| Abstract |
Recent papers confirm that the capacity and injectivity of CO2 stores may, in certain circumstances, be substantially enhanced by the removal of brine as the formation is pressurised by CO2 injection. Brine production as a means of controlling well pressure is well understood and currently practised as part of the oil industry. As the United Kingdom is currently screening potential stores, it is important to quantify how much enhancement to CO2 storage might be available, and at what cost. This project’s goal is therefore to investigate brine production and the opportunities it may offer stores of different type and inform the UK’s principal screening tool - the CO2 Stored database licensed by the British Geological Survey/The Crown Estate.
The work will involve geological modelling and cost estimations for offshore equipment and activity.
The Project will be split into two stages, with reports and presentations to the ETI at the end of each stage. |
