A directional coherence attribute for seismic interpretation [PDF]
SEG Technical Program Expanded Abstracts 2017, 2017 The coherence attribute is one of the most commonly used attributes in seismic interpretation. In this paper, we propose building on the recently introduced Generalized Tensor-based Coherence (GTC) attribute to make it directionally selective. This directional selectivity is achieved by selecting a directional Gaussian preprocessing kernel and applying

Evidence of Lithospheric Boudinage in the Grand Banks of Newfoundland from Geophysical Observations
Geosciences, 2021 The evolution of the passive margin off the coast of Eastern Canada has been characterized by a series of rifting episodes which caused widespread extension of the lithosphere and associated structural anomalies, some with the potential to be classified ...

GAN-supervised Seismic Data Reconstruction: An Enhanced-Learning for Improved Generalization [PDF]
arXiv, 2023 Seismic data interpolation of irregularly missing traces plays a crucial role in subsurface imaging, enabling accurate analysis and interpretation throughout the seismic processing workflow. Despite the widespread exploration of deep supervised learning methods for seismic data reconstruction, several challenges still remain open.

Gravity modelling along CROP04 seismic profile [PDF]
, 2007 The processing and interpretation of seismic lines, together with the analysis of surficial geological data and hydrocarbon wells data, are powerful tools for the investigation of crust structures. Nevertheless, for depths exceeding that portion of crust

Methane Hydrate Stability and Potential Resource in the Levant Basin, Southeastern Mediterranean Sea
Geosciences, 2019 To estimate the potential inventory of natural gas hydrates (NGH) in the Levant Basin, southeastern Mediterranean Sea, we correlated the gas hydrate stability zone (GHSZ), modeled with local thermodynamic parameters, with seismic indicators of gas.

CONSS: Contrastive Learning Method for Semisupervised Seismic Facies Classification
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023 Recently, convolutional neural networks (CNNs) have been widely applied in the seismic facies classification. However, even state-of-the-art CNN architectures often encounter classification confusion distinguishing seismic facies at their boundaries.

3D Curvature Analysis of Seismic Waveforms and its Interpretational Implications [PDF]
, 2019 The idea of curvature analysis has been widely used in subsurface structure interpretation from three-dimensional (3D) seismic data (e.g., fault/fracture detection and geomorphology delineation) by measuring the lateral changes in the geometry of seismic events.
