A presença de uma empresa internacionalmente significa também a disseminação mundial de seu Código de Conduta de Responsabilidade Social (Código de CRS). É portanto necessário um certo controle do conteúdo desses Códigos. As regras e padrões internacionais podem desempenhar este papel. O setor de gás e petróleo causa grande impacto nas comunidades em que as empresas exercem suas atividades. O mesmo se pode afirmar em relação aos seus Códigos de CRS. Este estudo examina, então, duas vertentes distintas mas convergentes. De um lado, o estudo comparativo de como os Códigos de CRS das empresas do setor de gás e petróleo tratam dos aspectos sócio-econômicos. De outro, examina-se a conformidade – ou falta de conformidade – dos Códigos de CRS com os tratados, convenções, normas e padrões internacionais. Estratégias podem então ser propostas ao setor de gás e petróleo, para a melhoria dos padrões sócio-econômicos de seus Códigos de CRS. Com isso atende-se às necessidades das comunidades envolvidas e, também, cria-se valor para as empresas do setor de gás e petróleo.

O presente trabalho de pesquisa, apresentado como dissertação para a conclusão do curso de Mestrado Executivo em Administração de Empresas, teve como objetivo estudar o processo de implantação de um sistema de gestão de integridade de ativos tangíveis na filial brasileira de uma empresa estrangeira com larga experiência no setor de produção de óleo e gás. Embora a empresa matriz esteja presente em inúmeros países, a filial local, chamada neste estudo de Íntegra, é a primeira, fora do país de origem que possui a operação de um campo de petróleo. A análise realizada não foi feita diretamente sobre o processo de implantação do sistema de gestão na prática, mas sim sobre as percepções sobre o tema e os assuntos que este envolve, focando em entender como as partes interessadas entendem a gestão de integridade. O método empregado para o desenvolvimento do trabalho foi o de estudo de caso e a problemática estudada foi a influência dos aspectos culturais e o processo de internacionalização da empresa na implantação dos processos necessários à gestão de integridade de ativos. A fim de reunir material para a elaboração do trabalho, foi realizada pesquisa de campo, onde através de entrevistas com funcionários e prestadores de serviço da Íntegra foram colhidos depoimentos que propiciaram o entendimento da forma como estes viam a condução da implantação de processos na empresa. A confrontação da teoria disponível no meio acadêmico com os dados coletados na pesquisa de campo indicou alguns desafios culturais a serem considerados na implantação do processo de gestão, como os ligados às visões de prazo e aos valores e práticas coletivistas. O trabalho propõe uma discussão especial sobre o papel da liderança para fazer frente a esses desafios.

O Arquipélago da Madeira possui um Património Natural de excepcional valor, rico em Biodiversidade e Geodiversidade, que deve ser conhecido e divulgado internacionalmente, assim como deve ser conservado e preservado para as gerações vindouras. No que respeita à Geodiversidade, a Madeira é dotada de uma variedade geológica de grande interesse, cujo valor cultural, económico e turístico, a torna numa mais valia para a região. Deste modo há que estudar, divulgar e preservar alguns locais de excepcional interesse geológico, elevando-os à categoria de Património Geológico. Neste sentido e no seguimento da política ambiental desenvolvida pelo Governo Regional, traduzida no Decreto Legislativo Regional N.º 24/2004/M de 28 de Agosto de 2004, elaborou-se uma síntese sobre os conceitos de “Património Geológico” e “Geoconservação”, reunindo toda a informação possível sobre o seu enquadramento legislativo, a nível nacional e regional. Sendo a ilha da Madeira de origem vulcânica, foi efectuada uma síntese sobre o Vulcanismo de modo a criar uma base sólida de informação didáctica, tendo em vista a elaboração de documentos de apoio (manuais, brochuras ou painéis interpretativos) destinados ao público que possa visitar este ou outros locais de interesse geológico no Arquipélago da Madeira. Neste âmbito, divulga-se um geossítio, designado por “Cone de Piroclastos da Sr.ª da Piedade”, cujo principal tipo de interesse é simultaneamente vulcanológico e geomorfológico: neste local, os processos de erosão costeira associados à evolução e recuo da arriba litoral actual cortaram, aproximadamente pela metade, um cone de piroclastos basálticos, de morfologia de construção ainda bem conservada, revelando de modo excepcional as condutas alimentadoras, bem como, numerosos aspectos da sua estrutura interna, produtos vulcânicos e etapas de edificação. Tendo como objecto de estudo aquele geossítio, elaborou-se uma ficha de inventariação (PROGEO) e efectuou-se um ensaio de quantificação, de modo que este local seja considerado na estratégia de inventariação e classificação do Património Geológico da Região Autónoma da Madeira.

The natural gas is an alternative source of energy which is found underground in porous and permeable rocks and being associated or not to the oil. Its basic composition includes methane, other hydrocarbon and compounds such as carbon dioxide, nitrogen, sulphidric gas, mercaptans, water and solid particles. In this work, the dolomite mineral, a double carbonate of calcium and magnesium whose the chemical formula is CaMg(CO3)2, was evaluated as adsorbent material. The material was characterized by granulometric analysis, X-ray fluorescence, X-ray diffraction, thermogravimetric analysis, differential thermal analysis, specific surface area, porosity, scanning electronic microscopy and infrared spectroscopy. Then the material was functionalized with diethanolamine (dolomite+diethanolamine) and diisopropylamine (dolomite+diisopropylamine). The results indicated that the adsorbents presented appropriate physiochemical characteristics for H2S adsorption. The adsorption tests were accomplished in a system coupled to a gas chromatograph and the H2S monitoring in the output of the system was accomplished by a pulsed flame photometric detector (PFPD). The adsorbents presented a significant adsorption capacity. Among the analyzed adsorbents, the dolomite+diethanolamine presented the best capacity of adsorption. The breakthrough curves obtained proved the efficiency of this process

This work reports the influence of the poly (ethylene terephthalate) textile surface modification by plasmas of O2 and mixtures (N2 + O2), on their physical and chemical properties. The treatment was carried out in a vacuum chamber. Some parameters remained constant during all treatment, such as: Voltage 470 V; Pressure 1,250 Mbar; Current: 0, 10 A and gas flow: 10 cm3/min. Other parameters, such as working gas composition and treatment time, were modified as the following: to the O2 plasma modified samples only the treatment time was changed (10, 20, 30, 40, 50 and 60 minutes). To the plasma with O2 and N2 only the chemical concentrations were changed. Through Capillary tests (vertical) an increase in textile wettability was observed as well as its influence on aging time and its consequence on wettability. The surface functional groups created after plasma treatments were investigated using X-ray Photoelectron Spectroscopy (XPS). The surface topography was examined by scanning electron microscope (SEM)

This master dissertation presents the study and implementation of inteligent algorithms to monitor the measurement of sensors involved in natural gas custody transfer processes. To create these algoritmhs Artificial Neural Networks are investigated because they have some particular properties, such as: learning, adaptation, prediction. A neural predictor is developed to reproduce the sensor output dynamic behavior, in such a way that its output is compared to the real sensor output. A recurrent neural network is used for this purpose, because of its ability to deal with dynamic information. The real sensor output and the estimated predictor output work as the basis for the creation of possible sensor fault detection and diagnosis strategies. Two competitive neural network architectures are investigated and their capabilities are used to classify different kinds of faults. The prediction algorithm and the fault detection classification strategies, as well as the obtained results, are presented

With the increasing of energetic consumption in the worldwile, conventional reservoirs, known by their easy exploration and exploitation, are not being enough to satisfy this demand, what has made necessary exploring unconventional reservoirs. This kind of exploration demands developing more advanced technologies to make possible to exploit those hydrocarbons. Tight gas is an example of this kind of unconventional reservoir. It refers to sandstone fields with low porosity, around 8%, and permeabilities between 0.1 and 0.0001 mD, which accumulates considerable amounts of natural gas. That natural gas can only be extracted by applying hydraulic fracturing, aiming at stimulating the reservoir, by creating a preferential way through the reservoir to the well, changing and making easier the flow of fluids, thus increasing the productivity of those reservoirs. Therefore, the objective of this thesis is analyzing the recovery factor of a reservoir by applying hydraulic fracturing. All the studies were performed through simulations using the IMEX software, by CMG (Computer Modelling Group), in it 2012.10 version

O capim-camalote (Rottboellia cochinchinensis), originário da Índia, é encontrado em várias regiões do mundo, sendo uma espécie temida pelos agricultores devido ao seu difícil controle e avanço crescente. Objetivou-se com este trabalho estudar os fatores que afetam a germinação das sementes dessa espécie. Foram avaliados os métodos de superação de dormência: 1 - escarificação mecânica, 2 - escarificação química, 3 - tratamento pré-semeadura, 4 - tratamento químico, 5 - tratamento hormonal e 6 - sementes não tratadas. Foram estudados os efeitos da temperatura (5, 10, 15, 20, 25, 30, 35 e 40 ºC), do fotoperíodo (6, 8, 10, 12, 14 e 16 horas de luz), da qualidade da luz incidente (branca, vermelha, vermelha distante, amarela, verde, azul e ausência de luz), da disponibilidade de água (0,0, -0,2, -0,3, -0,4, -0,5, -0,6, -1,2 e -2,4 MPa) e da viabilidade de suas sementes quando armazenadas sob condições de câmara fria e seca e sob condições naturais. Todos os ensaios foram conduzidos por 30 dias em câmara de germinação, com os tratamentos arranjados em delineamento experimental inteiramente casualizado, em quatro repetições. Verificou-se que as sementes apresentaram elevado índice de germinação, praticamente não apresentaram dormência e não se mostraram fotoblásticas. A disponibilidade de água foi indispensável para a germinação, com temperatura ideal de 25 °C. As sementes recém-coletadas são inviáveis para o estudo da germinação, apresentando redução na germinação quando armazenadas sob condição de câmara fria e seca.

The apportionment of natural resources between sovereign States is a subject that relates many aspects of International law, as long as Constitutional Law, at the execution and application phases of international treaties that regulates the exploration of common goods. In this sense, because of their natural characteristics that creates an environment of constant migration and fixation in transboundary regions, terrestrial or maritime, the petroleum and the natural gas bound a complex juridical apparatus that can control the sovereign rights involved. This research is aim at accomplishing a study concerning the international agreements that enable the non-unilateral action, specifically the unitization treaties between sovereign States, as a manner to resolve situations related to the individualization of oil and/or gas reservoirs that go across their national borders. These agreements will be analyzed considering the international public law sources theory, bearing in mind yet the already existed experiences in this sense, not disregarding the way that this fact could affect Brazil. It will begin with an historical incursion over the unitization institute, covering its main characteristics and its formation and execution procedures, and finally it will address the Brazilian legal system and the comparative law threats the institute. The clauses of these relevant agreements will be analyzed in details, concerning its particularities and its contents. Because these agreements are international obligatory rules of law, it is indispensable that they are considered under the auspices of the international law system, focusing their nature and the subjects of international law and establishing them as sources of the international law, analyzing them, then, as international rules and the applicable law to these juridical relations, the conventional established, the consolidated international custom and the applicable International Law principles, appearing the State s responsibility as an important subject for the verification of the acts lawful practiced by States. The analysis of the apportionment of these natural resources ends with the individualization of possible exploitable marine oil fields located between the exclusive economic zone and the continental platform ends and the region administrated by the International Seabed Authority. At last, the Brazilian constitutional system appears as the mechanism of integration, application and execution of the international unitization agreements in Brazil, detaching the format and the proceedings that the international treaties take to acquire validity at the national legal system, passing through the treaties interpretation and the applicable constitutional principles, coming to its application in Brazil, considering the existing constitutional peculiarities and the role played by the National Agency of Petroleum, Natural Gas and bio-fuel ANP

In a country of continental dimensions as Brazil, one of the top challenges to its economic growth is the logistic related to energetical demand supply. We live now in the era of environmental protection and, in this new context of priorizations, it passes trough the search for alternative energies for the energetic matrix, due the petroleum elevated costs in the global market (and its finitude), but also due its pollution over the environment. This attempt of substitution needs solutions related to the national reality, into a national long term developing plan and based at a juridical-economic analysis of its realization. This study will look for, also based in an economical analysis, the juridical legitimity of choosing natural gas as the new protagonist of national economic growth (as a substitute of petroleum) and the necessary boost that must be done by law, based on an economic policy focused strictly for that fact, as a modifying agent of this reality. This study, therefore, will always be turned to a constitutional aspect, respecting the principles of economic order and the goal of reducing regional inequalities, which must influence the making off of a developing plan. At the end, it will try to demonstrate the juridical viability of such undertaking, tuned in jus-economical criteria. Another goal is related to the analysis of the natural gas industry, due the regulation of its transport has a major importance for national energetic integration, not only because this activity be characterized as a net industry, still under control of a natural monopoly, but also because the competitive or cooperative profile that should be priorized at the beginning of the economic planning for this activity (such as investment policies and its own rules that will submit private agents)
