Análise da sensibilidade de parâmetros da simulação estocástica em reservatório...

Geostatistical simulation techniques have an important role in petroleum reservoir characterization. With this tool it is possible to reproduce observed heterogeneities and to characterize better the reservoir geology. However, as there are many variables to be analyzed and interpreted by geologists, it is necessary an uncertainty study of parameters used in the project. Thus, the main aim of this paper is to a...

Sedimentary dynamic and composition of a tidal channel in a tropical hot semi-a...

Tidal channels comprise a peculiar and dynamic environment. This paper aims to recognize the sedimentary distribution and composition of a tidal channel located in a semi-arid climate area in order to understand the sedimentary dynamics of the region.This region has economic and environmental importance considering that several activities are developed in the area such as; salt industry and aquaculture with shr...

A three-dimensional (3D) structural model for an oil-producing basin of the Bra...

Hydrocarbon discoveries in Equatorial Brazil, Equatorial Africa and French Guiana-Suriname-Guyana have recently confirmed their importance as new exploration frontiers. The Mundaú sub-basin, located on the Brazilian Equatorial Margin, comprises four producing fields in shallow waters: Xar´eu, Atum, Espada e Curim˜ a. In order to understand the structural and seismic-stratigraphic frameworks of an oil-producing ...

Morphology of submarine canyons along the continental margin of the Potiguar Ba...

New insights into equatorial slope morphology were acquired through analysis of the continental margin of the Potiguar Basin (NE Brazil). In this paper, we present the first full data coverage of the seafloor between the upper and middle continental slopes (100e1300 m) adjacent to the Brazilian equatorial margin, developed using multibeam bathymetric data. Some of the submarine canyons mapped in this study have...

Sequence stratigraphy and organic geochemistry: An integrated approach to under...

An organic geochemical investigation combined with sequence stratigraphy was performed in the Ceara´ Basin, an offshore basin located in Northeastern Brazil. The information available from 30 well logs (gamma-ray, resistivity, density), besides geochemical (TOC, and pyrolysis indexes) and isotopic (δ13C) data, aided the preparation of a dataset for this study. The application of sequence-stratigraphic methods h...

Pláceres marinhos entre Caucaia e Trairi, estado do Ceará, Nordeste do Brasil

This work studies the morphology , textural classification and heavy minerals in bottom sediments of the inner continental shelf of Ceará , between the cities of Caucaia (Fortaleza Metropolitan Region ) and Trairi. The digital model of bottom continental shelf exposed a smooth relief with the presence of irregularities between the cities Paracuru and São Gonçalo do Amarante, with a possible occurrence of paleoc...

Aspectos sedimentológicos do talude continental setentrional do Rio Grande do N...

Sedimentological aspects of northern continental slope of Rio Grande do Norte, NE of Brazil. The continental slopes of north and northeast regions of Brazil lack data and knowledge and they represent an ecosystem of economic and environmental importance. The aim of this study is to assess the sedimentology of the continental slope of Potiguar Basin, NE Brazil. The samples were collected with box-corer and were ...

Tectono-sedimentary evolution and petroleum systems of the Mundaú subbasin: a n...

The Brazilian equatorial margin (BEM) evolved in response to transform motion between Brazil and Africa. In 2012, Petrobras drilled the Pecem well in the Mundaú subbasin (Ceará Basin) of the BEM to record the first deep-water oil discovery in the region. This work investigates the deep-water evolution of the Mundaú subbasin focusing on its structural and sedimentary evolution, and characterizes the petroleum sy...

Mapeamento de estruturas submersas e sedimentologia utilizando dados SRTM Plus ...

Evolução tectono-sedimentar e sistema petrolífero de uma nova fronteira explora...

The Brazilian Equatorial Margin (BEM) evolved in response to transform motion between Brazil and Africa. The Mundaú sub-basin, Ceará basin, is an oil and gas producing region with four fields in shallow waters (Xaréu, Atum, Espada e Curimã). Besides that, in 2012, Petrobras drilled the Pecém well recording the first deep water oil discovery in the Mundaú sub-basin. This work aims at: Recognizing the 3D geometry...
