Researcher PhD in Geosciences (open position from April 2022)
Using a patent from the CNRS, which describes one specific analysis of seismic waveforms reconstructed through ambient noise interferometric processes, we are developing new monitoring solutions for tracking fluid movements in the subsurface for industrial applications.
The use of seismic timelapse attributes to understand the change in the subsurface is an ever-evolving field, that has potential application in numerous domains, such as underground gas storage, CO2 geological storage, geothermal fields, H2 exploration, hydrogeology, etc.
We have launched in 2021 our first demonstrator project for the monitoring of one geological gas storage site. Our second development project, launched in early 2022, uses the same approach but in another context of shallow gas seep.
With the objective of better constrain the sensitivity of the seismic monitoring tools we develop, GeoLinks has recently entered the Seiscope consortium, thus gaining access to one of the most performant 3D seismic propagation modelling codes available.
We are now looking for an experienced researcher in seismic modelling and/or passive seismic interferometry to undertake seismic simulation work as well as participate to future developments within our R&D team.
The researcher will undertake modelling and simulation work of seismic wavefields using existing codes developed by the SEISCOPE consortium. During the first year, the research work will consist of achieving the following steps:
1) Mastering the elastic modelling capabilities of the Seiscope code including mesh generation, model design and simulation of the complete wavefield for a given source distribution. The workwill first be carried out on simple media (e.g. tabular 1D), and afterwards on media of increasing complexity (2D, and later on 3D).
2) Developing tools that will allow interfacing and transfer of information between the Seiscope modellingtools output and the python-based analysis tools developed at GeoLinks.
3) Participate to the developmentof an adapted formalism to simulate seismic wave propagation on 3D media with changing properties (attenuation, seismic velocities etc..), with respect to the different industrial case (gas storage, hydrogeology etc…) .
The researcher might also contribute to the development of specific data processing tools as well as real data analysis of pilot projects.
