Fluid dynamics and deformation of CO2 reservoirs
The geological storage of CO2 is a technological means of removing anthropogenic emissions from the atmosphere, and relies on stable long-term storage and sufficient subsurface pore space. As CO2 is injected into saline aquifers ambient brine is displaced, resulting in the flow of water and the deformation of the reservoir, as the pressure associated with injection migrates throughout the reservoir. In some cases effects of these pressure and deformation signals may be observed as small amplitude ground deformation.
We are seeking a postdoctoral researcher to work between the Department of Earth Sciences and the BP Institute to (i) develop a numerical model of pore-pressure diffusion in poroelastic groundwater aquifers, and (ii) to test this model against high-resolution satellite-based observations of surface motion using interferometric synthetic aperture radar (InSAR). The work builds on previous work within the group on the modelling of laterally extensive CO2 flows (at Sleipner), and on InSAR techniques applied in a host of settings.
Applicants should have experience in either fluid dynamics or InSAR imaging, and have demonstrated the capacity to perform independent research. Training will be provided in the required techniques that the successful candidate has not previously used. Previous experience in the mathematical and numerical modelling of flows in porous media and/or geophysical data analysis would be advantageous. The successful candidate must have PhD in a relevant field (e.g. Earth Sciences, physical sciences, engineering, mathematics or similar), a track record of publication in peer-reviewed international journals, and will have good communication skills in order to present results at international meetings.
Cambridge hosts active and multidisciplinary groups focused on geological carbon storage and space geodesy (including InSAR), with geochemical and multiphase flow work being carried out jointly between the Department of Applied Mathematics and Theoretical Physics, the BP Institute and the Department of Earth Sciences.
