Trusted GEOMECHANICS
Risk mitigation is first and foremost with carbon capture and sequestration. Aquitaine Energy Ltd. provides comprehensive geomechanics to assess cap rock integrity, risk of induced seismicity from CO₂ injection, fault reactivation and in-situ stress changes.
The world’s energy landscape is evolving, with the safe removal of CO₂ becoming a key strategy in the quest to achieve a net zero future. CCS has been in practice for nearly five decades, with rapid global growth in the last 15 years. Safe, subsurface storage of CO₂ is most often utilized within saline aquifers and depleted oil and gas reservoirs. Aquitaine Energy Ltd. bridges the gap between geoscience and engineering, providing comprehensive subsurface integration and modeling for existing and potential CCS storage.
saline aquifers &
depleted reservoirs
Storing CO₂ in saline aquifers is beneficial due to their large capacity, proximity to emission sources, and geological security for long-term containment.
CO₂ injection in Saline Aquifers
This method minimizes land use impact, offers potential for enhanced oil recovery, and poses lower risks to drinking water. Advanced characterization and monitoring ensures both safety and compliance.

CO₂ injection in Depleted reservoirs
Storing CO₂ in depleted reservoirs offers notable advantages, such as the use of proven geological structures and existing infrastructure, which can significantly reduce costs and uncertainties.

These reservoirs are well-characterized from previous oil and gas operations, facilitating more efficient CO₂ storage planning and enhanced oil recovery opportunities. The established cap rocks in these reservoirs minimize leakage risks, while existing monitoring technologies aid in effective CO₂ management. Additionally, utilizing depleted reservoirs typically faces fewer regulatory and public acceptance challenges and has a lower environmental impact due to the reuse of existing sites, making it a more sustainable option for CO₂ storage.
