1. Iso-velocity maps. A vibration control tool in quarries
Urban growth around mining areas has brought problems such as neighborhood's discomfort due to blasting vibrations, which can cause structural damage to the houses, dust and atmospheric overpressure. In Brazil, environmental restrictions are increasingly rigorous and seismic monitoring is required as an environmental control measure. This study aims to analy

2. Seismic interpretation of self-organizing maps using 2D color displays
Classificação não supervisionada de padrões em grupos é formalmente chamada de agrupamento. Dependendo da área de aplicação estes padrões são chamados de listas, observações ou vetores. Na exploração geofísica, padrões são associados a atributos sísmicos, formas de onda sísmicas ou fácies sísmicas.O principal objetivo deste artigo é mos

3. Arquitetura estratigráfica e arcabouço estrutural dos depósitos fluviais albianos da base da Formação São Mateus no Norte da Bacia do Espírito Santo
The main aim of this dissertation is make at the high-resolution stratigraphic subdivision of the basal section from the São Mateus Formation, Albian the Espírito Santo Basin. The interval studied is consists predominantly of alluvial deposits. Against the difficulties presented for the stratigraphic correlation of these deposits, as discussed by Wright &M

4. Obtenção de dados de saturação e pressão a partir de atributos derivados da sísmica 4D / Obtaining saturation and pressure maps from time-lapse seismic derived atributes
A utilização de dados de produção para o aumento da confiabilidade das previsões de produção de um campo apresenta limitações, principalmente no início do seu desenvolvimento, quando há menos dados observados e as incertezas sãomaiores. Uma alternativa para a melhora da qualidade do modelo é a utilização de mapas de saturação e pressão obti

5. Seimic resolution and time-to-depth conversion by the common-reflection-surface (CRS) method / Resolução sismica e conversão tempo-profundidade, atraves do metodo de superficie comum de reflexão (CRS)
The demand for large multiplicities in seismic processing has always been a tough target for the professionals involved in this area. Until recently, the major effort to meet this demand has been done during seismic acquisition, which, due to high cost, is not usually implemented. Recently, the Common Reflection Surface (CRS) technique filled this gap provid

6. Sismoestratigrafia do cretÃceo superior/ neÃgeno nas bacias de Pernambuco e da ParaÃba, NE do Brasil
This work presents the mapping of seismic sequences from the albian portion of the offshore basins of Pernambuco and Paraiba embasado in individualizaÃÃes of fÃcies and interpretation of seismic maps of isÃcronas. In Basin of Pernambuco were mapped four disagreements and four sequences (A, B, C, D), the basin of Paraiba has three disagreements, a surface

7. High resolution stratigraphy framework for carbonatic deposits of terciary of the Basin Campos / Geração de um arcabouço estratigráfico de alta resolução para depósitos carbonáticos terciários da Bacia de Campos
The Siri Member is of great importance due to the heavy oil content that is present on the carbonate platform developed during the Tertiary. Considering this importance, we conducted a study with the objective of generating a high resolution stratigraphic framework, on 3rd order sequences, using the interpretation of two seismic sections and the analysis of

8. History matching using statistical design, production data and saturation map / Ajuste de historico utilizando planejamento estatistico e combinação de dados de produção, pressão e mapas de saturação
The main objective of history matching is to improve numerical models of oil fields by incorporating observed data, production and pressure, into the characterization process, in order to obtain more reliable production forecasting. This technique presents some limitations mainly in the beginning of the development of oil fields, when less information is ava

9. AGRUPAMENTO E VISUALIZAÇÃO DE DADOS SÍSMICOS ATRAVÉS DE QUANTIZAÇÃO VETORIAL / CLUSTERING AND VISUALIZATION OF SEISMIC DATA USING VECTOR QUANTIZATION
This thesis suggests the use of a new method of seismic data clustering that can aid in the visualization of seismic maps. Seismic data are primarily made of signal and noise and, due to its dual composition, have asymmetric distributions. Seismic data are traditionally classified by methods that lead the proposed groups` references to their mean values. The

10. SEISMIC PATTERN RECOGNITION USING TIME-FREQUENCY ANALYSES / RECONHECIMENTO DE PADRÕES SÍSMICOS UTILIZANDO ANÁLISES TEMPO-FREQÜÊNCIA
Independent of the adopted methodology to perform the seismic facies analysis, the geological oriented spatial and temporal segmentation of the reservoir region should be carefully done. Depending on the complexity of the reservoir system, seismic data quality, and the experience of the interpreter, the level of confidence in an interpretation can vary from

11. Gravity crustal model for an andean section at 32° s considering upper mantle lateral density variation
Up to date, three gravity models for the Andean section at 32° south latitude have been published. Two of them did not have seismic reflection/refraction data to constrain the subsurface geometry. The other one included seismic data to fit thicknesses and determined density contrasts using velocity-density curves. Furthermore, all previous models assumed a

12. Incertezas associadas a caracterização de reservatorio utilizando dados sismicos e de poços com uma abordagem geoestatistica
A petroleum reservo ir was characterized through integration of geologic information obtained from the well and 3D seismic data. The integration was accomplished by using geoestatistical tools (kriging with extemal drift, collocated cokriging and stochastic simulation). The reservoir is composed by an altemance of turbiditic sandstone and non-reservoir facie
