I have been involved in seismic research for over 15 years and have published on a diverse range of problems, spanning theoretical seismology, global seismology as well as hydrocarbon, carbon storage and engineering scale problems. My core expertise is in elastic and acoustic waveform simulation of seismic body-waves. I am involved in various energy studies related to modelling/monitoring geological storage of CO2 and nuclear waste, and conventional/unconventional hydrocarbon reservoir characterisation. This research is heavily multi-disciplinary, involving the integration of seismology, rock and petro physics, hydro-mechanics and geodesy.
Although the scientific community and many governments agree that greenhouse gases resulting from the use of hydrocarbon fuels are primarily responsible for producing damaging global climate change, society is still heavily dependent on hydrocarbon fuels for everything from electricity generation, transport, and manufacturing.
Geological storage forms an integral component of the carbon capture, transport and storage (CCS) engineering technology chain and is now recognised by most governments and scientists as a practical strategy with relatively immediate consequences in reducing global greenhouse gas emissions, continuing to meet the world's energy needs, and transitioning to low carbon economies. When CO2 is injected and stored in a geological formation, the in situ stress field is altered immediately due to increased pore pressure and reduced temperature within the reservoir. This leads to deformation in both the reservoir and surrounding rock. This deformation can change the injection and storage characteristics of the geological formation. Furthermore, substantial changes can significantly compromise cap-rock integrity (the barrier to upward flow of buoyant CO2) through the formation fractures and/or the reactivation of existing fractures or faults.
The objective of my fellowship is to address the fundamental uncertainty related to reservoir stress as a response to the geological storage of CO2. The fellowship aims to make a step change in quantifying the uncertainty and risks due to the injection and storage of CO2 in geological storage sites. The fellowship is an excellent opportunity to develop my expertise in geomechanics and, as such, push the relatively new field of Seismic Geomechanics to the next level.
