Abstract

We are concerned with the development of modeling codes for GGI/brine flow systems in single and dual porosity porous media incorporating multiphase flow and geo-mechanical effects. The initial development of a multiscale parallel simulator (the UW-team simulator) was funded by the DOE-NETL (project #: DE-NT0004730, Task 9, 2008-2009) that had Prof. Pereira as the PI. The simulator is multiscale in that it is designed such that it adapts itself to the number and type of  available processing cores. Thus, it can make effective use of distinct, state-of-the-science high-performance computers such as the new NSF-funded supercomputer of the UW-NCAR (National Center for Atmospheric Research) partnership that will be available in 2011. The activities proposed here are directly related to the goals of a project under development that will be submitted before April/30/2010 to the DOE-NETL in response to the funding opportunity number DE-FE0000250. If funded by SER this project will be a source of matching funds for the externally funded project. Our goal in this project is to develop new high performance modules for the UW-team simulator. We will consider high performance implementations of multiscale methods for elliptic and parabolic problems, and the development of modules for coupled flow and geomechanics and for multiphase flows in naturally fractured aquifers. The proposers have done solid work in the modeling and numerical simulation of several types of flows in heterogeneous porous media. Their expertise will be employed in the development of the new tools that will allow researchers of UW to model and simulate the injection of CO2 in Wyoming. This is a genuinely interdisciplinary (Applied Mathematics/Computer Science) effort: if approved, this project will provide support for the establishment of a new international collaboration with a group of computer scientists at the Federal University in Juiz de Fora, Brazil.
