Research Interests:

My principal research interest is carbon storage, one of the primary problems in the 21st century. In this context I study multi-phase fluid flow in sandstones and carbonates, which represent oil and gas reservoirs and aquifers - possible storage media. I also have high interest in the physical, chemical and fluid dynamical behaviour of supercritical carbon dioxide, especially in brine/rock and brine/hydrocarbon/rock systems.

The current question I am trying to answer is how supercritical CO2 spreads in the pore space of sandstones and carbonates; this wetting behaviour is a highly significant parameter determining capillary trapping, a carbon trapping mechanism recently identified as rapid and highly reliable (when making the assumption that CO2 is the non-wetting phase).

In order to tackle this question I developed a high pressure flow cell, which can operate at reservoir conditions, and which can be used in micro-computed tomography experimental setups - with which I can visualize the fluid distributions in the pore space of sandstones. The micro-CT results will be cross-compared with coreflood data acquired by Chris Pentland and then fed into network- and reservoir models by Prof. Martin Blunt. This work is part of the Shell Grand Challenge on Clean Fossil Fuels and will be extended to carbonates under the Qatar Carbonates and Carbon Storage Research Centre programme.

The wetting characteristic of scCO2 in such porous geologic systems is essentially a fluid-fluid-solid interaction phenomenon, which is strongly influenced by thermodynamic, geometric and physico-chemical effects. I have further interest in such interface science: liquid-liquid, solid-viscoelastic and foam-liquid interfaces are part of this, including surface chemistry, interfacial tension and mechanical response behaviour. Application areas in which I was involved and where these aspects are relevant include enhanced oil recovery, civil engineering (cladding systems) and chemical engineering (biodiesel production). Moreover, I am interested in computational fluid dynamics, molecular dynamics, molecular observations and percolation theory - future areas I will "dig" myself into in the future.
