Anomalous Transport in Geological Media: non-Fickian dispersion models and inversion


Project Description

Anomalous Transport in Geological Media: non-Fickian dispersion models and inversion

Supervised by Dr Matteo Icardi (Maths), Dr. Bagus Muljadi (Engineering), Dr. Marco Bianchi (BGS)

This project will be based at the University of Nottingham in the School of
Mathematical Sciences, in collaboration with the GeoEnergy Research Centre, the School of Engineering, and with the British Geological Survey.

Predicting solute transport in complex geological media is essential for addressing key environmental challenges, such as the groundwater remediation, and has an important role in geological exploration for evaluating risks of water contamination in carbon sequestration, nuclear waste storage, landfill dumps, unconventional hydrocarbons. However, such predictions are often unreliable due to the heterogeneity of the subsurface, the sparsity of direct observations, and the number of physical and chemical factors acting over multiple spatial and temporal scales. In recent years, upscaled transport models have been proposed able to reproduce non-standard phenomena such as early-time solute arrivals, asymmetric plumes, and persisting low-concentrations at late-times. However, the calibration of these upscaled transport models is based on extensive fitting with relatively large amount of data.

The main objective of this project is to develop a quantitative approach for predicting solute transport in complex geological media, through a combination of fully resolved fluid dynamics simulations, multiscale mathematical analysis of PDEs and SDEs, and data assimilation. Realistic geological heterogeneities will be considered, enabling reliable risk assessments and model inversion for reducing uncertainties. This project is connected to the EU-H2020 funded grant SECURe and will see the collaboration of several international and UK partners.
