SLB Selected as Strategic Reservoir Partner for the Havstjerne Carbon Storage Project
SLB has been selected as strategic reservoir partner for the Havstjerne carbon storage project in the Norwegian North Sea, providing technology and engineering services during the concept and front-end engineering and design (FEED) phases of the large-scale offshore development.
The Havstjerne project, operated by Harbour Energy in consortium with Stella Maris CCS, a Yinson Production company, is being developed to provide offshore CO₂ storage for industrial emitters across Europe.
Under the agreement, SLB will coordinate an integrated project scope connecting analysis of the underground storage reservoir with injection well design, subsea infrastructure and monitoring plans for stored CO₂. The work is intended to help the Havstjerne partnership establish the project’s technical, cost and schedule basis ahead of a final investment decision.
“Carbon storage projects are moving from individual technical studies toward integrated development models that connect the subsurface, wells and offshore infrastructure,” said Gavin Rennick, president of SLB’s New Energy and Industrial business. “Havstjerne demonstrates how SLB can bring together its technology, engineering and project integration capabilities to help customers develop the technical basis needed to advance large-scale carbon storage projects.”
SLB will provide early engineering studies, subsurface and reservoir maturation and wells, while SLB OneSubsea will deliver the concept and FEED for the subsea injection system. This will comprise the template manifold, all-electric trees, control system, umbilical and distribution system.
The integrated approach is designed to improve technical coordination across the storage system while reducing the number of technical and contractual interfaces as the project moves toward investment decisions.
An appraisal well drilled in 2025 confirmed reservoir quality suitable for CO₂ injection and storage, providing an important technical foundation for the continued development of Havstjerne. The project also received €225 million from the EU Innovation Fund in 2025.
Havstjerne has selected a low-pressure floating storage and injection concept focused on system reliability, low cost and commercial flexibility. The concept is intended to support the development of a large-scale offshore CO₂ storage facility capable of serving European industrial customers.
“Havstjerne is being matured to provide a cost-effective, large-scale offshore CO₂ storage for European industrial emitters,” said Mark van Aerssen, Havstjerne project manager. “This integrated approach will help us further define the project’s technical, cost and schedule basis while strengthening coordination across critical interfaces.”
Lars Gunnar Vogt, chief technical officer of Yinson Production, said the project demonstrates how collaboration across the carbon storage value chain can help advance large-scale CO₂ storage solutions.
The latest agreement brings together SLB’s subsurface, wells and engineering capabilities with SLB OneSubsea’s subsea expertise as the Havstjerne partnership works to mature the project toward a final investment decision.
