Benchmarking Seismic Source Models for Geothermal Operations.
Job description
We are seeking a highly motivated Postdoctoral Researcher who will be working on two closely related research projects addressing key subsurface challenges in geothermal energy production and CO₂ storage. The role focuses on the development, implementation, and benchmarking of advanced numerical models to better understand and manage induced seismicity, fault reactivation, and near-wellbore processes such as salt precipitation and hydrate formation. The work integrates processes across scales, from near-wellbore physics to reservoir- and fault-scale behaviour, and supports the development of robust, physics-based modelling tools for subsurface energy applications. Main repsonsibilities include:
- Design and implement benchmark scenarios for (shear) stress modelling along faults and seismic modelling in geothermal operations, supporting fault stressing and seismicity analyses.
- Establish validated reference scenarios for this benchmark with varying levels of complexity, including cases with analytical or semi-analytical ground truths.
- Develop accurate near-wellbore physical models for salt precipitation and hydrate formation during CO₂ injection, explicitly accounting for impurities in the CO₂ stream.
- Bridge near-wellbore, reservoir, and fault-scale processes through consistent numerical modelling and upscaling.
- Support model evaluation, comparison, and performance assessment across both projects, in close collaboration with internal and external stakeholders.
Job requirements
The successful candidate is expected to have:
- Background in geophysics, reservoir engineering, geomechanics, or a related field.
- Strong background in numerical modelling of subsurface processes, including fluid flow, geomechanics, or coupled multiphysics systems.
- Experience with seismic source modelling, induced seismicity, or fault mechanics.
- Familiarity with analytical and numerical modelling approaches.
- Ability to work with complex geological and reservoir datasets.
- Strong documentation and communication skills.
- Experience working in collaborative, research-driven projects is an asset.
Desirable skills include
- Experience with geothermal systems or subsurface energy applications.
- Experience with near-wellbore modelling, including completions, perforations, and damage zones.
- Knowledge of benchmark model development and model validation workflows.
- Ability to translate scientific concepts into practical modelling scenarios.
