Geological Storage of Carbon dioxide
Abstract
This standard will describe the requirements and provide recommendations for storage of CO 2 in subsurface geologic formations along the lifecycle of a CCS-project to support safe and effective long- term containment of CO2. It will be based on the latest committee draft version of the updated ISO 27914 “Carbon dioxide capture, transportation and geological storage - Geological storage”. ISO 27914 represents an international standard which gives guideline on the aspects of geological storage of CO2. The available version of this standard has been published in 2017 and is currently undergoing an update process. The new version will take into account the technical developments of the last couple of years in this rapidly growing sector. Therefore, most recent version of the updated ISO 27914 (‘Committee Draft') is an ideal document which should be considered a basis for a respective European standard. The content of ISO 27914 shall be screened and adjustments shall be made where required to account for European needs around permanent storage of CO2. For example, one of potential topics to provide some guideline in the near future could be related to the impact of the increasing number of CO2 storage projects and their potential (pressure) interference, also cross -border. While CO2 storage in saline aquifers is prevalent, reusing depleted hydrocarbon fields for permanent stora ge of CO2, especially within the North Sea, is becoming of growing interest. The related challenges related to re - use of existing infrastructure from previous oil & gas activities could also be addressed in more detail in the European standard. The abovementioned topics shall be consi dered as suggestions (list is not exhaustive), while it is up to the working group to define the focus areas and level of detail of the standard. In any case, the European standard shall be clear and consistent in the use of definitions. In alignment with the latest committee draft of ISO27914, t he standard will provide guidelines on the following subjects: • Integrated Project Management (describing project phases and required plans) • Site screening, feasibility and characterization (including site assessment and modelling) • Risk management (describing criteria, plan, assessment, treatment and documentation) • Well infrastructure (incl. materials, design, construction, (re)completions and abandonment) • CO2 storage site operations (incl. design, plan, procedures, data acquisition etc.) • Measurement, monitoring and verification (incl. objectives, timing, methodologies etc.) • Project termination (describing criteria, plan, qualification process) It should be noted that this standard will cover the CO2 storage activities, from pre-injection site screening to project termination, explicitly including the measurement, monitoring and verification (“MMV”) for integrity of the storage complex. The primary objective of this working group is to produce precise, standardized technical guidelines and specifications that could be used to support the implementation of regulations, commercial contracts, and fiscal transactions and safety procedures in the realm of CCS. As ISO 27914, also this standard shall apply to injection of CO2 into subsurface geologic formations for the sole purpose of storage and does not apply to CO 2 injection for the purpose of enhanced hydrocarbon recovery, or storage of CO2 that occurs in association with it (CO2-EOR). The standard shall focus on monitoring, reporting, validating and verifying the CO2 for CCS-projects.
