Format and Duration:
20 hours
This package of Carbon Capture and Storage (CCS) self-paced e-learning courses will provide geoscientists and engineers with an awareness and understanding of subsurface CO2 storage, CO2 flow in the subsurface, and monitoring of the CO2 storage site. It addresses the key issues of reservoir depth, well design, reservoir lithology, and quality.
EC003 - Fundamentals of Carbon Capture and Storage (CCS) provides participants with awareness and understanding of the subsurface needs of CCS projects. It will establish basics such as how much CCS is needed to make a difference to global warming and explore what types of CO2 injection have already happened including dedicated long-term CCS projects, pilot projects and CO2-enhanced oil recovery projects.
EC004 - Geological Storage of CO2 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.
EC005 - Behaviour of CO2 in Reservoirs addresses CO2 as a fluid phase and the key question of CO2 storage efficiency, the equivalent of oil recovery factor. The course will address the rate of CO2 injection and the role reservoir permeability. The all-important issue of the geomechanical effects of CO2 injection and feedbacks between induced mineral dissolution and rock strength and other rock properties will be addressed. The range of possible interaction between CO2 and both aquifer and top-seal will be covered.
EC006 - Monitoring CO2 Storage considers the range of potential leakage mechanisms that need to be assessed. It will include a detailed consideration of the monitoring strategies available to assure the safety and integrity of the CO2 storage site.
Training Method
This is a bundle of self-paced e-learning courses. Learning materials are structured into short sections, each including interactive text and image content, animations, video, and audio. End of course quizzes are scored to provide the learner with their learning progress.
