O princípio constitucional da eficiência aplicado à outorga e à cobrança da água produzida na exploração petrolífera

Water production is unavoidable during a petrol well s lifetime. The amount of produced water associated with oil varies a lot. It can reach values which account to 50% in volume up to nearly 100%, at the end of the well s economic life. It could be verified that, once the water reaches the productive wells, there must be a management of this produced water. Its destiny is defined after a precise study, after which the best option is chosen between relieving it into the environment, re-injecting it into the producing container or disposing it into non-producing formations. Whichever option is made by the involved professionals, after the necessary analysis, it shall consider, besides the technical and economical aspects, also the alternatives which entail less environmental impact. The purpose of the present research is to conduct a study about the application of the constitutional principle of efficiency on the instruments worked out by the public administration on water management, specifically the water use licence and charging for the use in the management of water resources applicable to water production at the petrol wells. In this attempt, before entering the proper approach of the efficiency of the mentioned instruments, it was necessary not only bring to light the doctrinal perception about the constitutional principle of administrative efficiency, but also make some considerations concerning to the structure of the national water resources management, set by the Federal Constitution (1988) and the federal legislation (9433/97)

Diagnóstico da possível influência da atividade petrolífera em sedimentos de fundo da Bacia Piranhas-Açu, região Baixo Açu/RN

It is located in an area of increasing oil exploration, the region of the Lower Açu is at the mercy of a possible pollution generated by this economic activity, which includes various chemical substances harmful to health, such as metals. This thesis aims to, diagnose the areas of River Piranhas-Açu, a region of the Lower Açu, which are polluted by traces factors and more. In this study, it was determined the concentration of the chemica elements Al, CD, Cr, Cu, Fe, Mn, Ni, P, Pb, V and Zn, through the technique of ICP-OES analysis and the size of sediments and their contents organic matter. Were mapped by GPS, 12 points from collections. The interpretations of the results, together associating that allowed pollution to a possible contamination by oil activity. The results showed tha some regions have low concentrations of cadmium, lead, copper, manganese and zinc unable to promote damage to human health. However, there are places where the concentrations of certain metals chromium, iron and zinc are moderately polluted compared to the results with the reference values of literature and others that are highly polluted by iron. However, due to a greater number of wells in production in those locations, those higher concentrations, it can be suggested a possible influence of oi production in some areas with concentrations of chromium and lead are higher than the rest of the points of monitoring. Moreover, it is observed that the highest levels of metals found in sediment of finer texture and more organic matter content

Petróleo: um contributo para o desenvolvimento em São Tomé e Príncipe

São Tomé Príncipe é um dos países mais pobres do mundo totalmente dependente da ajuda externa. Desde a independência, a 12 de Julho de 1975, o país mergulhou num clima de instabilidade sociopolítica e de pobreza que vem afetando e condicionando o desenvolvimento socioeconómico da sociedade santomense. A fraca capacidade governativa dos dirigentes e a falta de consenso na classe política, as sucessivas quedas de governo, o elitismo e o favoritismo reinante tornam quase impossível que se encontre um caminho consensual para que o país possa efetivamente sair da situação de pobreza em que se encontra e começar a dar passos significativos rumo ao desenvolvimento e ao progresso. Sendo um país com imensos problemas estruturais, que se vão agravando com o passar dos anos, São Tomé e Príncipe é um país extremamente frágil, onde a pobreza atinge a maior parte da população. A instabilidade política e social que se vive no país impede que a classe política nacional seja capaz de chegar a um entendimento para o progresso socioeconómico da nação. São Tomé e Príncipe é um país que dispõe de inúmeras potencialidades naturais, muitas delas continuam a ser mal aproveitadas devido à ausência de uma estratégia concertada que conduza o país ao desenvolvimento. Mas para que aconteça é imprescindível que os órgãos decisores do país sejam capazes de primar por políticas credíveis, transparentes e viáveis, para que o progresso e desenvolvimento tão desejado pela sociedade santomense não seja apenas um sonho. Com a descoberta do petróleo no território santomense, a nação tem depositado todas as suas esperanças na exploração petrolífera e que com a arrecadação das receitas daí provenientes o país começará a trilhar o caminho do desenvolvimento e do progresso.

A questão do petróleo em terras indígenas: uma análise constitucional à luz do desenvolvimento sustentável

Recognizing the need to preserve a national ethnic minority, the Constitution, inspired by the pluralistic values of the Constitutional Law State, stipulated a series of rights and guarantees for the conservation of indigenous cultural singularity, disciplining in article 231 the Indians right to maintain their social organization, customs, languages, beliefs and traditions, as well as safeguarding the rights to the lands they traditionally occupy, and the exclusive use of the wealth existing in them, premise of ensuring their physical and cultural continuity, breaking decisively with the paradigm the assimilation of the Indian national civilization. However, despite the Indian policy of ethnic and cultural preservation, the Constitution allowed the exploitation of minerals in aboriginal territory, incorporated herein hydrocarbons, provided they meet certain predetermined requirements, leaving it to the legislature the discipline of ordinary matter. However, this law has not yet been published, with some projects in the National Congress, leaving thus precluding the indigenous subsurface oil exploration until the enactment of enabling legislation. Meanwhile, this paper carries out an integrated analysis of the constitutional protection of ethnic and cultural uniqueness of indigenous peoples, Convention Nº 169 of the International Labour Organization and the bill presented by Deputy Eduardo Valverde, in an attempt to consolidate sustainable development practices in the sector, through developing a system of social and environmental responsible oil exploration, aligning with national energy needs to maintain a balanced environment and preservation of socio-cultural organization of a minority so weakened and beaten over five centuries of domination

O impacto do pagamento da participação sobre a produção de petróleo e gás natural sobre a renda familiar e a propriedade no Município de Governador Dix-Sept Rosado no período de 1998 a 2004

This scientific study deals about the oil and natural gas production participation payment impact in the county of Governador Dix-sept Rosado, Rio Grande do Norte, between 1998 to 2004, applied to family income and property. To do so, this analysis focus on the ricardian´s theory exposition which merges from the concept of the mineral income, in concern to the legal establishment of royalties. This paper also shows the world evolution oil exploration, inserting Brazil in this scene as a oil and natural gas producter. It identifies the productive site of oil and natural gas in Rio Grande do Norte as the Potiguar Oil Area, characterizing its components in the demographic, physical and social aspects, to reflect in the focus point of observation which is the Governador Dix-sept Rosado county. The participation payment on oil and natural gas is demonstrated in a qualitative analysis both in Brazil as in Rio Grande do Norte. The payments given to the land owners in this federative unity are shown in the period of analysis of this essay. The study tells, based in a field research, the benefaction impact of the payment to the land owners over the income and property. The family income were highly impacted, causing economic social classes change to some land owners. The property had less or none impact. It was found negative externalities as the income utilization to other county uses, not causing a multiplier effect in the studied county. The fact of the not utilization of the properties on productive investments in order to supply the finite characteristic of oil and this source of royalties, contradicts one of the reasons of its establishment which is the payment for its productive exhaustion of a land resource

Dinâmica do uso e ocupação do solo no litoral de Macau-RN no período de 1978 a 2008

This study was developed in the northern coast of the city of Macau, a total area of 88,52 km², located in the State of Rio Grande do Norte. It presents relatively plain surface, with interlaced of streams and gamboas, characterized by contributions of oceanic water, flooding areas of swamps. Altogether, the climatic and topographical conditions provide an ideal environment for the development of saline activity. Inserted in the geologic context of the Potiguar Basin, the region presents favorable conditions for the production of hydro-carbons. It still presents natural conditions for shrimp breeding and artisanal fishing. This work analyzes the transformations occurred in the land use, using air photographs of 1978, Landsat 5 ETM Images of 1988, 1998 and 2008. A secular analyzes was carried through the dynamics of the use of the territory and the transformations occurred in the landscape due to the increment of the productive activities. In the survey of the data for study of the area, it was verified that little alteration occurred in the 30 years. The saline activity that was present since the year of 1978 having an increase of about 5% in thirty years; the shrimp breeding activity that had its presence in the decade of 1990, presented a high growth in the land use, therefore in 1998 it presented 0.45% and currently it presents 6.59%. In the field it was observed that great areas used previously for the saline activity, today it is prepared for shrimp breeding and that the areas of petroleum exploration occupy salt mines, beaches and trays. In 1988 it presented a percentage of 0, 07% and currently it occupies 0.46%, having grown 50% in the last 10 years. Although the variation of the occupation of the area has been little expressive, shrimp breeding showed a growth of 1,200% in only 10 years. In regards to petroleum activity, there wasn t any demonstration of an increasing impact in the land use in the area of study in 26 years of exploration

Potencialidade energética em diferentes extratores e tempos de extração do óleo de pinhão-manso (jatropha curcas l.) em soxletter

The current rhythm of petroliferous exploration is esteem that the existing reserves will be depleted in next the 45 years. Thus being, it has that to study intensely, what it has come to be fact, the alternative power plants, as well as the technologies economically capable to ultilizar them. The potential demand of biodiesel for 2020 is taken in consideration that, in accordance with the International Agency of Energia (AIE), in only eight countries, will jump of 34,7 million tons in 2010 for 133,8 million in 2020, with an increment next to 300%. The tame nut is a producing oil plant with all the qualities necessary to be transformed into oil diesel. Beyond perennial and of easy culture, it presents good conservation of the harvested seed, being able to become great producer of substance cousin as optional fuel source. For these authors, this is a culture that can be developed in the small properties, with the available familiar man power, being plus a source of income for the country properties of the Northeast Region. The objective of this work is to evidence the capacity of oil production of the nut-bellwether, and the quality of extration with hexano and methanol in 6 distinct times.

Caracterização térmica de tubos de explorações petrolíferas em águas profundas

Este trabalho foi realizado devido aos novos desafios existentes na área petrolífera, pois tem-se verificado novas necessidades na transferência de calor em tubagens em águas profundas. Com estes novos cenários de produção em águas profundas, existe a preocupação de garantir o escoamento do produto evitando cenários de obstrução nas tubagens. Os principais problemas aquando da exploração petrolífera prendem-se com a ocorrência de parafinas nas paredes dos tubos bem como a formação de hidratos. É descrito neste trabalho as soluções existentes para a transferência do produto e comparação das mesmas. Numa segunda fase é realizado um modelo matemático para análise térmica das tubagens comparando os materiais isolantes propostos, afim de garantir a temperatura mínima do fluido circulante. De salientar que houve a preocupação de ter em conta uma paragem na exploração do petróleo, por motivos de manutenção por exemplo, e garantir dessa maneira a temperatura mínima do mesmo. Este trabalho propõe soluções de isolamento térmico e discute todos os desafios e problemas existentes.

ROYALTIES DO PETRÓLEO E POLÍTICAS PÚBLICAS DE FOMENTO AGROPECUÁRIO: UMA INTERPRETAÇÃO À LUZ DA “DOENÇA HOLANDESA

O debate atual a respeito da distribuição dos recursos oriundos da exploração petrolífera entre os entes que compõem a federação no Brasil tem trazido à baila a problemática do destino que tem sido dado a esses recursos pelos municípios. Pretende-se analisar essa questão centrando-se na relação entre royalties do petróleo e políticas públicas de fomento agrícola tomando como objeto de análise o município de Quissamã no interior do estado do Rio de Janeiro, uma das maiores rendas per capitas do país em função dos royalties. O artigo objetiva analisar a aplicação desses recursos no setor agrícola à luz do paradigma da doença holandesa. Grosso modo, advoga esse paradigma que a riqueza oriunda dos recursos naturais traria consigo uma série de problemas de mau uso dos recursos públicos e ineficiência político- administrativa. A metodologia utilizada consistiu na avaliação da legislação e documentos oficiais dos programas agrícolas; visita de campo e entrevistas semi-estruturadas com atores envolvidas no processo, bem como a estruturação de dados quantitativos relativos à produção, produtividade e arrecadação do município.  O artigo lança luz sobre a importante questão da aplicação de recursos advindos dos royalties do petróleo na sua relação com as políticas públicas para a agricultura.
