1. Constraints from magnetotellurics on the geological structure across a seismic area associated with water wells in the Paraná basin, Brazil
ABSTRACT: The occurrence of earthquakes associated with the opening of groundwater wells is a very rare phenomenon. We present the results from a magnetotelluric profile of about 4 km-long that crosses a seismic zone near the town of Bebedouro, in the Northeastern part of the intra-cratonic Paraná basin, in Brazil. The seismic activity is thought to be caus

2. Experimental and numerical modeling of horizontally-bent buried pipelines crossing fault slip
Abstract The behavior and response of pipelines subjected to slip fault movement is studied by numerical simulations as well as experimental setup. A finite element modeling is also developed via ABAQUS software. In this study, an artificial accelerogram is applied to the system and matched against the response spectrum according to the standard No. 2800 (Ir

3. Métodos geoestatísticos de co-estimativas: aplicação aos dados do Campo Escola de Namorado / Co-estimation geostatistical methods: applications to the Namorado Oil Field data
Data used for studying petroleum reservoirs are obtained through drill core, well logs, seismic records and, as a consequence, they present different sampling scales. Multivariate geostatistics is a manner of integrating these data in order to co-estimate a poorly sampled variable based not only on its own information but also on a densely sampled variable.

4. Analysis of the steel braced frames equipped with ADAS devices under the far field records
The usefulness of supplementary energy dissipation devices is now quite well-known in earthquake structural engineering for reducing the earthquake-induced response of structural systems. The seismic behavior of structures with supplemental ADAS devices is concerned in this study. In this paper, the ratio of the hysteretic energy to input energy is compared

5. On the effect of the near field records on the steel braced frames equipped with energy dissipating devices
The behavior of braced steel frame structures is of special importance due to its extensive use. Also the application of active and semi-active control systems, regarding to their benefits in obtaining better seismic performance has increased significantly. The majority of the works on steel structures and steel connections has been done under far field reco

6. Estudo do potencial da técnica de nanossísmica para o monitoramento de hidrofraturamento em reservatórios de hidrocarbonetos
Hydraulic fracturing is an operation in which pressurised fluid is injected in the geological formation surrounding the producing well to create new permeable paths for hydrocarbons. The injection of such fluids in the reservoir induces seismic events. The measurement of this reservoir stimulation can be made by location these induced microseismic events. Ho

7. 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

8. Incorporação quantitativa de dados de sismica 4D no processo de ajuste de historico / Quantitative incorporation of seismic 4D in history matching process
Good decision making related to oilfield management depends on reliability of production forecast which demands calibrated reservoir simulation models. Due to the complexity of the production history matching process, there are many models with reasonable match but, many times, with different forecasts, mainly due to important heterogeneities that are not ob

9. Análise da trajetória de poços horizontais em reservatório de óleo pesado
A aplicação de métodos térmicos, para aumentar a recuperação de óleo pesado em campos maduros através da drenagem com poços horizontais e multilaterais, tem sido exaustivamente estudada, teórica e experimentalmente, testando novas ferramentas e novos métodos. A injeção contínua de vapor, através de um poço injetor e de um poço horizontal pro

10. Metodologia para ajuste de historico de produção em campos de petroleo utilizando dados de saturação de perfis / Methodology for production history matching of petroleum fields utilizing logging saturation data
In the production history matching process, the reservoir simulation model is modified in a way that it becomes consistent with production data, keeping the observed restrictions of the geological characterization phase. This technique is limited, mainly in mature fields, when the production history is not reliable, or in the beginning of production, when th

11. Aquisição, processamento e análise de dados de sísmica de alta resolução na plataforma continental norte do Rio Grande do Norte: Vale inciso do rio açu
Sobre a Plataforma Continental a norte do Estado do Rio Grande do Norte (NE do Brasil) está localizado um paleovale submerso durante o último glacial, que marca a continuação do rio mais importante desta área: o Rio Açu. Apesar do elevado nível de atividades de exploração da indústria petrolífera nessa região, existe pouca informação sobre sua

12. 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
