“…Dentz and Tartakovsky 2008) or semi-analytical solutions (e.g. Saripalli and McGrail 2002;Nordbotten et al 2005) based on certain simplifications have been proposed. Several of these simplified approaches have already been adapted in system assessments or monitoring plans by various research groups (e.g.…”

The Geomechanics of CO2 Storage in Deep Sedimentary Formations

2012

This paper provides a review of the geomechanics and modeling of geomechanics associated with geologic carbon storage (GCS), focusing on storage in deep sedimentary formations, in particular saline aquifers. The paper first introduces the concept of storage in deep sedimentary formations, the geomechanical processes and issues related with such an operation, and the relevant geomechanical modeling tools. This is followed by a more detailed review of geomechanical aspects, including reservoir stressstrain and microseismicity, well integrity, caprock sealing performance, and the potential for fault reactivation and notable (felt) seismic events. Geomechanical observations at current GCS field deploy-

“…These have been the subject of recent numerical (Pruess et al 2003;Doughty and Pruess 2004) and analytical (Saripalli and McGrail 2002;Riaz et al 2006;Nordbotten and Celia 2006) studies. The attraction of numerical solutions lies in their versatility and ability to handle complex geochemical processes and various geologic settings.…”

Abrupt-Interface Solution for Carbon Dioxide Injection into Porous Media

We derive an approximate analytical solution, which describes the interface dynamics during the injection of supercritical carbon dioxide into homogeneous geologic media that are fully saturated with a host fluid. The host fluid can be either heavier (e.g., brine) or lighter (e.g., methane) than the injected carbon dioxide. Our solution relies on the Dupuit approximation and explicitly accounts for the buoyancy effects. The general approach is applicable to a variety of phenomena involving variable-density flows in porous media. In three dimensions under radial symmetry, the solution describes carbon dioxide injection; its two-dimensional counterpart can be used to model seawater intrusion into coastal aquifers. We conclude by comparing our solutions with existing analytical alternatives.
