Summary
I am a PhD student investigating magnetic enhancements within hydrocarbon reservoirs, working with Professor Adrian Muxworthy, Professor Al Fraser and Professor Dominik Weiss.
My research focuses on the magnetic characteristics of oil-water interfaces at the base of sandstone and carbonate oil columns. Understanding the magnetic signature may help provide a new technique for calculating yield in mature reservoirs, thereby reducing the need for further exploration.
In addition, I have recently developed a new thermodynamic model to provide constraints on the conditions, i. e., pH, Eh, temperature, iron and sulphur concentrations, required to form and preserve the metastable iron sulphide, greigite (Fe3S4), in aqueous environments.
In 2017, I graduated from the University of Birmingham with a First Class (Hons) MSci degree, including a year studying at the University of Toronto. From 2017 to 2020, I worked for the geological consultancy, Cambridge Carbonates Ltd, where I produced geological maps and studied geophysical data through wireline logs.
