Potential for CO2 storage in depleted fields on the Dutch Continental Shelf–Cost estimate for offshore facilities

AbstractA study was performed on capital and operational costs for offshore injection of CO2 into depleted fields. The main focus was on the design and costs of process requirements for injection, required conservation (hibernation) and modification of existing platforms between end of gas/oil production and start of CO2 injection. Also cost estimates for new platforms are provided.The study is ‘high level’ and generic in nature as no specific target for CO2 storage has been selected. For the purpose of this study a simplified approach is used for determination of the required injection facilities and platform modifications. Nevertheless, the study provides a good indication on the level of expenditures that can be expected
