Abstract

This proposal outlines a three-year research project to quantify uncertainty related to injection of CO2 into saline aquifers. The activities proposed here are in immediate conjunction with a research proposal to be submitted before April 30, 2010 to the DOE-NETL (DE-FE0000250). Upon successful application, the funds requested in this proposal will be designated as matching funds for the externally funded project. Our main goal in this proposal is to develop a reliable framework for predictive simulation and uncertainty quantification of CO2 injection. Our thesis is that, for a wide range of applications, the ideal situation is to integrate available static and dynamic data with sufficiently accurate mathematical models which is to be implemented in high performance computing simulations. This is best accomplished within a Bayesian framework using Markov Chain Monte Carlo methodology. To achieve this goal, successful application of this proposal will enable a strong collaboration between applied mathematicians and a statistician to attack various problems in connection with the modeling of CO2 flow after injection and uncertainty quantification associated with it.
