Geochemistry of CCS: Reservoirs, Seals and the Engineered Environment
Format and Duration:
2 days
4 sessions
The geochemistry of saline aquifers, depleted oil/gas fields in the context of CO2, and other waste gas, injection is considered. The reactions of CO2 with different reservoir rocks and top-seals, and their constituent minerals, and the cement and metal work used in the construction of wells are central to this course. The course includes reference to numerous CCS and CO2-EOR case studies, CCS-pilot sites, experiments, geochemical modelling, reaction-transport modelling, monitoring of CCS sites, microbiological processes in CCS systems, and the risk of halite scale formation.
Schedule
Duration and Training Method
This is a classroom or virtual classroom course comprising a mixture of lectures, discussions, and case studies. Exercises will include hand calculations, largely based on spreadsheets. This course includes e-learning elements that provide background content on Carbon Capture and Storage that serves to provide an introduction to the subject matter:
- EC003 Fundamentals of CCS
- EC004 Geological Storage of CO2
- EC005 Behaviour of CO2 in Reservoirs
Course Overview
Learning Outcomes
Participants will learn to:
- Establish the types and sources of information needed to define geochemical aspects of CCS sites.
- Examine the role of water and mineral composition, CO2 pressure, and composition of the injected gas in influencing reactions at CCS sites.
- Evaluate how experimental simulation can help define if mineral dissolution or precipitation will occur in CCS systems.
- Summarise CO2 interactions with cements and pipes used in well completions.
- Appraise how geochemical reaction modelling can help define what processes will occur over a range of timescales at CCS sites.
- Assess the application of reaction transport modelling to simulation of CO2 flow and reaction over a range of timescales at CCS sites.
- Correlate geochemical processes to geomechanical and petrophysical properties in CCS systems.
- Use geochemical tracers to track process in CCS systems.

Richard Worden
Background
Professor Richard Worden is leader of the Diagenesis Research Group and programme director of the MSc on Petroleum Reservoir Geoscience at Liverpool University. He has more than 30 years of industry and research experience.
Prof. Worden undertook a BSc in Geology and Geochemistry at the University of Manchester, completing it with a 1st class honours degree in 1984. Following a PhD at Manchester University in 1988, he worked for BP Research and BP Exploration in Sunbury, UK, for 6 years. This was followed by a lectureship at Queen’s University in Belfast until 2000 and then a professorship at Liverpool University.
Richard has worked on a number of areas of research, almost all related to oil and gas geoscience, with focus on high quality reservoir-scale data (including quantitative mineral and textural data, and the integration of petrophysical, petrographic, geomechanical, geochemical, and sedimentological data) to help with oil and gas exploration, appraisal and asset management. He has worked extensively on sandstone reservoir quality throughout his career, with focus on the causes of anomalous porosity-preservation in deeply buried sandstone reservoirs. His research is now extending into reservoir property-related issues involved in the energy transition (CCS, hydrogen generation and storage). He has published seminal papers on the role of microquartz coatings and on the effects of early oil emplacement on quartz cementation, with a key paper on chlorite-inhibition of quartz currently in press with the Bulletin of the American Association of Petroleum Geologists.
