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.

The large-scale offshore project, operated by Harbour Energy in partnership with Stella Maris CCS, a Yinson Production company, is designed to provide carbon storage capacity for industrial emitters across Europe.

SLB will coordinate an integrated scope covering reservoir analysis, injection well design, subsea infrastructure and CO2 monitoring.

The work will help establish the project’s technical, cost and schedule basis ahead of a final investment decision.

The company will handle early engineering, subsurface and reservoir development, and wells, while its OneSubsea joint venture will lead the concept and FEED for the subsea injection system.

This will include the template manifold, all-electric trees, control system, umbilical and distribution system.

SLB said the integrated approach could improve coordination across the carbon storage system while reducing technical and contractual interfaces.

An appraisal well drilled in 2025 confirmed reservoir quality suitable for CO2 injection and storage, supporting the project’s continued development.

Havstjerne received €225 million ($262 million) from the EU Innovation Fund in 2025 and has selected a low-pressure floating storage and injection concept designed to prioritise reliability, cost efficiency and commercial flexibility.

"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.”

"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.”

"The Havstjerne project demonstrates how collaboration across the value chain can help advance carbon storage solutions,” said Lars Gunnar Vogt, chief technical officer of Yinson Production. "We believe large-scale, cost-competitive CO2 storage infrastructure will play an important role in serving industrial emitters, and we look forward to continuing our collaboration with Harbour Energy and SLB.”  -OGN/TradeArabia News Service
