Project Description

Several questions of crucial importance to society involve the behavior of two or more fluids within a solid porous medium. Relevant applications include the geologic storage of carbon dioxide to counteract greenhouse gas emissions, land-atmosphere interactions with linkages to global climate processes, geothermal energy processes, hydraulic fracturing, and enhanced oil recovery.

Mechanistic models are relied upon to answer such questions, to make predictions of future states, and to engineer solutions. In the context of these applications, the potential impact of improved mathematical models is broad.

The goal of this project is to use digital rock physics techniques to advance multiscale models for two-fluid flow that are consistent across disparate length scales and resolve the operative physics with higher fidelity than existing models. Recent theoretical, experimental, and computational developments offer the opportunity to improve macroscale models by synthesizing information from different scales to better describe the physics.

The main objective is to execute a set of simulations designed to resolve critical outstanding issues associated with the description of multiphase porous medium flows. The team’s codes efficiently use Titan’s GPUs, and have demonstrated scalability to thousands of nodes on Titan. The project team has the expertise and experience to ensure that simulations will achieve a high level of performance on Summit when it becomes available. The simulation campaign will generate data that cannot be obtained from other sources, and is needed to overcome important modeling challenge.
