O desafio constitucional da distribuição dos royalties de petróleo da bacia pré-sal para promoção de políticas públicas

The administrative model of the Brazilian State, based on regulation, strives, with the application of the efficiency principle and assessment of economical costs, to give a greater effectiveness to fundamental rights by implementing public policies.The objective of this work is to analyze the role of Oil royalties in the context of the Brazilian State, considering that, being an income gap, they might work as a device that promotes intra/intergenerational justice. By means of a correct and efficient distribution and application in the national region, the royalties constitute financial resources available for implementing public policies that intend to guarantee the fundamental rights; above all, with the discovery of the Pre-salt basin and the indisputable rise in the tax revenues arising from Oil exploration. In the making of this work, the theoretical-descriptive methodology is observed, grounded in a critical-reflexive analysis about Constitutional Law and Oil Law. This work analyzes the administrative model of the Brazilian State, the theory of costs of fundamental rights and the theoretical aspects about royalties, such as: the ethical and economical fundamentals, the distribution and destination of revenues, considering the oil exploration scenario before and after the discovery of the pre-salt basin. it is verified, with the present work, the importance of the creation of a new regulatory framework, and consequently the creation of a sovereign wealth fund, which arises to re-evaluate the application of the current norms of Oil revenue distribution. Still, it is imperative that the mechanisms for controlling the application of royalties are defined in detail, so that those can fully admit the objectives of intra/intergenerational justice. Furthermore, it is emphasized that this process should develop from the efficiency principle viewpoint, as well as the principle of reducing social and regional differences, given that the Oil revenues might be used to ensure fundamental social rights, by implementing public policies that are aligned with the development recommended by the Federal Constitution

Novas fronteiras petrolíferas no Brasil : uma análise da necessidade de nova regulamentação da área do pré-sal sob a ótica constitucional

The Oil industry in Brazil has gone through several stages during the economical, political and social historical process. However, the significative changes have happened in the last fifteen years, due to market opening arising from the relaxation of the state monopoly over the Oil deposits and its derivatives. The edition of the Constitutional Amendment #9, changing the first paragraph of the 177th item of the Federal Constitution, marked the end of a stiffness about the monopoly that the Brazilian state kept in relation to the exploration and research of Oil and Gas. The economical order was fundamental to actualize the idea contained in the #9 Amendment, since its contents has the power to set up measures to be adopted by public power in order to organize the economical relations from a social viewpoint. The new brazilian Oil scenery, called pre-salt, presents itself in a way to amaze the economical markets, in addition to creating a new perspective to the social sector. This work will identify, in this new scenario, the need for change in the legal system. Nevertheless, this subject must not be treated in a thoughtless way: being an exhaustible good, we shall not forget that the future generations also must benefit from the exploration of natural resources recently discovered. The settlement of a new regulatory mark, including the change in the concession contract model to production and sharing is one of the suggested solutions as a bill in the National Congress, in an attempt to ensure the sovereignty of the nation. The constitutionality of a new regulatory mark is questioned, starting from an analysis of the state monopoly, grounding the comprehnsions in the brazilian constitutions, the relevance of the creation of Petrobras for self-assertion of the state about the monopoly of Oil and derivatives, and its posture after the Constitutional Amendment nº 9 (1995), when a company stops having control of the state monopoly, beginning to compete in a fairly way with other companies. The market opening and private initiative are emphasized from the viewpoint of the Constitutional Principles of the Economical and Social Order. The relaxation of the monopoly regarding the exploratory activity in the Federal Constitution doesn't deprive from the Union the ownerships of underground goods, enabling to this federal entity to contract, directly or by concession of exploration of goods, to state-owned or private companies. The existing oil in the pre-salt layer transforms the scenario from very high risk to low risk, which gives the Union the possibility of defining another way of exploring this resources in the best interests of the Public Administration

Educação tecnológica e pré-sal: necessidades e urgências

The purpose of this dissertation is whether the demand for manpower trained in technical school for the sector of Oil and Gas (O&G) is in balance with the offer of that training in the Brazilian education system. The methodology used to obtain such information was based on School Census 2000 and 2008 where data were worked out in order to clarify the numbers of enrollments in secondary technical level demanded by the sector of O&G. The demand for manpower with that qualification as a data source was the 2010-2014 Business Plan Program for Mobilization of the National Oil and Natural Gas (PROMINP). This Program identified the future demand for manpower for the Sector of the O&G until 2014 where the occupational categories are mapped prerequisite training and experience. In order to better understand the object of this study was dome a review of the literature with regard to technical education in Brazil but also the importance of the education to economic growth and the peculiarities of the oil economy in different countries possessors of those mines, or that is, developed and underdeveloped countries. Analysis showed that enrollment in technical education in Brazil had a significant increase between the dates 2000 and 2008. It also don´t bring balance with the characteristic of the dynamics of the productive sectors of the economy mainly due to heating of the economy before the global growth especially in the Construction Industry as well as in the Oil and Natural Gas Engineering and a Naval account of the discovery of oil in the Pre-Salt. Another important aspect is that one of the major problems of qualification of manpower in Brazil is due to a bad quality of the student´s school and high school which makes difficult a good performance in office work and also this ability to learn new functions. The rapprochement between the supply of the education system and the demand for manpower with training mid-level technical support for the sector O&G showed that most technical courses demanded or had no enrollment in 2008, had few enrollment in 15 states with demand expect to occur and those enrollment were unevenly distributed among states. The analysis therefore signalize the needed of a public policy that enables the adequacy of the education system (Secondary Technical Education) to Sector of O&G in terms of enrollment and its distribution between the oil producing states and in relation to technical expertise offered

Educação tecnológica e pré-sal: necessidades e urgências

O objetivo desta dissertação de mestrado é verificar se a demanda de mão-de-obra com formação no ensino médio técnico para o setor de Petróleo e Gás (P&G) está em consonância com a oferta daquela formação no sistema educacional brasileiro. A metodologia aplicada para obter tal informação foi baseada no Censo Escolar 2000 e 2008, em que os dados foram trabalhados de maneira a explicitar o número de matrículas nos cursos de nível médio técnico, demandados pelo setor de P&G. A demanda de mão-de-obra com aquela qualificação teve como fonte de dados o Plano de Negócios 2010-2014 do Programa de Mobilização da Indústria Nacional de Petróleo e Gás Natural (PROMINP). Este Programa identificou a demanda futura de mão-de-obra para o setor de P&G até 2014, onde as categorias ocupacionais mapeadas possuem pré-requisitos de formação e experiência. Com o intuito de entender melhor o objeto deste estudo foi feita uma revisão de literatura no que diz respeito ao ensino técnico no Brasil, como também a importância da educação para o crescimento econômico e as peculiaridades da economia do petróleo nos diferentes países possuidores daquelas jazidas, ou seja, países subdesenvolvidos e desenvolvidos. As análises demonstraram que as matrículas no ensino técnico no Brasil apresentaram um significativo aumento entre as datas de 2000 a 2008. Traz também como característica a desarmonia com a dinâmica dos setores produtivos da economia, devido principalmente ao aquecimento da economia antes da crise mundial de 2008, e a retomada recente do crescimento notadamente no Setor de Construção Civil, bem como no setor de Petróleo e Gás Natural e Engenharia Naval por conta da descoberta de petróleo na camada Pré-sal. Outro aspecto relevante é que um dos grandes problemas da qualificação de mão-de-obra no Brasil se deve a má qualidade do ensino fundamental e médio, que dificulta para o futuro profissional um bom desempenho nas suas funções laborais e na capacidade de aprender novas funções. A aproximação entre a oferta no sistema educacional e a demanda de mão-de-obra com a formação de nível médio técnico para o setor de P&G, demonstraram que a maioria dos cursos técnicos demandados não apresentava matrículas em 2008, ou possuíam poucas matrículas nos 15 estados com demanda prevista, e aquelas matrículas estavam mal distribuídas entre os estados. A análise aponta para a necessidade de uma política pública que possibilite a adequação do sistema educacional (Ensino Médio Técnico) ao setor de P&G, tanto no que se refere ao número de matrículas e a sua distribuição entre os estados produtores de petróleo quanto no que se refere à especialidade técnica oferecida

Economia do petróleo e desenvolvimento: estudo exploratório sobre as perspectivas do pré-sal brasileiro

A pesquisa analisa as possibilidades abertas pela exploração de petróleo na camada pré-sal, avaliando de que maneira a expansão do setor petrolífero poderá acelerar o crescimento econômico brasileiro e contribuir para novas estratégias de desenvolvimento. A hipótese inicial é que o Brasil enfrenta uma restrição estrutural de balanço de pagamentos, que poderá ser amenizada pela diminuição das importações de petróleo e derivados e pelo aumento do valor exportado no setor. Para avaliá-la são resgatados aspectos históricos e geopolíticos relacionados ao petróleo, assim como são tratadas as características microeconômicas dos recursos naturais não renováveis. Também se consideram questões de ordem macroeconômica, como a especialização produtiva da economia brasileira e sua inserção no comércio internacional, discutindo como o desenvolvimento da indústria petrolífera poderá afetá-las. Para tanto, a investigação fundamenta-se na teoria estruturalista e nos modelos de crescimento com ênfase na restrição externa. O trabalho examina ainda os casos da Rússia, Venezuela e México para avaliar a experiência de países exportadores de petróleo. Como contribuição, um modelo de crescimento é utilizado para realizar simulações acerca do Brasil, cobrindo o período 2013-2020 com a formulação de três cenários. A partir dos resultados discute-se que a necessidade de consecução das metas fiscal e de inflação pode desencadear políticas restritivas que limitam a utilização da folga fiscal e externa, oriundas do pré-sal, para induzir o crescimento. Conclui-se que um círculo virtuoso de desenvolvimento com mudança estrutural depende não apenas da modernização produtiva, mas também, e principalmente, da evolução político-institucional do país

Estudo da injeção de água e gás em um reservatório com características do pré-sal brasileiro

The pre-salt province is composed by large amounts of light oil and with good quality, a reality that puts Brazil in a strategic position facing the great demand for energy worldwide. In this province are the largest discoveries in the world in the last ten years; areas as Libra, Franco and Lula field, everyone containing volumes greater than 8 billion recoverable oil barrels. To develop and optimize the production of these fields, a study was done for choosing the improved oil recovery methods. The main motivations were the presence of carbon dioxide (CO2) as a contaminant and the strategic decision of do not discard it, combined with high GOR (gas-oil ratio) of the reservoir fluid. The method should take advantage of the unique abundant resources: seawater and produced gas. This way, the process of matching these resources in the water alterning gas injection (WAG) became a good option. In this master’s dissertation, it was developed a reservoir model with average characteristics of the Brazilian pre-salt, where was applied the improved oil recovery method of water alternating gas. The production of this reservoir was analyzed by parameters as: the first fluid injected in the injection process, position of the injection wells completion, injection water and gas rate and cycle time. The results showed a good performance of the method, with up to 26% of gains in the recovery factor regarding the primary recovery, since the application of water injection and gas, individually, was not able to overcome 10 % of gain. The most influential parameter found in the results was the cycle time, with higher recovery factor values obtained with the use of shorter times.

Avaliação da influência do nacl em pastas de cimento portland para cimentação de poços de petróleo em zonas evaporíticas

One of the major current challenges for oilwell companies is the extraction of oil from evaporitic zones, also known as pre-salt basins. Deep reservoirs are found under thick salt layers formed from the evaporation of sea water. Salt layers seal the flow of oil from underneath rock formations, which store hydrocarbons and increase the probability of success in oil and gas exploration. Oilwells are cemented using Portland-based slurries to promote mechanical stability and zonal isolation. For pre-salt oilwells, NaCl must be added to saturate the cement slurries, however, the presence of salt in the composition of slurries affects their overall behavior. Therefore, the objective of the present study was to evaluate the effect of the addition of 5 to 25% NaCl on selected properties of Portland-based slurries. A series of tests were carried out to assess the rheological behavior, thickening time, free water and ultrassonic compressive strength. In addition, the slurries were also characterized by thermal analysis, X ray diffraction and scanning electron microscopy. The results showed that the addition of NaCl affected the thickening time of the slurries. NaCl contents up to 10% shortened the thickening time of the slurries. On the other hand, concentrations in excess of 20% not only extended the thickening time, but also reduced the strength of hardened slurries. The addition of NaCl resulted in the formation of a different crystalline phase called Friedel´s salt, where free chlorine is bonded to tricalcium aluminate

influência da adição de diferentes sais em pastas de cimento portland para cimentação de poços de petróleo

One of the great challenges at present time related with the materials area concerns of products and processes for use in petroleum industry, more precisely related to the Pre-salt area. Progresses were reached in the last years allowing the drilling of the salt layer, with the time reduction for drilling and larger success at the end. For the oil wells companies the preponderant factor is the technology, however, in spite of the progress, a series of challenges is still susceptible to solutions and one of them refers to the slurries preparation for cementing in those areas. Inside of this context, this study had for objective to analyze the influence of the salts NaCl, KCl, CaSO4 and MgSO4 in strength and chemical structure of the hydrated products. As methodology, they were prepared and analyzed cement slurries with varied concentrations of these salts that are commonly found in the saline formations. The salts concentrations used in formulations of the slurries were of 5%, 15% and 30%. The slurries were formulated with specific weight of 15,8 lb / gal and the cement used was Class G. Strength tests were accomplished in samples cured by 24 hours and 28 days. Also were realized crystallographic characterization (XRD) and morphologic (SEM). In agreement with the presented results, it is observed that the largest resistance values are attributed to the slurries with concentration of 15%. There was reduction of the strength values of the slurries formulated with concentration of 30%. Through the characterization microstructural it was possible to note the salts influence in the main cement hydrated products

Influência da adição do NaCl e KCl em sistemas de pastas contendo sílica para poços de petróleo em zonas evaporíticas e carbonáticas

One of the major challenges faced nowadays by oil companies is the exploration of pre-salt basins. Thick salt layers were formed in remote ages as a consequence of the evaporation of sea water containing high concentrations of NaCl and KCl. Deep reservoirs can be found below salt formations that prevent the outflow of oil, thus improving the success in oil prospection. The slurries used in the cement operations of salt layers must be adequate to the properties of those specific formations. At the same time, their resulting properties are highly affected by the contamination of salt in the fresh state. It is t herefore important to address the effects of the presence of salt in the cement slurries in order to assure that the well sheath is able to fulfill its main role to provide zonal isolation and mechanical stability. In this scenario, the objective of the present thesis work was to evaluate the effect of the presence of NaCl and KCl premixed with cement and 40% silica flour on the behavior of cement slurries. Their effect in the presence of CO2 was also investigated. The rheological behavior of slurries containing NaCl and KCl was evaluated along with their mechanical strength. Thermal and microstructural tests were also carried out. The results revealed that the presence of NaCl and KCl affected the pozzolanic activity of silica flour, reducing the strength of the hardened slurries containing salt. Friedel´s salt was formed as a result of the bonding between free Cl- and tricalcium aluminate. The presence of CO2 also contributed to the degradation of the slurries as a result of a process of carbonation/bicarbonataion

Estudo da injeção de CO2 em reservatórios carbonáticos de dupla-porosidade

As rochas carbonáticas ocupam, numa visão global, um expressivo volume da crosta terrestre. De maneira geral, pode-se dizer que essas rochas estão presentes nas diversas unidades litoestatigráficas da Terra. Os reservatórios carbonáticos são reservas naturalmente fraturadas que exigem uma abordagem diferenciada na modelagem em programas de simulação numérica. Os modelos de dupla porosidade são descritos por funções de tranferências que modelam o fluxo de óleo entre matriz e fraturas. Em um reservatório carbonático naturalmente fraturado o sistema de fraturas é determinante no escoamento de fluidos dentro da reserva. Os maiores reservatórios carbonáticos do mundo estão situados no Oriente Médio e na América do Norte. As maiores reservas de óleo brasileiras encontradas neste tipo de reservatório estão localizadas nos campos do Pré-Sal. No Pré-Sal, um volume significativo de dióxido de carbono é produzido juntamente com o óleo. A disponibilidade de um volume consideravél de dióxido de carbono derivado da produção de óleo no Pré-Sal favorece a utilização dos processos de EOR (Enhanced Oil Recovery) por injeção de gás. O processo de injeção de dióxido de carbono vem sendo utilizado em uma grande quantidade de projetos pelo mundo. A afinidade existente entre o óleo e o dióxido de carbono causa uma frente miscível entre as duas fases causando inchamento e vaporização do óleo dentro do reservatório. Para o estudo, foi utilizado um modelo base de reservatório de dupla-porosidade, desenvolvido pela CMG para o 6° Projeto de Soluções Comparativas da SPE, que modela sistemas de fraturas e de matriz e a tranferência de massa fluida entre elas, características de reservatórios naturalmente fraturados. Foi feita uma análise da injeção de diferentes vazões de dióxido de carbono no modelo base e em modelos semelhantes, com aumento e redução de 5 e 0.5 pontos nas propriedades de porosidade e permeabilidade da matriz, respectivamente, tendo a produção de óleo como resultado. A injeção de 25 milhões de pés cúbicos por dia de CO2 foi a vazão que obteve a melhor fator de recuperação

Análise paramétrica do método de injeção alternada de água e CO2(WAG) em reservatórios de petróleo

After the decline of production from natural energy of the reservoir, the methods of enhanced oil recovery, which methods result from the application of special processes such as chemical injection, miscible gases, thermal and others can be applied. The advanced recovery method with alternating - CO2 injection WAG uses the injection of water and gas, normally miscible that will come in contact with the stock oil. In Brazil with the discovery of pre-salt layer that gas gained prominence. The amount of CO2 present in the oil produced in the pre-salt layer, as well as some reservoirs is one of the challenges to be overcome in relation to sustainable production once this gas needs to be processed in some way. Many targets for CO2 are proposed by researchers to describe some alternatives to the use of CO2 gas produced such as enhanced recovery, storage depleted fields, salt caverns storage and marketing of CO2 even in plants. The largest oil discoveries in Brazil have recently been made by Petrobras in the pre -salt layer located between the states of Santa Catarina and Espírito Santo, where he met large volumes of light oil with a density of approximately 28 ° API, low acidity and low sulfur content. This oil that has a large amount of dissolved CO2 and thus a pioneering solution for the fate of this gas comes with an advanced recovery. The objective of this research is to analyze which parameters had the greatest influence on the enhanced recovery process. The simulations were performed using the "GEM" module of the Computer Modelling Group, with the aim of studying the advanced recovery method in question. For this work, semi - synthetic models were used with reservoir and fluid data that can be extrapolated to practical situations in the Brazilian Northeast. The results showed the influence of the alternating injection of water and gas on the recovery factor and flow rate of oil production process, when compared to primary recovery and continuous water injection or continuous gas injection

A tutela constitucional da exploração de petróleo em águas internacionais em face do princípio do desenvolvimento sustentável: a possibilidade de responsabilização civil do dano futuro

The demands brought by a society doomed to the constant production of global risks, which whose effects are not immediately noticed effects are not perceived immediately, claim from the Law a new Theory about the Risk, that would offer a broad environmental protection, at the same time it would still be compatible with the idea of economic efficiency, required by the Modern Industry. The expansion of the methods and technologies regarding the exploitation and production of oil causes the constant expansion of the exploitable boundaries, especially in ultra-deep waters with the Pre-salt layer, in Brazil, or the still incipient research about the polymetallic nodules and other mineral sources in international waters, like the Atlântico Sudoeste, by the Programme on Ocean Science in Relation do Non Living Resources (OSNLR), a global study performed in partnership with the Intergovernmental Oceanographic Commission, from UNESCO (IOC UNESCO) and also with the Division of Ocean Affairs and Law of the Sea (UNDOALOS). Thus, we aim to analyze the correlation, and possible collisions between the right to a balanced environment and the free exercise of economic activity and the occurrence of environmental damages from the perspective of the exploitation activities of oil and other natural resources in international waters, specifically in the Area, from the constitutional principle of sustainable development and its legitimacy by the environmental international protection. Therefore, this study also aims to evaluate the legal framework for exploration and production of oil in international waters, particularly in the Area, and appraise how the constitutional instruments and mechanisms for environmental protection can impact on the international environmental protection system in order to ensure the present and future generations an ecologically balanced environment, laid down in Article 225 of the Brazilian Constitution, even with so many risks posed by the activities of exploitation and production of oil in international waters. In the meantime, we intend to also intend to investigate the possibility of future liability for environmental damage in order to ensure that constitutional principle and, consequently, and try to define the concept of environmental damage and its implications on the constitutional principle of environmental protection. Given all that was in summary, this work aims to contribute to the evolution of the new Theory of Environmental Risk, turning the law into something more than a punitive or corrective element in this society, but into a legal risk management, that may be triggered even before the consolidation of the damage

Otimização da síntese do AlSBA-15 para produção de biodiesel por transesteri-ficação do óleo de coco

Stimulus encouraging the production and consumption of biodiesel favors the policy of pre-serving the environment, contributing to the reduction of greenhouse gas reducing climate change. The current trend of research in this field focuses on improving these processes with the use of heterogeneous catalysts, seeing has significant advantages such as: low contamination of products, ease of separation of the catalyst from the reaction medium, possibili-ty of reuse of the catalyst, decreased corrosion problems. The objective of this research was to optimize the synthesis of AlSBA-15 for the production of biodiesel through transesterification process via ethyl route. For the optimization of hydrothermal synthesis of type AlSBA-15 catalyst has assembled a 23 factorial experimental matrix with eleven trials. The stoichiometric amounts of starting materials were varied according to different ratios Si / Al which is a factor in the experimental design, in addition to the time and temperature of aging of the synthesis gel. The material showed the best results of characterization (SBET = 591.7 (m2 / g), Vp = 0.83 (cm3 / g), Dp = 5.59 (nm), w = 6.48 (nm) was synthesized at 100 ° C for 24 hours, with a ratio Si / Al = 10.This material was applied as a heterogeneous catalyst in the reaction of ethyl transesterification as raw coconut oil in natura. Coconut oil presented suitable for obtaining biodiesel via ethyl route.The visual aspects and physical-chemical characteristics of the reaction products show that AlSBA-15 catalyst favored the reaction. According to physical-chemical analysis the order of oxidative stability of the product of the transesterification reaction was: catalytic reaction at 1500 ° C> non-catalytic reaction at 100 ° C> 100 ° C catalytic> catalytic reaction at 200 ° C Reaction. The results of oxidative stability and kinematic viscosity shows that the biodiesel produced in the catalytic sandblasting held at 150 ° C which was maintained within the ABNT NBR 7148, ABNT NBR 10441 and EN 14112.
