O objetivo constitucional de desenvolvimento e o instrumento jurídico-normativo do conteúdo local na indústria petrolífera

On the petroleum industry, the State developed the Local Content police as a regulatory action to guarantee the preference of the national supply industry. Observing that, this paper will analyze the Local Content police aware of the constitutional goal of development as wright in the Constituição Federal de 1988. For it, will be used the hypothetical-deductive method for identifying the Local Content police as State strategy of development turn it in the object of critics in a dialectic way of thinking to in the final, present a conclusion about the police. As result was saw that the existent structure of the police at Brazil is inefficient, claiming for a rebuilt. For conclusion, is said that because of the inadequate construction of the Local Content police created inside of the Agência Nacional do Petróleo – ANP, the efficiency of the full potential of the police is been stopped, something that can be only corrected although a re-make of the police

Avaliação da variação sedimentológica em uma área da plataforma continental sob a atuação da indústria petrolífera

Petroleum exploration activity occurs on the offshore Potiguar Basin, from very shallow (2-3 m) until about 50 m water depth, extending from Alto de Touros (RN) to Alto de Fortaleza (CE). Take in account the biological importance and the heterogeneity of sediments on this area, it is necessary the understanding of the sedimentological dynamics, and mainly the changes generated by petroleum exploration to prevent possible damages to environment. Despite the intense activity of oil exploration in this area, research projects like these are still rare. In view to minimize this gap, this study was developed to evaluate sedimentological, mineralogical and geochemical changes in the vicinity of a exploration well, here designated as well A, located on the Middle continental shelf, near the transition to Outer shelf. The well selected for this study was the first one drilled with Riserless Mud Recovery technology (RMR) in Brazil. The main difference from this to the conventional method is the possibility of drilling phase I of the well with return of drilling material to the rig tank, minimizing fluid and gravel discharging around the vicinity, during this phase. Monitoring consisted of three surveys, first of them done before start drilling, the second one done 19 days after the end of drilling and the third one done one year after then. Comparison of the studied variables (calcium carbonate and organic matter content, sediment size, mineralogy and geochemistry) was done with their average, median and coefficient of variation values to understand the changes after drilling activity. Because operating company technical reasons, the well location was changed after the first survey (C1), resulting in a shift of the sampled area on the two last surveys (C2 e C3). Nevertheless, the acquired data presented a good correlation, with no loss to the mean goal of the study. The sedimentological, mineralogical and geochemical analyzes were done at Federal University of Rio Grande do Norte (UFRN). The results indicated a predominantly sandy environment along the three surveys. It was noticed that the first survey (C1), presented different values for all the studied variables than to the second (C2) and third (C3) surveys, which had similar values. Siliciclastic sediments are prevalent at all surveys, and quartz is the main component (more than 80%). Heavy minerals (garnet, turmaline, zircon and lmenite), rock fragments and mud aggregates also was described. Bioclastic sediments are dominated by coralline algae (more than 45%) and mollusks (more than 30%), followed by benthic foraminifera, bryozoans and worm tubes. More rarely was observed ostracoda and spike of calcareous sponge. Because the low changes of the sediments at the studied area and by the using of RMR method in the drilling, it was possible to conclude that drilling activity did not promote significant alteration on the local sediment cover. Changes in the studied variables before and after drilling activity could be influenced by the changing in the sampling area after survey 1 (C1).

Previsão da Classificação da qualidade dos efluentes da indústria petrolífera com recurso a sistemas inteligentes

O presente trabalho realizou-se na Refinaria de Sines e teve como principal objectivo a utilização de ferramentas oriundas da Área Científica da Inteligência Artificial no desenvolvimento de modelos de previsão da classificação da Água Residual Industrial de acordo com a Legislação em vigor, com vista à minimização dos impactes ambientais e das tarifas aplicadas pela Concessionária (Águas de Santo André) à Refinaria. Actualmente a avaliação da qualidade do efluente é realizada através de métodos analíticos após colheita de uma amostra do efluente final. Esta abordagem é muito restritiva já que não permite actuar sobre o efluente em questão pois apenas pode evitar que, no futuro, uma mistura semelhante volte a ser refinada. Devido a estas limitações, o desenvolvimento de modelos de previsão baseados em Data Mining mostrou ser uma alternativa para uma questão pró-activa da qualidade dos efluentes que pode contribuir decisivamente para o cumprimento das metas definidas pela Empresa. No decurso do trabalho, foram desenvolvidos dois modelos de previsão da qualidade do efluente industrial com desempenhos muito semelhantes. Um deles utiliza a composição das misturas processadas e o outro, utiliza informações relativas ao crude predominante na mistura. ABSTRACT; This study has taken place at the Sines Refinery and its main objective is the use of Artificial Intelligence tools for the development of predictive models to classify industrial residual waters according with the Portuguese Law, based on the characteristics of the mixtures of crude oil that arrive into the Refinery to be processed, to minimize the Environmental impacts and the application of taxes. Currently, the evaluation of the quality of effluent is performed by analytical methods after harvesting a sample of the final effluent. This approach is very restrictive since it does not act on the intended effluent; it can only avoid that in the future a similar mixture is refined. Duet these limitations, the development of forecasting models based on Data Mining has proved to be an alternative on the important issue which is the quality of effluent, which may contribute to the achievement of targets set by the Company. During this study, two models were developed to predict the quality of industrial effluents with very similar performances. One uses the composition of processed mixtures and the other uses information regarding the predominant oil in the mixture.

This work presents the results of a survey in oil-producing region of the Macau City, northern coast of Rio Grande do Norte. All work was performed under the Project for Monitoring Environmental Change and the Influence of Hydrodynamic forcing on Morphology Beach Grass Fields, Serra Potiguar in Macau, with the support of the Laboratory of Geoprocessing, linked to PRH22 - Training Program in Geology Geophysics and Information Technology Oil and Gas - Department of Geology/CCET/UFRN and the Post-Graduation in Science and Engineering Oil/PPGCEP/UFRN. Within the economic-ecological context, this paper assesses the importance of mangrove ecosystem in the region of Macau and its surroundings as well as in the following investigative exploration of potential areas for projects involving reforestation and / or Environmental Restoration. At first it was confirmed the ecological potential of mangrove forests, with primary functions: (i) protection and stabilization of the shoreline, (ii) nursery of marine life, and (iii) source of organic matter to aquatic ecosystems, (iv) refuge of species, among others. In the second phase, using Landsat imagery and techniques of Digital Image Processing (DIP), I came across about 18,000 acres of land that can be worked on environmental projects, being inserted in the rules signed the Kyoto Protocol to the market carbon. The results also revealed a total area of 14,723.75 hectares of activity of shrimp production and salting that can be harnessed for the social, economic and environmental potential of the region, considering that over 60% of this area, ie, 8,800 acres, may be used in the planting of the genus Avicennia considered by the literature that the species best sequesters atmospheric carbon, reaching a mean value of 59.79 tons / ha of mangrove

Adsorção de cobre e cromo utilizando fibra de sisal visando o tratamento da água produzida pela indústria petrolífera

Currently, the oil industry is the biggest cause of environmental pollution. The objective was to reduce the concentration of copper and chromium in the water produced by the oil industry. It was used as adsorbent natural sisal fiber Agave sp treated with nitric acid and sodium hydroxide. All vegetable fibers have physical and morphological properties that enablies the adsorption of pollutants. The basic composition of sisal is cellulose, hemicellulose and lignin. The features are typically found in the characterization of vegetable fibers, except the surface area that was practically zero. In the first stage of adsorption, it was evaluated the effect of temperature and time skeeking to optimize the execution of the factorial design. The results showed that the most feasible fiber was the one treated with acid in five hours (30°C). The second phase was a factorial design, using acid and five hours, this time was it determined in the first phase. The tests were conducted following the experimental design and the results were analyzed by statistical methods in order to optimize the main parameters that influence the process: pH, concentration (mol / L) and fiber mass/ metal solution volume. The volume / mass ratio factor showed significant interference in the adsorption process of chromium and copper. The results obtained after optimization showed that the highest percentages of extraction (98%) were obtained on the following operating conditions: pH: 5-6, Concentration: 100 ppm and mass/ volume: 1 gram of fiber/50mL solution. The results showed that the adsorption process was efficient to remove chromium and copper using sisal fibers, however, requiring further studies to optimize the process.

Metodologia de utilização de dados de sensoriamento remoto em zonas costeiras sob influência da indústria petrolífera

Oil spills in marine environments represent immediate environmental impacts of large magnitude. For that reason the Environmental Sensitivity to Oil Maps constitute a major instrument for planning actions of containment and cleanup. For both the Environmental Sensitivity Maps always need to be updated, to have an appropriate scale and to represent accurately the coastal areas. In this context, this thesis presents a methodology for collecting and processing remote sensing data for the purpose of updating the territorial basis of thematic maps of Environmental Sensitivity to Oil. To ensure greater applicability of the methodology, sensors with complementary characteristics, which provide their data at a low financial cost, were selected and tested. To test the methodology, an area located on the northern coast of the Northeast of Brazil was chosen. The results showed that the products of ASTER data and image hybrid sensor PALSAR + CCD and HRC + CCD, have a great potential to be used as a source of cartographic information on projects that seek to update the Environmental Sensitivity Maps of Oil

Contribuição da Geodésia ao monitoramento costeiro do Litoral Setentrional do Rio Grande do Norte, área de influência da indústria petrolífera

The general objective of this thesis has been seasonal monitoring (quarterly time scale) of coastal and estuarine areas of a section of the Northern Coast of Rio Grande do Norte, Brazil, environmentally sensitive and with intense sediment erosion in the oil activities to underpin the implementation of projects for containment of erosion and mitigate the impacts of coastal dynamics. In order to achieve the general objective, the work was done systematically in three stages which consisted the specific objectives. The first stage was the implementation of geodetic reference infrastructure for carrying out the geodetic survey of the study area. This process included the implementation of RGLS (Northern Coast of the RN GPS Network), consisting of stations with geodetic coordinates and orthometric heights of precision; positioning of Benchmarks and evaluation of the gravimetric geoid available, for use in GPS altimetry of precision; and development of software for GPS altimetry of precision. The second stage was the development and improvement of methodologies for collection, processing, representation, integration and analysis of CoastLine (CL) and Digital Elevation Models (DEM) obtained by geodetic positioning techniques. As part of this stage have been made since, the choice of equipment and positioning methods to be used, depending on the required precision and structure implanted, and the definition of the LC indicator and of the geodesic references best suited, to coastal monitoring of precision. The third step was the seasonal geodesic monitoring of the study area. It was defined the execution times of the geodetic surveys by analyzing the pattern of sediment dynamics of the study area; the performing of surveys in order to calculate and locate areas and volumes of erosion and accretion (sandy and volumetric sedimentary balance) occurred on CL and on the beaches and islands surfaces throughout the year, and study of correlations between the measured variations (in area and volume) between each survey and the action of the coastal dynamic agents. The results allowed an integrated study of spatial and temporal interrelationships of the causes and consequences of intensive coastal processes operating in the area, especially to the measurement of variability of erosion, transport, balance and supply sedimentary over the annual cycle of construction and destruction of beaches. In the analysis of the results, it was possible to identify the causes and consequences of severe coastal erosion occurred on beaches exposed, to analyze the recovery of beaches and the accretion occurring in tidal inlets and estuaries. From the optics of seasonal variations in the CL, human interventions to erosion contention have been proposed with the aim of restoring the previous situation of the beaches in the process of erosion.

Monitoramento da morfologia costeira em setores da bacia potiguar sob influência da indústria petrolífera utilizando geodésia de alta precisão e laser escâner terrestre

The objective of this Doctoral Thesis was monitoring, in trimestral scale, the coastal morphology of the Northeastern coast sections of Rio Grande do Norte State, in Brazil, which is an area of Potiguar Basin influenced by the oil industry activities. The studied sections compose coastal areas with intense sedimentary erosion and high environmental sensitivity to the oil spill. In order to achieve the general objective of this study, the work has been systematized in four steps. The first one refers to the evaluation of the geomorphological data acquisition methodologies used on Digital Elevation Model (DEM) of sandy beaches. The data has been obtained from Soledade beach, located on the Northeastern coast of Rio Grande Norte. The second step has been centered on the increasing of the reference geodetic infrastructure to accomplish the geodetic survey of the studied area by implanting a station in Corta Cachorro Barrier Island and by conducting monitoring geodetic surveys to understand the beach system based on the Coastline (CL) and on DEM multitemporal analysis. The third phase has been related to the usage of the methodology developed by Santos; Amaro (2011) and Santos et al. (2012) for the surveying, processing, representation, integration and analysis of Coastlines from sandy coast, which have been obtained through geodetic techniques of positioning, morphological change analysis and sediment transport. The fourth stage represents the innovation of surveys in coastal environment by using the Terrestrial Laser Scanning (TLS), based on Light Detection and Ranging (LiDAR), to evaluate a highly eroded section on Soledade beach where the oil industry structures are located. The evaluation has been achieved through high-precision DEM and accuracy during the modeling of the coast morphology changes. The result analysis of the integrated study about the spatial and temporal interrelations of the intense coastal processes in areas of building cycles and destruction of beaches has allowed identifying the causes and consequences of the intense coastal erosion in exposed beach sections and in barrier islands

DESLOCAMENTOS POPULACIONAIS PENDULARES EM ÁREAS LIGADAS À INDÚSTRIA PETROLÍFERA NO ESTADO DO RIO DE JANEIRO. BRASIL. 2000

O estudo dos movimentos pendulares de população vem adquirindo importância crescente na medida em que estes se relacionam diretamente com a estrutura e as mudanças que ocorrem na economia e na sociedade. No presente caso, referem-se às transformações ligadas à indústria do petróleo e seus impactos na região Norte Fluminense do estado do Rio de Janeiro. Em decorrência dessas mudanças, emergem novas formas de mobilidade espacial da população, como a pendular (diária/ de curta distância, semanal/ de média distância ou estendida/ de longa distância) para pessoas que trabalham ou estudam em município diferente do de sua residência. Neste sentido, o objetivo geral deste estudo, de caráter exploratório descritivo, é discutir o fenômeno dos deslocamentos pendulares de população como processo de interação espacial. Para tal, visa caracterizar esta nova feição da mobilidade populacional, considerando como indicadores básicos, distância percorrida, áreas de origem e destino, bem como a periodicidade dos deslocamentos segundo o recorte espacial da Organização dos Municípios Produtores de Petróleo (OMPETRO) e limítrofes da Bacia de Campos/RJ. Como objetivo específico, busca traçar o perfil sócio-demográfico dos deslocados diários (em especial para atividades do comércio e serviços) e dos deslocados de maior tempo e distância (aqueles ligados á indústria do petróleo). O presente trabalho integra pesquisas em andamento no Grupo de Estudos Espaço e População (GEPOP) do Departamento de Geografia da Universidade Federal do Rio de Janeiro. Brasil.

Emprego de microscopia de fluorescência para a quantificação microbiana em amostras salinas da indústria do petróleo

Os micro-organismos constituem um grande problema em termos econômicos para a indústria petrolífera. Estes são responsáveis pela produção de substâncias corrosivas e a formação de biofilmes, que causam deterioração dos materiais metálicos. Os principais grupos microbianos presentes em amostras ambientais da indústria do petróleo são as bactérias anaeróbias heterotróficas totais (BANHT) e as bactérias redutoras de sulfato (BRS). Atualmente, a quantificação desses grupos microbianos é realizada através da técnica do Número Mais Provável (NMP) que estima o resultado em aproximadamente 28 dias. Neste trabalho foi otimizada uma metodologia para a microscopia de fluorescência de amostras salinas provenientes de tanques de armazenamento de água/óleo. As condições testadas foram o tipo de óleo de imersão, o tipo de diluente, o volume do corante, o volume da amostra corada e a concentração do fixador (glutaraldeído) numa tentativa de correlacionar com resultados de quantificação de BANHT e BRS através da técnica convencional do NMP. Nesse caso, as células totais foram quantificadas por microscopia de fluorescência utilizando o corante fluorescente laranja de acridina (AO). Verificou-se que houve uma correlação entre os resultados da quantificação de células totais por microscopia de fluorescência e os resultados de BANHT pela técnica do NMP, devido a pouca variação de valores expressos em ambas as quantificações. Entretanto, não foi possível correlacionar os resultados da quantificação de células totais com os resultados de BRS por NMP devido à grande variação dos valores de quantificação de BRS. Na microscopia de fluorescência, foi possível, quantificar os micro-organismos em aproximadamente 30 minutos e através das fotografias, verificou-se ainda que as amostras apresentaram-se nítidas e os micro-organismos com uma boa fluorescência
