Biography

I graduated from the University of Portsmouth in 2012 with a BEng Engineering Geology and Geotechnics. During the course, I worked as a placement student for a mining consultancy in Australia and a tunnelling contractor in Germany. After the degree, I stayed at the University and worked as a Laboratory Technician for a year before starting as a PhD student this year.

Research

My research interests are in the field of applied rock mechanics.  

Rock mechanics: Hydro-fracture in the laboratory and its use in linking permeable fracture networks to seismic data.

SUPERVISORS: Dr. Philip Benson (Portsmouth), Nick Koor (Portsmouth), and Dr. Mark Enfield (PDF Limited)

Hydrofracturing is a key process in many areas of pure and applied geosciences, such as the intentional hydraulic fracturing of impermeable rock formations in the hydrocarbon and geothermal energy industries. This project investigates the dependence and fracture mechanics behaviour of the fluid driven mechanical fracture process to assess the competition between permeability and overpressure upon the derived fracture pattern. In addition, new data is being generated to test the link between the measured seismicity and the accuracy of the fracture patters with the aim of calculating the permeability of the fracture network remotely, as well as using the seismicity as a forecasting tool to mitigate risk.
