- One of the approaches suggested for sequestering CO₂ is by injecting it in coalbed methane (CBM) reservoirs. Despite its potential importance for CO₂ sequestration, to our knowledge, CO₂ injection in CBM reservoirs for the purpose of sequestration has not been widely studied. Furthermore, a key element missing in most of the existing studies is the comprehensive characterization of the CBM reservoir structure. CBM reservoirs are complex porous media, since in addition to their primary pore structure, generated during coal formation, they also contain a variety of fractures, which may potentially play a key role in CO₂ sequestration, as they generally provide high permeability flow paths for both CO₂ and CH₄. In this report we present an overview of our ongoing experimental and modeling efforts, which aim to investigate the injection, adsorption and sequestration of CO₂ in CBM reservoirs, the enhanced CH₄ production that results, as well as the main factors that affect the overall operation. We describe the various experimental techniques that we utilize, and discuss their range of application and the value of the data generated. We conclude with a brief overview of our modeling efforts aiming to close the knowledge gap and fill the need in this area.
