The Project Greensand consortium, consisting of INEOS Oil & Gas Denmark, Wintershall Dea and Maersk Drilling, has been issued a certification of feasibility by DNV GL for the storage of CO2 at the Nine West reservoir in the Danish North Dea.
Projects about carbon storage, capture carbon dioxide emissions and stores them in coal seams, aquifers, depleted oil and gas reservoirs and other spaces deep under the surface of the Earth.
Specifically, DNV GL’s Carbon Capture and Storage certification is the first step for the Project Greensand project aiming to develop capacity to deliver a significant part of Denmark’s CO2 reduction target by reusing discontinued offshore oil fields.
Project Greensand aims having the first well ready for injection from the Nini platform in 2025, and the consortium is aiming to develop the capacity to store around 3.5m tonnes CO2 per year before 2030.
The Nini West field has been deemed suitable for injecting 0.45m tonnes CO2 per year per well for a 10-year period, with the subsea reservoir able to safely contain the CO2 in compressed form.
Marika Reis, Head of Innovation at Maersk Drilling commented that
As part of the next phase of validation, we will be applying DNV GL’s certification scopes for suitability of the CO2 injection well design and well construction process. We’re excited to be able to bring our competencies to use in this effort to deliver significant emission reductions.
