Análises tectono-estratigráfica e faciológico-diagenética da coquina-reservatório Lagoa Feia, Campo de Linguado, Bacia de Campos

A tectono-stratigraphic study of bivalve coquina-reservoir of Linguado Field allowed to identify two trends of permoporosity development. The delineation of these depositional-diagenetic traps were made through structural and stratigrafic cross-sections and maps. It resulted in the identification of shelf-ramp systems (tilted to SSE), it tickens from 60 to 70 meters and ends against an antithetic fault. The main coquina is bounded by fine siliciclastic units, white clay (low Gamma Ray values) or shale (high Gamma Ray values) lithologies, influencing diagenesis of basal or top coquina limestones (cimented, non-porous). Also in the middle of coquina-reservoir the “clayer” material is also associated with cemented carbonates, with also compartimentalize the reservoir into two subzones. The coquina porosity of the subzones is taken from density-neutron logs, while induction log estimates permeabilities and fluid saturations. It’s noticed the porosity development into pairs, good one followed by a regular/poor one and vice versa. These pairs form verticals succession, pair cycles where porosity improves or decreases upwards. These two scales of pore heterogeneity impose strong layering to the reservoir, and influences fluid saturations, oil-water contacts and porosity cut-offs. In a cross-section with density and induction logs, it can be observed the porosity variation along the shelf-ramp coquina (between 3LI_0004_RJS e 3RJS_0157C_RJ), the porosity is better developed in a downdip direction in the case of the two shelf wells, and also be the three ramp wells. The southern west downdip, 3RJS_0157C_RJ well, has best porosity pairs-cycles; however, its lowest structural conditions favour water saturation. Therefore it is fundamental for reservoir fluid evaluation a cross-plot analysis of RHOB-NPHI and Induction logs

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

Planejamento ambiental da bacia hidrográfica do córrego Embirí – UGRHI Pontal do Paranapanema – São Paulo: inventário e diagnóstico

This study aimed to contribute to the environmental planning of the watershed Embirí stream - UGRHI Pontal Paranapanema (belonging to the Paranapanema Management unit) in the cities of Presidente Prudente and Regente Feijó, São Paulo. This basin is located in the area of the Santo Anastácio river source, responsible for supplying water to about 30% of the population of Presidente Prudente. The methodological procedures based on Leal (1995) and Rodriguez et al. (2004), and the steps include inventory and diagnosis of the basin. We conducted extensive literature review, cartographic and documentary on the subject area of research, field work, preparation of thematic maps and summary chart of physical units and environmental use and land cover, participatory mapping of environmental risks, quality analysis of water. Most of the basin of the stream of twine had a high environmental fragility and the main problems found were lack of riparian vegetation, erosion, siltation of water bodies, irregular disposal of debris and the dumping of sewage. The results were summarized in the diagnosis and can identify the most important environmental impacts, environmental and spatial weaknesses of the legislation, and thus draw up proposals for action to the area that is substantially degraded

Evolução tectônica do Trend Badejo-Linguado-Pampo, bacia de Campos (RJ)

The regional geological work for the oil industry, in order to find potential areas for hydrocarbon exploration and understand the geological parameters responsible for the formation of the deposit are known importance. This work fits into that scenario, with regional research with the aid of wells and 2D and 3D seismic sold by DBEP (Database Exploration and Production). Were also used as GeoGraphix software package Landmarks modules Prizm and SeisWork 2D and 3D, and the Surfer 8 and ArcGIS 9.2 with the infrastructure provided by the 05 PRH - ANP with LSGI (Laboratory of Seismic and Geological Interpretation) located at UNESP -- Campus de Rio Claro. The work focuses on study the trend of oil-Badejo-Linguado-Pampo, producing fields since the beginning of offshore holdings. The Campos Basin is now known as the offshore basin of the country more productive, and the high structural Badejo is a structure of great importance in the basin presents itself as largely responsible for the conditioning of hydrocarbon fields Pampo, Linguado and Badejo. Therefore this work also aims to increase knowledge of the region in terms of tectonic and stratigraphic characterize the geometry of the structures associated with this major regional structure. For this we used structural contour maps of the main chrono-horizons, and Isopach maps for the purpose of better understanding the tectono-sedimentary evolution of the Campos Basin locally.

Efeitos da ocupação e uso da terra na bacia do córrego da Servidão, no cenário de 1995-2006

Urban sprawl developed without adequate urban planning and lack of knowledge about the physical characteristics of an environmental system, results in soil sealing and consequent change in the dynamics of hydrological watershed. Thus, this study aimed to analyze the behavior of the runoff basin Cóorego DA Servidão located in Rio Claro, referring to the year of 1995 compared to the scenario of 2006, compared the different features of urban use logged area. Therefore understanding the dynamics of the flow was possible through the use of software IPHS 1 that allowed through hydrologic models to evaluate the behavior of the surface area investigated, using Spring 4.3.3 software which enabled the classification of land use and software ArcGis 9.3 which was used for the quantification of stretches of water, separated from those that are channeled and those who did not suffer interference from the pipe

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

Nitrogênio e fósforo na biomassa de Pistia stratiotes Linnaeus em dois ecossistemas lóticos com diferentes níveis de poluição orgânica da bacia do rio Itanhaém, SP

O objetivo desse trabalho foi avaliar as possíveis diferenças no teor de nitrogênio e fósforo na biomassa de Pistia stratiotes, que coloniza um rio com caracterísicas naturais (Aguapeú) e outro, que recebe grande carga de efluentes domésticos (rio do Poço). Para tanto, foram coletadas amostras de água e indivíduos de P.stratiotes (cinco réplicas) nesses rios. Paralelamente foram feitas medidas diretas de variáveis físico-químicas na água (pH, temperatura, condutividade elétrica, salinidade e turbidez). Em laboratório, foram determinados os teores de oxigênio dissolvido e a alcalinidade das amostras de água, bem como as concentrações de nitrogênio orgânico total, nitrogênio orgânico dissolvido, N-amoniacal N-nitrito, N-nitrato, fósforo total, fósforo dissolvido e P-ortofosfato. Os indivíduos de P. stratiotes coletados tiveram o número de folhas, diâmetro da roseta, altura da parte aérea e, o comprimento e volume da raiz medidos logo após a coleta. Esse material vegetal foi separado em biomassa aérea e submersa, seco e moído para a determinação da biomassa e dos teores de nitrogênio e fósforo totais. Observou-se que o rio Poço apresentou anoxia e as maiores concentrações de nutrientes na água. Pistia stratiotes apresentou maior biomassa e teores de nitrogênio e fósforo totais no rio Poço, provavelmente, devido às maiores concentrações de nutrientes deste rio. Por outro lado, a anoxia não foi limitante para o crescimento da espécie nesse rio. A maior proliferação de P stratiotes se deu no rio Poço, em relação ao rio Aguapeú, devido às condições de eutrofização em que se encontra esse ambiente, ocasionada pelo lançamento freqüente de efluentes domésticos, ricos em nutrientes, em seu curso d’água.

Monitoramento hidrossedimentlógico da bacia hidrográfica do alto rio Sucuriú (MS) contribuinte da PCH Costa Rica

The growing demand for electricity in Brazil has stimulated the implementation of Small Hydro Power (PCH) in various regions of the country. However, the silting of reservoirs is a major problem faced by power plants and power plants. In this context, this study aimed to evaluate the data hydrosedimentological strategic points of the watershed of the Alto Rio Sucuriú (MS) to identify the possible causes siltation of the reservoir PCH Costa Rica and suggest mitigation measures. Hydrosedimentological surveys were conducted during the rainy season (February / March 2012) and drought (August 2012), and obtained data flow, discharge liquid, suspended solids and bottom and organic matter content. Based on these results it was determined that the points 2, 4, 7 and 9 are the largest contributors to sedimentation, and point 4 got most liquid discharge (38,20 m3s-1), point 7 largest discharge of solid suspension (906,3 mg L-1), points 2 and 4 major discharges solid totals (231,59 t dia-1 and 238,185 t dia-1 respectively) and point 9 higher organic matter content (22,18%) . Found greater fraction of fine sand and very fine suspended solids and solid medium sand in the background. As mitigation measures for the process of silting of the reservoir PCH Costa Rica (MS) highlights the orientation of landowners in adopting conservation measures and planting of leguminous species native to the region in symbiosis with nitrogen-fixing bacteria

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 da estratégia de controle de enchentes através de reservatórios de detenção de águas pluviais na sub-bacia do Alto Tietê - São Paulo

A rápida expansão do espaço urbano no Brasil ocorreu e continua ocorrendo, geralmente, de forma desordenada e sem perspectivas imediatas de ordenação das práticas de uso e ocupação do solo. O planejamento da ocupação do espaço urbano, baseado na racionalidade capitalista, embora englobe fundamentos interdisciplinares, na prática tem sido realizado dentro de um âmbito mais restrito do conhecimento, desconsiderando aspectos fundamentais dessa dinâmica. Essa situação tem resultado em grandes transtorno e custos para a sociedade e para o meio ambiente, atingindo diretamente os sistemas de drenagens urbanos e resultando no crescimento dos eventos de cheia. Assim, o planejamento urbano vem buscando alternativas que possibilitem o alcance do desenvolvimento urbano sustentável. Neste sentido, este trabalho objetiva avaliar qualitativamente a implantação reservatórios de detenção implantados no alto curso da sub-bacia do Alto Tietê, de modo a avaliar os problemas apresentados através da realização de um inventário dos avanços atingidos na incorporação destas medidas no gerenciamento dos sistemas de drenagem nesta subbacia.
