Enhancing the value of public vintage seismic data in the Italian offshore

open access: yesGeoscience Data Journal, 2019
Vintage geophysical data represent a huge heritage for the whole scientific community (Sopher, 2018; Schaming et al., 2017; Diviacco et al., 2015) because, despite the antiquated acquisition methods and processing tools, they are generally characterized ...

Multilevel Assimilation of Inverted Seismic Data With Correction for Multilevel Modeling Error

open access: yesFrontiers in Applied Mathematics and Statistics, 2021
With large amounts of simultaneous data, like inverted seismic data in reservoir modeling, negative effects of Monte Carlo errors in straightforward ensemble-based data assimilation (DA) are enhanced, typically resulting in underestimation of parameter ...

Recognition and reconstruction of coherent energy with application to deep seismic reflection data [PDF]

open access: yes, 2000
Reflections in deep seismic reflection data tend to be visible on only a limited number of traces in a common midpoint gather. To prevent stack degeneration, any noncoherent reflection energy has to be removed.

Can learning from natural image denoising be used for seismic data interpolation? [PDF]

open access: yesGeophysics, 2019
We have developed an interpolation method based on the denoising convolutional neural network (CNN) for seismic data. It provides a simple and efficient way to break through the problem of the scarcity of geophysical training labels that are often ...

Imaging the plate boundary between Greenland and North America within the Kane Basin by means of geophysical data

open access: yesGeophysical Research Letters, 2016
The Nares Strait is a waterway separating NW Greenland and North America. The nature of the Nares Strait has been subject of discussion for decades, especially if it represents a transform fault that compensated the opening of the Baffin Bay in the ...

3-D Data Interpolation and Denoising by an Adaptive Weighting Rank-Reduction Method Using Multichannel Singular Spectrum Analysis Algorithm

open access: yesSensors, 2023
Addressing insufficient and irregular sampling is a difficult challenge in seismic processing and imaging. Recently, rank reduction methods have become popular in seismic processing algorithms for simultaneous denoising and interpolating.
