Technical Program Themes

The Call for Abstracts is closed for 2026 CCUS and the full program will be posted in January 2026. Presentations will focus on the following themes:

Theme 01
CO₂ Capture

This theme encompasses recent developments in the capture of CO₂ from all sources, including fossil fuel-based power plants, ethanol production plants and industrial processes, as well as directly from the atmosphere. Capture providers need to consider optimizing an injectate stream to be compatible with subsurface conditions. Topics could include, but are not limited to:

  • Core CO₂ capture technologies, including point source capture and direct air capture (DAC)
  • Economics of CO₂ capture
  • Innovation and R&D in CO₂ capture
  • CO₂ injectate composition considerations for optimal subsurface storage
Theme 02
CO₂ Transportation

This theme encompasses recent developments in the transportation of CO₂. Topics could include, but are not limited to:

  • CO₂ pipeline design and construction
  • Repurposing existing infrastructure
  • Transportation monitoring
  • Other CO₂ transportation options (e.g. rail, ship, truck)
  • Multi-source and/or sink CO₂ networks and hubs
  • Integration of capture, transport and storage
Theme 03
Commercial and Regulatory Considerations

While addressing technical challenges with CCUS have been the mainstay of R&D over the years, near-term commercial deployment also hinges on the resolution of non-technical challenges such as legal access to pore space, UIC permitting, long-term liability, policy, and regulations, economic drivers, and economic tools, methods, and models. This session will address these issues in an ever-evolving landscape and sense of urgency with the development and deployment of CCUS technologies. Topics could include, but are not limited to:

  • Economics of CO₂ storage and financial risk
  • Best practices and lessons learned from UIC permitting process
  • Pore space ownership and land use considerations
  • Role of government support in advancing CCUS
Theme 04
Enhanced Oil Recovery and Other CO₂ Utilization

This theme aims to highlight the use of CO₂ for enhanced hydrocarbon recovery and associated storage. Topics could include, but are not limited to:

  • Optimizing CO₂ sweep efficiency for EOR/EGR projects
  • Geochemical insights from CO₂ injection in EOR/EGR fields
  • Monitoring, reporting, and verification of CO₂ in EOR/EGR fields
  • Studies on wellbore and facilities integrity for EOR/EGR projects
  • Regulatory and permitting insights for CO₂ EOR and utilization
  • Novel ideas to enhance storage during EOR/EGR
  • CO₂ utilization for industrial or commercial uses (e.g., synthetic fuels and feedstocks, building materials, or geothermal energy production systems)
Theme 05
Regional Characterization

Subsurface site screening describes the process of identifying potential CO₂ storage complexes and includes evaluating whether locations have critical storage elements: an adequate confining zone, adequate injection zone, and the absence of leakage pathways. Topics could include, but are not limited to:

  • Site screening methodologies
  • Evaluation of repurposing mature oil and gas fields for CO₂ storage
  • Regional assessments of pore space and CO₂ storage potential
  • Evaluation of non-conventional CO₂ storage
  • Using AI and machine learning for subsurface site screening
Theme 06
Site-focused Characterization

The site-focused characterization theme addresses key technical challenges in confirming whether a site is suitable for CO₂ storage: assessing Injection and Confining Zone properties, estimating storage resources and capacity, injectivity, and containment. Topics could include, but are not limited to:

  • Well coring, testing, and logging considerations
  • Methodologies to calculate storage resource and capacity
  • Geochemistry – Rock/brine/contaminant interaction
  • Confining Zone characterization
  • Subsurface risk management
  • Using AI and machine learning for subsurface characterization
  • Characterization of non-saline aquifers, e.g., in-situ mineralization of mafic/ultramafic rocks
Theme 07
Subsurface Modelling

This theme focuses on tools, workflows and outcomes of subsurface reservoir-scale modeling. Topics could include, but are not limited to:

  • Geologic or geocellular modelling
  • Dynamic simulation modelling
  • Geomechanical modelling
  • Reactive Transport modelling (i.e., coupled multiphase flow and geochemistry)
  • Using AI and machine learning for subsurface modeling
Theme 08
Well Design and Integrity

This theme also focuses on design and construction of wellbore materials. Topics could include, but are not limited to:

  • CO₂ Injection and monitoring wellbore design
  • Cement selection
  • Casing and tubing selection
  • Mechanical integrity testing
  • Evaluation of repurposing oil and gas wellbores for CO₂ storage projects
Theme 09
Testing and Monitoring

Subsurface testing and monitoring during the injection and post-injection phases is a key component of CO₂ storage projects. This theme welcomes submissions on new monitoring technologies, how to evaluate which technologies are fit-for-purpose for a particular site, and how to use these technologies to demonstrate conformance with flow modeling simulations. Topics could include, but are not limited to:

  • Seismic and non-seismic geophysical methods
  • Geochemical monitoring
  • Pressure and temperature monitoring
  • Integration of monitoring results to update simulation models
  • Machine Learning and AI techniques for testing and monitoring
  • Tools and techniques for leakage detection and quantification
  • Managing long-term containment and conformance risk
  • Economics and value proposition of testing and monitoring techniques
  • Real-time analytics and digital solutions
Theme 10
Operational Results

This theme includes real-world case studies of operational CCS and CCUS pilots and projects. Topics could include, but are not limited to:  

  • Demonstration/Pilot-scale test results
  • Large-scale tests and project results
  • Results from regional carbon initiatives
