Energy Science &Engineering, EarlyView.A support vector machine (SVM) algorithm was applied to quantitatively predict the connectivity of the sand bodies. Verification using dynamic and static data demonstrated that the prediction accuracy of the algorithm reached 88%. The quantitative sand body connectivity results were used to establish a single sand body model.

Известия Томского политехнического университета: Инжиниринг георесурсов, 2019 Due to hydraulic mining improvement there is a possibility to development prospects of Bakchar ore occurrence. There are various types of ores identified within the ore occurrence and hydraulic mining can be applied to extract loose ore only.

EUNOMÍA. Revista en Cultura de la Legalidad, 2022 El objetivo de este trabajo es identificar y caracterizar brevemente las maneras en que los juristas entienden el carácter prima facie de una norma. Para ello reconstruiré los dos sentidos que la literatura especializada usualmente le atribute: i) como una forma de presentar un problema de falta de información sobre el alcance de la norma (prima facie ...

Fossil biomass preserved as graphitic carbon in a late paleoproterozoic banded iron formation metamorphosed at more than 550°C [PDF]
, 2019 Metamorphism is thought to destroy microfossils, partly through devolatilization and graphitization of biogenic organic matter. However, the extent to which there is a loss of molecular, elemental and isotope signatures from biomass during high ...

Geological Journal, EarlyView.Charnockites with 2691–2607 Ma magmatic ages from the NMZ show arc‐magmatic geochemical signatures. They correspond to the lower‐crustal equivalent of the Chilimanzi Suite Granite in the Zimbabwe Craton. Lu‐Hf isotopic data of magmatic zircons show negative εHf(t) values (−11.18 to −2.20) with TDMC ages of 3699–3158 Ma, suggesting their protolith ...

Corals not serpulids: mineralized colonial fossils in the Lower Jurassic marginal facies of South Wales [PDF]
, 2002 Poorly preserved colonial corals occur near the base of the Lower Jurassic marginal facies at Southerndown, South Wales. Previously they have been interpreted as serpulid colonies, despite a dissimilarity to any serpulids known from elsewhere in the Lias

Application of Machine Learning in Rock Facies Classification with Physics-Motivated Feature Augmentation [PDF]
arXiv, 2018 With recent progress in algorithms and the availability of massive amounts of computation power, application of machine learning techniques is becoming a hot topic in the oil and gas industry. One of the most promising aspects to apply machine learning to the upstream field is the rock facies classification in reservoir characterization, which is ...

Accelerating Multi-attribute Unsupervised Seismic Facies Analysis With RAPIDS [PDF]
arXiv, 2020 Classification of seismic facies is done by clustering seismic data samples based on their attributes. Year after year, 3D datasets used by exploration geophysics increase in size, complexity, and number of attributes, requiring a continuous rise in the classification performance.

A Middle and Late Devensian sequence from the northern part of Kents Cavern (Devon, UK)
Journal of Quaternary Science, EarlyView.Abstract 1920s/30s excavation of a Middle Devensian sequence in the northern part of Kents Cavern recovered important Late Middle and Early Upper Palaeolithic archaeological material, including Britain's oldest known Homo sapiens remains. Questions remain about this material, including how it came to be in the cave.
