Biography

I am a Postgraduate Researcher (PGR) based in the School of Earth & Environment at the University of Leeds, looking into the structural constraints on volcanic geothermal systems in Iceland. I previously completed my Integrated Masters in Applied Geology at the Indian Institute of Technology (IIT) Kharagpur in 2020. After graduating, I spent the next 3 years working as an Exploration Geologist at Cairn Oil & Gas in India. I commenced my doctoral studies at the University of Leeds in October 2023.

Project outline

Structures such as fractures and faults play an important role as fluid flow pathways in geothermal reservoirs located in active tectonic regions. A proper understanding of fracture distribution, how they act as either pathways or barriers to fluid flow and their response to dynamic stress changes is often essential for reservoir development. My doctoral research aims to investigate the extent and impact of structural constraints on fluids and heat flow in the volcanic geothermal systems in northern Iceland. Building upon an extensive array of geological and geophysical datasets from the Theistareykir and Krafla geothermal fields, I plan to develop initial fracture network models and assess the relationship between faulting and fluid flow in the system. This could be extended to dynamic modelling of fluid flow with changing stress environments, coupled to subsurface pressure and temperature changes. This study aims at a better understanding of the geothermal reservoir boundaries, and how faults structures may control the subsurface fluid flow processes.
