The course 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.
Courses are accessed on the RPS Learning Hub, each course consists of a series of modules of up to 90 minutes learning time, including self-assessment elements. Learning materials are structured into short sections, each including interactive text and image content, animations, video and audio. An end of course quiz is scored to provide the learner with their learning progress.
