A new tectono sedimentary framework of the Jurassic succession in the Merjan oil field, Central Iraq

open access: yesJournal of Petroleum Exploration and Production Technology, 2019
In the Merjan oil field (Central Iraq), the previous 2D seismic interpretation of subsurface geometry had been revealed mound facies which was interpreted as large carbonate buildup within carbonate Najmah formation of Jurassic age. The exploration well (

Understanding the Effect of Different Prior Knowledge on CNN Fault Interpreter

open access: yesIEEE Access, 2023
As deep learning (DL) models have been successfully applied to various image processing tasks, DL models, particularly convolutional neural networks (CNN), have been introduced into the geosciences to assist geologists in faster seismic interpretation ...

Seismic attribute analysis for enhanced interpretation of the internal reflectivity within the Kevitsa Ni-Cu-PGE bearing intrusion, northern Finland [PDF]

open access: yesBulletin of the Geological Society of Finland
A three-dimensional seismic reflection survey was conducted in 2010 in northern Finland over the Kevitsa mafic-ultramafic intrusion that hosts a large, disseminated Ni–Cu–PGE sulfide deposit.

Cenozoic tectonic subsidence in the Upper Assam Basin, NE India

open access: yesGeosystems and Geoenvironment
The Upper Assam Basin is an intermontane foreland basin surrounded by gigantic mountain belts in NE India. The structural geometry of the basin is controlled by the tectonic interactions of the Himalayan orogenic belt in the north, Mishmi thrusts in the ...

Aspects of automated seismic interpretation

open access: yes, 2020
The interpretation of seismic data is an integrated process that requires geophysical knowledge and an intuitive geological understanding. While seismic interpretation is essential in order to accumulate knowledge and build an understanding of the ...

The different approaches in seismic stratigraphy interpretation [PDF]

open access: yesTehnika, 2018
This paper presents two basic approaches in seismic stratigraphy interpretation. The first one as starting point have seismic sections, whose interpretation in the later stage correlates with well data.

Regional Seismic Wavefield Propagation [PDF]

open access: yes, 2004
Through the examination of local and regional seismic waveform data the crust and upper mantle of southern California are investigated. Using local and regional seismic phases such as Pn, Sn, PL, and surface waves, seismic wave velocities of interesting

Redescription of the Triassic cynodont Cistecynodon parvus and reassessment of its phylogeny

open access: yesThe Anatomical Record, EarlyView.
Abstract Cynodontia is an important subclade of Therapsida that first occurred in the late Permian. It includes extinct subclades which are the non‐mammaliaform cynodonts and Mammaliaformes, with the latter ultimately giving rise to crown mammals. The systematics of non‐mammaliaform cynodonts has been extensively studied and is relatively well‐resolved,

Enhanced Discrimination of Seismic Geological Channels Based on Multi-Trace Variational Mode Decomposition

open access: yesApplied Sciences, 2022
The spectral decomposition is a valuable tool for improving the resolution of seismic interpretation, and thus can improve the accuracy of the subtle geo-features (thin and narrow channels, thin reservoirs, etc.).
