Abstract(s)
O desenvolvimento e produção de petróleo e gás natural é um processo complexo, com várias etapas que depende de diversos fatores de risco. Devido à volatilidade e importância nos mercados internacionais atuais, este processo está sob constante mudança, evolução e desenvolvimento tecnológico. Este trabalho consiste na caracterização química de petróleo proveniente de um reservatório do pré-sal com alto teor de contaminante CO2, para a partir do resultado realizar uma seleção dos melhores materiais a serem utilizados na definição do escopo submarino. Foi realizada também a análise de viabilidade económica deste campo de petróleo para identificar e quantificar os custos associados ao projeto com a inserção da nova tecnologia HISEP® utilizando-se do sistema de produção convencional com Unidade Estacionária de Produção do tipo FPSO, e a modelagem deste sistema de produção petrolífera no software Que$tor. Através do Que$tor, foram estimados o CAPEX e o OPEX de todo o projeto e inventariado discriminadamente cada componente destes custos de acordo com suas naturezas, a fim de se tratar adequadamente as incertezas associadas a estas estimativas através de distribuições probabilísticas. Para obtenção das receitas, foi considerado um valor médio na simulação da evolução de preços do petróleo e os indicadores financeiros como Valor Presente Líquido, Taxa Interna de Rendibilidade, Break Even Point, Payback foram obtidos através do método do fluxo de caixa.
The development and production of oil and natural gas is a complex process, with a lot of stages that depends on several risk factors. Due to the volatility and importance in today's international markets, this process is under constant change, evolution, and technological development. This work consists of chemical characterization of oil from a pre-salt reservoir with a high content of CO2 contaminant and with the result, a selection on the best materials to be used in the definition of the subsea scope was made. An economic feasibility analysis of this oil field was also conducted to identify and quantify the costs associated with the project with the insertion of the new HISEP® technology by using the conventional production system with a Stationary Production Unit of the FPSO type and the modeling of this oil production system in the QUE$TOR software. Through QUE$TOR, CAPEX and OPEX for the entire project were estimated and each component of these costs was inventoried in detail according to their nature, to address the uncertainties associated with these estimates through probabilistic distributions. To obtain the revenues, an average value was considered in the simulation of the evolution of oil prices and the financial indicators such as Net Present Value, Internal Rate of Return, Break Even Point, Payback were obtained through the cash flow method.
