I work within the Department of Earth Sciences and study earthquakes triggered by fluid injection, and methods to mitigate induced seismicity. This has involved using a range of techniques from observational seismology, geomechanical modelling, and earthquake statistics to analyse microseismic datasets from injection operations around the world.My work has looked at fluid-fault interaction and the geologic controls of fault activation. My current research involves using seismological techniques to better quantify the state of stress and seismic hazard around developing and prospective CO2 reservoirs, leading to improved assessment of risks to longterm geologic CO2 storage for CCS operations. My work has lead to frequent interaction with industry and regulatory stakeholders.

My PhD in the School of Earth Sciences at the University of Bristol studied the mitigation and monitoring of injection-induced seismicity. I used large microseismic datasets to make geomechanical inferences, probing the physical mechanism behind fault reactivation, as well as the risk posed by injection near faults. My work initially focused on using elastostatic models to study the continued propagation of seismicity, in order to inform monitoring practises and regulation (traffic-light schemes). This has been combined with fault stability analysis, to determine the likelihood of failure for faults near the well. This work went on to be published in Geophysical Journal International in February 2019 (https://doi.org/10.1093/gji/ggz080). Further work on the triggering effect of opening hydraulic fractures was published in the Journal of Geophysical Research: Solid Earth in January 2020 (https://doi.org/10.1029/2019JB018794).Later work applied statistical methods to forecast maximum magnitudes of earthquakes induced during hydraulic fracturing in real-time, using the observed microseismic populations to determine the likelihood of larger, more hazardous events. Forecasts were generally successful, and were used to inform operational decision-making and enhance the utility of the monitoring programme. Results from this work were also published in Seismological Research Letters in September 2019 (https://doi.org/10.1785/0220190110).
