Geophysical Research for Gigatonnes CO2 Storage

Part 1: Geophysics from Research to Solutions: Status, Gaps, Challenges

Part 2: Geophysical Recommendations for Regulators and Operators


14–19 July 2024
Colorado School of Mines
Golden, Colorado, USA

The SEG Research Committee CO2 Sub-Committee is happy to announce the Geophysical Research for Gigatonnes CO2 Storage workshop scheduled for 14–19 July 2024 at the Colorado School of Mines in Golden, Colorado, USA.


This SEG and Geologic Carbon Storage (GCS) summer research workshop is dedicated to advancing geophysics in the context of GCS. It emphasizes interdisciplinary research and best practices with a focus on site characterization and monitoring, site integrity, and risks related to injectivity, and seals and faults. The workshop’s distinctive format encourages networking and open discussions, aiming to cultivate a dynamic knowledge nexus for the secure geological storage of CO2 consistent with governmental regulations and guidelines, and international best practices. With two key segments, the workshop will assess the current status, gaps, and challenges in geophysics for GCS and provide recommendations for regulators and operators, positioning itself as a vital platform for geophysical advancements in GCS. The workshop will also provide an environment to discuss new energy topics such as the geophysical aspects of geothermal and hydrogen.


Geologic Carbon Storage (GCS) represents a critical component of global efforts to mitigate carbon dioxide (CO2) emissions and combat climate change. The secure geological storage of CO2 requires a multidisciplinary approach, with geophysics playing a central role in monitoring and ensuring the integrity of GCS sites. The SEG GCS workshop emerges in response to the growing demand for in-depth exploration of geophysical techniques and their application in GCS as well as other new energy topics and projects.

Workshop Overview

Part 1: Geophysics from Research to Solutions: Status, Gaps, Challenges

In this segment of the workshop, attendees will engage in a deep dive into the current state of geophysics in the context of GCS. It will include:

  • Status Assessment: An overview of the current status of geophysical methods and technologies in GCS projects, highlighting successes and areas for improvement
  • Identifying Gaps: Discussion of the gaps and limitations in geophysical approaches, with an emphasis on what needs further research and development
  • Challenges and Innovations: Exploration of the challenges encountered in applying geophysics to GCS, as well as innovative solutions and emerging technologies
  • Interdisciplinary Insights: Cross-disciplinary discussions on how geophysics can collaborate with other fields to address complex GCS challenges effectively

Part 2: Geophysical Recommendations for Regulators and Operators

This section will focus on providing concrete recommendations and insights for both regulatory bodies and GCS operators, including:

  • Regulatory Framework: Discussion of the role of regulators in ensuring the safety and effectiveness of geophysical monitoring in GCS projects, with an emphasis on aligning with international regulatory guidelines
  • Operator Perspectives: Insights into the practical considerations and experiences of CCS operators when implementing geophysical site characterization and monitoring solutions
  • Best Practices: Presentation of best practices and case studies showcasing successful geophysical approaches in GCS
  • Adaptive Methods: Highlighting the adaptive nature of geophysical methods and their ability to evolve to meet changing GCS requirements and standards

Overall, the SEG GCS summer research workshop aspires to foster collaboration, knowledge sharing, and the development of a dynamic body of knowledge that will contribute significantly to the secure geological storage of CO2 and make the workshop a cornerstone of geophysical advancements in the realm of GCS.

Call for Abstracts

We are pleased to invite you to submit abstracts for the Geophysical Research for Gigatonnes CO2 Storage Workshop, organized by the SEG Research Committee – CO2 Sub-Committee, and the SEG Passive Seismic Committee. This workshop is dedicated to advancing the field of geophysics within the context of Geologic Carbon Storage (GCS), representing a critical component of global efforts to mitigate CO2 emissions and combat climate change.

Part 1: Geophysics from Research to Solutions: Status, Gaps, Challenges

Part 1 of the workshop will emphasize interdisciplinary research and best practices, focusing on site characterization and monitoring, site integrity, and risks related to injectivity, seals, and faults. After three decades of active research on Geologic Carbon Storage, the industry is now headed to creating multiple storage hubs across the world. Such hubs will require next generation monitoring and verification systems to ensure security and permanence of the storage. CO2 storage will need to rapidly grow in scale and require geophysical tools to facilitate the growth. Our aim is to create a dynamic knowledge nexus that aligns with governmental regulations, international best practices, and the secure geological storage of CO2.

We welcome abstracts on the following topics:

  • Geophysical Site Characterization for Geological Storage: Saline aquifers, basalt formations, depleted and producing oil & gas reservoirs – comparisons and distinctions from oil & gas reservoir characterization
  • Cost-effective long-term monitoring of subsurface CO2 storage by geophysical imaging: Quantitative estimates of in-situ CO2 volumes, leak detection
  • Geologic Carbon Storage and measurable parameters
  • Quality Assurance and Quality Control of data required for Measurement Monitoring and Verification (MMV)
  • CO2 storage and geomechanics: Induced seismicity, seal and wellbore integrity, monitoring pressure fronts
  • Geophysical signatures of the presence of CO2 and associated physical-chemical effects
  • Applications of artificial intelligence and machine learning to CO2 storage – Sites identification, characterization, and monitoring
  • Role of numerical simulation: Closing the loop between geophysical monitoring and modeling of coupled fluid flow-geomechanics phenomena
  • New geophysical and geochemical sensors for long-term monitoring
  • Opportunities for applied geophysicists in large-scale CCS and challenges in educating and training the necessary geoscience workforce
  • Regional issues: Case studies, regulations, interactions between large-scale sequestration projects
  • New Energies in the realm of mitigating carbon dioxide emissions
  • Social license to operate

Part 2: Geophysical Recommendations for Regulators and Operators

Part 2 of the workshop will provide a set of recommendations from the SEG for geophysical methods to be used with geological CO2 sequestration, for the benefit of regulators and operators. While it is not feasible to produce a useful set of recommendations in two days at a workshop, we will develop a framework for a set of recommendations to be produced, as well as a plan and a timely schedule.

We welcome abstracts on the following topics:

  • Cost versus benefit of geophysical methods for CO2 sequestration:
    • Overview of the most important geophysical methods for geological CO2 sequestration, with geophysicists and non-geophysicists perspective
    • Provide a realistic overview of the costs and the benefits of that method
    • Single specific topic, such as passive seismic monitoring, or 4D VSP, or reflection seismic, or other is encouraged
  • Review of current projects and practice:
    • Overview of geophysical methods that are currently being used or developed by operators or service companies for geological CO2 sequestration, with geophysicists and non-geophysicists perspective
    • Include the sequestration site that is in use or will be used, as well as a summary of the geophysical methods that are in use or will be used
  • Regulator’s perspective on geophysical methods for CO2 sequestration
    • Regulators to describe the geophysical methods that they would like to have available for geological CO2 sequestration
    • Intended to provide alignment between the methods that regulators really want and the groups who are developing methods, or improving methods, or reducing the costs of methods
