| Popis: | Estimating the capacity of a geological formation to store CO2 is not a straightforward or simple process. Bradshaw [1] has recently listed various estimations for both regional and global CO2 storage capacity. The estimations were quoted as "very large" with ranges for the estimates in the order of 100 s to 10,000 s Gt of CO2. Clearly this work shows the lack of definitions, rules and general practices in calculating CO2 storage potential. In earlier studies TNO has strongly emphasised the need for a more uniform and standard method to calculate the storage potential of any subsurface location, either a partial or empty hydrocarbon field or aquifer. TNO prefers to consider in any storage capacity calculation the inclusion of a concept of total affect space, i.e. all space that has its state or qualities changed by the storage operation over the total storage time. Furthermore, we will have to consider the injectivity of the selected injection location and the pressure and fluid conductivity of the total affected storage space. In addition, the intended free CO2 storage location will need to have enough storage space or enough sealing capacity to contain the CO2 for at least 10,000 years and prevent it from migrating to the surface. TNO has developed a method (van der Meer, [4]) which has been used for calculating of the maximum storage volume in the Netherlands. The method is based on the affected space and maximum pressurisation. The storage potential is further based on injectivity and finally the storage efficiency of the geological trap. The results of this work are compared with previous estimations. © 2009 Elsevier Ltd. All rights reserved. |
