This course will provide participants with awareness of the geoscience needs for CCS projects; namely subsurface CO2 storage volumetrics, CO2 flow in the subsurface away from injector wells, the goal of safe and permanent storage of CO2 and cost-benefit issues linked to aquifer depth, well design, etc. The course will establish basics, such as how much CCS is needed to make a difference to global warming, and explore what types of CO2 injection are already happening, including information from CO2-enhanced oil recovery projects. The course will deal with CO2 as a fluid phase and how much CO2 can be stored per cubic meter in terms of porosity and over entire aquifers. It will deal with how quickly CO2 can be injected and the role of aquifer permeability. The course then moves on to the all-important geomechanical effects of CO2 injection and feedbacks between induced mineral dissolution and rock strength and other rock properties. The full range of possible interaction between CO2 and both aquifer and top-seal will be covered, as will the range of possible leakage mechanisms that need to be assessed. The course will conclude with consideration of monitoring strategies.

Duration and Logistics

Five 3.5-hour interactive online sessions presented over five days (mornings in North America and afternoons in Europe). Digital course notes and exercise materials will be distributed to participants before the course. Some exercises may be completed by participants off-line.

Level and Audience

Advanced. The course is largely aimed at geoscientists, but engineers will also find the course instructive. Intended for sub-surface scientists, with an emphasis on geoscience topics. Participants will probably have a working knowledge of petroleum geoscience. However, the subject matter of this course, the geoscience of carbon capture and storage, is covered from basic principles.
