Reservoir Simulators

MPS

The objective of this project is to develop a reservoir simulator with the capability of simulating various recovery processes under one framework. This new simulator is designed to handle miscible gas flooding, chemical flooding, and thermal flooding processes for conventional and unconventional reservoirs. The simulator will also have the capability of executing on parallel computers.  The main goal of the project is development of a unified simulator capable of performing simulations for large complex reservoirs operating under various recovery processes.

UTCHEMRS

UTCHEMRS is a three-dimensional, chemical flooding reservoir simulator capable of modelling up to four-phase flow, namely, an aqueous phase, and oleic phase, a microemulsion phase, and a gas phase. An adaptive implicit method (AIM) with switching criteria based on stability analysis is implemented to improve both time-step size selection and performance. Reservoirs can be discretized using Cartesian and Corner-Point grids. A stable third order high resolution scheme is implemented for Cartesian grids, reducing the need for very fine grids and the effects of grid orientation.

UTCOMPRS

UTCOMPRS is a three-dimensional, EOS Compositional reservoir simulator capable of modelling up to four-phase flow, namely, an aqueous phase, and oleic phase, a gaseous phase, and a second nonaqueous liquid phase. An adaptive implicit method (AIM) with switching criteria based on stability analysis is implemented to improve both time-step size selection and performance. Reservoirs can be discretized using Cartesian, Corner-Point or Unstructured grids. Stable high resolution schemes are also implemented for both Cartesian and Unstructured grids, reducing the need for very fine grids and the effects of grid orientation.
