SCREENING
Our core expertise and the hardest part of our activities is to find and confirm where CO2 geological storage can be deployed. Our exploration is deployed across 3 pillars, which are fundamental to ensure sustainable CCS.
“Hard to abate” industry mapping
Finding out where industries which benefit from CCS are ready to deploy it on the long term
Geological suitability
mapping
Finding out where the geological setting allow for permanent and safe CO2 storage
Local acceptance
mapping
Finding out where local cities, neighbors, authorities and industries sees a value in deploying CCS
EXPLORATION
We start with surface exploration conducting detailed geological studies and seismic survey.
For the site who make the cut, we move forward with exploratory drilling to gather all data related to the geological formations which will take and hold the CO2 permanently. Extensive data acquisition is made and rigorous testing is conducted on the rock samples.
We explore by continuously focussing on the sequestration keys:
A proven robust sealing formation capable of structurally trapping CO2.
A permeable formation capable of accommodating the injection of CO2.

Balancing CO2 reduction with safe and permanent carbon capture and storage
CO2 SEQUESTRATION
The process involves injecting carbon dioxide into deep underground formations (>1000m), such as deep saline aquifers, depleted oil and gas reservoirs, or basalt formations. At these depths, CO2 exists in a liquid or supercritical state, making it very dense and taking up significantly less space than in the atmosphere.
For safe and permanent storage, geological storage takes place only in rock formations that are porous and permeable enough to allow CO2 injection. Once injected into the rock's pores, four different mechanisms ensure its permanent storage.
Structural trapping: A sealing rock prevents CO2 from moving upwards
Mineralization trapping: CO2 reacts with the rock, forming minerals.
Capillary trapping: CO2 becomes trapped within the small pores of the rock.
Dissolution trapping: CO2 dissolves in water, moving downwards.

STORAGE MONITORING
Ensuring the permanent containment of stored CO2 is the cornerstone of our mission. Without this assurance, all our efforts to reduce CO2 emissions would be rendered ineffective. Our CO2 storage surveillance is both comprehensive and customized to the specifics of each storage site, addressing all potential risks that might arise.
Storage complex monitoring & management is articulated across fundamental sphere or monitoring. For each, we deploy the best techniques and technology to continuously demonstrate the CO2 trapping, controlled location and integrity of the storage.
Geosphere - Protect rocks and uphold seal integrity.
Hydrosphere - Safeguard aquifers.
Biosphere - Protect flora and fauna.
Atmosphere - Prevent any CO2 surface leakage.
Well integrity - Ensure safe injection.
