Integrating outcrop and subsurface data to improve the predictability of geobodies distribution using a 3D training image: A case study of a Triassic Channel – Crevasse-splay complex
(Elsevier, 2021-07)
Fluvial sandstones deposited by high-sinuosity fluvial systems are one of the most complex reservoirs to predict and model with confidence, a reflection of both the geometries and complex distribution of the component ...
Cross-strata palaeocurrent analysis using virtual outcrops
(2021-01-01)
Although virtual outcrops or digital outcrop model applications in geological studies are becoming increasingly common, virtually no attention has been given to acquisition of palaeocurrent data from cross-strata. Palaeocurrent ...
Imageamento digital de paleocavernas colapsadas com georadar
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Geodinâmica e GeofísicaGeodinâmica; Geofísica, 2012-04-27)
In this study, the methodological procedures involved in digital imaging of collapsed
paleocaves in tufa using GPR are presented. These carbonate deposits occur in the Quixeré
region, Ceará State (NE Brazil), on the western ...
Reservoir architecture and heterogeneity distribution in floodplain sandstones: Key features in outcrop, core and wireline logs
(Wiley Blackwell Publishing, Inc, 2020-06)
Exploration and production from formations deposited in low-gradient fluvial systems is typically associated with a high degree of uncertainty; a reflection of the inherent characteristics of these environments, notably ...
Uma Abordagem para Detecção Automática de Planos em Modelos Digitais de Afloramentos Baseada em PCA
(Universidade do Vale do Rio dos Sinos, 2014-09-19)
The use of LIDAR (Light Detection and Ranging) systems for gathering spatial data has been extensively used in geological studies. This type of digital remote sensing delivers high resolution and accuracy, resulting in 3D ...

Proposta metodológica para o imageamento, caracterização, parametrização e geração de modelos virtuais de afloramentos
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Geodinâmica e GeofísicaGeodinâmica; Geofísica, 2013-01-31)
The aim of this work was to describe the methodological procedures that were
mandatory to develop a 3D digital imaging of the external and internal geometry of the analogue
outcrops from reservoirs and to build a Virtual ...
Outcrop Explorer: um sistema de renderização baseada em pontos para visualização e interpretação de modelos digitais de afloramento
(Universidade do Vale do Rio dos Sinos, 2013-10-25)
The use of LIDAR-based models for geological outcrop studies has increased in the last decade, especially in the last five years. This technique has proven its potential to represent digitally tridimensional field data ...
