Machine Learning-Based Probabilistic Lithofacies Prediction from Conventional Well Logs: A Case from the Umiat Oil Field of Alaska

open access: yesEnergies, 2020
A good understanding of different rock types and their distribution is critical to locate oil and gas accumulations in the subsurface. Traditionally, rock core samples are used to directly determine the exact rock facies and what geological environments ...

A Quantitative Interpretation of Seismicity and Seismic Activity [PDF]

open access: yesGeophysical Journal International, 1967
Summary A new method for computation of seismicity has been worked out and the concept seismic activity has been mathematically formulated as an enlargement of seismicity. For computation of seismic activity a mathematical representation of the energy density function of an earthquake is needed.

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 ...

Fault interpretation in seismic reflection data: an experiment analysing the impact of conceptual model anchoring and vertical exaggeration [PDF]

open access: yesSolid Earth, 2019
The use of conceptual models is essential in the interpretation of reflection seismic data. It allows interpreters to make geological sense of seismic data, which carries inherent uncertainty.

Seeing through the CO2 plume: joint inversion-segmentation of the Sleipner 4D Seismic Dataset [PDF]

open access: yesVolume 42 Issue 7 Jul 2023 Pages 446 516, 2023
4D seismic inversion is the leading method to quantitatively monitor fluid flow dynamics in the subsurface, with applications ranging from enhanced oil recovery to subsurface CO2 storage. The process of inverting seismic data for reservoir properties is, however, a notoriously ill-posed inverse problem due to the band-limited and noisy nature of ...

The role of visual saliency in the automation of seismic interpretation [PDF]

open access: yesarXiv.org, 2018
In this paper, we propose a workflow based on SalSi for the detection and delineation of geological structures such as salt domes. SalSi is a seismic attribute designed based on the modelling of human visual system that detects the salient features and ...

Analyzing the seismic attributes, structural and petrophysical analyses of the Lower Goru Formation: A case study from Middle Indus Basin Pakistan

open access: yesFrontiers in Earth Science, 2023
The purpose of this research is to delineate the structures of the Lower Goru Formation, investigate fluid properties, and clarify the hydrocarbon-prone areas through seismic attributes analysis. First, the acquired data was matched by the interpretation

Machine learning elucidates the anatomy of buried carbonate reef from seismic reflection data

open access: yesArtificial Intelligence in Geosciences, 2023
A carbonate build-up or reef is a thick carbonate deposit consisting of mainly skeletal remains of organisms that can be large enough to develop a favourable topography.
