Natural gas markets are incomplete due to physical limitations and low liquidity, but most valuation approaches for natural gas storage contracts assume a complete market. We propose an alternative approach based on indifference pricing which does not require this assumption but entails the solution of a high- dimensional stochastic-dynamic optimization problem under a risk measure. To solve this problem, we develop a method combining stochastic dual dynamic programming with a novel quantization method that approximates the continuous process of natural gas prices by a discrete scenario lattice. In a computational experiment, we demonstrate that our solution method can handle the high dimensionality of the optimization problem and that solutions are near-optimal. We then compare our approach with rolling intrinsic valuation, which is widely used in the industry, and show that the rolling intrinsic value is sub-optimal under market incompleteness, unless the decision-maker is perfectly risk-averse. We strengthen this result by conducting a backtest using historical data that compares both trading strategies. The results show that up to 40% more profit can be made by using our indifference pricing approach.

Este estudo analisa a indústria de gás natural de modo a contribuir para o melhor entendimento acerca das políticas tarifárias da atividade de transporte de gás natural conduzidas pelo governo sob a ótica de um programa de expansão da malha de gasodutos e de fortalecimento da indústria de gás natural no país. A adoção de mecanismos que possibilitem a separação e abertura das parcelas que compõem o preço de venda do gás natural visa a proporcionar uma maior modicidade tarifária, reduzindo os subsídios cruzados entre os Estados (regiões produtoras frente a distantes centros consumidores) e ampliando a eficiência econômica na utilização da malha de gasodutos do sistema de transporte. A partir do auxílio das teorias e modelos tarifários empregados nas indústrias de infraestrutura de rede, a pesquisa analisa a evolução da regulação tarifária associada à Parcela de Produto (Parcela Variável) e à Parcela de Transporte (Parcela Fixa) na formação do preço de venda do gás natural de origem nacional entre a Petrobras e as concessionárias estaduais de distribuição de gás canalizado. A análise dos resultados permite observar que a introdução de mudanças na sistemática de formação do preço de venda do gás natural provoca um retrocesso em relação à transparência na estrutura tarifária e na comercialização do gás natural. A atual política tarifária e os descontos (aproximadamente 32%) praticados pela Petrobras nos preços de venda para as distribuidoras das regiões Nordeste e Sudeste provocam alterações significativas não apenas na competitividade do gás natural frente aos demais combustíveis, mas também dentro do próprio mercado de gás natural. Os consumidores de gás natural nacional não detêm a informação acerca do quanto pagam no custo de serviço de transporte, diferente dos consumidores de gás natural de origem boliviana que se deparam com regras contratuais claras de reajustes dos componentes de cada parcela. Assim, averigua-se que essas mudanças penalizam principalmente os estados com maior produção de gás natural (Rio de Janeiro, Espírito Santo, Bahia e Sergipe), uma vez que o Fator Distância não se encontra claramente definido na nova fórmula de preços do gás nacional. Ainda, conclui-se que o marco regulatório da indústria de gás natural define de maneira clara a formação da tarifa de transporte para os novos gasodutos, enquanto a ANP ainda estuda maneiras de incluir na regulamentação a transparência tarifária na malha de gasodutos existentes. / This study analyzes the natural gas industry in order to contribute to a better understanding of the pricing policies of the activity of the natural gas transmission conducted by the government from the perspective of a program to expand the pipeline network and strengthen the natural gas industry in the country. The adoption of mechanisms that allow the separation and opening of the parcels that make up the selling price of natural gas is intended to provide greater low tariffs, reducing cross-subsidies between states (producing regions across the distant consuming centers) and increasing economic efficiency the use of the gas pipeline of the transportation system. From the aid of tariff models and theories employed in the network infrastructure industries, the research analyzes the evolution of tariff regulation associated with the portion of product (Variable Parcel) and Parcel Transportation (Fixed Parcel) in the formation of the selling price of domestic natural gas rise between Petrobras and the state distribution utilities of gas. The analysis allows us to observe that the introduction of systematic changes in the training of the sales price of natural gas causes a regression in relation to transparency in pricing structure and marketing of natural gas. The current pricing policy and (approximately 32 %) discounts offered by Petrobras in selling prices to distributors in the Northeast and Southeast regions cause significant changes not only the competitiveness of natural gas compared to other fuels , but also within the gas market itself natural. Consumers of domestic natural gas does not hold the information about how much they pay the cost of shipping service, different consumers of natural gas from Bolivian origin faced with clear rules of contractual adjustments of the components of each plot. Thus, it ascertains that these changes mainly penalize states with higher natural gas production (Rio de Janeiro, Espírito Santo, Bahia and Sergipe), since the distance factor is not clearly defined in the new pricing formula of the national gas. Still, it is concluded that the regulatory framework of the natural gas industry defines clearly the formation of the transport charge for new pipelines, while the ANP is also considering ways to include the tariff transparency in the regulatory network of existing pipelines.

In light of developing a nascent gas industry, present multiple challenges in restructuring, regulations and meeting infrastructure investments requirements. To identify an appropriate industry structure and provide suitable regulatory framework to attract adequate infrastructure investments are the requirement to maintain a viable nascent gas industry. The purpose of the study is to examine the conditions required for developing a viable nascent gas industry in Ghana. The study develops an analytical framework by combining the Structure-Conduct-Performance paradigm and the Transaction Cost Economics theory with stakeholder consultation in an integrated cash flow model, which identified inappropriate industry structure, ineffective regulation and high risk as challenges in the gas industry in Ghana. The current gas industry structure and regulatory framework in Ghana is identified as state control monopoly. To strengthen the analysis of the study alternative gas industry structural models were reviewed. The Single Buyer Model (SBM) is suggested as an initial stage structure for Ghana National Petroleum Corporation (GNPC) to commercialize upstream natural gas resources and ease transactions cost. However, the SBM is constrained by the Volta River Authority (VRA) and Electricity Company of Ghana (ECG) inefficiencies. The Multiple Buyer Model (MBM) is considered as a transitional structure to solve the existing hold-up and lock-in inefficiencies of Ghana National Petroleum Corporation-Ghana National Gas Company-Volta River Authority (GNPC-GNGC-VRA) firm structure. Enforcing open access regulations to essential infrastructure is required in the long run. Developing an integrated gas-to-power project in Ghana is a viable business. Nevertheless, non-associated gas production from the Sankofa Gas Project is risky and requires higher gas prices and alternative downstream consumers to be viable. The Gas Processing Plant and transmission pipeline tariffs are inappropriately set and requires regulations. Providing effective regulations and governance arrangements by establishing an independent regulator through a gas sector law are important in protecting the interest of various stakeholders in the nascent gas industry in Ghana.

National oil companies (NOCs) control over 80 percent of world oil reserves and over 50 percent of gas reserves and hold exclusive rights to exploration and development of oil and gas reserves within their home countries. Because of host government involvement and supervision, NOCs may also act as instruments of state, implementing government foreign and domestic policies such as wealth re-distribution through the provision of subsidised oil products, job creation, and economic development. Such activities can lead to restricted availability of funds for finding and developing reserves for future production and to inefficiencies in current production and distribution. This thesis assesses the geopolitical factors that influence the conduct, strategies and priorities of NOCs and how these may impact on the continuing security of energy supplies to countries which are members of the Organisation for Economic Co-operation and Development (OECD). It will focus on ten NOCs supplying oil to world markets and two which supply gas to the European market. The study will also review the activities and .scope for influence as state instruments of Sovereign Wealth Funds which have been established by states with NOCs, in particular, those which have earned substantial petro-dollar surpluses, during the period of high oil and gas prices of2006-2008. In an age of global interdependence between nations, specific objectives of this thesis are to consider the implications of anticipated growth in world demand for oil and gas supplies over the next 20 years, whether world production capacity is likely to grow to meet increases in world demand, the potential impact on world oil and gas supplies of the policies and practices of NOCs, in particular, the desire of host governments to require NOCs to follow non- commercial objectives, and the responses from OECD countries to threats to their energy security from potential restrictions on supplies.

Esta dissertação visa estudar a indústria do gás natural da Venezuela a partir da Teoria Marxista da Dependência (TMD). Mudanças estruturais acontecem nesse país desde o início do século XXI, e esse processo não pode ser entendido sem se observar o papel fundamental da energia. O termo energia refere-se, neste trabalho, ao petróleo e gás natural. O primeiro tem sido o responsável pela penetração do capital estrangeiro no país e o segundo foi historicamente tratado como subproduto da indústria petroleira. A principal mudança nessa perspectiva foi introduzida pelo atual processo político, que usa ambos os recursos como instrumento para superar a relação de subordinação aos países industrializados. Portanto, objetiva-se analisar, com base na TMD, se, dada uma ampliação da indústria do gás natural da Venezuela estarão presentes os elementos capazes de promover uma ruptura com a forma subordinada em que se inseriu o país na economia mundial. Entende-se essa ampliação como um projeto nacional que procura a diversificação da economia e a conquista do desenvolvimento, entendido nos termos expostos pela TMD. Para facilitar o uso da TMD, foram selecionados três de seus expoentes, a saber: Vânia Bambirra, Theotônio dos Santos, e Ruy Mauro Marini. No que concerne à indústria do gás natural, a mesma foi avaliada seguindo parâmetros estabelecidos no Programa de Massificação do Uso do Gás Natural da Petrobras (2004). Por fim, foram contrastados os segmentos da cadeia produtiva do gás avaliados com os parâmetros da TMD, permitindo, por um lado, elucidar o processo que contribuiu para o subdesenvolvimento no país, e, por outro, avaliar o potencial dos atuais planos da IGN para estimular a industrialização nacional e a integração regional. / This document aims to study the Venezuelan natural gas industry using the Marxist Dependency Theory (MDT). Structural changes have been occurring in this country since the early twenty-first century, and those transitions cannot be understood without observing the fundamental energys role. The term \"energy\" refers, in this research, to oil and natural gas. The first one has been responsible for the foreign capital penetration in the country and, the second has been historically treated only as an oil industry derivate. The main change in this perspective was motivated by the current political process, which uses both resources as a tool for overcoming the subordinated relationship with the industrialized countries. Therefore, the objective is to analyze, based on MDT, if an expansion of Venezuela\'s natural gas industry will change the subordinated Venezuelan role in the global economy. This expansion is understood as a \"national project\", which looks for economic diversification and achievement of development, understood in the MDTs terms. To make easier to use the MDT, three exponents was selected: Vania Bambirra, Theotônio dos Santos, and Ruy Mauro Marini. The assessing for the natural gas industry expansion follows the parameters stablished in the National Gasification Program of Petrobras (2004). Finally, the segments of the productive gas chain was contrasted with the MDT parameters, allowing to understand the process that contributed to the country underdevelopment and, evaluating the potential of current plans in natural gas industry for stimulating national industrialization and regional integration.

La thèse discute des conséquences des changements majeurs du modèle de la demande de gaz décrits précédemment. L´exigence de flexibilité à court terme a été l´une des principales caractéristiques de la demande de gaz pour la production d´électricité. Ainsi, la capacité de l´industrie du gaz à fournir des services flexibles à court terme a été valorisée par le biais du marché de l´électricité. Cela signifie une augmentation de la valeur économique des services permettant d´adopter une position attentiste vis-à-vis de la consommation avant toute prise de décision. Différents secteurs de l´industrie du gaz ont été affectés par les variations de la demande, c´est le cas de la production des champs de gaz, du stockage et des mécanismes d´importation du gaz qui ont été incités à la flexibilité. L´introduction des outils de flexibilité, qu’impliquent les variations de la demande, dépend directement des services de réseau. Par conséquent la concrétisation de la valeur économique de la flexibilité de l´industrie gazière dépend des services de réseau.Le réseau de transports de gaz est un élément-clé de l´industrie gazière portant sur deux types de flexibilités physiques: la mobilité et l´aptitude au stockage. Les propriétés physiques du gaz naturel permettent la flexibilité par la gestion des différentiels de pression. Les différentiels de pression contrôlent les mouvements de gaz. Le réseau est de loin le principal mécanisme de transport de gaz et donc un élément majeur de la filière du gaz permettant le commerce de cette matière première. Cependant, le réseau peut aussi être l´une des parties les plus couteuses de l´industrie gazière et, une fois les investissements réalisés ils ne sont ni remboursables, ni récupérables par un autre moyen car ils n'ont pas d’autres utilisations, ce sont les coûts irrécupérables. Malgré cela, la spécificité de le utilisation des actifs des réseaux évolue au cours du développement du réseau.L´intervention des réseaux de transport dans la prestation de services de flexibilité du gaz est une condition obligatoire de la flexibilité du système gazier. Premièrement parce que les services de réseau sont complémentaires de tout autre instrument de flexibilité tels que le stockage souterrain, les infrastructures GNL et le commerce de gaz. Deuxièmement, parce que les services du réseau de transport gazier, tel le que stock en conduite, peuvent également être compétitifs vis à vis d´autres instruments de flexibilité dégroupé.Par conséquent, la régulation du réseau doit prendre en compte l´impact à court et à long terme des règles d´incitation. Compte tenu du fait que le développement du réseau dépend des exigences de flux prévisibles, des variations importantes de la demande de gaz et les changements de flux qui en découlent auront un impact sur l´activité d´exploitation des réseaux gaziers. D´un côté le développement du réseau dépend de la prévision des besoins de flux, et de l´autre, la flexibilité des infrastructures du réseau conditionne nécessairement celle de l´utilisation. Par conséquent, les variations de la demande, responsable de l´accroissement des exigences de flexibilité ainsi que des variations des flux de gaz qui en découlent doivent avoir un impact sur l´exploitation du réseau de gaz et sur l´incitation aux investissements d’infrastructure. / This thesis discusses the consequences of the major changes in gas demand patterns. The requirement of short term flexibility has been one of the main features of electricity generation gas demand. As consequence, the capacity of gas industry to provide short term flexibility services has been valorized through electricity market. It means an increasing economic value to services allowing waiting and seeing before consumption decision. Different parts of the gas industry was impacted by the changes on demand, for instance gas fields productions, storage and gas importation mechanisms were incited to offer flexible provisions. The introduction of tools to provide flexibility required by demand depends on network services. It means the realization of the flexibility value of gas industry depends on gas network services. The gas transport network is the key part of gas industry, and it may provide two kinds of gas physical flexibility: mobility and storability. The physical properties of natural gas allow flexibility by means of pressure differential management. The change on pressures may compress natural gas and the pressures differences drive gas motions. The network has been, by far, the main mechanism to carry gas, thus an essential part of the gas industry chain to allow commodity trade. Network, however, may be one of the most expensive parts of gas industry, and, after the investment done, it becomes sunk costs. But the specificity of networks assets changes in the course of network development. The use of transport network in the provision of gas flexibility services is a necessary condition to provide flexibility in the gas system. First, because network services are complementary of any other flexibility tool, as underground storage, LNG infrastructures and gas trade. Second, because gas transport network services, as line-pack storage, may also be competitive to the others unbundled flexibility tools. Therefore, network regulation needs to take into account the short and the long term impact of the rules incentives. Given that network development depends on expected flow requirements, strong change on gas demand and the consequent changes on gas flows must impact gas network operation. On the one hand, network development depends on expected flow requirements, and on the other, provisions of flexibility depend necessarily on the flexible use of network infrastructures. Hence, changes on gas demand increasing flexibility requirements and the consequent changes on gas flow must impact gas network operation and must impact the incentive on infrastructures investment.

The superation of this first step by the reader will lead to an important perception of the title: that the situation requires, urgently, a defined posture, a complete conduct change and, therefore, a modification of the paradigms currently establisheds. To brake barriers, modifying what is lived by, is the ultimate goal. For that, there is no unique path, linear, but there were broached the development themes, the hidrical resources theme and oil and natural gas industry at the necessary points to achieve, by the end, a comprehension for the Brazilian Federal Republic goals in the search for the application of these juridical norms. The ones whom lay down over this study shall notice that, more than a simple approach over these themes (which are still less worked and searched in Brazil), the heavy critic of an instituted and pacifically accepted reality, directly offensive of the constitutional principles. The debate evolves from punctual and specific aspects, it gains life, flies, searching how the juridical order equalizes the economic model to the environment defense. Standing by the possibility of conciliation among constitutional principles, the remodeling of an economic segment is defended, aligning it to the sustainable limits. Development, sustainable, becomes means and goals to the implementation of liberty, capacitating everyone to achieve their goals of life, their libertments, fruit of the inherent antagonism of the Constitution the sustainable development offers, while an axiological vector, a new reality to the economic order, turning it into a motriz element to the fortification of constitutional normative force and for the national development / Como se deduz do t?tulo firmado para este trabalho O princ?pio constitucional do desenvolvimento sustent?vel e a utiliza??o de recursos h?dricos na ind?stria do petr?leo as p?ginas transcritas dedicam-se a abordagem dos assuntos mencionados que, aparentemente d?spares, mostrar-se-?o visceralmente interligados no transcorrer do estudo.

The goal of this paper is to analyze the factors that lead to the success of new products through the evaluation of the activities done during the process of development of these products in the Natural Gas sector. To achieve this goal a case study was done in a small company of this segment. At first, as a basis for the study, a bibliographical research was done with books, theses, dissertations, monographies, publications in national and international periodicals, congress annals and publications in the internet related to the subject. Afterwards, a case study was done, aiming at the acquisition of further knowledge about the real process of development of products in a small company of the Natural Gas sector, allowing for the performance of the evaluation. The case study was done at Gas Project and Systems do Brasil, a company that works with the development of electronic equipment to the conversion of car engines to natural gas, through direct observations and interviews with the person responsible for the development and management of products. Through the evaluation of the process it was observed that the activities related to it are done in an informal way and some activities are considered unnecessary for their success. The results also suggest an emphasis in the technological activities, something that was not observed in the activities related to the market. The instruments used in this evaluation prove to be efficient to evaluate the process of development of new products in other companies, including those of different areas. Taking into account the relevance of the studied theme to the strengthening of the Natural Gas industry, it is necessary to do further complementary studies / O presente estudo apresenta-se como uma contribui??o ? solidifica??o da Ind?stria de G?s Natural, no ?mbito do desenvolvimento de novos produtos. O objetivo deste trabalho foi analisar os fatores que conduzem ao sucesso de novos produtos, atrav?s da avalia??o das atividades realizadas durante o processo de desenvolvimento desses produtos, no setor de G?s Natural. Para atingir tal objetivo, foi realizado um estudo de caso em uma pequena empresa deste segmento. Para fundamentar o estudo, foi realizada, inicialmente, uma pesquisa bibliogr?fica em livros, teses, disserta??es, monografias, artigos em peri?dicos nacionais e internacionais, anais de congressos, publica??es dispon?veis na internet, relacionadas ao tema de interesse. Posteriormente, foi realizado o estudo de caso visando obter um maior conhecimento sobre um processo real de desenvolvimento de produtos, em uma pequena empresa, no setor de G?s Natural, permitindo a realiza??o da avalia??o. O estudo de caso foi realizado na Gas Project & Systems do Brasil, empresa que atua no desenvolvimento de equipamentos eletr?nicos para convers?o automotiva em G?s Natural, a partir de observa??es e entrevistas com o respons?vel pelo gerenciamento e desenvolvimento de produtos. A empresa em estudo ? a ?nica do Nordeste a fabricar equipamentos que comp?em o kit de convers?o. Atrav?s da avalia??o do processo foi observado que as atividades a ele relacionadas s?o realizadas de maneira informal e algumas delas s?o consideradas desnecess?rias para o sucesso dos mesmos. Os resultados sugerem, tamb?m, uma ?nfase nas atividades tecnol?gicas, o que n?o foi observado para as atividades ligadas ao mercado. Os instrumentos utilizados para esta avalia??o mostram-se eficientes para avaliar o processo de desenvolvimento de novos produtos em outras empresas, inclusive de diferentes ?reas. Diante da relev?ncia do tema em estudo para o fortalecimento da Ind?stria de G?s Natural, faz-se necess?ria a realiza??o de estudos posteriores que o complementem
