Sophie initial background is in philosophy (M.Sc.). She is active in the training sector and more specifically interested in pedagogical models including e-learning, serious gaming and interactive storytelling, with a strong interest on the ethical issues raised by sustainable development and the transition to a more environmentally friendly society. She is bringing together these different topics in a doctoral thesis project at the University of Geneva.
Heading of International Petroleum Corporation’s (IPC) sustainability strategy, leading the company’s environmental, social, and governance (ESG) initiatives. Navigating complex global business challenges to effectively implement ESG principles.
MSc Mining Engineering
Vilde Jensen
Oulu Mining School
Student
For her Master thesis, Vilde studied the effect of cooling on rock mechanical behavior in granitic rocks at 5 km depth through numerical simulation. The aim was to understand the effects of thermal stresses on deep well integrity and stability under long term and continuous heat extraction. Vilde defended her Master thesis in November 2020 and obtained the highest grade.
Her research was hosted by AFRY Finland with financial support from the Bern Economic Development Agency.
Joint Interdisciplinary Project 2023
Well Engineering Partners – TU Delft
JIP – Joint Interdisciplinary Project is an interdisciplinary Master course at TU Delft where students work 10-week full-time in groups of five on a challenge identified by the industry.
In 2023, EAPOSYS teamed with Well Engineering Partners on solutions to strengthen AGS performances. In particular, the student team was asked to evaluate technical solutions for drilling and working fluids with self-repairing and sealing properties in the context of barefoot completion multilaterals of deep geothermal closed-loop systems.
The students explored solutions such as pre-treatment sealing before operation, effectiveness of such solution over time and effects of leakage and/or maintenance operations on energy production. Water-based solutions using various concentrations of sealant additives were investigated.
The aim of this project was to develop an analytical calculation module allowing the treatment of multiple wellbore sections along any pre-defined polygonal line geometries and parameters in a “vertically linear” geothermal gradient field. Analytical approaches allow for extensive and systematic parametric analyses. In the case of numerical approaches, such analysis is more difficult due to time consuming, intensive calculation resources requirements and discretization problems.
The analytical module was tested using input data from published numerical simulations or measurements. Results and/or measurements were confirmed to a fraction of degree.
Joint Interdisciplinary Project 2024
Well Engineering Partners – TU Delft
JIP – Joint Interdisciplinary Project is an interdisciplinary Master course at TU Delft where students work 10-week full-time in groups of five on a challenge identified by the industry.
In 2024, EAPOSYS teamed with Well Engineering Partners on questions around material investment, energy feedback and environmental externalities of Deep Geothermal Systems.
A team of 4 TUD Master students from different faculties established a framework for calculating the Energy Return On (Energy) Investment (EROI) for Deep Geothermal Systems (DGS). Two initial cases were made based on the framework demonstrating the high Net Energy potential of geothermal systems.
IMD 2025
EAPOSYS was honored to be selected for the prestigious IMD Startup Competition 2025, organized by the renowned IMD Business School in Lausanne, Switzerland. As part of the program, a dedicated team of six IMD MBA students collaborated with us over several months, focusing on stakeholder mapping for our innovative deep geothermal energy solution. The initiative provided valuable strategic insights and fresh perspectives, helping us strengthen our market positioning and engagement strategy.
A warm thank you to the IMD for this opportunity to participate to one of the most selective and rigorous business programs in the world!
In this work, Nermine and Nour, two master chemical engineering master students from INSAT performed a 5-month comprehensive study on Enhancing Closed-Loop Advanced Geothermal Systems with Nanofluids – A Thermal and Environmental Assessment. Thermal properties of selected water-based nanofluids (CuO, ZnO, Al2O3, SiO2, and SiO2/Al2O3) were modeled using MATLAB. A COMSOL simulation of a generic AGS loop was implemented to investigate thermosiphon behavior and serve as a baseline. Finally, a preliminary Life Cycle Assessment (LCA) was completed to evaluate first order environmental cost centers of nanofluids.
EAPOSYS is very grateful to Nour and Nermine for their dedication and high quality research!
