1.     Why are you involved in geothermal/supercritical research?

I've always thoroughly enjoyed geothermal research as it allows me to solve challenging/diverse/multi-scale problems and creates opportunities for multi-skills development.

I have a long-standing interest in the numerical simulation of complex mass and heat flow phenomena, as well as chemical processes, in highly heterogeneous porous media.

GNG supercritical geothermal research project is a fantastic opportunity for me to apply my knowledge and pursue my research on a grander scale for:

• an improved understanding of the deep structure and dynamics of the geothermal systems
• a greater understanding of the physical and chemical natures of the deep fluids, their flow pathways, and interactions to be encountered during production and reinjection.

2.     What is the favourite part of your work?

The numerical reservoir modelling studies I conducted provide predictions on sustainable utilisation of geothermal resources and contribute to the optimum design of waste fluid reinjection strategies. My favourite part of my work at the GNG project is the research on the reinjection of NCG (non-condensable gases) into geothermal reservoirs, aiming to reduce greenhouse gas emissions and enable low-carbon energy generation from geothermal systems.I also take joy in supervising students because supervision allows me to share the enthusiasm of inspired geothermalists.

3.     Please share the publication you're most proud of

Kaya, E., O'Sullivan, M.J., Hochstein, M.P.(2014), A Three Dimensional Numerical Model of the Waiotapu, Waikite and Reporoa Geothermal Areas, New Zealand, Journal of Volcanology and GeothermalResearch , 283, 127–142.

What was the research finding?

We investigated the underground movement of hot and cold flows to elucidate the region's gross permeability structures, the location of upflows, and the hydrological connection between Waiotapu, Waikite, and Reporoa geothermal areas.

Why is it important?

• Supporting utilisation of Māori-led geothermal opportunities
• Sustainable management of the fields
• More effective guardianship of important cultural and spiritual values
