Geological Storage of CO2: a State-Of-The-Art of Injection Processes and Technologies

摘要: An overview is given of the well technology needed for CO2 injection and near wellbore processes: - Well materials abandonment procedures must be designed in order to avoid leakage through ensure long-term safety storage. Furthermore, various mechanical effects can affect process. Geomechanical models are required identify optimal pressure that will damage neither nor reservoir. The region subjected chemical phenomena due which may drastically injectivity. These dissolution/reprecipitation mechanisms very case-dependant need more theoretical experimental investigation control injectivity a well, crucial because huge amounts have injected.
