Implicaciones comerciales de la Diplomacia Petrolera China en el Amazonas ecuatoriano. 2007 - 2013

El presente Estudio de Caso tiene como objetivo analizar en qué medida las dinámicas comerciales de la Diplomacia Petrolera China han convertido a Ecuador en un socio estratégico para la RPCh. El petróleo como fuente de energía es primordial para llevar a cabo los procesos de industrialización y mantener el crecimiento económico del león Asiático. Por eso su búsqueda se ha convertido en un tema principal dentro de la agenda de política exterior. Ecuador, el tercer país de Suramérica con más reservas de petróleo, después de Venezuela y Brasil, se ha convertido en zona de influencia de la RPCh y a través de las empresas petroleras estatales se han firmado contratos por la venta de petróleo. A pesar de que las relaciones bilaterales son asimétricas, se buscar establecer si Ecuador es un socio estratégico en la región.

Utilidad de la relación estratégica comunitaria y el marketing en el sector de extracción de petróleo crudo y gas natural

El presente trabajo pretende investigar y analizar la utilidad de las relaciones estratégicas comunitarias y el marketing en el sector de extracción de petróleo crudo y gas natural. El mercadeo juega un papel importante a la hora de vender cualquier tipo de producto o servicio. Dependiendo de las características de cada sector, las estrategias de mercadeo pueden llegar a ser más o menos útiles y/o efectivas que otras. Por esta razón, esta investigación pretende analizar la utilidad de las estrategias de marketing comunitario y marketing en el sector de extracción de petróleo crudo y gas natural. La forma de llegar a esa respuesta, puede hallarse por medio de tres caminos: el primero de ellos es encontrar y analizar las características del sector, el segundo es identificar cuáles son las estrategias que están utilizando las empresas que operan este campo, y por último, consistiría en analizar la utilidad de integrar el concepto de relación estratégica comunitaria y marketing al sector de extracción de petróleo crudo y gas natural, en cuanto a los beneficios que el marketing comunitario le traería al sector de interés. El sector de petróleo crudo y gas natural es uno de los más importantes en la economía global y sus clientes son numerosos y totalmente heterogéneos. El mercadeo se vuelve muy complejo para esta industria ya que al tener tipos de clientes tan distintos se dificulta alcanzar las expectativas de cada uno de ellos con una misma estrategia y por supuesto la forma de vender un producto es más compleja. Estos factores mencionados anteriormente están generando relaciones entre empresas y clientes totalmente transaccionales de corto plazo, y es ahí donde se cree que la inclusión de mercadeo relacional y estrategias de mercadeo relacional pueden ser de utilidad para el sector, generando desarrollo y beneficios mutuos tanto para clientes como empresas.

Evolución de la oruga o constreñimiento de la mariposa: una mirada al rol económico de China en Sudán. (1999- 2008)

La presente monografía tiene como propósito analizar el rol económico de China en Sudán de 1999 al 2008. Tras su crisis en la década de 1990, se examina el efecto que el rol chino tuvo en los sectores productivos de la economía sudanesa: el textil, el agrícola, el metalúrgico y el petrolero, aun cómo la estabilidad política en el régimen de Omar Al-Bashir en el ámbito político y el conflicto en Darfur como factor social. Como un último objetivo esta investigación, basándose en el trabajo de Mohammed Ayoob, se reevalúa el estatus de Sudán como Estado Tercermundista ilustrándolo a través del uso de la analogía de la metamorfosis de una mariposa.

La guerra de Irak 2003: los interés ocultos de las multinacionales petroleras y su influencia en los miembros permanentes del consejo de seguridad de la ONU

El presente estudio de caso tiene como objetivo mostrar el vínculo que hay entre las multinacionales petroleras y las decisiones que tomaron los cinco miembros permantes del Consejo de Seguridad de la ONU (China, Rusia, Francia, Estados Unidos y Reino Unido) a comienzos del año 2003. Para ello se comparara las posiciones que tomó cada Estado, respecto al proyecto de resolución de la guerra contra Irak, con los intereses de sus multinacionales petroleras. Lo anterior, con el fin de comprobar que debido al gran poder económico que tienen las petroleras, éstas ejercen influencia en las decisiones políticas que toma el Estado y, no solo influyen estatalmente sino que logran permear otros escenarios como el Consejo de Seguridad. Por ello se evaluara el papel que cumple la facultad de veto en la aprobación de resoluciones concernientes a la guerra de Irak.

¿Cómo recobrar el patrimonio petrolero de todos los ecuatorianos? (Otros Temas)

Partiendo de lo que ha sido el manejo de los recursos petroleros en el Ecuador durante los últimos 30 años, el autor presenta una serie de elementos críticos acerca de la política petrolera nacional y señala algunos de los principales elementos que, a nivel de administración, han posibilitado que la mayoría de los beneficios obtenidos del petróleo se queden en manos de las empresas transnacionales en detrimento del Estado. El fortalecimiento de la empresa petrolera estatal, la renegociación de contra tos petroleros y la exigencia a las empresas petroleras para que paguen sus obligaciones, tributarias entre otras, son algunas de las decisiones que, a juicio del autor, las autoridades deben tomar de manera inmediata en aras de proteger el patrimonio petrolero del país.

Determinantes da exploração de petróleo na indústria brasileira

Este estudo analisa os fatores que influenciaram a escolha de empresas de petróleo no Brasil a explorar os blocos licitados pela Agencia Nacional de Petróleo (ANP). Os acordos de Exploração & Produção da ANP definem um Programa Exploratório Mínimo a ser feito no bloco licitado, mas os resultados mostram que em muitos casos esse programa exploratório não foi cumprido. Os resultados empíricos mostram que vários fatores afetam a decisão de perfurar poços, entre elas o bonus final oferecido pelo bloco, a participação da Petrobras e a localização geográfica do bloco. A regulação também teve uma influência importante na exploração de blocos, pela indicação da intensidade de poços a ser perfurados e pela flexibilidade de cessão no controle dos blocos. Os resultados também mostram que novas informações têm um papel importante na decisão de perfuração, especialmente informações sobre o preço do petróleo, o prêmio pago pelo lance vencedor e as atividades prévias de perfurações em blocos vizinhos após a licitação. O estudo utiliza uma amostra de 88 blocos licitados durante as quatro primeiras rodadas de licitações da ANP e a incidência de perfurações de poços nesses blocos entre o período de 1999 a 2009.

O impacto da melhoria de um processo operacional na lucratividade e competitividade: um estudo de caso na subsidiária brasileira de uma empresa do ramo de petróleo

Após uma sequência histórica de ciclos econômicos no Brasil, desde o final da década de 90, o país presencia a abertura do setor do Petróleo ligado à descoberta do pré-sal e o volume imensurável das reservas naturais. Esse marco pôde determinar o início de um dos mais relevantes e diversificados ciclos de industrialização na história econômica do Brasil. Mesmo nesse ramo de negócio, um mercado de gigantes, de multinacionais, de grandes players com estratégias inovadoras e múltiplos know-how's insubstituíveis, é fato conhecido, principalmente para os profissionais dessa seara, que muitas empresas de petróleo possuem inúmeros fatores críticos com urgente necessidade de melhoria. O objetivo principal desta dissertação é fazer inicialmente uma breve análise estratégica e mercadológica da subsidiária brasileira de um grupo multinacional do ramo de Petróleo e Gás especializado em tecnologia de fluidos de perfuração de poços de petróleo, com presença em mais de vinte países. Após imersão no contexto, realizar a análise detalhada de um processo em especial, a primeira vista sem importância, que ao ser estudado, monitorado e mapeado, pôde ser ajustado, redesenhado e implementado, apresentando ganhos substanciais para a corporação relacionados à competitividade e lucratividade.

Sustentabilidade das empresas associadas à REDEPETRO-RN

The present study investigated the management of social, environmental and economic sustainability practices employed by 72 oil companies in Rio Grande do Norte state in Brazil associated to Joint Business Network for Enhancing the Competitive Ability of Suppliers of Goods and Services to the Gas and Oil Industry in Rio Grande do Norte (REDEPETRO-RN). Thus, our investigation aimed to determine the extent to which sustainability practices of companies associated to REDEPETRO-RN are developed through their own efforts or influenced by the Triple Helix interorganizational arrangement (governamental organizations, education and research institutions, and industries). The research instrument used was a questionnaire in order to map and characterize the sustainability practices. The research subjects were business owners and managers. The data collected supported the descriptive, correspondence and correlation analyzes. Were identified a greater emphasis of the companies surveyed in developing sustainability practices and greater economic influence of business organizations in the construction of sustainability status. It was concluded with confirmation of thesis of the REDEPETRO-RN arrangement exhibits the characteristics and functioning of a common Interorganizational Cooperative Arrangement, not those of a triple helix interorganizational arrangement, given that the influences exerted for the development of social, environmental and economical sustainability on the part of teaching and research institutions, and government and business organizations do not interact with one another sufficiently to create a virtuous circle of cooperation among the associated companies. By contrast, the Interorganizational Cooperative Arrangement plays an important role in strengthening the competitiveness of companies affiliated to REDEPETRO-RN, by combining different competencies in an attempt at supporting the adoption of sustainability practices, a role reinforced by the scope of PETROBRAS, which, due to its economic importance, has considerable weight in the managerial decisions of associated companies

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

Análise paramétrica da simulação composicional do processo de Drenagem Gravitacional Assistida por Gás (GAGD)

In Brazil and around the world, oil companies are looking for, and expected development of new technologies and processes that can increase the oil recovery factor in mature reservoirs, in a simple and inexpensive way. So, the latest research has developed a new process called Gas Assisted Gravity Drainage (GAGD) which was classified as a gas injection IOR. The process, which is undergoing pilot testing in the field, is being extensively studied through physical scale models and core-floods laboratory, due to high oil recoveries in relation to other gas injection IOR. This process consists of injecting gas at the top of a reservoir through horizontal or vertical injector wells and displacing the oil, taking advantage of natural gravity segregation of fluids, to a horizontal producer well placed at the bottom of the reservoir. To study this process it was modeled a homogeneous reservoir and a model of multi-component fluid with characteristics similar to light oil Brazilian fields through a compositional simulator, to optimize the operational parameters. The model of the process was simulated in GEM (CMG, 2009.10). The operational parameters studied were the gas injection rate, the type of gas injection, the location of the injector and production well. We also studied the presence of water drive in the process. The results showed that the maximum vertical spacing between the two wells, caused the maximum recovery of oil in GAGD. Also, it was found that the largest flow injection, it obtained the largest recovery factors. This parameter controls the speed of the front of the gas injected and determined if the gravitational force dominates or not the process in the recovery of oil. Natural gas had better performance than CO2 and that the presence of aquifer in the reservoir was less influential in the process. In economic analysis found that by injecting natural gas is obtained more economically beneficial than CO2

Estudo da perda de carga e calor no poço injetor no processo De drenagem gravitacional assistida por vapor (SAGD)

The oil companies in the area in general are looking for new technologies that can increase the recovery factor of oil contained in reservoirs. These investments are mainly aimed at reducing the costs of projects which are high. Steam injection is one of these special methods of recovery in which steam is injected into the reservoir in order to reduce the viscosity of the oil and make it more mobile. The process assisted gravity drainage steam (SAGD) using steam injection in its mechanism, as well as two parallel horizontal wells. In this process steam is injected through the horizontal injection well, then a vapor chamber is formed by heating the oil in the reservoir and, by the action of gravitational forces, this oil is drained down to where the production well. This study aims to analyze the influence of pressure drop and heat along the injection well in the SAGD process. Numerical simulations were performed using the thermal simulator STARS of CMG (Computer Modeling Group). The parameters studied were the thermal conductivity of the formation, the flow of steam injection, the inner diameter of the column, the steam quality and temperature. A factorial design was used to verify the influence of the parameters studied in the recovery factor. We also analyzed different injection flow rates for the model with pressure drop and no pressure drop, as well as different maximum flow rates of oil production. Finally, we performed an economic analysis of the two models in order to check the profitability of the projects studied. The results showed that the pressure drop in injection well have a significant influence on the SAGD process.

Estudo da viabilidade econômica em campos maduros

When it comes to oil and gas in Brazil is almost certain that we are referring to activities in deep waters off the coast of Campos, Rio de Janeiro, the main field of action of PETROBRAS and a small number of multinational oil companies . Since the Law 9.478/97 allows, by means of concessions, that other companies other than Petrobras, to explore and produce oil and gas domestically. Soon it moved, then the private companies that want small and medium-sized businesses to invest in such activities, forming a segment of independent producers, as occurs in other countries. In this context, this work aims at making an economic feasibility study, is currently analyzing how this thread and focus on the factors that contribute to its development as well as those that constitute barriers. To this end, we conducted a survey examining some mature fields that are in production in order to capture cost information in the phases of project, operation and abandonment. The work also presents an analysis of the results obtained in the survey, identifying the costs higher. With the results obtained through the study used economic engineering tools such as NPV and IRR, using a variety of design scenarios, to study the economic viability of these fields. In scenario 4 was set a production of 4.0 m³ / d of oil, which is an expected average production for several of these fields, whose minimum value of a barrel of oil, to enable this field, was $ 55.00, this value well below what was being practiced in the market today.

Análise de Sustentabilidade em Projetos de Instalações de Produção de Petróleo

A proposal for a global analysis of sustainability in projects related in oil facilities is presented. By considering economic, environmental and social aspects in the early stages of design, the suggested method is more comprehensive and can be used to complement the analysis commonly applied in the petroleum industry, such as: Study of Technical and Economic Feasibility; Environmental Impact Assessment and Risk Analysis. Several authors, associations, certification bodies and oil companies suggest different approaches to study sustainability in some specific activities (or industries). In this study, a checklist of significant sustainability aspects for the oil industry (surface facilities) was assembled. In addition, a matrix was developed to assess the sustainability items relevant to these projects. In this work, the checklist interacts with the matrix to perform a "Preliminary Analysis of Sustainability of the Enterprise" (APSE). This method allows the identification of aspects that contribute significantly to global sustainability. From this analysis, which includes economic, social and environmental aspects, is built a report that is used to analyze qualitatively and quantitatively the impact of the sustainability aspects of the project. In this analysis are identified items that strongly influence the economic, social or environmental aspects and evaluated alternatives that can increase the overall sustainability of the project. Finally, the alternatives that can be used to indicate the most sustainable option are identified. This method was applied in a project (design) of a small offshore platform. This case study shows how the APSE can contribute to the identification of sustainability initiatives for the enterprise. The results showed that relevant aspects can contribute decisively to global sustainability. Finally, it was observed that the proposed method can contribute to increased rates of sustainability, even after application of analysis commonly used in these projects

Biodegradação de hidrocarbonetos aromáticos policíclicos: prospecção metagenômica e modelagem computacional 3-D de proteínas

Knowledge of the native prokaryotes in hazardous locations favors the application of biotechnology for bioremediation. Independent strategies for cultivation and metagenomics contribute to further microbiological knowledge, enabling studies with non-cultivable about the "native microbiological status and its potential role in bioremediation, for example, of polycyclic aromatic hydrocarbons (HPA's). Considering the biome mangrove interface fragile and critical bordering the ocean, this study characterizes the native microbiota mangrove potential biodegradability of HPA's using a biomarker for molecular detection and assessment of bacterial diversity by PCR in areas under the influence of oil companies in the Basin Petroleum Geology Potiguar (BPP). We chose PcaF, a metabolic enzyme, to be the molecular biomarker in a PCR-DGGE detection of prokaryotes that degrade HPA s. The PCR-DGGE fingerprints obtained from Paracuru-CE, Fortim-CE and Areia Branca-RN samples revealed the occurrence of fluctuations of microbial communities according to the sampling periods and in response to the impact of oil. In the analysis of microbial communities interference of the oil industry, in Areia Branca-RN and Paracuru-CE was observed that oil is a determinant of microbial diversity. Fortim-CE probably has no direct influence with the oil activity. In order to obtain data for better understanding the transport and biodegradation of HPA's, there were conducted in silico studies with modeling and simulation from obtaining 3-D models of proteins involved in the degradation of phenanthrene in the transport of HPA's and also getting the 3-D model of the enzyme PcaF used as molecular marker in this study. Were realized docking studies with substrates and products to a better understanding about the transport mechanism and catalysis of HPA s
