Geological Sequestration of Carbon Dioxide: A Viable Option for Mitigating the Greenhouse Effect

byProfessor Dongxiao ZhangMewbourne School of Petroleum and Geological EngineeringThe University of OklahomaAbstractA dramatic increase in anthropogenic Greenhouse Gas (GHG) emissions since the
Industrial Revolution is thought to be responsible for current global warming trends.
Carbon dioxide comprises more than half of all atmospheric GHG emissions, resulting
primarily from combustion of fossil fuels. Carbon management is a broad national
and international policy response to address these climate change issues.
Sequestration is the most direct carbon management strategy for long-term removal
of CO2 from the atmosphere, and is likely to be needed for continuation of the US
fossil fuel-based economy and high standard of living. National and international
investments in research on carbon sequestration are ramping up rapidly. At the same
time, carbon sequestration is becoming a new branch of science and engineering.
During this seminar, I will address R&D issues and opportunities associated with
geological carbon sequestration as well as some of our recent research activities in
this area. In particular, a recent pilot study of sequestrating CO2 in a depleted oil
reservoir as well as results for some key issues associated with geological carbon
sequestration (e.g., viscous fingering and wormhole formation) will be discussed in
detail.Thursday, April 19, 2007
