WINTERSHALL DEA ACHIEVES FIRST MILESTONE FOR CCS PROJECT GREENSAND
Project Greensand, which aims to store CO2 beneath the Danish North Sea, has cleared a first major hurdle. Injection and storage of CO2 in the Nini West subsea reservoir has been certified feasible by independent certification body DNV GL.
The Nini West oil reservoir is operated by INEOS Oil & Gas Denmark with Wintershall Dea as partner. With this certification DNV GL confirms that the reservoir is conceptually suitable for injecting 0.45 million tonnes CO2 per year per well for a 10-year period, and that the subsea reservoir can safely contain the CO2 in compressed form.
Wintershall Dea, INEOS Oil and Gas Denmark, Maersk Drilling and a research partner, the Geological Survey of Denmark and Greenland (GEUS) formed the Project Greensand consortium to reuse discontinued offshore oil fields for the permanent safe storage of CO2 captured at onshore industrial facilities.
Project Greensand targets having the first well ready for injection from the Nini platform in 2025. Longer term, the ambition is to develop capacity to store approximately 3.5 million tonnes CO2 per year before 2030.
Wintershall Dea brings to the project a strong knowledge of the relevant reservoirs and as Klaus Langemann, SVP for Technology & Innovation, explains, the company knows the environment well: “We have been producing from the relevant oil fields in Denmark for decades and already have a high level of knowledge of the reservoir characteristics. The Greensand Project will further advance Wintershall Dea’s understanding of CCS, so we are pleased to see this positive outcome, which states that there are no showstoppers for further investigating the storage of CO2. We are looking forward to further cooperation with the project partners for the next phase and are glad to contribute to a project with the potential to mitigate CO2 emissions in Denmark.“
The project forms a part of Wintershall Dea’s intention to support the
energy transition. Earlier in November, Wintershall Dea published greenhouse gas reduction targets, aiming for net zero for its production activities (scope 1 + 2 emissions, operated and non-operated upstream activities at equity share basis) by 2030. Beyond 2030, the company intends to significantly reduce Scope 3 emissions, which are mainly generated through the combustion of gas and oil it produces. Hydrogen and CCS can play a key role in this, as the company has both relevant assets and competencies to help in contributing to emission reductions.
