Geological CO₂ storage
Did you miss our talk for Eliis at the Tech Forum during the first week of December 2024? Here, our colleagues George Jones and Sidsel Lindsø presented the technical subsurface work that we have been responsible for, on behalf of Altera Infrastructure who is partner with 40% ownership in the EXL 006 Havstjerne CO2 storage license. Due to an approval process they had a Plan B ready, just in case: it was a presentation demonstrating how we have used the PaleoScan software in another area, and an area close to the Frigg Field that was recently open for CO2 license applications and will soon be awarded.
We thought it could be valuable for you to learn how it is possible to visualise reservoirs and sealing shales deep in the ground. Therefore, we have decided to share the ‘Plan B’ with you. It is still our Intellectual Property and you cannot use it without our permission, but you can use it for inspiration and learning. The examples below are from the presentation.

Over the past 4-5 years, we have built up a diverse portfolio of projects, totaling more than 20 ventures. Here are some of our accomplishments so far:
Facilitated successful CO₂ storage license applications, resulting in awards for our clients.
Conducted CO₂ storage screening projects for multiple clients, helping them identify viable opportunities.
Currently serving as the subsurface team for a partner in a CO₂ storage license, covering crucial responsibilities mandated by authorities.
Independently evaluated and documented all potential onshore and nearshore Danish sites for CO₂ storage.
Provided subsurface advisory services to several European NGOs and CCS networks.
Developed innovative tools, such as our proprietary Proxy Model Reservoir Simulation Tool. Check out its advantages

With detailed insights into the CO₂ storage capacity of several European CCS countries, we offer commercial evaluation and independent audits of potential storage sites.
Geological mapping and identification of CO₂ storage.
We assist clients in building CCS business cases with detailed studies of CO₂ storage capacity. Our existing database consists of interpreted seismic data correlated to quality assured well information. Together with technical subsurface expertise, we can deliver a database of ranked opportunities in specific areas of interest.
To speed up the process we have invented two different tools that enable us to predict and model CO₂ storage injection capacity and CO₂ storage capacity in the dynamic domain in a very time efficient manner and at a low cost.

Over the last few years, we have built significant competence within the science of storing CO2 safely and with good confidence that the CO2 will stay safely underground.
COMPETENCE & CAPABILITY: The competence needed by geologists, geophysicists, and reservoir engineers for evaluating storage capacity is very much the same as for evaluating oil and gas prospects, when it comes to geoscience. This is especially true for making sure that the seals are of high quality and that there are no potential leakage points that could cause leakage of the stored CO2 when the reservoir is pressured up.
However, when it comes to how the CO2 behaves when being injected into deep reservoirs and how it affects the surroundings, it is completely different. That is why the reservoir engineering aspect of CO2 storage capacity and knowing the aquifer extent is so important.
EXPERT ADVICE: Fortunately, we have one of the best experts within the field as our Associated Specialist, and Lex Rijkels has even developed a proxy model for most CO2 storage reservoirs. Using this, we can provide an initial view on the suitability of a potential storage site, estimate how many injection wells that are needed and the magnitude of CO2 that can be injected per year. This is fundamental information required for building business cases.

To understand more about the detailed technical work we carry out to understand the risks associated with geological CO₂ storage, the independent evaluation of potential CO₂ storage sites in Denmark is a good example.
In the autumn 2023 our team went in depth to understand the details of the CO2 storage capacity of Denmark. The background is that the national CO₂ storage atlases are based on high-level assumptions that needs to be investigated in further detail, as a natural step in the maturation process for CCS projects.
In the independent evaluation the CO₂ storage capacity of 18 sites onshore and nearshore in Denmark was evaluated. A total of 45 stratigraphic intervals observed in wells were evaluated. This comprises a reservoir unit combined with a seal unit to ensure the CO₂ is stored safely underground. Out of the 45 intervals evaluated only 15 of these were considered a quality that would be relevant for further maturation. Note that some of these 15 intervals form stacked targets at sites.
Our conclusion is that only selected potential CO₂ storage sites has the potential capacity to be further matured. This also means that both authorities, investors and others getting involved in the CO₂ storage business need to be fully informed and have performed due diligence processes on the subsurface risks before committing to any investment decisions.
