AVO Didactic Analysis from Simplified Modeling of Seismic Data in Libra Oil Field of the Pre-Salt Region, Brazil

Kaio da Silva Pimentel Figueiredo, Kaendra Williams Temoteo, Rafael Ximenes Goncalves, Yasmim Monteiro Cordeiro, Rogério Manhaes Soares, Hans Schmidt Santos, Claudiomar Rodrigues Franco, Felipe Barbosa Venancio de Freitas, Christyne Barros de Sá
In this study, a certain zone of Libra oil field of the pre-salt region was se-lected to be analyzed for didactic purposes in order to simulate AVO re-sponses. The region was modeled using seismic data, setting up a typical oil system with source rock (shale), reservoir rock (sandstone), and seal rock (salt). Thus, a set of parameters such as seismic wave velocity, density and Poisson’s ratio for the studied zone w

Geomagnetic Mapping of the Macaé Region, Brazil

Igor Rodrigues Salvador de Menezes, Júllia Medeiros Figueiredo, Davi Antonio Ferreira Velloso, Maria Eduarda da Silva Bento, Iuri de Azevedo Lima, Hans Schmidt Santos
This work presents the geomagnetic characterization of the municipality of Macaé, Brazil. Data from IGRF12 (twelfth edition of International Geomag-netic Reference Field) were used. Through the data collected in a regular grid of 0.1 degrees of the components, north, east and vertical were generated maps of components, inclination, declination, horizontal component and geomagnetic total field. The results showed important relative

Magnetometric Characterization of the Rio do Peixe Basin, Brazil

Kaio da Silva Pimentel Figueiredo, Gabriel Machado Stutz Xavier, Dayane de Souza Pereira, Jennifer Santos Rosa, Tainá de Mello Ribeiro, Hans Schmidt Santos, Felipe Barbosa Venancio de Freitas, Rogério Manhaes Soares, Rayssa Barcellos Paiva
This work presents the analysis of magnetometric data of an aerial survey conducted in the Rio do Peixe Sedimentary Basin, which is a promising oil producing region in the state of Paraíba, Brazil. The collected aeromagne-tometric data allowed the preparation of maps regarding magnetic anomaly, horizontal and vertical derivatives, analytical signal and Euler Decon-volution that were compared w

The Island of Tubuai (French Polynesia) Landfall of Cyclone Oli on the 5th of February 2010

Jean-Pierre Barriot, Jonathan Serafini, Keitapu Maamaatuaiahutapu, Lydie Sichoix
The Island of Tubuai (Australs Archipelago, South Pacific) was directly hit by the tropical cyclone (TC) Oli on February 5th, 2010. For the first time on an island in French Polynesia, we have been able to monitor the progress and the impact of TC Oli as revealed by the meteorological, GPS and sea level pressure data. TC Oli is one of the most intense c

Modeling the Specific Seismic Risk Considering the Weight of Determining Variables

Liber Galbán Rodriguez, Elio Quiala Ortiz
The seismic risk determination for any country is a vital tool in the process of physical planning, construction and reduction of disasters caused by earthquakes. In recent years, there have been several studies on the subject, however, different methodologies could be improved from the design of a set of basic criteria, which using the advantages of Geographic Information Systems (GIS), could help to establish greater clarity in the seismic risk determining. To meet this goal, in this study, th...
