This thesis is concerned with one aspect of government management regimes for offshore oil and gas - the allocation of rights over these resources. The method by which rights may be acquired, the scope of the rights, and the terms and conditions upon which they are obtained are matters of great significance in determining the overall effectiveness of a management regime. Four coastal nations have been chosen for study. They are the United States of America, the United Kingdom of Great Britain and Northern Ireland, Canada and Australia. The systems adopted by these countries for allocation of offshore oil and gas rights are similar in that they rely mainly upon private enterprise for the development of the resources, but otherwise there are considerable differences. In the first place, the thesis contains a brief statement of the nature and extent of the rights of coastal nations over offshore oil and gas resources at international law. This is to provide the basic framework within which the management regimes of the four countries must operate. Secondly, there is a detailed description of the allocation systems in each of the four countries, with special attention being given to the historical background of the laws which establish the systems, to the provisions of those laws, and to the practical operation of the systems. Finally, there is a comparative assessment of the systems in terms of specific objectives which should form the basis of a government management regime for offshore oil and gas. / Law, Peter A.

The presence of gas and oil in some sand formations decreases the seismic velocity and density to such an extent that anomalously large reflections coefficients are encountered at fluid contacts. Geerstma and Gassmann's theories are equivalent and provide a good way to study the physical properties that affect the elastic behavior of the porous rock. The fluid-contact reflectivity (gas-water, oil-water) can be well estimated based on the brine saturated velocity alone. A comparison between the estimated and observed fluid-contact reflectivities on seismic and well log data from an Offshore prospect showed a remarkable agreement. / text

Os motores elétricos são o elo mais sensível deste equipamento, apresentando baixo MTBF (Mean Time Between Failure), ocasionando intervenções custosas para o seu reparo e/ou substituição nas plataformas off-shore de produção de petróleo. O acionamento da BCS por outro meio é uma alternativa para aumento deste MTBF e a utilização de uma turbina hidráulica como força motriz uma possibilidade já viabilizada tecnicamente. Os produtos existentes no mercado, neste arranjo, BCS+Turbina, são denominados de HSP (Hydraulic Submersible pump). Devido às características construtivas da BCS, múltiplos estágios em série, diâmetro externo reduzido e acoplamento direto com o acionador, o projeto da turbina deve ser alinhado com estes requisitos. Este trabalho investiga a definição da carga de certa BCS bombeando óleo, analisa os diferentes métodos de predição do comportamento desta mesma BCS funcionando como turbina como opção de acionamento, estabelece as condições de projeto deste arranjo, o constrói, o ensaia e compara os resultados com as metolodogias de predição pesquisadas / Abstract: Bore-hole electrical submersible pumps (ESP) are largely used as oil artificial lift alternative. Electrical motor is the most sensitive component of this equipment presenting low MTBF (Mean Time Between Failure) causing high cost operations to fit or replace it on oil production off-shore platforms. ESP driving by another mean is an alternative to increase MTBF and a hydraulic turbine as driver is a technical possibility already available. Market existing products on this arrangement are called HSP (Hydraulic Submersible pump). Due to ESP constructive characteristics like multiple stages, reduced bore-hole diameter and direct coupled to the driver the turbine design should meet these requirements. This work investigates certain SP (Submersible Pump) load when pumping oil and the different prediction methods of this same SP running as turbine as drive option, also establishes the design conditions of this arrangement, builds it, tests it and compares the results against the researched prediction methodologies / Mestrado / Explotação / Mestre em Ciências e Engenharia de Petróleo

The development and production of Canadian offshore petroleum deposits raises three key sets of issues of interest to economists. First are questions relating to the impact of royalties and taxes on producer decisions, and hence on the level and efficiency of resource taxation. Other issues concern the impacts on the overall economy during both the construction and production phases. A third set of issues relates to the distribution of powers and resource revenues between federal and provincial governments, including the links between provincial resource revenues and equalization payments. This thesis develops a numerically tractable economic model designed to examine these issues. At the model's core is a one-to-one relationship between development plans and production profiles. This property is exploited in simulating the behaviour of a price-taking, net-present-value-maximizing producer under conditions of certainty. The model is linked with a macroeconometric model of the Canadian economy to study the potential consequences of Hibernia, a petroleum deposit located in the Eastern Canadian offshore region. This deposit was chosen for analysis because its size, location and low costs (relative to current world oil prices) combine to raise all of the issues listed above. In most cases studied, producer responses to government policies result in the dissipation of less than five percent of the deposit's net present value to society. Although cases are identified where these responses have more serious consequences, the resulting dissipation of potential net benefits never exceeds 15 percent. The extension of specific forms of royalty and tax relief to the producer generally reduces the distortionary effects of government policies. The simulated exploitation of Hibernia induces small but sympathetic changes in most macroeconomic variables. The net crowding-out effects on other industries are shown to be relatively small, and to be more prevalent during the construction period. The results suggest that the larger share of the net benefits accruing to governments flows to the provincial treasury under three of the revenue-sharing systems modelled. However, Newfoundland and Labrador would lose a substantial portion of its Hibernia revenues under all of the equalization systems modelled. / Arts, Faculty of / Vancouver School of Economics / Graduate
