Modelo tectono-estrutural dos campos de petróleo Namorado, Cherne e Albacora

The main goal in this research is a tectono-estructural characterization of the Cherne, Albacora and Namorado Fields, located at Campos Basin, in order to investigate the relationship between the geologic evolution and the rock´s physical properties of the reservoir, and how they affect the hydrocarbon accumulation in those fields. Well correlations show that the inferior turbidites have a regional lateral continuity. Basic petrophysics analysis, calculated here, shows that the three fields present porosity values that range from 15 to 20%, shale volume range from 26 to 30% and formation water saturation range from 23 to 45%, based on formation water resistivity dada from Albacora Field. Petrophysics maps feature a trend in Albacora Field that increase the porosity values to SE, and in Cherne and Namorado Field the trend increase towards N. Seismic horizons where interpreted between the first appearance of the Namorado Sandstone and the top of Quissamã Formation. This interval presents normal listric faulting, in Cherne and Namorado Field with NWSE and NE-SW direction, and sedimentation trend to NW-SE, in Albacora Field the faulting presents a NNE-SSW and N-S direction, with a sedimentation trend to NE-SW. Seismic attribute maps present amplitude anomalies close to the producing wells, and on Namorado Field, it indicates a potential hydrocarbon accumulation in the NE region. For each field is indicated laboratory tests for a better characterization of the petrophysical properties, since that they don’t form the same reservoir level, therefore, not influencing the water saturation calculation

Proposta de estruturação do departamento de custos de uma empresa de construção civil de médio porte

This work consists of a literature review of technical project management with a focus on cost management in order to establish concepts and build a theoretical basis for later perform a case study of a construction company. All of the literature review is based on best practices in project management from the Project Management Institute - PMI, among other bibliographies that use the same concepts. The case study covers issues such as area of expertise, constructions undertaken, methodologies, procedures, assumptions, allowing to understand how the company operates in the market and, especially, which interfaces with the cost department in company processes. Confronting the knowledge gained from the literature review of the concepts of PMI and the information obtained from the case study on the current situation of the management costs of the company, it was possible to identify some gaps in the company processes of cost management and thus propose the solution of creating a centralized functional area focused on cost, that is responsible for ensuring that best practices in project management, specifically costs, are being applied

Análise e redução de custos e peso em veículo rodoviário de carga reboque linha de eixos

Load transportation in brazilian territory is made difficult by a deficient highway network, result of low maintenance and lack of government supervision. The problem aggravates when we consider the transportation of indivisible loads, mainly because the brazilian highways are not prepared for such task and few companies in Brazil have the necessary equipment suited for this kind of transport. In this dissertation it will be shown the analysis of a specific equipment to transport overweight indivisible loads, called hydraulic modular multi axle trailer. From an existing project (RB.04LE-01), manufactured and homologated in Brazil, it has been studied how the components in this trailer work so it could have been possible to elaborate a new model (RB.04LE-02), with two main objectives: reduction of costs and weight with subsequent increase in the liquid load for roadway transportation. The trailer’s components analyses were made utilizing the theory of fatigue strength of materials and finite element method with the von Misses criteria for a more safety when realizing the calculations

Caracterização estrutural do Lineamento de Piúma e sua influência na porção norte da Bacia de Campos

The detailed study of the Brazilian continental margin basins became possible with the advancement of geophysical tools, with emphasis on seismic reflection. Characterizing the structural and stratigraphic elements of Brazil’s marginal basins they realized that there was a relationship with structures present on the adjacent continental basement. So many works began to be made to understand this relationship and know the major factors that influenced the evolution of the continental margin. The study area of this work includes the northern portion of the Campos Basin and the continental outcropping adjacent areas, which corresponds to the northern of Rio de Janeiro state and the southern of Espirito Santo state. This area stands an important structural feature of NW-SE direction with a projection to the Campos Basin called Lineamento de Piúma. The outcropping basement rocks belongs to the Ribeira Belt which was bonded to other mobile bands forming the continent Western Gondwana during the Brasiliano Cycle, which later fragmented giving rise to the Atlantic Ocean. The opening of the ocean results on the formation of the marginal basins of Brazil. These basins have continental, transitional and marine facies. On Campos Basin the continental phase resulted on the formation of horsts and grabens bounded by synthetic and antithetic faults. Continuing rifting formed the saline lakes that deposited siliciclastic and carbonate sediments. The transitional phase resulted on thick packages consist of evaporites (halite and anhydrite) that was deposited in lagoon environment, tectonically quiet arid and semi-arid. The marine phase it deposited siliciclastic and carbonate in the Campos Basin resulting in shales, marls, limestones, ritmito, turbidites, sandstones and others. The objective of this study is to investigate the possible continuation... (Complete abstract click electronic access below)

Caracterização geológica e estrutural da porção centro-norte do greenstone belt de Faina, Faina-GO

The area where the study was conducted is located in the central-western state of Goias. It geologically inserts the northern portion of the Greenstone Belt of Faina which belongs to the Archean terranes that fits in Brasília Fold Belt and Tocantins Structural Province. This region is known for its greenstone lode gold potential and it was heavily exploited by pioneers and prospectors, leaving many records for where they have been through. Preliminary work done by Orinoco Brasil Mineração in their required areas at the region showed that the environment is promising for gold mineralization and that the ore is controlled by structures. Therefore the objectives of this work were the geological and structural mapping in semi detail scale to improve geological, stratigraphic and structural controls present attributing possible ore understanding. With the development of the work there were recognized on the desktop three structural domains separated by a thrust fault. For each domain were discriminated the geological units ranging in gneisses, quartzites formed from coarse sediments arcoseanos, and schists. By mapping structures there were found five deformation phases, Dn-2, Dn-1, the Dn event that generated the main foliation (Sn) in high representation and two post-stages Dn with brittle late manifestations. The detail mapping of the Rattlesnake Gallery showed that the mineralized quartz vein is consistent with axial-plane foliation Sn-2 belonging to the oldest deformation Dn-2 phase and that the high grade is distributed in the hinge region folds of the same phase

Uma análise sobre a polêmica entre sentido externo e sentido inetrno na formação do Brasil: a reflexão estrutural e as novas complexidades

Este trabalho tem o objetivo de analisar a polêmica gerada pela publicação de Arcaísmo como Projeto, de Fragoso e Florentino. Apoiados no mercado atlântico como inserção determinante da economia colonial, no papel estrutural do tráfico de escravos na África como nas colônias americanas, na expansão ultramarina portuguesa como projeto social para a manutenção do Antigo Regime, acabando por reproduzir hierarquia desigual e excludente na colônia e apropriando apenas o resultado final do excedente gerado, os autores afirmam que deste conjunto emergem as condições para um circuito interno de acumulação. Mercadores cariocas, a partir da transformação das formas de acumulação ao longo do século XVIII, preenchem os espaços mercantis internos e alçam-se à hegemonia socioeconômica local, apropriando-se de excedentes agroexportadores sem contudo levar estes à ruína, em função da elasticidade da oferta interna, desta forma reiterando a ordem social excludente da colônia, e criando quadros de monopólio para a elite mercantil. Esta proposta será descrita e criticamente apreciada no capítulo 2. Precedendo-a, apresentamos no primeiro capítulo uma leitura da explicação em “formação da estrutura subdesenvolvida brasileira”, em Furtado. Analisamos extensamente sua análise pautando-nos pelos elementos que entendemos serem centrais, a formação de capital e o nível de renda verificados a partir da produção exportadora em cada período colonial, e a possibilidade de desenvolvimento que permitem. A conclusão é uma síntese entre a reflexão estrutural(ista) de Furtado e o isolamento teórico de Fragoso e Florentino, apontando o papel que entendemos para estes no debate após as críticas a sua proposta, assim como propomos a importância das análises clássicas ao entendimento do resultado histórico brasileiro

Caracterização estrutural e funcional da comunidade do costão rochoso da praia da Feiticeira, Ilhabela: contribuição para avaliação de impactos gerados por vazamento de óleo

Costões rochosos são ecossistemas que propiciam o desenvolvimento de comunidades com grande riqueza de espécies e são ambientes de muita importância para a manutenção dos ecossistemas costeiros. Tais ambientes estão extremamente sujeitos a impactos antrópicos, principalmente no que se refere às contaminações por petróleo. O município da Ilhabela concentra o maior número de costões do Estado de São Paulo, e apresenta um notável histórico desses derrames. A fim de contribuir com o monitoramento dos costões da área do Canal de São Sebastião executado pela CETESB, o presente trabalho tem como objetivo central o estudo da estrutura da comunidade do costão rochoso da Praia da Feiticeira, um dos pontos monitorados pela CETESB entre 1993 e 1996. Além da caracterização das variáveis abióticas, a metodologia, com relação as variáveis biológicas, foi dividida em três partes: estudo quantitativo das espécies dominantes da macrofauna séssil encontradas no campo, baseado na porcentagem de cobertura de Chthamalus bisinuatus (Cirripedia), Brachidontes sp. (Bivalvia) e Tetraclita stalactifera (Cirripedia), gerando gráficos sazonais e demográficos. Para aprimorar as comparações entre os dois trabalhos, foi feito o Teste de hipótese para igualdade de proporções, comparando ano a ano as coletas de inverno, que mostrou que as três espécies dominantes obtiveram mudanças de um trabalho para o outro, rejeitando assim a Ho em todas as situações; estudo qualitativo das espécies de macrofauna e macroalgas encontradas dentro da área amostrada. Este levantamento resultou em uma lista de espécies que foi adicionada ao inventário do programa de monitoramento. O índice de similaridade entre os dois trabalhos foi determinado segundo o coeficiente de Sorrensen, que mostrou uma similaridade média entre as comunidades.

Recuperação de resíduos plásticos provenientes dos processos de injeção

The competitiveness among global markets, the constant need for reducing manufacturing costs and also the growing environmental commitments are fueling the development of techniques for recovery residual parts generated by industrial processes. Among the various areas of a company, we highlight those that involve the processing of raw materials derived from oil, such as polymers (resins), which may take centuries to decompose in the environment and also present as a economic and environmentally strategic point. Thus, this study would examine the recovery of waste polypropylene, from the injection process of a major multinational in the field of home appliances through the recycling by a process comprising the milling, extrusion and chipping of waste material. Easy to deploy, this proposal aims to reduce levels negligible disposal (scrap) of these residues as well as the reintegration of the production process into pieces no visual and no structural importance, aimed at cutting costs and reducing environmental impacts caused. After the survey data in kilograms of waste material generated in a given period of time, and the study of changes in material properties, it would enable the reuse steadily in the injection process

Caracterização estrutural da porção central da Bacia de Santos e seu embasamento continental adjacente, através de interpretação de imagens de satélites e geofísicas

The Santos Basin is located in the Brazilian continental margin and includes the coast of Santa Catarina, Paraná, São Paulo and Rio de Janeiro states. Its northern limit is the Campos Basin through the High of Cabo Frio and the southern one with the Pelotas Basin through the Platform of Florianópolis, totaling an area of approximately 350,000 square kilometers in a water depth of 3,000 m. The Paranapanema Lineament has WNW / ESE direction, and extends from the area filled by the Paraná Basin, on the border between the states of Sao Paulo and Parana, lasting up to near the ocean floor along with the fracture zone of Rio de Janeiro. The Capricorn Lineament is a feature inherited from the separation between the continents of Africa and South America, and is the main structural feature NW / SE of the Santos Basin center-south region. These two structures together with other ones with continental origin may be associated with structural features in the sediments from the Santos Basin. This work aims to characterize the structures operating in the central portion of the Santos Basin based on subsurface data in the offshore area (2D seismic) together with data from the surface of the continental basement in a way to correlate the Santos Basin structures with the continental regional traits. This data interpolation showed that the structural features of the continent operates on the submerged zone, the seismic sections show these structural trends for the Paranapanema Lineament / Fracture Zone of Rio de Janeiro, Capricorn Lineament and two fault zones that exhibit structures typical of a transfer zone

Levantamento estrutural da porção norte do Greenstone Belt do rio Itapicuru e dos Alvos Encantado e C1W, Bahia

The study area is located in the geological context of the northern portion of the Rio Itapicuru Greenstone Belt (GBRI), located northeast of the São Francisco Craton, Bahia State. The GBRI is known for its great economic potential for gold mineralization, looking south at Fazenda Brasileiro Mine and North Mine Maria Preta, is situated in the study área. The structural pattern of the northern portion of the Greenstone, theme of this work, is of great importance to understand the mineralization present. To characterize the structural model three geologic sections (scale 1:25000) were made with NW-SE and EW directions and detailing two mineralized targets, Encantado, located northwest of the area, near the city of Nordestina, and C1W, located near Itapicuru River, west of the Maria Preta mine. Thus, field work and petrographic analysis were conducted, that allow to indicate the existence of two structural domains characterized by the existence of a main foliation, low angle dipping main foliation and another with high dip angle, both with NW, moreover, folds occur in the area Dn-1 and post-Dn folds. Dn-1 folds are observed less frequently but they occur mainly forming an oblique foliation and the Sn is present in porphyroblasts observed in petrographic analysis, whereas in relation to the folds post Dn, there are more than one type of folding in area, which differ by the orientation of their axis, a post Dn NS and EW Dn another post. Moreover, two areas of metamorphic green schist (biotite zone) and medium amphibolite, which are directly related to the structural domains found

Are being released in the construction market in Brazil ventures called Super 6. These businesses sell the promise of delivery of the apartment in six months after the launch of the venture. To meet this deadline are being deployed the constructive method of concrete walls using aluminum shapes. This system basically consists of pouring slabs and walls once, i.e. building up the wall shapes and slab joints. On the walls are used cloth, with reinforcements in vain and corners of walls and on these screens are tied the electrical boxes and conduits. For each tower is used the so-called system of half way, i.e. the system so it is sufficient to mount the Middle deck. Using a concrete which can be deformed in the next day you can lift one deck every two days with ready electric and hydraulicsystem, without having to tow the wall doing only minor fixes in the imperfections after concrete. With this system won an incredible speed in the construction of the structure reducing in almost one-third the length of the work. This work aims to compare in terms of cost-benefit of masonry structural systems and this new concrete wall system called Super 6. For this comparison will be used as parameter values used for the achievement of the Enterprise Portal of Roses of constructor Tenda which is one of the first to use concrete wall system. This project basically consists of seven towers of six floors each and will be budgeted the cost of this project if it were held in structural masonry. From these data it will be possible to make a comparison about the actual beneficial to adopt this system

Avaliação mecânica da colagem estrutural entre compósitos poliméricos e materiais metálicos utilizados em dutos petroquímicos

The development of technology for structural composites has as one of its ends form a set of materials that combine high values of mechanical strength and stiffness and low density. Today, companies like Embraer and PETROBRAS and research institutions like NASA, working with these materials with recognized advantages in terms of weight gain, increased performance and low corrosion. We have developed a systematic study to determine the bond strength between composite carbon fiber / epoxy and fiberglass / epoxy laminate both bonded to a carbon steel which are widely used in the petrochemical industry and repair. For morphological evaluation and bonding between materials of different natures, ultrasound analysis, optical microscopy and stereoscopy were performed. To simulate actual conditions, the composites were subjected to conditioning by using heat shock temperatures from -50 to 80 ° C for 1000 cycles for composite carbon fiber / epoxy composites and 2000 cycles for fiberglass / epoxy . The use of composites studied here proved to be efficient to perform repairs in metallic pipes with application petrochemical, as when exposed to sudden changes of temperature (-50 ° to 80 ° C) cycling at 1000 to 2000 times, its mechanical properties (shear and tensile) practically do not change
