Abstract of the Lecture: Carbon capture and sequestration (CCS) is the only currently available technology that can significantly reduce atmospheric carbon emissions while allowing continued use of fossil fuels for electric power and industrialproduction. CCS involves capturing the CO2 before it is emitted to the atmosphere, and injecting it into deep subsurface formations, thereby keeping it out of the atmosphere for centuries to millennia or longer. While conventional, high-permeabilityformations have traditionally been considered as injection targets, recent proposals suggest possible injection of captured CO2  into unconventional reservoirs with low permeability, specifically  depleted  shale-gas  reservoirs.     Analysis  of  injection  into both  types  of formations  involves computational challenges, in part because of the need for comprehensive environmental risk assessments and associated analysis of possible leakage scenarios. A range of computational models can be developed toanswer the most important practical questions associated with both of these injection options. In this presentation, different modeling approaches will be discussed and important practical questions related to injection of CO2 into both conventional and unconventional formations will be addressed.

About  the  Speaker: Professor Michael  Celia  is  the  Theodora  Shelton  Pitney  Professor  of  Civil  and Environmental Engineering at Princeton University, where he served as Department Chair for the CEE Department from 2005 to 2011. He is currentlyDirector of the Program in Environmental Engineering and Water Resources. Prof. Celia received a B.S. in Civil Engineering from Lafayette College in 1978, an M.S. in Civil Engineering from Princeton University in 1979, and a PhD from Princeton in 1983. In1985 he joined the faculty of M.I.T., and returned to Princeton to join the Civil Engineering faculty in 1989. Professor Celia's areas of research include groundwater hydrology, multi-phase flow in porous media, numerical modeling, and subsurface energysystems with a focus on geological sequestration of carbon dioxide and shale-gas systems. Ongoing projects include development of new simulation tools to model CO2 injection, migration, and possible leakage associated with carbon capture and geologicalsequestration (CCS); studies of multi-phase flow and transport in porous media with a focus on multi-scale models, including pore-scale models; and measurements and modeling for shale-gas systems with a focus on methane leakage, possible CO2 injection intodepleted shale-gas reservoirs, and the fate of fracking fluids. The CCS work is part of a large industry-funded multi-disciplinary effort at Princeton known as the Carbon Mitigation Initiative. Professor Celia served for 10 years as editor of the journal Advances in WaterResources. He is a Fellow of the American Geophysical Union (AGU) and the American Association for the Advancement of Science (AAAS) and the recipient of the 2005 AGU Hydrologic Sciences Award (citation: For fundamental research contributions tosubsurface hydrology and numerical methods in water resources, and for providing a model of Academia at its best). He was the 2008 Darcy Lecturer for the National Ground Water Association (title of the lecture: Geological Storage as a Carbon MitigationOption; the lecture was given at 52 different venues in 12 countries across North America, Europe, Asia, and Australia). He was also the 2010 Pioneers in Groundwater lecturer for the American Society of Civil Engineers, received the 2012 Hydrology DaysAward, and is the most recent (2014) recipient of the Honorary Membership Award from the International Society for Porous Media (Interpore). As a contributing author for the IPCC Working Group III Special Report on Carbon Dioxide Capture and Storage, Professor Celia shares, with many colleagues, the 2007 Nobel Peace Prize.
