Facies classification from well logs using an inception convolutional network [PDF]

open access: yesarXiv, 2017
The idea to use automated algorithms to determine geological facies from well logs is not new (see e.g Busch et al. (1987); Rabaute (1998)) but the recent and dramatic increase in research in the field of machine learning makes it a good time to revisit the topic. Following an exercise proposed by Dubois et al. (2007) and Hall (2016) we employ a modern

Alluvial to lacustrine sedimentation in an endorheic basin during the Mio-Pliocene: The Toro Negro Formation, Central Andes of Argentina [PDF]

open access: yes, 2018
A 2400 m-thick sedimentary column belonging to the Toro Negro Formation was recorded along the Quebrada del Yeso, Sierra de Los Colorados (Vinchina Basin), La Rioja province, NW Argentina. The Vinchina basin is a good example of a closed basin surrounded

Facies Classification with Copula Entropy [PDF]

open access: yesarXiv
In this paper we propose to apply copula entropy (CE) to facies classification. In our method, the correlations between geological variables and facies classes are measured with CE and then the variables associated with large negative CEs are selected for classification.

Generating Geological Facies Models with Fidelity to Diversity and Statistics of Training Images using Improved Generative Adversarial Networks [PDF]

open access: yesarXiv, 2019
This paper presents a methodology and workflow that overcome the limitations of the conventional Generative Adversarial Networks (GANs) for geological facies modeling. It attempts to improve the training stability and guarantee the diversity of the generated geology through interpretable latent vectors.

Investigating the role of basement structures in controlling facies characteristics, depositional models, and diagenetic alterations of the Sarvak Formation in the eastern and western regions of the Persian Gulf [PDF]

open access: yesJournal of Stratigraphy and Sedimentology Researches
The Sarvak Formation, as one of Iran's most important hydrocarbon reservoirs, has been deposited and evolved under active tectonic conditions in various regions of the Zagros, including the Persian Gulf.
