My main research themes are:
A) Developing Carbon Abatement Technologies IN OIL INDUSTRY
Pore-scale imaging (both on micro-CT scanners and synchrotron sources at Diamond Light Source, Didcot, UK and Elettra, Trieste, Italy); modelling gas injection in multiphase flow in porous media; reactive transport in porous media; modelling and experimental studies of trapping of carbon-dioxide in porous media. Pore-scale direct simulation finite-volume based models (e.g. Bijeljic et al., Phys. Rev. E, 2013, Raeini et al., 2012) on micro-CT images and pore network models (e.g. Bijeljic et al., Phys. Rev. E, 2011; Blunt et al., Adv. Water Resour., 2013) are used to describe single and multiphase (gas/oil/water) flow in geologically representative porous rocks at the macroscopic scale.
The specific applications closely associated with this theme include CO2 storage in geological formations (aquifers and oil reservoirs) and enhanced oil recovery.
This work has been sponsored by Qatar Petroleum, Shell and Qatar Science and Technology Park, Pore-scale Modelling Consortium, Total, EPSRC, ETI and NERC. I am a member of and collaborating with the UK Carbon Capture and Storage Consortium, as well as QCCSRC and Shell Grand Challenge Programme on Clean Fossil Fuels and Energy Futures Lab at Imperial College.
B) Developing Modelling Tools for Contaminant Transport in Subsurface Hydrology AND PETROLEUM ENGINEERING
Preasymptotic and asymptotic liquid and gas dispersion in porous media; developed a novel methodology based on probability density functions of transit times between pores to fully describe solute dispersion. The outcome of this approach has been to unifiy pore-scale network modelling with Continuous Time Random Walks (CTRW) theory and experiment (Bijeljic et al., Water Resour. Res., 2004; Bijeljic and Blunt, Water Resour. Res., 2006). Relying on this concept, a physically-based explanation for anomalous transport processes in natural porous media has been provided at multiple scales (Rhodes et al. Adv. Water Resour., 2008).
Furthermore, a novel modelling approach based on direct simulation of flow and transport on the voxelised micro-CT images of natural porous media has resulted in a novel methodology to explain the origin of non-Fickian transport by looking into and relating probability density functions of velocity and displacement (Bijeljic et al., Phys. Rev. Lett., 2011; Bijeljic et al. Phys. Rev. E, 2013; Bijeljic et al., Water Resour. Res., 2013) - these can be routinely used for fast characterisation of porous media heterogeneity.
The specific applications include contaminant transport in aquifers and tracer and miscible displacement studies in oil and gas reservoirs.
C) Magnetic Resonance Imaging (MRI) Visualisation of flow in porous media
Coupled parallel fluid flow in heterogeneous porous media has been visualised by the non-invasive technique of MRI (Bijeljic et al., Phys. Fluids 2001; Bijeljic et al., Chem. Eng. Sci. 2004). This research has been conducted in collaboration with The Magnetic Resonance Researh Centre in the Department of Chemical Engineering at Cambridge University (Prof. Lynn Gladden). One of the most important boundary conditions in porous media, namely at the interface of free flow region and a porous structure has been shown to be greatly influenced by flow expansions/contractions in the free flow region. This has implications in the design of many industrial processes as well as in the description of flow in fractured porous media.
The specific applications closely associated with this research theme include mass transfer in packed beds, resin transfer moulding, heat and mass exchangers and filtration.
