Dr. Katherine Duncker Romanak

Google Scholar profile

Since 2007, Dr. Katherine Romanak has been a lead geochemist who has developed environmental monitoring plans for over 6 actively injecting, large-scale CO2 storage projects. Katherine is an academic that works alongside industry to develop, innovate, and apply CO2 storage technology in real-world applications. Katherine pioneered a process-based soil gas monitoring approach, which avoids costly and complex baseline data collection and initiated the paradigm shift of near-surface monitoring. Katherine’s CO2 monitoring method has become a standard approach to environmental monitoring worldwide. She has championed the concept of leakage “attribution” as a critical part of monitoring in the near surface.

Katherine was an independent technical lead assessing the first-ever claim of CO2 leakage by a landowner living on the Kerr Farm near a CO2 injection site. Using attribution techniques, Katherine and her team determined that no leakage had occurred at the Kerr Farm, and the experience outlines the importance of having protocols for responding to stakeholder concerns in place before a project begins.

Katherine is often the scientist-in-the-room providing technical information into global regulations at the UNFCCC COPs and in the USA (Class VI and California Low Carbon Fuel Standard CCS protocol), which has led to an improvement of responsibly injecting CO2 and their regulations that protect both the environment and carbon storage projects. Katherine serves on many international advisory panels, and technical boards, and continues to effectively convey monitoring and environmental safety for geological CO2 storage to wide stakeholder audiences. Katherine provides professional training for subsurface oil and gas professionals who want to repurpose their skills for CCS. Katherine is the co-instructor who helped develop the new online CCS certification program at The University of Texas at Austin.

Principal Research Accomplishments & Impacts

Tomakomai Offshore CCS Demonstration Project, Hokkaido Japan (2017–2016)  Environmental monitoring at Japan’s first full-chain CCS project, the Tomakomai CCS Demonstration Project led by Japan CCS Co. Ltd to implement and demonstrate CCUS projects in Japan, and to investigate associated technologies through international collaboration.

Hastings and West Ranch CO2-EOR sites, Texas USA (2016–2011)  Near-surface monitoring design and implementation at the largest (< 1.5MMT/year) U.S. commercial CCS projects (Petra Nova and Air Products), representing the first commercial applications of monitoring techniques developed and tested at the Cranfield site.

Cranfield Project, Mississippi USA (2015–2009)   Near-surface monitoring design and implementation at the first project in the US DOE Regional Carbon Sequestration Partnership portfolio to reach 1 million metric tons (MMT) of storage, finally reaching 5 MMT.

CTSCo Environmental Baseline Works, Queensland, Australia (2018–2015)   Soil-gas monitoring design and implementation to demonstrate the technical viability, integration and safe operation of CCS in the Surat Basin during the feasibility study stage, and to undergo assessments and approvals in environmental, social and technical aspects under relevant government regulation.

Kerr Farm Allegation of Leakage at the Weyburn-Midale CO2 storage site Saskatchewan, Canada (2013–2011)   Led a team to respond to the first-ever claim of leakage at a CO2 storage site which provided valuable experience in how to approach public engagement and environmental monitoring.
