Postdoctoral Researcher: Hydraulic stimulation and proppant behaviour in crystalline rock
The Chair of Engineering Geology and the BedrettoLab at ETH Zurich invite applications for a Postdoctoral Researcher position within the European research project UPLIFT, focusing on environmentally friendly hydraulic stimulation technologies in crystalline rock formations. The role involves experimental research at the Bedretto Underground Laboratory.
Responsibilities
* Plan, conduct and analyse hydraulic stimulation experiments, including proppant in vertical and horizontal boreholes (30–120 m scale) to investigate proppant transport, placement efficiency, and interaction with natural fracture networks.
* Assess the effectiveness of different stimulation strategies and proppant placement approaches under varying geological conditions in terms of permeability enhancement and fracture geometry.
* Collaborate with project partners conducting small‑scale laboratory experiments (GFZ) to interpret data and recommend design for full‑scale hydraulic stimulation operations.
* Contribute to project deliverables, report findings, publish results in peer‑reviewed journals, and present at international conferences.
* Coordinate closely with UPLIFT partners (GFZ, industry) and support alignment between experimental, modelling, and field activities.
Qualifications
* PhD in Engineering Geology, Geophysics, Geomechanics, Earth Sciences, Physics, Engineering, or a related field.
* Strong background in rock mechanics, hydrogeology, or reservoir engineering.
* Experience with laboratory experiments and/or fieldwork in subsurface environments.
* Willingness to participate in underground field campaigns.
* Skills in numerical modelling (e.g., fracture mechanics, fluid flow).
* Strong programming skills (Python, MATLAB, or similar).
* Experience with seismic or fibre‑optic sensing data is an asset.
* Ability to work independently and lead research tasks within a collaborative environment.
* Excellent communication skills in English.
Workplace
