Major efforts on CCS in carbonate reservoirs

Five PhD students have been appointed to investigate CO2 Sequestration in Carbonate reservoirs 

The greatest scientific and technological challenge of this century is how to provide energy to a growing global population, while avoiding dangerous climate change. The storage of CO2 in deep subsurface geologic reservoirs is broadly recognized as an essential first step to mitigate greenhouse gas emissions, including assessments made by the Intergovernmental Panel on Climate Change, the Commission on European Communities, and the United States Department of Energy. Safe Carbon Capture and Storage requires a good understanding of the geology of the formations of interest, both for the reservoir rocks and the cap-rock. The carbonate group at Imperial College has worked three years on the topic of CCS in carbonate rocks, and is planning a renewed major effort on this topic with 5 new PhD students to begin in October 2012:

Project 1: Extent and formation of diagenetic dolomite bodies
Two PhD students have been appointed and will be responsible for studying the geometry, structural context, diagenesis and geochemistry of fracture-related dolomite bodies. More detailed information on this project available here.

Project 2: Investigating sedimentologic heterogeneities in carbonate reservoirs
One PhD student was appointed on this topic, and will study the geometry and depositional processes of carbonate sediments (reservoir) outcropping in regions considered to be analogous to subsurface reservoirs. More detailed information on this project available here.

Project 3: Sedimentologic heterogeneities and diagenesis of anhydrite seals
Onw PhD student will constrain at the outcrop the sedimentologic and diagenetic heterogeneities present in anhydrite caprocks. More detailed information on this project available here.

Project 4: Fracture potential of anhydrite caprocks and history of paleofluid flow
One PhD student will work on reconstructing the fracture and fluid flow history of anhydrite cap-rocks. More detailed information on this project available here.
