Carbon capture and storage solutions

Offshore carbon capture and storage (CCS) solutions that support wells, platform projects, long-term CO2 management, decarbonisation and repurposing

Supporting the offshore carbon capture and storage economy

The energy transition is placing hydrogen centre-stage, and carbon capture and storage (CCS) is critical for a successful blue hydrogen supply chain (and for other carbon-generating industries).

There are several ways to approach offshore carbon capture and storage projects. From mature and depleted reservoirs, to brand new storage locations – what’s common is that there are a number of critical engineering considerations and competencies required in successfully storing CO2 in subsurface formations.

At Aquaterra Energy we’re ready with the expertise and equipment to support you with the most efficient approach to your offshore carbon capture and storage project. To learn more about CCS developments and platform repurposing, read our exciting press release detailing our contract with INEOS.

Well projects for CO2 and CCS Storage 

Our portfolio of equipment and intelligently engineered solutions already helps oil and gas operators globally accelerate time to first oil, reduce rig time and drive cost efficiencies for well intervention and workover projects. ​This knowledge and expertise can also be applied to offshore carbon capture and storage projects too. 

Our work across riser systems, riser analysis and efficient well initiation is underpinned by our deep engineering expertise – ensuring that whatever solution we design, develop, and install meets the needs of each client and each application.​ 

We offer a range of integrated system packages and enhanced engineering strategies to bolster offshore carbon capture and storage operations, save rig time and accelerate the storage of CO2. 

Well abandonment for CO2 integrity

Key to carbon storage is the integrity of the formation/reservoir that the CO2 will be stored within. ​Whilst legacy oil and gas fields are considered good carbon storage locations, given the proven formation properties and existing pipeline and platform infrastructure, a key risk and liability is the remaining suspended, or abandoned legacy wells.  

These legacy wells may have been abandoned correctly at the end of the field’s life, but barrier selection and testing may reveal that a reservoir might not be suitable for underground CO2 storage applications. ​A field that would otherwise be the perfect carbon storage location could be discounted due to CO2 integrity concerns, or even need a costly relief or intersection well drilled to correctly plug and abandon the legacy well and ensure its secure.  ​ 

At Aquaterra Energy our field-proven well re-entry  and tieback engineering products and services can help carbon capture and storage projects eliminate issues and realise their potential.

We can help you with:

  • Detailed reviews of current well abandonments, e.g. for safety case submission​ 
  • Worst case planning – such as a well intersection plan ​ 
  • Base case planning – re-entry into well via tieback, plus contingency options ​ 
  • Riser analysis, equipment supply, interface engineering, 3rd party management, plus offshore services   ​ 

Offshore platforms for CO2 injection 

If you’re looking at using a platform to re-inject CO2 into an offshore storage location, you may be presented with the choice of using an existing platform that is already in a suitable location or designing and installing a new platform.  

Our unrivalled life of field and brownfield modification experience means we’re perfectly placed to support in upgrading existing infrastructure to store CO2 in depleted reserves. From compressor considerations to wellheads and pipe engineering, our team of platform engineers can support with all platform simplification and modification requirements. 

If your project requires a new platform installation, our Sea Swift offshore platform for CCS developments is the ideal shallow water solution. Its modular design minimises build and implementation times, reduces capex and overall project emissions. Sea Swift can be adapted for a range of field development requirements, supporting anything from one well, up to 10 wells. 

We can offer a complete EPCI project solution from conductor and riser analysis through to design, fabrication, project management and offshore installation. ​Learn more about one of our most recent injection projects.

Long term CO2 Management 

CO2 leak detection and response planning are an essential element in the development and long-term storage of any project, reducing environmental risk and providing reassurance of asset integrity. 

We’ve developed a complete CO2 monitoring platform solution for offshore carbon capture and storage projects that uses field-proven CSS technology to provide you with the confidence that your storage sites are performing as expected, against baseline engineering and seismic data, during and post CO2 injection.  

This, combined with our patent pending approach to long-term site integrity, will provide a further measure of security by alerting engineers to any actual CO2 leaks into the water column long during and after the injection process has been completed.
