Encoding the Subsurface in 3D with Seismic [PDF]

open access: yesarXiv
This article presents a self-supervised generative AI approach to seismic data processing and interpretation using a Masked AutoEncoder (MAE) with a Vision Transformer (ViT) backbone. We modified the MAE-ViT architecture to process 3D seismic mini-cubes to analyze post-stack seismic data.

A fiber‐based deterioration modeling framework for reinforced concrete structures subject to spatially non‐uniform corrosion patterns described by limited information

open access: yesStructural Concrete, EarlyView.
Abstract Reinforced concrete structures are often subject to significantly non‐uniform corrosion patterns. In real situations, the information available about deterioration is incomplete and sometimes is reduced to qualitative judgments formulated by inspectors based on in‐situ surveys.

Radiometric Constraints on the Timing, Tempo, and Effects of Large Igneous Province Emplacement

open access: yesGeophysical Monograph Series, Page 27-82., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Delineating Plio-Pleistocene channels (gas reservoirs) via seismic attributes in Baltim Gas Field, Nile Delta, Egypt

open access: yesMongolian Geoscientist
The Baltim gas fields in the offshore Nile Delta contain substantial gas condensate accumulations. This study aims to identify Pleistocene (El-Wastani formation) and Pliocene (Kafr El-Sheikh formation) reservoirs.

Experimental behavior of shear deficient RC beams strengthened with CFRP strips against reversible cyclic earthquake load

open access: yesStructural Concrete, EarlyView.
Abstract This study aims to prevent sudden and brittle shear failures in reinforced concrete beams, which are frequently caused by deficiencies in shear reinforcement. Following the Kahramanmaraş earthquakes in Turkey on February 6, 2023, inspections revealed that many reinforced concrete beams suffered severe damage due to design errors, high shear ...

Acoustic Impedance Prediction Using an Attention-Based Dual-Branch Double-Inversion Network [PDF]

open access: yesarXiv
Seismic impedance inversion is a widely used technique for reservoir characterization. Accurate, high-resolution seismic impedance data form the foundation for subsequent reservoir interpretation. Deep learning methods have demonstrated significant potential in seismic impedance inversion.

Blind Curvelet based Denoising of Seismic Surveys in Coherent and Incoherent Noise Environments

open access: yes, 2018
The localized nature of curvelet functions, together with their frequency and dip characteristics, makes the curvelet transform an excellent choice for processing seismic data.

A seven‐year investigation on the flexural performance of cement‐based multi‐layered roof elements exposed to outdoor conditions

open access: yesStructural Concrete, EarlyView.
Abstract As part of a regional research project started in 2011, the Politecnico di Milano coordinated a research consortium aimed at developing a cement‐based multi‐layered roof element designed to achieve structural safety, lightness, thermal efficiency, and compatibility with photovoltaic systems.

Geological Interpretation of Reflection Seismic Data

open access: yes, 2012
This research consists of all these aspects in a brief. Starting from the introduction to the seismic methods in Chapter (1). In Chapter (2) We tried to give a brief introduction about the basics of the different types of waves, and fundamental of seismic data and it’s definition like multiples, processing, etc.
