The Geothermal Energy and Geofluids Group at the Institute of Geophysics in the Department of Earth Sciences, ETH Zurich, Switzerland, invites applications for a
PhD position to investigate solute transport in fractures using Laser-Induced Fluorescence (LIF) combined with Particle Image Velocimetry (PIV)

While significant progress has been made regarding fluid flow and solute transport behavior in non-fracture-based reservoirs, relatively little advancements have been made regarding transport in fractured formations, despite their importance for geothermal energy, geological waste disposal, and oil and gas production. 

The main goal of this PhD project is to investigate solute transport with fluid/solute channeling and/or hydraulic trapping within fractures and, particularly, within fracture intersections. The project focuses on solute mixing behaviors at fracture intersections. Synthetic bifurcating fractures produced by a 3D printer will be used together with the analogue (i.e., surrogate) fluid(s) to match the refractive index of printed solid. The project combines Particle Image Velocimetry (PIV) with Laser-induced Fluorescence (LIF) to simultaneously monitor the fluid velocity field and the associated solute concentration field in 3D.
The PhD candidate is offered a one-year fulltime position with -at good performance- the prospect of an extension with a maximum of three years (in total 4 years fulltime). Benefits, working hours, salary, insurance and pension are subject to ETH Zurich standards.
Highly motivated candidates with an MSc degree in hydrology, hydrogeology, geochemistry, engineering geology, or a related field are encouraged to apply. The candidate should have proven knowledge of conducting laboratory visualization experiments and/or developing/applying numerical models in a closely related field. Laboratory experience is a considerable advantage. He/she should be proficient in English and have excellent scientific writing and presentation skills. The candidate is an enthusiastic team player and has good communicational skills.
We look forward to receiving your online application including a detailed C.V., a motivation letter, diplomas, transcripts from all previous studies, and work certificates (if any). Please note that we exclusively accept applications submitted through our online application portal. Applications via email or postal services will not be considered. Evaluation of applications will start on December 1, 2017, and continue until the position is filled.
