Dr O’Sullivan has worked on a number of geothermal projects ranging from established fields to green field sites. He specialises in using numerical models to assist with strategic decision making and developing innovative modelling approaches to solve real-world problems. He is committed to the sustainable growth of global access to geothermal resources by helping to deliver successful projects through new research and by applying best practices in geothermal reservoir engineering and modelling.
Examples of his recent projects include:
- Uncertainty quantification using geothermal reservoir models (Bacman – Philippines)
- Risk mitigation for reinjection (Lihir – PNG)
- Subsidence modelling (Wairakei – NZ)
- Supercritical fluid modelling (Menengai – Kenya, TVZ – NZ)
- Environmental impact assessment (Rotorua – NZ)
- Resource assessment (Zunil – Guatemala)
He teaches on the Postgraduate Certificate course in Geothermal Energy Technology and supervises research projects for PhDs and Masters Degrees.
