Offshore CCS at Draugen field

Background and purpose of the project?
Draugen is located in the southern part of the Norwegian Sea and started production in 1993. The field has been developed with a bottom-fixed concrete facility with integrated deck, and has both platform and seabed wells. Draugen has local power production using turbines. Together with the water injection pumps, which are also powered by turbines, these are the main source of CO₂ and NOx emissions to air.

It is a stated goal to reduce such emissions to air, both for the authorities and for the operator. The project is conducting a feasibility study where the goal is to demonstrate that it is technically feasible to capture and store CO₂ by integrating standardized CCS solution on an existing platform.

What was the goal of the project?
· To increase the maturity level of CO₂ capture facilities at offshore installations.
· Evaluate the integration of standardized solutions for CO₂ capture on a developed field that is in production. The work also aims to contribute to the development of more competitive, cost-effective and secure CO₂ management technology.
· Reduce environmental emissions to air.

What has the project done in terms of activities?
Two reports have been prepared under the auspices of the project. The first report describes how to extract CO₂ from the flue gas coming from the power turbines (Just Catch Offshore for Draugen Doc. No .: 103962-0000-ACC-Z-0001). The second report addresses the method of storing CO₂ in the Draugen field (Draugen Carbon Capture Storage Doc. No .: OKEA-DRG-SSU-REP-1014).

What has the project achieved? Were the goals of the project achieved?
The project has quantified how much you can reduce current CO₂ emissions by. A cost estimate has been made which gives an early indication of what such a project would cost. Risks have also been highlighted that may have an impact on whether the solution outlined is feasible.

Future plans?
As of today, it has been decided to put the work on pause. This decision has been made on the basis of the two reports referred to above. Should the work be restarted, the following activities have been identified as important in order to be able to document feasibility:

– Analysis of Draugen structure
– Study work from power turbine supplier
– Capacity study of existing cooling water system at Draugen.
