Harbour Energy selects partner for Havstjerne carbon storage project
Harbour Energy Norge AS has selected SLB Ltd. as strategic reservoir partner for the Havstjerne carbon storage project in the Norwegian North Sea.
SLB will coordinate an integrated project scope that connects analysis of the underground storage reservoir with injection well design, subsea infrastructure, and plans for monitoring stored carbon dioxide (CO2) as the Havstjerne partnership develops the project’s technical, cost, and schedule basis ahead of a final investment decision.
The scope includes concept and front-end engineering and design (FEED) studies delivered through close collaboration between SLB and its OneSubsea joint venture. SLB will provide an early engineering study, subsurface and reservoir maturation, and wells, while SLB OneSubsea will deliver the concept and FEED of the subsea injection system, comprising the template manifold, all-electric trees, control system, umbilical, and distribution system.
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. The Havstjerne project—which received €225 million from the EU Innovation Fund in 2025—has selected a low-pressure floating storage and injection concept focused on system reliability, low cost, and commercial flexibility.
Havstjerne is a large-scale offshore carbon storage development in Norway intended to serve industrial emitters across Europe, operated by Harbour Energy (60%) in consortium with Stella Maris CCS.
