CCS geological storage

Secure, compliant and scalable geological storage for carbon capture projects Carbon capture, and storage (CCS) is central to reducing emissions while maintaining reliable energy supply and industrial output. The viability of any CCS development depends on one critical factor: if the subsurface can safely, efficiently and economically store CO₂ over the long term.
Place Summary Here
Organisations need to demonstrate proven storage capacity, robust engineering design, regulatory compliance and long-term monitoring strategies. These factors help shape investment confidence and determine project success.
We help clients navigate geological storage with a clear direction. Our team aids in delivering evidence, modelling and assurance to support investment decisions, secure permits and design reliable storage solutions.

How we can help you

Subsurface assessment

Our geoscientists and reservoir engineers assess formation suitability using seismic interpretation, well log analysis, core evaluation and dynamic reservoir modelling. This enables a clearer understanding of injectivity, containment integrity, plume behaviour and storage capacity.

Well engineering for safe CO₂ injection

We design and assess injection wells that comply with regulatory requirements, including US Class VI standards. Our work includes:

  • New CO₂ injection well design
  • Legacy well integrity assessment
  • Review of historical wellbore conditions and offset wells
  • Pressure, temperature and phase-behaviour modelling

These assessments reduce the risk of leakage, communication and operational issues.

Integrated surface and subsurface design

We facilitate alignment between storage formations and surface systems, integrating the following:

  • CO₂ capture, compression and dehydration facilities.
  • CO₂ transport and pipeline infrastructure.
  • Injection systems and plant design.
  • Monitoring for plume position, monitoring for micro-seismic events, measurement and verification systems.

Through this process, we can help your storage solution meet long-term injection and operational requirements.

Pre-operational testing and characterisation

We develop and implement testing programmes to confirm and refine storage characteristics, including:

  • Formation testing and core analysis.
  • Injection and confining zone characterisation.
  • Conducting baseline seismic, pressure and geochemical studies.
  • Integrity testing for new and legacy wells.

These programmes establish the technical foundation for long-term assurance.

 

Post-injection monitoring and closure

We design post-injection site care (PISC) and closure plans to support long-term containment and regulatory acceptance. Plans typically include:
 
  • Plugging and abandonment procedures.
  • Monitoring locations, methods and frequencies.
  • Predicted plume extent and pressure dissipation.
  • Reporting schedules and closure timeframes.
Regulatory compliance and permitting

We help clients meet regulatory requirements by preparing geological, engineering and environmental evidence for storage permits. These include:

  • Storage permit documentation.
  • Environmental assessments.
  • Risk and impact evaluations.
  • Regulatory submissions and compliance planning.

Our approach supports timely approvals and project credibility.

Commercial and economic considerations

We help clients understand the economic drivers of geological storage, including:

  • Incentive and taxation regimes.
  • Jurisdictional policy frameworks.
  • Cost and revenue modelling.
  • Investment-readiness for storage hubs

This supports effective budgeting, financing and commercial decision-making.

Delivering confidence in long-term storage
Geological storage is the foundation of any CCS programme. We bring together geoscience, engineering, environmental and commercial specialists to deliver resilient, integrated storage solutions. Having contributed to CCS hubs, regional storage appraisals and long-duration sequestration studies across multiple jurisdictions, our integrated team can provide the evidence needed to make informed, defensible decisions throughout the project lifecycle.
