello geothermal field in Tuscany (Italy) where we focus on the K‐horizon, which is represented by a strong reflector at a depth of 3–6 km marking the geothermal ...

Viscoacoustic Full Wavefield Migration With Tomographic Q Estimation

Geophysical Prospecting, Volume 74, Issue 4, May 2026.
ABSTRACT Seismic wave propagation in the Earth's subsurface is influenced by anelastic attenuation, which causes energy loss and waveform distortion, degrading image resolution. This effect, quantified by the quality factor (Qf${{\textit {Q}}_f}$), is particularly pronounced in settings such as carbon capture and storage and near‐surface studies, where

Application of facies-controlled prestack geostatistical inversion method in high quality reservoir prediction of low permeability reservoir: A case study of V Oil Formation of Es₃³ in Block A

Youqicang pingjia yu kaifa, 2022
In order to solve the difficulties in prediction of high-quality reservoirs in low-permeability V Oil Formation of Es3 sub member in Block A, the residual velocity analysis, flattening and denoising of prestack gather data are carried out to improve the ...

Traveltime Tomography to Unravel the Chalk Group Structures at the Gassum CCS Site, Denmark

Geophysical Prospecting, Volume 74, Issue 3, March 2026.
ABSTRACT In carbon capture and storage (CCS) projects, it is important to investigate the seal properties, which often include the shallower part of the investigated area. Reflection seismic data in most of the Danish Basin appear less strong and coherent in the top 500 m, and hence reflectivity alone cannot be used to study the integrity of these ...

Seismic Rock Physics Inversion With Varying Pore Structure Parameters and Consolidation Parameter in Tight Sandstone Reservoirs

Geofluids, Volume 2026, Issue 1, 2026.
Tight sandstone gas holds significant exploration and development potential. However, its complex pore structure and heterogeneous consolidation make quantitative reservoir prediction challenging. In this study, we propose a novel seismic inversion method that incorporates consolidation parameter and pore structure parameters as constraints for ...

Seismic ray impedance inversion [PDF]

, 2010
This thesis investigates a prestack seismic inversion scheme implemented in the ray parameter domain. Conventionally, most prestack seismic inversion methods are performed in the incidence angle domain.

OBN seismic data PP- and PS-waves joint inversion and reservoir characterization

Frontiers in Earth Science
The use of seismic exploration data to invert shear (S-) wave information plays a very important role in oil and gas exploration, especially in reservoir prediction with increasingly complex lithology and deeper target layers. Combining longitudinal (P-)

A Possible Tsunamigenic Near‐Trench Strike‐Slip Fault, Offshore North Ecuador–South Colombia

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract Seismic reflection and bathymetry collected along the Ecuador–Colombia obliquely convergent margin allow the first characterization of the NNE‐trending, near‐trench strike‐slip Ancon Fault in the possible source region of the 1906‐Mw8.6–8.8 and 1979‐Mw8.2 earthquakes, which produced devastating tsunamis.
