How do you deliver the missing link in a CCS value chain?

Challenge

A client came to us with a nearly complete CCS business value chain. The missing piece? A suitable CO₂ storage site in Norway – south of the Northern Lights Aurora license and as close to mainland Europe as possible.

With commercial deadlines approaching, time was critical. The challenge was to quickly identify, screen and mature a viable site that could support long-term storage and align with the client’s strategy.

Approach

We activated our subsurface team and tapped into our regional database to accelerate screening. Using the PaleoScan software by Eliis, we built high-resolutions seismic models to evaluate geological storage potential across a wide area. The criteria were clear: reservoir depth beyond 800 meters, robust sealing shale, and alignment with the client’s commercial strategy.

Based on this, we delivered a ranked inventory of potential CO₂ storage sites. One stood out – and was selected and matured. We created a dynamic model, created scenarios for injectivity, and proposed an optimised well plan. An expected potential storage capacity range was a result from the studies.

Are you a non-subsurface expert working with getting access to CO₂ storage space? Get in touch: we can run by your side and make sure things are done right.

Result

The selected site was successfully applied for and awarded as EXL006 Havstjerne. Stella Maris CCS chose to continue working with our subsurface team in their role as license partner.

Since then, we’ve supported the maturation of the site and worked closely with the operator on planning an appraisal well with injection testing. 

The potential CO₂ storage site was tested with well 9/6-1 in spring 2025.
