AGR delivers an independent resource assessment for two CO₂ storage licences on the Norwegian Continental Shelf

Carbon Capture and Storage (CCS) has become a vital solution as momentum grows in the global effort to reach net-zero emissions. The Norwegian Continental Shelf (NCS) offers significant potential for permanent geological storage of CO₂, but identifying and verifying viable sites requires technical precision and independent evaluation.

We were engaged to perform an independent assessment of the storage potential of two CO_₂ storage licences on the NCS. The evaluations were carried out under the SPE Storage Resources Management System (SRMS) — the industry standard for consistent classification and reporting of CO₂ storage resources.

Project description: Evaluation and screening of two carbon storage licenses
Location: EXL005 Poseidon license (covering blocks 10/7, 10/8, and 10/9) and EXL011 license awarded to Aker BP in 2024 (covering blocks 25/3, 26/1, 26/2, 30/12, 31/10, and 31/11) showcasing our deep expertise in CCS and geological CO_₂ storage assessment
Duration: H2/2024

The Challenge

The Operator of the two licences needed to evaluate them side-by-side on a neutral and consistent basis. This meant determining:

• The maturation level of each licence
• Evaluate and quantify storage resources
• The CO_₂ plume mobility in the reservoir over time, and
• The risk of leakage into overlying formations or nearby wells — all of which could influence the classification and overall feasibility of each site.

To meet regulatory standards and secure future development support, the Operator required an independent third-party CCS consultant to carry out a robust technical review and quantify the CO_₂ storable quantities.

How our subsurface team made a difference

As an independent consultant, we provided a structured and comprehensive evaluation that included:

• Quantifying the CO_₂ storable quantities of each licence using SRMS reporting standards
• Assessing reservoir performance and plume migration over time, based on available subsurface data and simulation scenarios
• Evaluating potential leakage paths, including geological faults, wellbore integrity, and overburden sealing capability — all key factors affecting containment security
• We applied our CCS knowledge and understanding of storage classification frameworks to deliver a fit-for-purpose, technically sound assessment tailored to the project’s strategic needs.

Why CO₂ Storage Resources Management System (SRMS) matters

The SPE CO₂ Storage Resources Management System (SRMS) provides a globally recognised method for defining, classifying, and reporting CO₂ geological storage resources. By adopting this standard, we helped the Operator ensure transparency, comparability, and compliance with international best practices — a critical step in attracting investment and enabling regulatory alignment.
