Research interests

 

My research aims to optimise geothermal energy production. As a production geologist, I model the geology of aquifers to quantify recoverable heat and geological uncertainties. I use detailed geological models in production simulations to understand the impact of geological heterogeneities on subsurface flow and heat exploitation. The results form the basis of evaluation of optimal well placement strategies, required policy and legislation. To generate geological models, I use a range of geological subsurface data such as well logs, seismic surveys, cores, as well as drill cuttings. My work is related to different types of geothermal resources such as Hot Sedimentary Aquifers and Enhanced Geothermal Systems.

 

Bibliography

I joined the School of Engineering as a Postdoctoral Research Assistant in January 2018, as part of the horizon2020 DESTRESS project (www.destress-h2020.eu). Prior to this, I took seven months to travel through the Amazon and South America with a 300 Tdi Land Rover Defender. From January to May 2017, I worked as Postdoctoral Researcher in the Geothermal Engineering group at the Technical University Delft where I also received my PhD, a BSc in Chemical Engineering and an MSc in Petroleum Engineering.
