Energy technology company SLB has been selected as strategic reservoir partner for the Havstjerne carbon storage project in the Norwegian North Sea, providing technology and engineering services for the concept and front-end engineering and design (FEED) phases, according to Splash247.
Project Overview
The Havstjerne project is a large-scale offshore carbon storage development in Norway intended to serve industrial emitters across Europe, according to Splash247. The project is operated by Harbour Energy in consortium with Stella Maris CCS. An appraisal well drilled in 2025 confirmed reservoir quality suitable for CO2 injection and storage, providing an important technical basis for the project’s continued development, Splash247 reported.
Funding and Technical Concept
The Havstjerne project received €225m from the EU Innovation Fund in 2025, Splash247 reported. The project has also selected a low-pressure floating storage and injection concept, which will serve as the basis for its technical design as it advances toward a final investment decision.
Scope of Work
SLB will coordinate an integrated project scope that connects underground storage reservoir analysis with injection well design, subsea infrastructure, and plans to monitor stored CO2, according to Splash247. The partnership will use this integrated approach to develop the project’s technical, cost, and schedule basis ahead of a final investment decision.
The concept and FEED studies will be delivered through close collaboration between SLB and its OneSubsea joint venture. The work is split as follows:
- SLB will provide the early engineering study, subsurface and reservoir maturation, and wells.
- SLB OneSubsea will deliver the concept and FEED for the subsea injection system, comprising the template manifold, all-electric trees, control system, umbilical, and distribution system.
| Scope element | Responsible entity |
|---|---|
| Early engineering study | SLB |
| Subsurface and reservoir maturation | SLB |
| Wells | SLB |
| Subsea injection system concept and FEED | SLB OneSubsea |
| Injection system components (template manifold, all-electric trees, control system, umbilical, distribution system) | SLB OneSubsea |
Project Management
"This integrated approach will help us further define the project’s technical, cost and schedule basis while strengthening coordination across critical interfaces," said Mark van Aerssen, Havstjerne project manager, as quoted by Splash247.
The selection of SLB as strategic reservoir partner marks a step forward for the Havstjerne project as it moves toward a final investment decision. With the appraisal well results confirming reservoir quality and the EU Innovation Fund providing financial backing, the project’s development will now progress through the concept and FEED phases, with SLB coordinating the integrated technical scope.
