Monitoring and Modelling Injection Induced Seismicity

I am currently a third year PhD student in the School of Earth Sciences at the University of Bristol studying the physical mechanisms behind injection-induced seismicity and fault reactivation. I use techniques employed in observational seismology, geomechanical modelling, reservoir geomechanics, and statistics to analyse large microseismic datasets from hydraulic fracturing operations around the world.

Much of my work has focused on using elastostatic models to study the continued propagation of seismicity, in order to inform monitoring practises and regulation (e.g. "traffic-light" schemes). This has been combined with fault stability analysis, to determine the likelihood of failure for faults near injection. This work has now been published in Geophysical Journal International. My recent work has been investigating the application of statistical methods to forecast maximum magnitudes in real-time, using the observed microseismic populations to determine the likelihood of larger, more hazardous events.
