SLB (NYSE: 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 a company statement.

The project is operated by Harbour Energy in consortium with Stella Maris CCS, a Yinson Production company. Havstjerne is designed to store CO2 from industrial emitters across Europe and received €225 million from the EU Innovation Fund in 2025.

SLB will coordinate an integrated scope connecting subsurface reservoir analysis with injection well design, subsea infrastructure and CO2 monitoring plans. The work will be carried out ahead of a final investment decision. SLB's OneSubsea joint venture will deliver the concept and FEED of the subsea injection system, which includes a template manifold, all-electric trees, a control system, umbilical and distribution system.

An appraisal well drilled in 2025 confirmed reservoir quality suitable for CO2 injection and storage. The project has selected a low-pressure floating storage and injection concept.

"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.

Mark van Aerssen, Havstjerne project manager, said the integrated approach will help define the project's technical, cost and schedule basis while strengthening coordination across critical interfaces.
