Geological Storage of CO2

Course Summary

This course provides participants with understanding of geological subsurface CO2 storage volumetrics, CO2 flow in the subsurface away from injector wells, the objective of permanent and safe storage of CO2. It also covers the key issues of reservoir depth, well design, reservoir lithology, reservoir quality, and reservoir architecture. Issues of mineral dissolution under different reservoir conditions are considered.
