Development of a robust adaptive implicit reservoir simulator for chemical flooding - Bruno Ramon Batista Fernandes

The deliverable of this project is a reservoir simulator that can be used as a reliable tool for the history matching and evaluation of field development opportunities, which will impact the value of chemical flooding projects.

Currently, the only schemes available for the alkaline/Surfactant/Polymer (ASP) flooding in industry are Implicit Pressure Explicit Concentration (IMPEC) and Fully Implicit Pressure and fully Implicit Concentration (FI) based. Recently, this project has produced an effective and robust adaptive implicit method for the SP flooding. We are currently extending this scheme for the ASP flooding considering both three phase microemulsion systems and a simplified version of the micellar phase behavior modelling. The deliverable of this project is a reservoir simulator that can be used as a reliable tool for the history matching and evaluation of field development opportunities, which will impact the value of chemical flooding projects. We investigate fluid flow properties and phase behavior models recently developed in the literature, and also propose new models for these that provide proper numerical properties for use in an implicit algorithm. The new developments will provide state of art reservoir simulator, and the techniques developed can be included into current reservoir simulators in industry. Such can make the simulation of chemical flooding in field-scale problems possible, which we hope will encourage the use of these techniques in the field. This development has been supported by the Reservoir Simulation Joint Industry Project at the Center for Subsurface Energy and the Environment.
