Simulação da recuperação de óleos pesados em modelo de reservatório da bacia Sergipe-Alagoas

Abstract

Coupled with the high demand for oil in contemporary society the idea of oil scarcity is a constant problem faced by the oil industry. A possible solution is the search for increased production of heavy oils in mature fields, which have abundant reserves, through enhanced oil recovery methods. The Bacia Sergipe-Alagoas encompasses several mature reservoirs that show declining production that can be revitalized through these techniques, which can be obtained in a computational way, through simulation, seeking to understand how the real reservoir will behave and circumvent the present uncertainties in reservoir engineering studies. The presente work used data from the Bacia SergipeAlagoas found in the literature and carried out case studies changing different parameters such as recovery method, injection flow, number of wells and injection scheme, thus carrying out the computational simulation, in order to increase the efficiency of the oil recovery factor in the field studied. It was observed the scenarios that presented the best recovery factor for the isothermal and non-isothermal case, for the water injection a value of 49.35% of recovered oil was obtained and in the termal method an oil recovery factor of 66.83%. Both scenarios proved to be economically viable.
