Global energy technology company SLB has been selected as the strategic reservoir partner for the Havstjerne carbon storage project in the Norwegian North Sea. The company will provide technology and engineering services during the concept and front-end engineering and design (FEED) phases of the large-scale offshore carbon storage development.
The Havstjerne project is being developed to provide offshore CO₂ storage capacity for industrial emitters across Europe. Harbour Energy is operating the project in partnership with Stella Maris CCS, a Yinson Production company. SLB will coordinate an integrated scope covering the underground storage reservoir, injection wells, subsea infrastructure and monitoring of stored CO₂. The work will help the project partnership establish the technical, cost and schedule basis required ahead of a final investment decision.
The scope includes concept and FEED studies involving SLB and its OneSubsea joint venture. SLB will undertake early engineering, subsurface and reservoir maturation activities and well design, while SLB OneSubsea will develop the concept and FEED for the subsea injection system.
The subsea system will include the template manifold, all-electric trees, control system, umbilical and distribution system. Combining these activities is expected to improve coordination between different parts of the storage system and reduce technical and contractual interfaces.
“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.”
An appraisal well drilled in 2025 confirmed reservoir quality suitable for CO₂ injection and storage, providing an important foundation for further development. The project also received €225 million from the European Union Innovation Fund in 2025. Havstjerne has selected a low-pressure floating storage and injection concept designed around reliability, cost efficiency and commercial flexibility. The approach is intended to support large-scale offshore CO₂ storage while providing a practical solution for 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 the importance of collaboration across the carbon storage value chain. He added that large-scale and competitive CO₂ storage infrastructure could play an important role in supporting industrial emitters.
The partnership brings together SLB’s reservoir, engineering and subsea capabilities with the project partners’ offshore development expertise. The work will support the next stage of Havstjerne’s development as it progresses toward a final investment decision.
SLB is a global technology company focused on the energy industry, providing technology, products and services that support oil and gas exploration and production, as well as the broader energy transition. Headquartered in Houston, Texas, SLB operates in more than 100 countries and combines expertise in reservoir characterization, drilling, production and digital technologies to help customers improve efficiency and performance. The company is also expanding its focus on lower-carbon energy solutions, including carbon capture and storage, geothermal energy, hydrogen and lithium production technologies.
