Production optimization for a conceptual model through combined use of polymer flooding and intelligent well technology under uncertainties

Abstract

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.
