Recent Developments Combining Ensemble Smoother and Deep Generative Networks for Facies History Matching [PDF]

open access: yes, 2020
Ensemble smoothers are among the most successful and efficient techniques currently available for history matching. However, because these methods rely on Gaussian assumptions, their performance is severely degraded when the prior geology is described in

The Facies and Metamorphism Types Determination of Metamorphic Rock in The Part of Mekongga Complex

open access: yesGeosfera Indonesia, 2020
Lambolemo Village is geomorphologically dominated by hilly slopes morphology. Lithology in the form of metamorphic rocks are mica schists and chlorite schists. The present research aimed to determine the facies and metamorphism types of metamorphic rocks

Pyroclastic Density Current Facies in the Millennium Eruption of Tianchi Volcano, Northeast China: Insights From Topography, Stratigraphy, Granulometry, and Petrography

open access: yesFrontiers in Earth Science, 2020
Large-scale pyroclastic density currents (PDCs) produce inhomogeneity of distributions, thicknesses, stratigraphic structures, and temperatures, thereby causing poor understanding of PDC emplacement processes.

Speleothems and Biomineralization Processes in Hot Spring Environment: The Case of Aedipsos (Edipsos), Euboea (Evia) Island, Greece

open access: yesJournal of Marine Science and Engineering, 2022
Caves with hot springs and speleothem deposits are infrequent environments of high scientific interest due to their unique environmental conditions. The selected site is a small open cave with a hot spring and stalactites in the Aedipsos area (NW Euboea ...

Latent Diffusion Model for Conditional Reservoir Facies Generation [PDF]

open access: yes, 2023
Creating accurate and geologically realistic reservoir facies based on limited measurements is crucial for field development and reservoir management, especially in the oil and gas sector. Traditional two-point geostatistics, while foundational, often struggle to capture complex geological patterns.

Cyanobacterial Diversity in Microbial Mats from the Hypersaline Lagoon System of Araruama, Brazil: An In-depth Polyphasic Study

open access: yesFrontiers in Microbiology, 2017
Microbial mats are complex, micro-scale ecosystems that can be found in a wide range of environments. In the top layer of photosynthetic mats from hypersaline environments, a large diversity of cyanobacteria typically predominates.

Use of Anemometric Results and Threshold Velocities for Determination of Proper Regions Where Sand Storms are Generated (Case Study: Around the Synoptic Station of Yazd) [PDF]

open access: yesDesert, 2012
In order to recognize the wind erosion situation of a region, the survey of its windiness is not sufficient and the physical characteristics of earth are of importance too.

Origin and significance of 'dispersed facies' basal ice: Svínafellsjökull, Iceland [PDF]

open access: yes, 2010
Dispersed facies basal ice - massive (i.e. structureless) ice with dispersed debris aggregates - is present at the margins of many glaciers and, as a product of internal glacial processes, has the potential to provide important information about the ...

Palaeoecology of corals and stromatoporoids in a late Silurian biostrome in Estonia [PDF]

open access: yes, 2014
A middle Ludlow biostrome at Katri, western Estonia, the richest accumulation of corals and stromatoporoids in Estonia, is partly exposed in a coastal section ca. 1 m high, 150 m long. The fully marine biostrome consists of 5 layers of skeletal carbonate,

Natural history of liver disease in a large international cohort of children with Alagille syndrome: Results from the GALA study

open access: yesHepatology, EarlyView., 2022
Natural history of liver disease in a large international cohort of children with Alagille syndrome: Results from the GALA study. Abstract Background and Aims Alagille syndrome (ALGS) is a multisystem disorder, characterized by cholestasis. Existing outcome data are largely derived from tertiary centers, and real‐world data are lacking.
