13. Estudo integrado de análogo a reservatórios petrolíferos fluviais: caracterização, parametrização e modelagem tridimensional de depósitos recentes do Rio Assu (Rio Grande do Norte/Brasil)
This work shows a integrated study of modern analog to fluvial reservoirs of Açu Formation (Unit 3). The modern analog studied has been Assu River located in the same named city, Rio Grande do Norte State, Northeast of Brazil. It has been developed a new methodology to parameterizating the fluvial geological bodies by GPR profile (by central frequency anten

14. 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

15. DETERMINING THE START OF PRECIPITATION ASPHALTENES IN BRAZILIAN CRUDE OIL AND THE IMPLICATIONS OF THE STABILITY IN CRUDE OILS MIXTURES / DETERMINAÇÃO DO INÍCIO DE PRECIPITAÇÃO DOS ASFALTENOS EM PETRÓLEOS BRASILEIROS E IMPLICAÇÕES NA ESTABILIDADE DE MISTURAS DE PETRÓLEOS
The crude oil can be understood as a mixture sufficiently polydisperse where its diverse components form a dispersion and/or solution whose original state can be modified in function of variations of temperature, pressure and composition causing, for example, the formation of organic deposits. The asphaltene constitutes heavy fractions of oils with great cap

16. Sedimentação mista carbonato-siliciclástico durante o albo-aptiano na porção emersa da bacia Sergipe-Alagoas
The Albian-Aptian mixed sediments, composed of carbonate and siliciclastic constituents, occur in the onshore portion of the Sergipe-Alagoas Basin, next to its current border. Outcrops are located 50 km to northwest from Aracaju and, for the greater part, in oil well areas. The interpretations now presented are based on outcrop description, georadar sections

17. AplicaÃÃo de um modelo paramÃtrico para a estimativa do transporte de sedimentos arenosos na Bacia de Campos / Application of a parametric model to assess the sandy sediment transport in the Campos Basin
Studies about sediment transport processes that occur in the Campos Basin are of great importance, since they can contribute for example to improve the comprehension of how the sedimentary deposits, that are potential oil reservoirs, take form or to provide elements that can help to understand the changes in marine bed forms on areas where submarine pipeline

18. Foliar anatomy of species of Chamaecrista Moench. (Leguminosae/Caesalpinioideae) occurring in rupestrial fields / Anatomia foliar de espécies de Chamaecrista Moench. (Leguminosae/Caesalpinioideae) ocorrentes em campo rupestre
Minas Gerais state flora presents different biomas but little is known about the diversity of its species, some of which secrete natural compounds having well-known biological activity. There is a large number of species of recognized economic interest in the Leguminosae family and in the rupestrial fields of Minas Gerais, totaling 28 of the 351 species incl

19. Mapeamento digital de análogos a reservatórios petrolíferos: exemplos para depósitos fluviais da Unidade Açu-3 - Bacia Potiguar
In the current work are presented the results about the study of digital mapping of analogs referents the fluvial oil reservoirs in the Açu Formation. With the regional recognizing in the south corner of Potiguar Basin was selected a area of 150 Km square in the west of Assu city. In this area was chosen the outcrops for the digital mapping and from the dat

20. Modeling and simulation of hydrodemetallation and hydrodesulfurization processes with transient catalytic efficiency
A model is presented for the description of the concentration behavior of organometallic and sulfurated compounds in hydrodemetallation and hydrodesulfurization catalytic processes, where catalyst effectiveness decreases with time. Due to the complexity of the mixture, an approach based on pseudocomponents was adopted. The system is modeled as an isothermal

21. Modelagem geologica orientada a objetos e simulação estocastica da geometria de reservatorios fluviais
In this work. an object based method for geological modeling named Stochastic Modeling ar Geometric Objects is proposed. to simulate the geometry and the architecture of fluvial reservoirs in a case study. Fluvial reservoirs are formed by channel fill deposits. which are the basic unit of the reservoir. The object channel is represented in cross-section by t

22. Geographical Coincidence of High Heat Flow, High Seismicity, and Upwelling, with Hydrocarbon Deposits, Phosphorites, Evaporites, and Uranium Ores
Oil deposits occur in deep sediments, and appear to be organic matter that has been transformed through the action of geothermal heat and pressure. Deep sediments, rich in biological remains, are created by ocean upwelling, caused in part by high geothermal heat flow through the sea bottom. Such regions correlate with enhanced seismic activity. We look for c

23. Improved Method for Determination of Respiring Individual Microorganisms in Natural Waters
A method is reported that combines the microscopic determinations of specific, individual, respiring microorganisms by the detection of electron transport system activity and the total number of organisms of an estuarine population by epifluorescence microscopy. An active cellular electron transport system specifically reduces 2-(p-iodophenyl)-3-(p-nitrophen

24. Experimental studies with palygorskite dusts.
As the preliminary results of experimental studies on dust from the palygorskite group have led to some confusion a detailed description of the completed investigation is given for clarification. As in other experiments the biological effects have been shown to be associated with the physical characteristics of the fibres in these specimens. Samples of sepio
