Efficient numerical methods for deformable porous media. Application to carbon dioxide storage.
Over the last 150 years, the global temperature has risen at an accelerating pace. Human activity through emissions of greenhouse gases are considered the main cause of this relentless warming. Carbon dioxide (CO2) is one of the major greenhouse gases, which is most challenging to deal with, due to its prevalence as a by-product from industrial processes and electricity generation. To reduce greenhouse gas emissions into the atmosphere, CO2 capture and storage is considered as a highly relevant technology, and its study is therefore under active consideration. Due to their ubiquitous presence, deep saline aquifers provide the most substantial carbon dioxide storage capacity. The injection of CO2 into deep saline aquifers typically results in elevated pressure in the vicinity of the injection well. Due to the high injection pressure, the stress distribution in the reservoir region can change significantly, and therefore deformation of the porous medium must be considered to guarantee safety assessments of the injection process. This can result into uplift, fracture formation, and activation of existing faults. Therefore, there are potential risks to humans and ecosystems that arise from the leakage of CO2, or the displacement of saltwater from the saline to the fresh-water aquifers. The aim here is to advance in the applied mathematics techniques needed in this context. We will study modern numerical techniques and novel concepts, to be able to make a significant step forward in the numerical simulation of CO2 storage research. This involves detailed analysis to ensure accuracy of the numerical solutions, development of highly efficient multilevel solution methods for complicated governing nonlinear systems of partial differential equations (PDEs), but also uncertainty quantification (UQ) and the corresponding solution techniques.

Project objective
Continuum mechanics represents one of the most important research fields in applied sciences and engineering. Numerical simulation is increasingly prominent in this field, which forms the natural ground for application of very recent techniques of numerical analysis and scientific computing. In the last decades, the simulation of multiphysics problems, where different models interact to describe a complex phenomenon, has received a lot of interest. The current project is framed in this spirit, with the double aim of advancing in the numerical simulation techniques as well as in the improved understanding of the physics in the application field. As main line of work, we treat mathematical and practical aspects of models for nonlinear poroelasticity, with an emphasis on stable numerical discretizations and the use of fast solvers for the highly efficient solution of the resulting algebraic systems. Regarding the practical aspects, we focus on the simulation of the deformation of reservoirs during the carbon dioxide injection stage. In this innovative proposal, we also develop efficient methods for uncertainty quantification in order to assess the risks involved in such process and to evaluate the impact on the environment. The cooperation between Professors Francisco Gaspar and Cornelis Oosterlee goes back 20 years, when they met (as young and fresh) researchers in FhG SCAI in Germany, and cooperated very successfully on multigrid methods. Then, both researchers went their own way (one in Spain, the other in the Netherlands). Now, both being almost 50 years of age, it is important to cooperate closely again, at Oosterlee’s host institution in the Netherlands. Prof. Gaspar is willing to come over to Amsterdam for two years, to boost the research and open new research directions, such as uncertainty quantification.
