Modelo petrofísico 3D do Arenito Namorado no Campo de Namorado - Bacia de Campos, RJ

The Namorado Oil Field represents the beginning of the oil exploration in Brazil, in the 70s, and it is still a subject of researches because the importance of this turbidite sandstone in the brazilian oil production. The Namorado’s production level was denominated “Namorado sandstone”, it is composed by turbidite sandstone deposited during the Albian-Cenomanian. In order to define the structural geometry of the main reservoir, geological and geophysical tools like RECON and Geographix (Prizm – Seisvision) softwares were used, and its application was focused on geological facies analysis, for that propose well logs, seismic interpretation and petrophysical calculations were applied. Along this work 15 vertical wells were used and the facies reservoirs were mapped of along the oil field; it is important to mentioned that the all the facies were calibrated by the correlation rock vs log profile, and 12 reservoir-levels (NA-1, NA-2, NA-3, NA-4, NA-5, NA-6, NA-7, NA-8, NA-9, NA-10, NA-11 e NA-12) were recognized and interpreted. Stratigraphic sections (NE-SW and NW-SE) were also built based on stratigraphic well correlation of each interpreted level, and seismic interpretation (pseudo-3D seismic data) on the southeastern portion of the oil field. As results it was interpreted on two- and three-dimensional maps that the deposition reservoir’s levels are hight controlled by normal faults systems. This research also shows attribute maps interpretation and its relationship with the selection of the reservoir attribute represented on it. Finally the data integration of stratigraphic, geophysical and petrophysical calculations lets us the possibility of obtain a detail geological/petrophysical 3D model of the main reservoir levels of “Namorado sandstone” inside the oil/gás field

Análise das respostas de atributos sísmicos dos carbonatos barremiano, albiano e neógeno no campo de Bonito, bacia de Campos - RJ

The Bonito oil field, located on southwest of Campos Basin-RJ, has been explored since 1982. The main reservoir is composed by calcarenites of Quissamã Formation (Macaé Group) from Albian, but two other carbonate levels are present on the field, firsts is Coqueiros Formation (Aptian) and the second Siri Member (Oligo-Miocene). In this context and considering that carbonates reservoirs are a challenge for exploratory geoscientists, since the difficulty on recognize the effective reservoir distribution. This work aim to characterize the geophysical/geological facies based on seismic attributes responses, related to reservoir geometrical distribution, for the tree carbonates intervals on Bonito oil Field. A tree dimensional interpretation of the levels has been developed, based on well cross correlation and a 3D seismic interpretation, resulting on the stratigraphic and structural framework of the field, which showed a NE-SW fault trend controlling the Aptian carbonates reservoirs, and halocnetics structures showing a structural trap on Albian carbonates reservoirs. The definition of the structural/ stratigraphic framework possibly the seismic attributes calculations over the reservoir intervals. To select the best response in comparison with the reservoir distribution, obtained by seismic interpretation, the attributes response were compared with isopachs maps of each carbonate stratigraphic level. The attributes Maximum Amplitude, Maximum Magnitude and Rms Amplitude showed a good answer to reservoir distribution. The Rms Amplitude also showed a good correlation with physical rock properties, like RHOB bulk density, for the Albian and Aptian carbonates, as consequence it is possible make a characterization of reservoir distribution based on seismic attribute answer

Expansão ex vivo de células uroteliais em scaffolds 3D

Malformations and possible damages to the urogenital system can be originated in the embryonic period. Moreover, fire guns, knives and accidents, where there is the disruption of the urethra, also cause these lesions. The objective was to analyze the contribution of tissue engineering in the construction of neo-urethra, developed by bioengineering. We performed an urothelial ex vivo expansion of cells in 3D scaffolds (platelet gel matrix and acellular porcine aorta) to assess the contribution of this technique in the construction of a neo-urethra. Mechanical dissociation was made of the inner wall of 10 North Folk rabbit’s bladder, weighing 2.5 to 3.0 kg. After dissociation the cell content was centrifuged and obtained a pellet of urothelial cells. The pellet was ressuspended in culture medium DMEM F12 and cells were maintained in culture for 15 days. Immunohistochemical analysis characterized the urothelial culture. The cells were then implanted in the scaffold - platelet gel. In a second experiment using aortic porcine acellular matrix were implanted urothelial cells alone and urothelial cells on platelet gel, on the inner wall of the scaffold - aorta, with space for setting bordered by a urethral probe. The complex probe - cells - aorta and probe - cells in platelet gel - aorta, were sealed with suture material and culture were maintained in a humidified 37ºC incubator with 5% CO2 in air for 12 days to subsequent histological analysis of urothelium cell adhesion to the scaffolds. By observation under an optical microscope, we could see the growth of cells in the scaffold platelet gel, from a monolayer in to a three-dimensional structure. In the acellular porcine aortic matrix containing the platelet gel, we could observe a few quantity of urothelial cells adhered. However with the acellular porcine aortic matrix in which was implanted only the urothelial cells, we have obtained adhesion to the wall

Análise geomorfológica e do uso da terra da bacia do Ribeirão Tijuco Preto (SP): subsídio ao planejamento ambiental

Este trabalho teve como objetivo principal analisar a dinâmica geomorfológica, bem como a apropriação humana do relevo, mediante a interpretação de forma integrada dos documentos cartográficos elaborados a partir de técnicas da cartografia morfométrica, geomorfológica e de uso da terra, de forma a subsidiar ações vinculadas ao planejamento ambiental da Bacia do Ribeirão Tijuco Preto (SP). Sob os auspícios da abordagem sistêmica, a partir de uma visão integrada e complexa dos sistemas geomorfológicos, propôs-se a quantificar os atributos das formas de relevo, representando-os cartográficamente com a elaboração das Cartas Morfométricas de Declividade ou Clinográfica (De Biase, 1970 e 1992), de Dissecação Horizontal (Spiridonov, 1981 e adaptações de Mauro et. al.,1991), de Dissecação Vertical (Spiridonov, 1981) e de Energia do Relevo (Mendes, 1993). Também, contemplou-se a cartografia geomorfológica de detalhe, com a elaboração da Carta Geomorfológica (Tricart, 1965), bem como o mapeamento do uso da terra, expresso na Carta de Uso da Terra (Ceron e Diniz, 1966). De forma geral, a análise dos Produtos Cartográficos elaborados, permitiu constatar que a Bacia do Ribeirão Tijuco Preto vem sofrendo o desencadeamento de processos erosivos variados. Tais processos estão associados a uma conjunção de condicionantes, que podem ser apontados pelas variadas condições morfométricas do terreno, o clima quente e úmido reinante, as diferentes litologias aflorantes, a tipologia dos solos, bem como, e, de maneira veemente, a intervenção humana. O condicionante antrópico está majoritariamente representado pela monocultura canavieira e pela urbanização, sendo agentes cruciais no desencadeamento dos processos erosivos existentes e na interferência direta na dinâmica do escoamento fluvial da Bacia do Ribeirão Tijuco Preto.

Avaliação morfológica e morfométrica dos túbulos seminíferos de ratos tratados com o antineoplásico busulfan e suplementados com vitamina b12

O busulfan, um antineoplásico utilizado no tratamento de leucemia mieloide, apresenta como mecanismo de ação a alquilação do DNA, impedindo, portanto, a replicação desse ácido nucleico. Dessa maneira, um dos efeitos adversos desse fármaco consiste em danos aos tecidos de intensa atividade proliferativa, incluindo o epitélio seminífero. A vitamina B12 desempenha um papel importante na síntese de DNA, contribuindo no processo de divisão celular. Portanto, neste estudo, foi proposto avaliar a ação do busulfan sobre o epitélio seminífero de ratos e verificar se as alterações provocadas por esse fármaco são amenizadas pela suplementação com vitamina B12 durante o tratamento. Foi também proposto avaliar o hemograma dos animais a fim de verificar se o suplemento vitamínico minimiza a leucopenia e a trombocitopenia, causadas pelo busulfan. Foram utilizados 25 ratos distribuídos em 5 grupos: grupo controle (GC), grupo busulfan (GB), grupo veículo (GV), grupo busulfan+vitamina (GB/B12) e grupo vitamina (GB12). Os tratamentos foram realizados no período de 10 dias da seguinte maneira: os animais do grupo GB receberam duas doses de busulfan (10 mg/kg) no 1º e 4º dias de tratamento. Os animais do grupo veículo (GV) receberam uma solução contendo polietilenoglicol em duas doses de 0,1 ml/100 g de peso corpóreo, semelhantemente ao grupo GB. Os animais de ambos os grupos receberam doses de salina nos demais dias de tratamento. Os animais dos grupos GB/B12 e GB12 receberam busulfan+vitamina B12 e vitamina B12, respectivamente, no 1º e 4º dias de tratamento. Esses animais receberam vitamina B12 durante os demais dias de tratamento. Os animais do grupo GC receberam solução salina em todos os dias do tratamento. Após o tratamento, os animais foram eutanasiados e, por meio de punção cardíaca, o sangue foi coletado para análise do hemograma... (Resumo completo, clicar acesso eletrônico abaixo)
