Characterized as an light oil (28º - 30º API) comparing to the national average, many challenges were overcome to make the exploration economically viable. One of the problems found to produce oil from that region was the high percentage of carbon dioxide (between 8% and 12%), reaching 75% molar in some regions like Júpiter field. The alternative found was to reinject the carbon dioxide from the separation of the natural gás made on own production platform (an FPSO). The reinjection study was realized from the modeling of an light oil, with 8% of carbon dioxide, and an homogeneous oil reservoir, semi-synthetic, with similar characteristics to that region. It was implemented a Project with a time of 35 years and studied the following paramethers: Carbon dioxide flow rate, vertical distance between horizontal rigs used, distance from the rig to the base of the reservoir and the length of the producer rig to the injector rig. After choosing the best scenario, it was realized an analysis of the sensibility related to the injection flow rate reaching a fraction of recovered oil of 64%. In sequence, was realized an economic analysis from two cases: for the first one was admitted the purchase of carbon dioxide from an anthropogenic source and its transport to the platform made by a carboduct. The second case was considered the reinjection of produced gas by the rig from the process of membrane permeation with posterior reinjection. The first one obtained a maximum NPV (Net Present Value) of US$129.885.806,68 and the second one a maximum NPV of US$325.329.657,00. At last, was realized an uncertainty analysis towards the components values of the cash flow for both cases, verifying wich components is more sensitive to the NPV.Acesso AbertoSimulação de reservatórioÓleo leveInjeção de CO2Análise econômicamasterThesisCNPQ::ENGENHARIAS::ENGENHARIA QUIMICA::TECNOLOGIA QUIMICA::PETROLEO E PETROQUIMICA
