Abstract

How microbes affect gas energy extraction/storage depends on the complex interactions among the hydraulic-mechanical-chemical-biological processes. In this study, these coupled processes are defined as “geo-multiphysics”. The goal of this research is to advance the understanding on geo-multiphysics during gas energy extraction/storage in subsurface formations with a focus on the role of microbial activities. To achieve this goal, a generic geo-multiphysics model for gas energy extraction/storage is developed. Then, the generic geo-multiphysics model is tailored to two cases. One is the case of biogenic methane extraction from coal seams and the other is the case of underground hydrogen storage in aquifers.
