CO2 Sequestration in Deep Saline Aquifers and Unminable Coal Seams

 

Dr. Kristian Jessen

Stanford University

 

Concerns about elevated concentrations of carbon dioxide (CO2) in the
atmosphere, resulting from accelerated consumption of fossil fuels, have
set off an effort to increase energy efficiency in general, and reduce
emissions from current anthropogenic sources. A workable option is to
capture CO2 from larger point sources, and inject it into geological
formations such as deep saline aquifers, unminable coalbeds, or mature
oil and gas reservoirs. During this talk, a mix of experimental,
analytical and numerical investigations of flow and transport phenomena
in candidate formations is used to demonstrate the sequestration
potentials.

Conventional simulation techniques are used to illustrate the modes by
which CO2 can get immobilized in aquifers and to delineate the time
scales for entrapment. A new approach, based on compositional streamline
simulation, is presented and shown to be far more efficient than
conventional simulation techniques for advection dominated flows.

Flow and transport of CO2/N2/CH4 mixtures in coalbeds is governed by a
complex interplay of advection, diffusion, and sorption. Analytical and
numerical solutions are presented and compared to experimental
observations to investigate our current predictive capabilities.
Sorption hysteresis is shown to play an important role for injection of
mixtures of CO2 and N2. 

Finally, the speaker will review the limitations of simulation tools
currently available for prediction of CO2 injection in the subsurface
and outline future research challenges.
