RESEARCH HIGHLIGHT

Development of a robust adaptive implicit reservoir simulator for chemical flooding

Currently, the only schemes available for the ASP flooding in industry are IMPES 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.

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

RESEARCH PROJECTS

Project A: Partitioned node model for the viscous fingering simulation

This project aims to develop an algorithm for upscaling the viscous fingering problem. The main goal is to be able to reproduce the oil recovery obtained in floods with adverse mobility ratio, in which the classic model would require extremely fine grids, with coarse grids. The method investigated considers a dual continuum approach to properly represent fingering in multi-contact miscible displacements. The extension of the method for considering also immiscible displacement is in progress. This project will provide simulation tools capable of reproducing coreflood experiments that can be extended to field scale simulation.

Project B: Development of a multipurpose robust reservoir simulator for conventional and unconventional reservoirs

This project aims to develop an adaptive implicit reservoir simulator with advanced gridding features. The fluids can be represented with either the compositional or Black-Oil model. The new simulator considers novel numerical adaptive implicit formulations and up to four phase flow is considered. The embedded discrete fracture method is used to describe the flow in fractures. All important features specific to the unconventional reservoirs are to be considered. The simulator is to be built in a general grid framework for handling different grid types (Cartesian, radial, CPG, and unstructured grids) and gridding features (LGR, DPDP, etc).
