Waveform inversion of the S reflector west of Spain: fine structure of a detachment fault. [PDF]
, 2005 The S reflection west of Iberia has been interpreted as a low-angle detachment fault separating crustal fault blocks from partially serpentinized mantle. We apply full waveform inversion to investigate the fine structure of S.

High resolution pre-stack seismic inversion using few-shot learning
Artificial Intelligence in Geosciences, 2022 We propose to use a Few-Shot Learning (FSL) method for the pre-stack seismic inversion problem in obtaining a high resolution reservoir model from recorded seismic data.

Envelope-based constrained model for multiparameter pre-stack seismic inversion
Journal of Petroleum Exploration and Production Technology, 2022 Pre-stack seismic inversion is an effective method to estimate multiparameter from seismic reflection data in the oil–gas reservoir exploration. In order to get a reliable inverted parameter result, a constrained model is commonly used to reduce the ...

Applicability Analysis of Pre-Stack Inversion in Carbonate Karst Reservoir
Energies, 2022 Although pre-stack inversion has been carried out on reservoir prediction, few studies have focused on the application of pre-stack for seismic inversion in fractured-cavity carbonate reservoirs.

Surface-consistent amplitude corrections for single or multicomponent sources and receivers using reciprocity and waveform inversion [PDF]
, 2006 In land seismics, near-surface conditions often vary within surveys, resulting in differences in source strength and signature. Furthermore, discrepancies between closely spaced recordings are also commonly observed.

Multiple Scenario Inversion of Reflection Seismic Prestack Data [PDF]
Proceedings, 2012 Inversion of prestack seismic data is a highly non-unique inverse problem. Many elastic models exists that fit seismic data observations equally well within the data uncertainty. In a probabilistic formulation of the inverse problem, a full description of such variability is described by the a posteriori probability distribution.

Ray-based stochastic inversion of prestack seismic data for improved reservoir characterization [PDF]
, 2009 Trace inversion for reservoir parameters is affected by angle averaging of seismic data and wavelet distortion on the migration image. In an alternative approach to stochastic trace inversion, the data are inverted prestack before migration using 3D ...
