Description
Con el fin de mitigar las altas heterogeneidades presentes en los yacimientos y la diferencia de movilidad de los fluidos, la industria petrolera ha desarrollado metodologías y tecnologías a nivel de yacimiento conocidas como métodos de recobro, y a nivel de pozo como el sistema de completamiento inteligente. La inyección de polímero es un método que mejora la eficiencia de barrido con el fin de contactar la mayor cantidad posible de hidrocarburos a los pozos productores, mientras que la tecnología de pozo inteligente permite administrar el flujo de fluidos en el pozo y de esta manera, reducir la producción de agua y los costos que implica. Este trabajo tiene como objetivo estudiar el cambio en el comportamiento de la producción debido a la implementación en paralelo de la inyección de polímero y la tecnología de pozo inteligente por medio de simulaciones de un yacimiento conceptual, gestión de riesgo y análisis de incertidumbre económica y geológica. Así mismo, se estableció la rentabilidad generada como principal criterio de comparación, bajo un régimen fiscal brasilero simplificado. Se verificó el mayor incremento en la rentabilidad del proyecto a causa del uso combinado de ambas tecnologías.
To mitigate high reservoir heterogeneities and fluids mobility differences, oil industry has developed methodologies and technologies like recovery methods at reservoir level, and intelligent completion system at well level. Polymer flooding is a method used to enhance the sweep efficiency in order to lead as much oil as possible to the producer wells, meanwhile the intelligent well technology allows to manage the flow of fluids into the wellbore, thus reducing water production and its costs involved. This work aims to study the behavior change of production due to the implementation in parallel of polymer flooding and intelligent well technology through conceptual reservoir simulations, risk management and geological and economic uncertainty analysis. Furthermore, it was stablished the resulting profit as main comparison criterion, under a simplified Brazilian fiscal regime. It was verified the largest project profit increase due to the combined use of both technologies.
