MONITORING PROTOCOLS AND LIFE-CYCLE COSTS FOR GEOLOGIC STORAGE OF CARBON DIOXIDE

摘要

In this study two scenarios are used to evaluate the applicability of the monitoring techniques and the costs of deploying them over the life-cycle of a storage project. Key assumptions underlying the cost estimates such as reservoir size and depth are provided and major cost dependencies are described. For each scenario a "package" of suitable monitoring techniques is proposed with a commentary on how the components were selected. For each monitoring scenario a basic and enhanced monitoring program is evaluated. Estimated costs for monitoring geologic storage over the full life-cycle of a project at a range from $0.05 to $0.10 per tonne of CO_2 (discounted at 10%/year, undiscounted cost range from $0.16 to $0.31 per tonne). This paper summarizes one part of a study performed for the International Energy Agency Greenhouse Gas R&D Programme (IEA GHG) to provide an overview of monitoring techniques for geologic storage of CO_2.
