- Non-Conventional Storage Reservoirs
Theme 2: Subsurface Modeling
Description: This theme focuses on topics related to subsurface modeling (hydrological, geomechanical, geochemical, thermal) studies for CO2 storage to understand fate and transport of CO2 as it relates to storage capacity, trapping, injectivity, and containment. Topics could include, but are not limited to:
- Analytical Models
- Dynamic Multiphase Flow Simulations (including coupled flow and thermal modeling)
- Geomechanical Models and Simulations
- Pore-Scale Modeling
- Reactive Transport Modeling (i.e., coupled multiphase flow and geochemistry)
- Data Assimilation (i.e., incorporating laboratory data, monitoring data, and/or historical data into numerical models)
Theme 3: Subsurface Risk Assessment
Description: This theme aims to address recent advances in the field of subsurface risk assessment, workflows, and mitigation strategies associated with injection and storage and/or utilization of CO2. Topics could include, but are not limited to:
- Risk Assessment Workflows

Theme 4: Infrastructure and Well Design
Description: This theme intends to explore recent advances and learnings in developing fully integrated CCS projects that include interfacing between capture, transport, and storage sub-systems. This theme also focuses on design elements of surface, and subsurface infrastructure, including wells, that consider regulatory requirements, project needs, and supply chain considerations. Topics could include, but are not limited to:
- CCS Hubs – Different CO2 Composition Streams – Reservoir Compatibility
- Emerging Technologies for CO2 Injection and Monitoring Wells
- Innovative Well Designs for CO2 Injection and Monitoring
- Corrosion Resistant Alloy Well Construction-Cost to Benefit
- Well Coring, Testing, and Logging Considerations
- Operations and Data Management
- Drilling and Cementing Lessons Learned
- Repurposing Existing Wells-Methods and Case Studies
Theme 5: EOR, Injection, and Utilization
Description: The EOR, Injection, and Utilization theme aims to highlight the use of CO2 for enhanced hydrocarbon recovery and associated storage in both conventional and unconventional reservoirs, focusing on the learnings from operators on injecting and monitoring enhanced oil/gas recovery (EOR/EGR) projects. In addition, we are eager to hear about utilization of CO2 for other purposes such as feedstock for sustainable aviation fuels, cement manufacturing, and other technologies. Topics could include, but are not limited to:
- CO2 injection modeling studies in fields or labs
- 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
- Co-optimization of EOR/EGR and storage
- Economic evaluations of CO2 EOR/EGR projects and for transitioning fields from “EOR Business as Usual” Class II to Class VI permanent storage
- Regulatory and permitting insights for CO2 EOR and Utilization
- Utilization of CO2 for non-EOR applications: synthetic fuels, energy storage, power generation, and other technologies
- Surface and Subsurface mineralization technologies for carbon storage
- Novel ideas to enhance storage during EOR/EGR (foam, formate, tight/shale among others)
- Direct sequestration vs. utilization – which makes sense based on policies and economics
Theme 6: Subsurface Monitoring
Description: Subsurface monitoring of injected CO2 is required by regulators in the U.S. and other countries to confirm that the injected CO2 stays where it is put. Monitoring is also important for determining the location of the pressure plumes because such plumes can elevate the risk for faulting, seismicity, and reservoir containment issues as well as affect injectivities at other regional injection operations. Lastly, monitoring is required by some regulators to validate that claimed CO2 injection volumes have been permanently stored to unlock earned financial incentives. This theme welcomes submissions on 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:
- Low-Cost Monitoring
- Integrated Monitoring
- Emerging Technologies
- Monitoring Plan Optimization
Theme 7: Financial, Economics, and Regulatory Framework
Description: While 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:
- Project Financial Risk
- Best Practices and Lessons Learned from Current CO2 Storage Permitted Projects
- Regulatory Risk
- Risk of Meeting GHG Mitigation Targets
- Class VI Permitting and Standards
- 45Q, LCFS and Carbon Markets
