Numerical stratigraphic modelling of lithological heterogeneities

Project Overview

Full project title: Numerical stratigraphic modelling of lithological heterogeneities: geological reservoir characterisation for carbon capture and underground storage 

The project, funded by Geosolutions Leeds, is part of the University of Leeds' exciting new strategic investment as outlined in its Climate Plan. It supports the refocusing of research and training to achieve Net Zero goals and accelerate the Energy Transition.

The project aims to deepen our understanding of deep saline aquifers and their potential for underground CO2 storage, which is crucial for achieving net-zero emissions.

Deep saline aquifers can hold more CO2 and keep it stable at depths greater than 3,000 meters, compared to injecting CO2 into old oil and gas reservoirs, making them a more suitable option for underground CO2 storage. However, these aquifers have varied rock layers that need to be understood to predict how the CO2 will behave.  

Therefore, the project will develop new tools to model these complex subsurface reservoirs, using the largest database of sedimentary structures to guide the models. The advanced modelling software will also be utilised to: 

• Predict the 3D geometry and structure of different rock layers.  
• Predict the distribution and connectivity of different types of rock layers within a subsurface reservoir.  
• Model how CO2 will flow through these reservoirs.  
• Evaluate the potential of Carbon Capture, Utilisation, and Storage (CCUS) in targeted Permo-Triassic successions.  

The project will assess the potential and prospect ranking of selected subsurface reservoirs for CO2 storage and help make informed decisions.
